In the age of Claude Code and other MCPs, the last thing I want is my commit history to be mutable. I've added instructions to Claude which make a commit before each modification with a summary of the conversation that caused the change. Once I'm happy with the work, I squash the commits and push up. (Which I believe is more or less equivalent to the jj workflow.)
I just don't have enough pain points with Git to move to something new. I don't have a problem remembering the ~5 commands I need most on any given workday. Between stashes, branches, temporary commits I later rebase, and recently worktrees, I don't lack for anything in my usage. It's universally used across both my public and corporate life, and neither does anyone need to learn a new tool to interact with my code base, nor do I need to deal with possible inconsistencies by using a different frontend on my end.
It's cool that it exists, and it's impressive that it is built on top of git itself. If you (like the author) want to use it, then more power to you. But I have yet to be convinced by any of these articles that it is worth my time to try it since nearly all of them start from a point of "if you hate Git like me, then try this thing".
If anyone has a link to an article written from the point of view of "I love or at least tolerate git and have no real issues with it, here's why I like JJ," then I'd be glad to read it.
If you've ever lived in a world of stacked commits with develop on main (i.e. not gitflow, no feature branches), combined with code review for every commit, git will soon start to aggravate you. Git doesn't make rebasing a chain or tree of commits pleasant. Git records merge resolutions and can reuse them, but it doesn't do the same thing for rebases, making them more repetitive and tedious than they should be. When you address comments on earlier commits in a chain, you need to rebase after. Git's affordances for rebasing aren't great.
And when you rebase, the commits lose their identity since commit hashes are content-addressed, despite having an identity in people's minds - a new revision of a commit under review is usually logically the same unit of change, but git doesn't have a way of expressing this.
jj, as I understand it, addresses these pains directly.
The best thing that could come out of jujitsu is git itself adopting the change-id system (which I believe I read somewhere is being considered). If you actually take time to learn your tools and how they're intended to be used, there's really not reason to learn jj IMO
git is both a (bad) UI and a protocol. Jujutsu is a UI on top of git (the protocol).
There's nothing wrong with taking the time to learn how to use a bad UI, especially if there's no other option. But don't mistake your personal mastery of git for evidence that it's better than jj.
In all likelihood, the git proposal you allude to would not extend further than adding a bit of persistent metadata that follows commits after "destructive" changes. And even then, it'd be imperatively backing into the change-as-commit-graph data model rather than coming by it honestly.
> If you actually take time to learn your tools and how they're intended to be used, there's really not reason to learn jj IMO
This is like saying if people take the time to learn curl, there's really no reason to learn Firefox.
And it doesn't suggest to me that you're all that familiar with jj!
- automatic rebasing! goodbye to N+1 rebases forever
- first-class conflict resolution that doesn't force you to stop the world and fix
- the revset/template languages: incredibly expressive; nothing like it in git
- undo literally any jj action; restore the repo to any previous state. try that with the reflog...
No amount of learning git nets you any of these things.
Where jj shines is advanced workflows that aren’t practical with git. If you aren’t interested in those then it doesn’t give you as many benefits over git.
If you are breaking down your features into small PRs, stacking them, etc…, then jj is super helpful.
I’m also fine with git, and have used mercurial and p4 before. I think simplicity is better in this case. I do think with more and more generated code inflating the codebase with high velocity, we need to find a better way to merge conflicts.
I don’t hate git either but you’ll meet very few people who will claim its UX is optimal. JJ’s interaction model is much simpler than git’s, and the difficulty I found is that the better you know git, the harder it is to unlearn all its quirks.
I don't hate git, I like it fine and, until recently, used it exclusively on all my projects (I still use it non-exclusively). Here's an article that's written from that viewpoint:
Idk man, the first two paragraphs
of the article very much make it sound like you hate git.
> Over the past few years, I’ve been seeing people rave about Jujutsu, and I always wanted to try it, but it never seemed worth the trouble, even though I hate git.
I read that more as "aw, fuck it, I'm starting over". Then, given what it's doing, "fuck it" -> "fuckgit" makes sense.
But hey, it's not my alias. I'm just saying that the way I read it didn't suggest hate, just a little cleverness. I can't speak for what the author was thinking.
Yeah I definitely hated Subversion, which helped push me to try Git back in the day. Actually, back then I was an `hg` guy. That battle was lost long ago though.
I think you linked to the same post as OP, though?
I wrote the post, so that's a post from the perspective of someone who doesn't hate git :P
I used bzr after SVN, but my larger point is that it's all fine, the question was whether you want to go through some short-term learning for long-term gain, or if you want to keep using what you know. Either is fine, I'm still using vim as my editor, for example.
SVN was not fine. Branching took forever (all the copying). And the space that required ... In fact, lots of things took forever on large-ish repos. Remember that everything required the server and network and disk speeds were slower back then. And just a commit could destroy your work if you got stuck in a conflict resolution. So you'd have to copy all the files you changed to a backup just in case, then delete them if the resolution went OK etc.
Was it better than CVS in some way? Sure.
But git is just better in so many ways. Back in the day I used git exclusively with git-svn at a place that was still stuck with SVN and I had a blast, while everyone else didn't. I just never had any of the problems they did.
I'm not entirely sure what pain people speak of with git. I found the transition very natural. And don't come talking to me about the "weird command syntax". Some of that was specifically to be compatible / "intuitive" / what they were used to for people coming from tools like SVN.
Sure you gotta learn about "the index", understand that everything is local and that you have an origin and local copy of all the labels (also sometimes called branches or tags) you can attach to commits. That's about it for the normal and regular use that someone would've had with SVN.
Except that it has to first be true that jj is better ;)
You start out the article with hate for git without explaining what you actually don't like, then here on HN say "I don't hate git". A command called `fuckgit`? Because you need to re-clone? What are the things you commonly do that require this? I've never encountered it. Maybe you're just too advanced a user for git and jj really is better for you. But for us lowly regular users I really do not see an issue.
Some of the benefits you tout, like "editing a commit and you don't need to commit it yourself"? I'm sorry but I want to be the one in control here. I am the one that says "I'm done here, yes this is the new version of the commit I'm comfortable with". I've specifically forbid Claude to add, commit, push etc. for example.
It also breaks your "you need to stash" argument. I don't stash. I just commit if I have something WIP that needs saving while I work on some other emergency. There's no reason not to just commit. In fact I do that all the time to checkpoint work and I amend commits all the time. It's my standard commit command actually `git commit -a --amend`.
Automatic "oplog" of everything Claude did, IDE style: sure, maybe. Though I've yet to see that need arise in practice. Just because I have Claude et. al. now, I don't believe changes should be any bigger than they used to. Nor should my "commit early, commit often, push later" practice change.
> You start out the article with hate for git without explaining what you actually don't like
I start out the article saying I never understood git, and why does it matter what I don't like? That would only matter if I were trying to say that git is bad, but I'm not making a comparison. I just think jj is better-designed, and that you should try it.
> Some of the benefits you tout, like "editing a commit and you don't need to commit it yourself"?
I never said that's a benefit, I just said that's something jj does differently. I `jj commit` when I'm done with some work anyway.
> It also breaks your "you need to stash" argument. I don't stash. I just commit if I have something WIP that needs saving while I work on some other emergency.
In that case, you'll like jj, as it handles all that for you.
Your comment is coming off as a bit defensive, I didn't write my article to attack git. If you like git, keep using it, I prefer jj and I think other people will too. It's hard to get started with because its workflow is different from what we're used to, so I wrote the tutorial to help.
I didn't write my article to attack git [...] I wrote the tutorial to help.
Except you didn't write a tutorial. You wrote an "I hate git and jj is better and if you think otherwise you're wrong" article.
Blue speech bubble with literally the text: "If you don't like Jujutsu, you're wrong". This is text. There's no "tongue in cheek" voice and body language here, even if potentially you meant it that way. But given how the article itself starts, I don't think there was any of that to transport :shrug:
Needless to say, I just don’t get git
Actually, it does bear saying. And I do think that if you say "everyone that doesn't think jj is better is wrong" you have to explain what you really don't like or get. No it's not needless, because not everyone has your experience. I really do not understand your pain points unless you explain them, because I've never felt them. Either because I did understand the part you didn't, because I don't need to understand that part to use it well (cutting the decision/knowledge tree in your head is a skill by itself I've found over the years - sometimes you do have to accept magic! E.g. I don't need to understand exactly how any specific LLM works to use it well) or because I simply never had a need for the kinds of feature that trip you up.
> Needless to say, I just don’t get git. I never got it, even though I’ve read a bunch of stuff on how it represents things internally. I’ve been using it for years knowing what a few commands do, and [...]
> If you don't like Jujutsu, you're wrong
It would be much more convincing if they had any idea of git that they were comparing it to.
I have been trying Jujutsu for a few weeks. It's cool and I like trying new things. I wouldn't say that it's so much better than git, though; there is nothing that I miss in the projects where I use git.
On the other hand, I have issues with Jujutsu, one of which completely prevents me from using it in some projects:
* No support for git submodules. One can dislike submodules as much as they want, if I need to contribute to a repository using them, I can't use Jujutsu.
* The signing support is very annoying with a security key. Even if I configure 'sign-on-push', it will access the security key every time it tries to check the signature, which is pretty much every `jj st` or `jj log` after something has changed locally. I don't need to check my own signatures, IMO they should be checked on fetch and on push.
* There is no way to configure a 'defaultKeyCommand' like in git, which I now rely on (because I have multiple security keys).
I really loved jujutsu for the few weeks that I used it.
However, I did find all my tools that rely on Git (eg Gitlab CLI that can open merge request from the current branch) breaking because JJ operations result in detached head in Git.
In addition, mixing Git and JJ will result in your repos becoming really slow when you do need to run some Git operation.
One of the bigger selling points of JJ just wouldn't work so well without larger team buy in for me: the ability to push stacked PRs.
I like the idea of it, but there's so much inertia around typical git workflows that revolve around the GH pull request model (with the only difference being the use of trunk based dev or some git-flow like branching strategy) that it'd be hard to change without a lot of buy in.
I still think back to Phabricator and its approach to code review, noting that it sadly never got wider traction despite having notable benefits over a completely entrenched status quo.
What is there not to _get_, honestly? And why is jj so easier to get?
The author seems to focus on how great it is to make changes to your commit history locally, and that you shouldn't worry because it's not pushed yet.
The thing is, I don't want automatic. Automatic sucks. The point of version control is that I am able to curate my changes. The guards and rails of git is what makes me feel safe.
I am still failing to see why JJ is superior to git, or whatever.
There are some convention people follow when working with git to make it safe to use. But those aren't git's features -- they are ways to avoid confusion.
If you don't want automatic, you shouldn't use git. It does too many things automatically, like update your branches' heads whenever you commit, for example.
And if I don't want that I can detach the HEAD. This isn't to much different. The only thing that changes by using branches is that you have a nice name, it prevents the commits from being GCed and it provides a default name on push.
I have been trying to use jj for a couple months now, but hitting some friction with my company’s GitHub PR workflow. Specifically, after the PR is merged, the next time I fetch I always end up with a ton of conflicts. It gets hard to clean them up, so I often end up abandoning all mutable commits to start fresh.
I feel like I’m doing something wrong, as I haven’t seen this mentioned in any tutorials, but I don’t know what! :-/
I’ve been using jj for a few months now and still love its workflow, but I keep running into the same problem you mentioned. The advantages of jj far outweigh this issue, so I’d really like to figure out a clean way to avoid these conflicts.
for me, squash merges are enforced on github, and usually results in some weird / empty commits if i rebase a local stack after pulling in changes with part of the stack merged.
> Jujutsu, in contrast, is more like playing with Play-Doh. You take a lump, cut it into two, shape one piece into something, give it a name, change your mind, give it another name, take a bit of the second piece and stick it on the first piece, and generally go back and forth all around your play area, making changes.
I love this description and it describes how I work with git. When I’m doing things locally I’m constantly committing small wip commits. When I get something the way I like it I’ll interactive rebase/just back it all up, and then create the perfect little boxes. I guess I should try jujutsu since it sounds like it might be even more for me. Although if you can’t get to the perfect boxes at the end I don’t know if I’d like it.
I think you would love jj then. It is dead-simple to just move things around - branches/bookmarks, commits and even single lines of code within a diff.
That's how I feel like working with git locally using a combination of basic commands and gitup (https://gitup.co/), that may be why I couldn't really get the selling point of jj when I tried it a couple weeks ago.
The only part that piqued my interest is merges being always successful and conflicts just sitting in the tree, waiting patiently to be resolved... It's the next logical step after being able to commit without synchronizing when we all moved away from SVN.
I use a gui for 90% of my workflows. Another 9 percent points are hitting back in my console history to rerun commands, never mind if git or jj or POSIX that affect my working dir or index state.
What am I supposed to do, use the UI plus jj, and prompt an LLM to use which: git, or jj, in case I am too lazy to think of the right command in the remaining one percent of cases?
But in general, I like the "less states and DVCS features than git" approach, but would not switch back to mercurial just to avoid the whole "should we rebase or create merge-commits" discussions in our teams due to having a single default that might not be optimal for everyone, but just works.
use jjui - its an absolute pleasure to use as you dont need to know anything beyond arrow keys and some keyboard shortcuts (which you can also find in the ? help menu). https://github.com/idursun/jjui
If it doesnt do anything you already need, then the maintainer is likely to add it quickly - its rare to find someone so responsive
I feel like anyone who spends just a couple of hours learning git will have a much better mental model than the crappy "Assembly line" model from the article.
Your real mental model of git should be an acyclic directed graph where the nodes are commits and the edges are ancestry. Commits represents snapshot of the project's state. Tags and branches are just text pointers to commits in the graph.
If you use this mental model, suddenly things like git rebase or git reset become far less mysterious and arcane since they are just simple graph operations. Like `git reset --hard X` means "Make current branch's text pointer point to X"
I understand git at a pretty deep level. I still very much prefer jujutsu. Its rebase is just so much more powerful than git. I regularly work on top of octopus merges in jj of all my in-review parallel PRs and when I want to rebase them all and the octopus merge and the various anonymous branches on top it takes 1 command. It’s so much more powerful than git it’s crazy.
I think the author is one of those folks who were able to fully grasp the beauty of the Git data model for the first time by switching to Jujutsu. It makes it easier to see the “DAG of commits” vision than Git with its index and stashes and confusingly named commands with fifty flags.
Yeah, exactly, and I've fruitlessly read too many guides on git's data model.
What was holding me back turned out to be the fact that git has too much magic (it updates branches automatically when you commit, rebasing "does stuff", conflict resolution was just arcane).
Jj exposes all that into simple, composable principles, making everything click.
Totally agree on the DAG point of view, but I would argue that for different people you need different analogies/models to make it click. I would argue that pointing towards graph theory might help people that have a formal CS or maths education, but not necessarily folks that went through bootcamps, switched from design roles, have a biology background (e.g. bioinformatics) or do statistics (e.g. in medicine or psychology)
Always the same starting point: "I don't understand how git works".
If you can't understand git, one of the most used tool in the whole industry, this is a *you* problem. You MUST take the time to understand how it works properly. Every job you'll get and every projects you'll work on will use a Version Control (at least I hope).
Abstracting this knowledge by using a tool that does things quite differently won't help you at all on the long run.
I am a git expert and I very much prefer jj. It enables workflows that are impractical with git. It’s hard to even imagine these workflows if you only use git because your thinking is constrained by the limitations of your tools.
Git rebase is like programming with punch cards compared to jj’s rebase being like writing Python.
> You MUST take the time to understand how it works properly.
Unfortunately, I agree.
It is both ubiquitous and so unnecessarily complex. The fact that all developers are required to memorize at least a few of its inscrutable incantations reflects poorly on the industry and on the judgement of its practitioners.
Ok, I can get behind JFK's quote "We choose to go to the Moon not because it is easy, but because it is hard" - but do we have to apply the same quote to git? The way I see it, git is a tool and not a goal in and of itself. If there is a tool that does the same thing in an easier to use way (and can work with git repos), why use git? Of course, using VCS is part of the job description of almost every developer in the world, but git !== VCS...
"if some students fail the test, the problem is of the students, if many do, is of the teacher".
Git is a bad teacher. There are a lot of things that are profound yet easy to grasp when learned and other things are called bad products. Git is one of them.
I have primarily used git in the terminal for more than a decade. I also used magit when I was primarily working in emacs (magit's great!). I now primarily use lazygit. While I'm not a fan of the whole UI, this is the only git tool that makes me go super fast while creating a near-perfect commit history. I tried using jj but immediately stopped after installation as it required a learning curve that I wasn't ready to commit to yet.
you might consider trying again, but do so with jjui (https://github.com/idursun/jjui) - very similar concept to lazygit and makes working with (the already simple) jj even more seamless and intuitive
I don't really understand the appeal of jj as someone who uses sublime merge [0].
It has good support for submodules, a lot of the editing commits (messages, squash, move etc...) is really easy and I can also see and edit my stashes directly. Is there any benefit to jj compared to this?
Until jj supports `git rebase -x "cargo check --deny warnings"`, it's useless to me. jj has primitive support for fixing individual files that changed, but it cannot work on any linter or formatter that depends on other files.
"Git is too hard" is never a good argument to promote the use of a different tool.
I use git on the terminal exclusively, never had an issue amending a commit or rebasing a branch, or even dealing with conflict resolution most of the time I just use one of the automatic strategies.
> "Git is too hard" is never a good argument to promote the use of a different tool.
Really? Pointing out that a tool is difficult to use seems like an excellent argument to promote the use of a different (supposedly simpler) tool.
Specifically in the case of git, I'm glad it was not difficult for you, but it is undeniable that it is a very difficult tool for many people to learn.
git rebase|cherry-pick|revert --abort and git reflog can solve pretty much all of my problems with git repos in weird states, and any advanced Git user should know them.
what im most impressed by when I read the comments to jj-related threads is how many people are handwriting assembly code.
I come to this conclusion because there's always a large amount of people saying "if you dont understand, let alone have mastered, git, then you dont get to have an opinion"
So, clearly these people similarly dont use ease-of-use abstractions like programming languages
It's cool that it exists, and it's impressive that it is built on top of git itself. If you (like the author) want to use it, then more power to you. But I have yet to be convinced by any of these articles that it is worth my time to try it since nearly all of them start from a point of "if you hate Git like me, then try this thing".

jj, as I understand it, addresses these pains directly.
Since when does rerere not work with rebase anymore?
There's nothing wrong with taking the time to learn how to use a bad UI, especially if there's no other option. But don't mistake your personal mastery of git for evidence that it's better than jj.
In all likelihood, the git proposal you allude to would not extend further than adding a bit of persistent metadata that follows commits after "destructive" changes. And even then, it'd be imperatively backing into the change-as-commit-graph data model rather than coming by it honestly.

The thing is, I don't want automatic. Automatic sucks. The point of version control is that I am able to curate my changes. The guards and rails of git is what makes me feel safe.
I am still failing to see why JJ is superior to git, or whatever.
There are some convention people follow when working with git to make it safe to use. But those aren't git's features -- they are ways to avoid confusion.
I feel like I’m doing something wrong, as I haven’t seen this mentioned in any tutorials, but I don’t know what! :-/
Can you try it on a fresh clone and see if it still happens?
I love this description and it describes how I work with git. When I’m doing things locally I’m constantly committing small wip commits. When I get something the way I like it I’ll interactive rebase/just back it all up, and then create the perfect little boxes. I guess I should try jujutsu since it sounds like it might be even more for me. Although if you can’t get to the perfect boxes at the end I don’t know if I’d like it.
jjui (https://github.com/idursun/jjui) makes it all that much easier too
The only part that piqued my interest is merges being always successful and conflicts just sitting in the tree, waiting patiently to be resolved... It's the next logical step after being able to commit without synchronizing when we all moved away from SVN.
What am I supposed to do, use the UI plus jj, and prompt an LLM to use which: git, or jj, in case I am too lazy to think of the right command in the remaining one percent of cases?
But in general, I like the "less states and DVCS features than git" approach, but would not switch back to mercurial just to avoid the whole "should we rebase or create merge-commits" discussions in our teams due to having a single default that might not be optimal for everyone, but just works.
If it doesnt do anything you already need, then the maintainer is likely to add it quickly - its rare to find someone so responsive
Your real mental model of git should be an acyclic directed graph where the nodes are commits and the edges are ancestry. Commits represents snapshot of the project's state. Tags and branches are just text pointers to commits in the graph.
If you use this mental model, suddenly things like git rebase or git reset become far less mysterious and arcane since they are just simple graph operations. Like `git reset --hard X` means "Make current branch's text pointer point to X"
What was holding me back turned out to be the fact that git has too much magic (it updates branches automatically when you commit, rebasing "does stuff", conflict resolution was just arcane).
Jj exposes all that into simple, composable principles, making everything click.
Always the same starting point: "I don't understand how git works".
If you can't understand git, one of the most used tool in the whole industry, this is a *you* problem. You MUST take the time to understand how it works properly. Every job you'll get and every projects you'll work on will use a Version Control (at least I hope).
Abstracting this knowledge by using a tool that does things quite differently won't help you at all on the long run.
Git rebase is like programming with punch cards compared to jj’s rebase being like writing Python.

Unfortunately, I agree.
It is both ubiquitous and so unnecessarily complex. The fact that all developers are required to memorize at least a few of its inscrutable incantations reflects poorly on the industry and on the judgement of its practitioners.
Git is a bad teacher. There are a lot of things that are profound yet easy to grasp when learned and other things are called bad products. Git is one of them.
Moreover, you can use jj almost completely seamlessly with a git repo - including PRs etc to github. I do it daily and no one is the wiser.

Really? Pointing out that a tool is difficult to use seems like an excellent argument to promote the use of a different (supposedly simpler) tool.
Specifically in the case of git, I'm glad it was not difficult for you, but it is undeniable that it is a very difficult tool for many people to learn.
I come to this conclusion because there's always a large amount of people saying "if you dont understand, let alone have mastered, git, then you dont get to have an opinion"
So, clearly these people similarly dont use ease-of-use abstractions like programming languages
