I really want to find reasons to like this but it’s probably some of the worst product marketing I’ve seen. And something this significant really does need to sell itself hard if you’re going to get enough people in a project team to agree to switch away from git
>the performance of git isn’t a bottleneck for agents.
Eh, it depends on the workflow. Especially if you have certain stack based workflows. Worktrees are kinda half solution here but depending on the repo type and if you are dealing with LFS or sparse checkouts, I've had agents struggle really hard to work through a stack or rebase things without a lot of thrashing or being IO bound by just stumbling into operations in a boneheaded way. Now I have AGENTS.md/skills/hooks gaurdrails littered about to try and work around things.
I've built my own workflow for using agents on git, as i now often have to do changes across repositories, or in the same repository for different tasks. I could use worktrees, but I'd rather invert it, give agents the ability to have a workspace, that they pull repositories into, create branches as they want, commit on main it doesn't matter. the agents don't bother each other, and when i finally have to merge, conflicts are either resolved, or it is just smooth sailing.
The tool is called gitnow. it is honestly quite simple, just create a project, add the repositories you want and get to building. I've found having another claude chat or whatever use the tool to great success coupled with zellij, but could also be zed, tmux or whatever.
Secondly it also pretty much solves the problem of the agent dumping memory files everywhere, they now basically have a scratch space that is theirs, where they can keep their tasks, and just update the repositories as needed.
Use gn the shell after eval if you use it, it will actually invoke cd, instead of creating a subshell.
I am curious, how do you handle latency issues for on demand access? I saw you use FUSE (and FSKit), and from my experience it is pain to make filesystems in userspace work on-demand over WAN because a) latency, and variable RTT; and b) you can't saturate the wire and aggressively read ahead things, otherwise native apps will freeze, lag, or just make the UX unpleasant, especially if there are too many placeholder files, or large files with random jumps in them.
Haha I wish, but I've been working on VCS's separate from git for a while now. Although I do love git, I've wondered for years before agents if something could be made using something different, rather than building something on top.
I'm also secretly a massive fan of Dr. Hipp and his work on FossilSCM [1]. I love a bunch of his design decisions there and wanted to apply them to a new system.
Back in the day, 2020, the effort to create a program/website/service was the prohibiting factor, which meant the sediment remained at the bottom of the barrel where it belonged.
Now, every brain fart is published as a finished product no one wanted.
I would recommend just linking to a few sentences that say how Oak is different than Git, rather than a personal backstory. (https://oak.space/docs)
My initial reaction is if this is not something than could be built on top of Git, rather than replacing it. Describe the data model - what is a "commit", what is a "branch" ..., if the same as git, then why not reuse.
Ah thanks - I forgot to change the top link. In this case I think https://oak.space/oak/oak is probably more enticing to the community because they get to see what it actually looks like - so I've used that URL instead.
I have always wanted a version control system that was basically Emacs/Vim/Neovim's undo-tree[0] but persistent and social. Why do I have to manually talk to git? You are a computer, track every modification I make while editing and let me decide (or help me decide) on what a checkpoint is.
Seconding Jujutsu! I've been working to add Jujutsu support to basically every open-source tool and framework I use, including the agentic ones [0]. While it doesn't work for everyone, I've found it can really work for some people. (like myself)
It's absolutely great for keeping a bunch of exploratory changes alive, quick prototyping, etc. as I tend to do with basically every source I have on my machine. I don't have to think at all about the stuff I hate about git (babying the index, being careful to amend and etc. right the first time because undos are annoying, etc.)
is there some more information about DeltaDB? this seems to be an early access feature and not something available at the moment but I would be interested to learn more about it.
Certainly an interesting project although I am wondering what makes the benefits mentioned agent specific? You have mentioned performance improvements which is great but in that case would it not just be a better vc than git in general? what perks only work with agents that wouldn't work with individuals?
Thank you! The bet we're making is that agents will need to work on tasks much faster and with more parallelism than humans do with Git right now so these performance metrics will matter more. Git is awesome for human work so I'm not sure these metrics really matter than much to people. But also for agents, worktrees are not the best (can't work on the same branch in multiple places) and also the speed at which branches/PRs are created, need to be merged, etc. will need to be way faster and simpler since keeping up-to-date with how fast things are being modified is really important.
Many things were forever until they suddenly died, but I think this is especially true for git.
I'm not saying this as a git hater, quite to the contrary. I think git is great. I also think git is an ill-fit for the majority of modern commercial software projects and there will be a breaking point where companies realize that and move on.
Git is great but if you really haven't found any reasons then you haven't looked at all. From large files to sub modules to hook permissions and file permissions... The list goes on and on about what where git falls short.
There's plenty of workarounds too, but that's what they are. Workarounds.
jj does not have large file or submodule support, but it does intend to in the future (you can read their design docs). Right now it's git compatible, so I'm not sure how 'permissions' would be stored compatibly, or what that means. I'm guessing ownership and xattrs
2. rebase based merge strategies - our team has 50+ devs across three continents merging into monorepo with teams maintaining submodules. By the time your merge request passes CI it has to be rebased. People are literally holding off on reviewing merge requests to make sure their own changes get in first
3. permissions for subdirectories/assets. some necessary code/modules are highly regulated and company secrets. Git cant lock certain directories based on who clones the repo
4. Agentic coding - if you don't commit then your changeset after each request is lost. JJ solves this. You could just say to commit after every request then squash the commits. But, I think this is an ergonomic argument
5. Maybe it's just my experience, but git-lfs is pretty annoying to manage on large teams and changing files to/from lfs. often easier to just delete and clone again
6. git blame on non-meaninful changes. Running a code linter to add/remove whitespace makes git blame return who ran the linter rather than who wrote the code
7. self-reported identity. every time we get new laptops (because they buy the cheapest POS) devs forget what they set for 'username'. so it ends up being 3-4 different identities with the same email
to be fair, #2 exists because monorepos and submodules are somewhat antithetical concepts. A monorepo is supposed tobe the single source of truth for the codebase, while submodules are pointers to external repos with their own history. That alone will increase the source of churn for teams that are constantly merging.
2. That has the smells of a wrong code architecture. If change request leads to unneeded code conflicts, you need to rework your code architecture.
3. That’s valid, but why not create libraries out of those modules?
4. Valid. But I think the issue is on the agent side. Git has already all the features to make those happen, it’s the agent that is not integrated with git.
5…
6. Either than sweeping changes (adding a formatter, changing config,…) There’s no need for formatting changes to be its own commit in the main repo. I usually add a check to prevent inconsistent formatting.
7. The git history has the previous username and email recorded alongside each commit.
1. Ease of use. Other VCS have more consistent command line interfaces; Git's interface has to be studied. In practice, people end up using GUIs with missing functionality and then end up searching for help, and a lot of real experts come to rely on powerful wrappers like Magit, LazyGit, or JJ.
(Compare to Mercurial, Fossil or Git; those systems have consistent and usable interfaces. There's much less demand for wrappers or LLM tooling since they're easy to use already.)
2. Preservation of history. Two common commands - git rebate and git push -f - cause commit history to be lost, sometimes permanently. ("Just be careful" and "Just don't use those commands" are useful pieces of advice for an individual, and virtually impossible to enforce over groups.)
3. Conflict resolution. Git forces the user to resolve conflicts ASAP so we often lose information about A. What the conflict exactly was, and B. How the individual resolved it. Most VCS have this issue; JJ allows you to commit the conflict and solve it in a separate commit, which is nice.
1. Usually people have no mental model about versioning other than “draft-1, draft-final, final, final2, final-final,…’. Because they don’t care about requirements and design decisions documentation, auditing changes, and release management. Git provides a set of tools for solving those. Wrappers are for when you have your own workflow for those needs and have a good understanding of git.
3. The goal of writing code is to have working software. Conflict messages are like compiler warnings, better have them than getting errors slipping by unnoticed. If A conflict with B, the root cause is often a design conflict, which means that the design of the software is inconsistent.
The conflict only matters as long as it’s not been solved. For each commit, the design of the software need to be consistent, and the succession of commit describe the evolution of the design. A is not lost, B is not lost in the case of a merge and may stay for a long time when rebasing. C which solves the difference between A and B (and may replace B) is also consistent. I don’t care about inconsistency.
How’s it an ill fit? Outside of large monorepo things, which are not the majority of modern commercial software projects, the main complaint I hear is the learning curve. But LLMs should be addressing that fairly well.
I wish we as a society would stop using random words for products. "Slacked about Oak, but they need in Fizzle. The deck's in Slate, the assets are in Vault, the timeline's in Pulse, the copy's in Quill, the build's in Forge, and the launch party's already in Ember."
seems like an interesting idea. the only friction would be to get people to use it instead of git, however i believe it will happen slowly, more people trying it and recommending it to others.
There are git clients for perforce, hg, svn and so on[1]. Oak' developer (or the community) could always develop a git frontend for users who prefer that .
Totally agree. This is going to be the hardest dev tool to get people to switch, but we're trying! I think there's going to be many more players in this space in the next year or so. It'll be interesting to see what shakes out.
What I want from a version system is to capture event in history not like changes as a files but as events that capture a process.
If I split a file in two I still want to be able to see blame correctly for the author of the function, not one file as freshly created and the other with a bunch of deletes. I wish commits could be folded into larger commits so that you can still capture the individual changes but also not see them by default when looking at the history of a file.
Just a more human centric perspective on change history where it captures the way we talk and think about changes.
"I wish commits could be folded into larger commits so that you can still capture the individual changes but also not see them by default when looking at the history of a file."
Fossil merges do this. More people need to use Fossil; it's got a ton of great ideas.
"If I split a file in two I still want to be able to see blame correctly for the author of the function, not one file as freshly created and the other with a bunch of deletes."
Now this is a good idea that I've never seen in a VCS.
> "If I split a file in two I still want to be able to see blame correctly for the author of the function, not one file as freshly created and the other with a bunch of deletes."
>

There's a reason no one has done that, the VCS would have to have a semantic understanding of what it's tracking. I'm sure that's possible, but I think would see extremely limited success. Honestly, it may have even been done for proprietary languages and VCS systems that have since faded into obscurity.
I'd settle for searching the git history for a particular regex/string and then running a blame on that.
1) An “easy” way to implement this would be to treat the original file as the parent to both files. You can add a new command “split” if needed to mark the new file as a fork of the existing file.
2) language sensitive version control seems like the next thing. We need like an LSP for VCSes.
If I run blame on the new file the will I see the commits made by the original writers? Will it find the same code if it was written independently? It’s not about find copies it about recording changes to a code base as an artifact and not to files. The closest git has is limited rename support.
Planning on some monorepo features soon that should solve some submodule problems but haven't approached yet. I have some new ideas here. And yes, no separate LFS system!
I'm a little confused by this but I assume you're talking about marking files for LFS (.gitattributes)? For us, we chunk every file (even if it's a single chunk) so every file is stored in the same way -- it's just data to us. But let me know if I got your question wrong.
Yes Lore looks awesome! I was previously working on a VCS for gamedevs -- that space definitely needs something better than Perforce haha. My comment would be that I think you need to nail a new GitHub + Git to really be successful in the space and I'm not sure Epic is focused on this. I wonder if Lore will turn out similar to Unity Version Control which is very specialized to Unity workflows or something more general. Definitely love what they're doing though.
It's kind of like replacing Wordpress. Sure, you can make a better alternative. But replacing an entrenched player that has been there for at least a decade will be almost impossible.
I love jj! Martin is really awesome and love his work. I know they're using a VFS backing inside Google for their monorepo, wonder if we'll get some of those cool features on the outside.
* The core idea sounds interesting. Make it the first paragraph, not paragraph seven.
* Spend more words describing what makes Oak different.
* "I built a version control system in my free-time called Jam". You probably didn't name your free time. "I built a version control system, called Jam, in my free time."
Just "I built a version control system called Jam". The free-time thing is good for a history page but the homepage needs to tell the important part (you've got history and expertise in this subject) and then move onto what the vision is for Oak and what kind of help you need.
Lots of self-promotion, but no concrete comparisons where this tool does a better job than git.
The only thing to go on is this single sentence: "With virtual mounts, agents locally and in the cloud no longer need a full copy of a repo to get working."

What is git not suited for in modern development? I haven't found any reasons.
Game development, with very large assets. Also, git is pretty terrible with non-text files.
Seconding this for geospatial dev projects, which may have absolutely massive binary data files.
You're diffing very large assets?
Git is great but if you really haven't found any reasons then you haven't looked at all. From large files to sub modules to hook permissions and file permissions... The list goes on and on about what where git falls short.

1) An “easy” way to implement this would be to treat the original file as the parent to both files. You can add a new command “split” if needed to mark the new file as a fork of the existing file.
2) language sensitive version control seems like the next thing. We need like an LSP for VCSes.
git actually does this. `git diff --find-copies`
If I run blame on the new file the will I see the commits made by the original writers? Will it find the same code if it was written independently? It’s not about find copies it about recording changes to a code base as an artifact and not to files. The closest git has is limited rename support.
Yes, if you run `git blame -C`.
Grammar nitpick: "anyways" should almost awlays be "anyway"

"awlays" should almost always be "always"
Does this try to solve the biggest problems with Git: submodules and LFS?
Planning on some monorepo features soon that should solve some submodule problems but haven't approached yet. I have some new ideas here. And yes, no separate LFS system!
> And yes, no separate LFS system!
Awesome. How does one decide which files should be stored externally, and manage that? And where is that decision stored?
I'm a little confused by this but I assume you're talking about marking files for LFS (.gitattributes)? For us, we chunk every file (even if it's a single chunk) so every file is stored in the same way -- it's just data to us. But let me know if I got your question wrong.
This sounds similar to Epic Games' Lore approach - have you seen what they're doing?
https://epicgames.github.io/lore/explanation/system-design/ if not
Yes Lore looks awesome! I was previously working on a VCS for gamedevs -- that space definitely needs something better than Perforce haha. My comment would be that I think you need to nail a new GitHub + Git to really be successful in the space and I'm not sure Epic is focused on this. I wonder if Lore will turn out similar to Unity Version Control which is very specialized to Unity workflows or something more general. Definitely love what they're doing though.
It's kind of like replacing Wordpress. Sure, you can make a better alternative. But replacing an entrenched player that has been there for at least a decade will be almost impossible.
you don't need to replace, you just need to find your niche, then expand from there
I cannot imagine git being a performance bottleneck in agentic workflow.
> You can work on many tasks in parallel without needing to download everything or fight worktrees.
What does "download everything" even mean? Why would you "fight worktrees"?
Yeah, I'll just wait for jj to get more virtualized FS features, and be very, very happy with that.
I love jj! Martin is really awesome and love his work. I know they're using a VFS backing inside Google for their monorepo, wonder if we'll get some of those cool features on the outside.
A few comments:
* The core idea sounds interesting. Make it the first paragraph, not paragraph seven.
* Spend more words describing what makes Oak different.
* "I built a version control system in my free-time called Jam". You probably didn't name your free time. "I built a version control system, called Jam, in my free time."
"I built a version control system, in my free-time, called Jam" is fine.
Just "I built a version control system called Jam". The free-time thing is good for a history page but the homepage needs to tell the important part (you've got history and expertise in this subject) and then move onto what the vision is for Oak and what kind of help you need.
It's also fine without the commas, because nobody was confused by that structure.
Lots of self-promotion, but no concrete comparisons where this tool does a better job than git.
The only thing to go on is this single sentence: "With virtual mounts, agents locally and in the cloud no longer need a full copy of a repo to get working."

I don't understand anyone who feels incentivized by this. Brogrammer 2.0 is weird.
Check out the homepage! https://oak.space might have what you're looking for. I can answer any questions you have here as well.
Since this project hasn't appeared on HN before and is obviously of interest to people, I've taken the liberty of turning your post into a Show HN (which is the convention for sharing your work on Hacker News - https://news.ycombinator.com/showhn.html). I used the text from your blog post that explains what the project actually is - this is the bit we need to lead with, to stanch all the "I can't tell what this is" comments.
I hope this is ok! If you prefer different text at the top, let us know at hn@ycombinator.com.
The blog post is a terrible intro, the website is much more insightful: https://oak.space/
I found the section titled “Local feature branches. Server main. One squash.” most interesting.
