Yep, I’ve needed something like this a few times. Even when trying to be careful to commit every step to a feature branch, I’ve still found myself asking for code fixes or updates in a single iteration and kicking myself when I didn’t just commit the damn thing. This will be a nice safety net.

Thank you! That's great to hear.
I spent a bit of time being baffled nothing existed that does this. Then I realized that, until Agents, the velocity of changes wasn't as quick and errors were rare(er)

Thank you for pointing out a problem that I had (which I do!), solving with Time Machine and trying to make myself commit more requently - and for providing a solution! Looks very cool, too. If I close the terminal I started --watch in, will the watch continue?
Writing this, I wanted to ask if the desktop app includes the CLI, but there it says it on your website :-) Thanks for thinking ahead so far, but then picking us up here and now so we can easily follow along into an unf* future!
Looking forward to try it.

yes, it worked a lot so once you say watch it watches until you stop it, including through closing terminals, computer power off, etc. It should restart on reboot, but -- test it yourself and tell me if I'm wrong :)
> unf watch
# reboot
> unf list
it should say watching on your directory still, if it stays crashed or something else. ping me at support at v1.co

This is so cool to have made yourself. How would you compare this to the functionality offered by jujutsu? I love the histogram, it was the first sort of thing I wanted out of jujutsu that its UI doesn't make very easy. But with jj the filesystem tracking is built in, which is a huge advantage.

I'm not a user, but I looked at the site and it looks like jj snapshots when you run a jj command. UNF snapshots continuously.
If an AI agent rewrites 30 files and you haven't touched jj yet, jj has the before-state but none of the intermediate states. UNF* captured every save as it happened, at filesystem level.
jj is a VCS. UNF is a safety net that sits below your VCS.
- UNF* works alongside git, jj, or no VCS at all
- No workflow change. You don't adopt a new tool, it just runs in the background
- Works on files outside any repo (configs, scratch dirs, notes) as it doesn't require git.
They're complementary, not competing.
W.r.t. to the histogram, this is my fav feature of the app as well. Session segmentation (still definitely not perfect) creates selectable regions to make it easier, too. The algo is in the CLI as well for the Agent recap (rebuilding context) features.

this seems insanely useful and well thought out. kinda surprised something like it doesn’t already exist. def useful in the age of agents

Appreciate that perspective and assumed some folks would feel that way.
I am more interested in testing if folks have the problem and like the shape of the solution, before I try to decide on the model to sustain it. Open Source to me is saying -- "hey do you all want to help me build this?"
I'm not even at the point of knowing if it should exist, so why start asking people to help without that validation.
I work(ed) with OSS projects that have terrible times sustaining themselves and don't default to it bc of that trauma.
Thanks for stopping by.

Well, some kind of transparency would be good indeed. Open source doesn't mean open contribution.

I'm happy to clean up the source for sharing. I didn't prioritize that for this HN Show but if folks like it, use it, and want to review for whatever reason including security audits -- happy to share.

why did you make it so complicated? magit has a `magit-wip-mode` that just silently creates refs in git intermittently so you can just use the reflog to get things back.
cyrusradfar 1 hours ago [-]
This was designed for any file save.
From what I know (correct me) magit-wip-mode hooks into editor saves. UNF hooks into the filesystem.
magit-wip-mode is great if your only risk is your own edits in Emacs. UNF* exists because that's no longer the only risk; agents are rewriting codebases/docs and they don't use Emacs.
