Moo, Git versions code, moo versions machines
I'm Evan, CTO of Ito (ito.ai). We do code review that actually runs your code. When we're developing locally, we run lots of coding agents in parallel against the same repo, and we kept hitting the same wall: git worktrees isolate files, but the database, ports, and services all collide. Moo is a brand new internal tool we use to moove faster and thought we'd share it. Every branch or agent attempt gets its own isolated Linux machine, and the machine's state is versioned with your repo. Moo save snapshots the runtime tagged with the current commit. Check out an old SHA, run moo new, and you…

moo gives every git branch, worktree, or agent attempt its own hardware-isolated Linux machine — database, ports, packages, services and all — with the machine's state saved per commit and restored by git checkout . $ moo new feat/billing # a machine for this branch $ moo run feat/billing -- npm run migrate # migration applied inside it $ git commit -am "add billing migration" $ moo save feat/billing # runtime snapshot, tagged with the commit $ git checkout HEAD^ # rewind the code… $ moo new feat/billing # …and the machine follows. # the migration is gone; state matches code One noun (the machine ), four verbs ( new , run , save , drop ). Everything else composes from those four plus the…from github.com

ItoAug 2026 · ito.ai · ▲449I'm Evan and I made Ito.ai It's code review that actually runs your code. The result is that it finds more bugs with a smaller false positive rate. You get screenshots, videos, and run logs. I built Ito because manual verification sucks and I thought I could automate it. I've been a professional developer for 15 years and now more than ever, I'm just spending time making sure things work. I looked into all of the other agentic testing tools that click around a url you give them and frankly, they sucked. They just didn't work. I figured to be able to actually testing things you need to run…
- ICI created a cross-platform GUI for the JJ VCS (Git compatible)2025 · ▲140
Personally, I think the JJ VCS (https://github.com/jj-vcs/jj) hit a point some time in this past year where I find it hard to find a great reason to continue using git. Over the years I've cobbled together aliases and bash functions to try to improve my git workflow, but after using jj, which works with ~any git repo and integrates great with Github repos, all of the workflow issues I ran into with git are not only solved, but improved in ways I couldn't manage with simple scripts. One example is the op log, which lets you go to any point in your repo's time and provides…
Parallel CodeMar 2026 · parallelcode.app · ▲159I kept running into a structural problem with AI coding tools. You try one agent. It makes changes. You try another. Now you're manually diffing branches and cleaning up experimental commits. The tools are powerful, but the workflow isn’t designed for comparison. So I built Parallel Code. It runs Claude Code, Codex, and Gemini CLI natively (no API wrapper, no feature abstraction), but isolates each agent in: its own terminal its own Git worktree its own feature branch The workflow becomes: Spawn N worktrees Assign one AI agent per worktree Let them implement independently Compare diffs Merge…
Keep – GitHub Actions for your monitoring tools2023 · github.com · ▲181Hi Hacker News! Shahar and Tal from Keep here. A few months ago, we introduced here at HN (https://news.ycombinator.com/item?id=34806482) Keep as an “open source alerting CLI” and got some interesting feedback - mainly around UI, automation, and supporting more tools. We were VERY early back then, and we understood that although the current DX around creating alerts is not great, it's not that critical and developers don’t need another tool just for that. But we did find something else. While talking to developers and devops, we found that a lot of companies use many tools…
Mozzie Mar 2026 · github.com · ▲80Mozzie started as a tool I built for my own workflow. I like working on multiple things at once, but most development tools split the workflow across different places: tickets live in issue trackers, execution happens in terminals, and context gets lost between them. I wanted my work items and their context right next to the place where the work actually happens. Mozzie is a local desktop workspace where each work item can spawn its own terminal or coding agent. The idea is that tasks become the primary interface — each one holds its context and can run commands or agents independently. This…

I might be the only SRE on Earth with his own bowling center. It's a more in-depth gig than you'd think. My family and I bought an abandoned 8-lane bowling center in the rural mid-west. In our small town there weren't many recreation options for families. You've heard of a food desert? This is an R&R desert. It had been abandoned for a good reason. The roof leaks, the electrical system was constantly surging, and my 70-year-old bowling equipment (still) doesn't work perfectly. The system that keeps your score is particularly interesting to me. It's the thing you watch during your game, but…

Over the past few months, our team has been building more and more slidedecks using web frontend technologies with coding harnesses like Claude Code, but a common complaint is to make even small edits we need to edit the code either manually or via the harness. To avoid this loop, I ended up creating Bento, a single HTML file with everything you need in a slide tool including animations and shared editing. There's no install or cloud login, everything works offline. The default deck is around 560 KB and it doesn't need to fetch anything once you got it. Open it in a browser and then you can…

A few days ago I found myself trying out GLM 5.2 and was really positively impressed. The capabilities and security I was getting from this LLM are similar to those I've gotten from models like Claude or GPT, and this really surprised me. But then I thought, "I wonder how it would work on a normal computer like mine," and above all, "I wonder if it would work without going into OOM on a computer like mine." So I started working with the help of agents to test this possibility. I started converting the model to int4, understanding MTP usage, and if possible implementing DSA for long context.…

OpenSEO▲928Hello! For the last 2 months, I've been building OpenSEO. It's a user friendly UI wrapping the DataForSEO API which has high quality SEO data for keywords, backlinks, AI SEO and competitor research. Instead of paying $100+ per month, you buy DataForSEO credits and pay only for usage. The coolest thing about the project so far has been hearing about what people are building on top of it. People are using coding agents to quickly integrate with Google Search Console, Google Ads and building their own AI SEO and reporting features. Many were already building their own custom solutions around…
