Hi, we're Sergey and Serafim. We've been building dev tools at 21st.dev and recently open-sourced 1Code (https://1code.dev), a local UI for Claude Code. Here's a video of the product: https://www.youtube.com/watch?v=Sgk9Z-nAjC0 Claude Code has been our go-to for 4 months. When Opus 4.5 dropped, parallel agents stopped needing so much babysitting. We started trusting it with more: building features end to end, adding tests, refactors. Stuff you'd normally hand off to a developer. We started running 3-4 at once. Then the CLI became annoying: too many terminals, hard to…

Hey Everyone, been working on a note-taking app called janta (Just Another Note Taking App) the past few months. You can try it out at app.janta.dev (you will be redirected to app.janta.dev/canvas/temporary, which is the locally-stored whiteboard you can access) I felt limited with OneNote, Excalidraw, and other infinite-canvas style apps, so I built an alternative.

Private developer tools for Mac, built for AI workflows

We wanted to run multiple AI coding assistants in parallel and swap models easily (Claude Code, local, Codex, etc.) without messing with the current branch. DevSwarm is a mac/windows desktop app that runs assistants on separate git branches so you can stay in the loop and compare/merge safely. Not an IDE, an Augmented Development Environment (ADE); open any branch in your IDE with a click. We’ve been dogfooding it for months, including DevSwarm. Try it in minutes: download, open a repo, start two assistants. Free beta.
