Open source Cursor-like UI for Claude Code
873 followers
Whats 1Code? An app to run your Claude Code agents in parallel that works on Mac and Web. On Mac - run locally, with or without worktrees. On Web - run in remote sandboxes with live previews of your app, mobile included, so you can check on agents from anywhere. Running multiple Claude Codes in parallel dramatically sped up how we build features.
Running multiple Claude Code agents in parallel is a massive unlock for velocity compared to serial chats. How does the system handle conflict resolution if two agents try to edit the same file structure simultaneously?
Is this gonna have problems with the new Claude Code Terms of Service?

@francisco_lopez2 1Code uses the official Claude Code SDK which wraps the Claude Code binary. This is the official way to build on top of Claude Code.
Some other tools (like OpenCode) made direct API calls while impersonating Claude Code - that approach got banned. We're not doing that.
Huge congrats on the launch! Love the focused, parallel Claude Code workflow for serious shipping.

@michael_vavilov people who want to utilize Claude Codes more efficiently
This is genuinely interesting. I like the idea of giving Claude a Cursor-like workflow instead of forcing people to jump between chat and editor mental modes. It feels especially useful for non-expert developers or managers who want to reason about code without fully living in an IDE all day.
That said, I’m curious how you’re thinking about long-term context and scale. Cursor shines when projects grow and files sprawl. How does 1Code handle larger codebases, cross-file reasoning, and keeping the AI grounded over time?
Overall, this feels like a smart direction, and I’d love to hear how you see it evolving beyond a nicer UI into something teams actually rely on daily. Great work so far 👏

Finally something to not be scared of worktrees

@igorkotua thanks!
The parallel agent problem so real. Curious how you're handling conflict resolution when agents touch the same files?
