1Code - Open source Cursor-like UI for Claude Code
by•
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.

This is a solid and timely contribution to the AI coding space. Running multiple Claude Code agents in parallel with both local and remote sandbox support is a strong productivity unlock, especially with live previews across devices. The open source approach also signals long term intent and trust. Insight wise, parallel agents change not just speed but how developers reason about progress and ownership across tasks. From a technical and onboarding perspective, how do you coordinate state, conflicts, and context sharing between parallel agents, and what signals do you surface to help new users understand which agent is doing what during their first sessions?

@igorkotua thanks!
That's crazy. I've just given in and bought Claude code today after an infuriating few days with Cursor. Feels like Cursor is dead unfortunately, it was a great run. Very excited to try this out, hope you're going to maintain and push this forward!
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.

Wow, 1Code looks incredible! The live preview feature for mobile apps while running agents is a game changer. How does the remote sandboxing handle file access for more complex projects?
