1Code - Open source Cursor-like UI for Claude Code

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.

Hey Serafim, that line about the CLI feeling like a limitation once you’re running multiple agents makes sense. Was there a specific moment where you were juggling several Claude Codes and thought okay this workflow is fighting against me?

What’s next: Adding OpenCode, Codex, other models and coding agents.

Anthropic better acquire this company before everyone switches to 1Code and the Claude Code backend gets quietly replaced 😳

@topcatnocap 1Code is not for sale.

Yurii Rebryk

Finally, someone did it!

@rebryk appreciate it

9 products, 1 million users, $200k revenue... And I still can't figure out how to fix my Wi-Fi. :D But seriously, 1Code looks super amazing!

Jesse Craig

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

Marcos Sei

Congrats on the launch

Is this Claude Code Agent or its another agent that uses Agent SDK, Opus 4.5 with Claude Subscription?

Daniel Dhawan

Great app, love Claude Code, but this is just better for non technical people and even for me when I’m too distracted to open IDE.

Can you add preview?

Harsh Sahu

Parallel agents are the real speed unlock.
GTWY is built around the same idea: let AI operate concurrently, but predictably, inside real systems.

Abhijith Pingali

This is wild. I've tried probably 10 different AI coding tools and they all fall apart when you're working across multiple files or trying to understand existing codebases. The fact that this actually reads your whole project context and suggests changes that don't break everything else is exactly what's been missing.

One thing I'm curious about—does it handle refactoring well? Like if I want to rename a function that's used in 20 files, will it catch all the references or do I still need to double-check manually?

Also the $30/month unlimited is actually reasonable compared to Cursor/Copilot pricing. Gonna try this out.

Vansh Dixit

How do you usually decide what tasks to split across agents versus keeping in a single workflow?
