What is 1Code?

1Code is a visual desktop and web client that lets you run Claude Code and Codex agents in parallel. Built for developers who want to ship faster, it replaces terminal-based workflows with a calm, keyboard-first interface. On macOS, agents run locally with optional Git worktree isolation. On the web, they run in remote sandboxes with live browser previews — so you can check on your agents from anywhere, even your phone.

Who it's for

• Solo builders — who want to run multiple coding agents side-by-side without juggling terminal tabs or losing context.
• Small teams shipping fast — that need background agents, live previews, and built-in Git workflows to review and merge without leaving the app.
• Developers who switch between models — who want one app to instantly swap between Claude Code and Codex, using the best agent for each task.

Key features

Parallel agents

Run multiple agents at once, each in its own session with full context. Work on several features simultaneously without conflicts or context loss.

Background agents that never sleep

Close your laptop — agents keep running in isolated cloud sandboxes. Live browser previews let you see your dev branch in desktop or mobile viewports from anywhere.

Built-in Git integration

Stage, commit, diff, and open PRs directly from the UI. Git worktree isolation keeps every agent session clean, so there are no conflicts or stashing.

MCP protocol support

Connect any MCP-compatible server — Notion, Linear, GitHub, Slack, Sentry, PostgreSQL, and more. Tag @1code in GitHub, Linear, or Slack to trigger an agent on demand.

What stands out

One app to run Claude Code and Codex in parallel — with background agents that keep shipping while you sleep.

That combination is rare. Most coding agent tools lock you into one model or force you to stay at your desk. 1Code gives you both major agents, lets you run them simultaneously, and keeps them working even when your laptop is closed. The live browser previews and mobile PWA access mean you can monitor progress from anywhere.

Worth checking out if…

You're a developer who wants to run multiple coding agents in parallel, switch between Claude Code and Codex on the fly, and have agents keep working in the background. It's especially useful if you want a visual Git workflow, live previews of dev branches, and the ability to trigger agents from GitHub, Linear, or Slack. The open-source tier is free to self-host, and the Pro plan starts at $20/month for background agents and web access.
