1Code
Claude Code and Codex in one app. Switch agents, take the best of each.
1Code is an open-source, Cursor-like client for running Claude Code and Codex agents in parallel, built by the 21st.dev team. Each chat session runs in its own isolated git worktree, with diff previews, a built-in git client, a kanban board of agent sessions, live browser previews, and a message queue. Agents can also run as background agents in cloud sandboxes that keep working when your laptop sleeps, monitorable from your phone via PWA. Available as a macOS desktop app and a web app, with Windows and Linux support.
