CodeAlta is an open-source agentic development environment: AI coding agents, your code, terminals and Git in one workspace. Run your agents on your laptop, on your other machines, or across a whole team, on Windows, macOS and Linux.
- 🤖 Any agent, any model: Claude Code, Codex, GitHub Copilot, ACP agents, APIs or your own llama.cpp server.
- 🪟 One workspace: sessions in split panes, terminals, diffs, worktrees, reviews, issues and pull requests.
- ⚡ Automations: start sessions on a schedule, or on GitHub, Jira or Slack events.
- 🧩 Extensible: skills, MCP servers, plugins, canvases and hooks.
- 🔒 Yours: a sandbox for commands, statistics kept on your computer, and no telemetry.
Its agent harness holds its own: on hard tasks of SWE-bench Pro, it resolves as many tasks as Claude Code with Claude Opus, for 12% less.
Pair your machines, move a session mid-task, and bring your team together with a server that runs no agent and reads no conversation. Learn more →
