Composer lets you work with Claude and Codex in one continuous project thread. Start a task with one agent, switch to the other when the work calls for it, and keep the context attached to the same real workspace.

What Composer helps with

  • Plan with one agent and review the plan with another.
  • Hand off implementation work without rebuilding context in a separate terminal.
  • Compare parallel first passes before choosing which thread to continue.
  • Keep the working directory, branch context, and conversation state together.

Project surfaces

Composer ships as a desktop app, a CLI, and a web landing page from this monorepo. The docs in this folder are intended to be deployed with Mintlify and served from the /docs path on the main website.
