A frontier coding agent that runs alongside Claude Code, Codex, and Cursor
Run Claude Code, Codex, Cursor, and Reason agents on the same repository without conflicts, so each tool handles what it does best.
Start an agent session from a script, CI job, or your own product, then poll or stream the result through a REST endpoint.
Give each Reason agent a name and team, and watch it work in a shared workspace alongside your human teammates.
Mention Reason in a Slack thread and get back a pull request, presentation, or answer once the task is finished.

A multitasking macOS terminal and agent manager for orchestrating AI coding agents
Run several CLI agents in one project simultaneously, each isolated in its own git worktree and branch so sessions never collide.
Anoint an orchestrator that genuinely monitors workers and reads their terminals, or convene a roundtable of role-played agents in a shared chat via crystl quest.
Turns, tool calls, results and tables are captured as agent-readable metadata and rendered fast on the GPU with Metal.
Approval requests, questions and alerts appear as color-coded glass cards, while a panel tracks token burn and estimates turns left.
