The collaboration layer for AI engineering teams
Edit, version, diff and roll back prompts from a visual dashboard with no coding, so product, marketing and content teams can iterate on prompts while engineers keep control of the deploy.
Run dataset-backed tests with human and AI graders, trigger regression evals whenever a prompt changes, backtest new versions against historical data and compare prompts across models.
Connect production traces to the exact prompt version that produced them and inspect failures, cost, latency and token usage by feature, model or user.
Build, trace and improve agent workflows with prompts, tool calls, evaluations and logs in one place, so multi-step runs can be tested before they ship.

Open-source control plane for orchestrating coding agents
Run Claude Code, Codex, Antigravity, OpenCode, Cursor and Grok sessions side by side in one workspace.
No resold tokens or quota caps — connect the credentials and plans you already pay for, and switch models mid-thread.
Manage branches, automate commits and pushes, and handle pull requests with inline diff review before accepting changes.
Open-source and MIT licensed, so you can run it on your own infrastructure and modify it for your team.
