Perturn is in closed beta

Perturn is open to a few teams at a time. You ask for a place on www.perturn.ai, a person reads every request, and we reply within two working days.

What you get

One key for every AI coding tool your team uses. Perturn routes each turn to the best-value model for the job, keeps spend inside the budget you set, and shows everyone why. Claude Code, Codex, Cursor, Aider, Cline, Continue, OpenCode, Kilo Code, omp and Hermes route through it today, and so does any tool that speaks the OpenAI API. Perturn's own coding agent comes with it, in a terminal, on the desktop, on your phone and in VS Code, on the same key.

Your provider accounts stay yours. Perturn carries your OpenRouter key, a direct provider key, or your Claude, Kimi and Copilot subscriptions, and charges nothing for model usage itself.

How to ask for a place

1. Open www.perturn.ai and press Join the beta.
2. Fill in your name, your work e-mail, your company, the size of the team and the coding tools you use today.
3. Press Request a place. The page thanks you, and we reply within two working days.

What happens when a place opens

We create your team, mail you a link to set your password, and you are routing turns the same afternoon. The beta runs as a 90-day trial. During it you have the whole dashboard: spend by person and group, the decision behind every turn, model rules, and the audit trail.

What we ask of you

Tell us what the dashboard got wrong, what a refusal should have said, and which model you would have picked. The support desk is in the dashboard, and a mail to hello@perturn.ai reaches a person.
