Every agent gets its own copy of production.

Branches are copy-on-write and ready in seconds, on the Postgres you already run. Sensitive columns are masked on the way in, so agents never see the real values.See what comes back →

Built for the stack you already have.

Any Postgres

Supabase and Neon first, on top of their branch APIs. Then RDS, Cloud SQL and self-hosted, with a clone engine inside your own account. Data never leaves your VPC.

Any agent

MCP-native. Claude Code, Cursor, Codex, Gemini CLI, or your own framework: one config line, and the agent branches before every task and opens a pull request when it is done.

We are onboarding a small number of teams on Supabase and Neon whose agents already touch production data. Leave your work email and we will set you up.
