Bernstein coordinates several AI agents at once and keeps them under control. A deterministic Python scheduler runs agents in parallel without using a model in the coordination loop, so the same plan can be replayed exactly.
You write rules as code for approvals and records, and Bernstein enforces them and keeps a verifiable log of each run. It includes adapters for Claude Code, Codex, Gemini CLI, Aider and many other tools. It is open source under Apache 2.0 and can run on-premises.
