Bito (Governor)
Codebase-aware model router for coding agents
Bito's Governor is a router that grounds each coding-agent request in your codebase and sends it to a right-sized model. It combines a code context engine with a complexity-scoring model router. It works with Claude Code, Cursor, Codex and GitHub Copilot through a base-URL change, and supports per-key budgets. Bito also offers a system-aware AI PR review agent.
