HarnessRouter Community Edition is a self-hosted, Apache-2.0 unified interface for agent harnesses, exposing Codex, Claude Code, Hermes, PI, DSH and others through one API with sessions, streaming, files, cancellation, and failure handling. It implements the Unified Harness Protocol (UHP), an open standard, and runs on your own infrastructure with your own keys.

It lets you drive multiple agent harnesses through a single self-hosted API instead of integrating each one separately.

Use it to

  • Run multiple agent harnesses behind one unified API
  • Self-host agent infrastructure with your own API keys
  • Build against the Unified Harness Protocol (UHP) standard
  • Handle sessions, streaming, and cancellation uniformly across harnesses
  • Test harness implementations for UHP conformance

For Developers running or integrating multiple AI coding agent harnesses
