About HarnessRouter Community Edition

HarnessRouter Community Edition is an open-source, unified interface for agent harnesses designed for developers and AI infrastructure builders. Released under the Apache 2.0 license, it allows you to easily plug and play managed agent harnesses—such as Codex, Claude Code, and Hermes—into your products through a single API on your own infrastructure.

With HarnessRouter, you can seamlessly switch between different agent harnesses without having to rebuild your backend. The tool handles complex state operations out of the box, including sessions, streaming, files, artifacts, cancellation, and failure recovery. Furthermore, your model provider keys, state, and deliveries remain completely under your control, packed conveniently into a single Docker container containing the Gateway, Runner, and Console.
