About HarnessRouter Community Edition
HarnessRouter Community Edition provides an open-source agent harness infrastructure that allows integration of multiple AI agents such as Codex, Claude Code, and Hermes through a single API. It operates as a self-contained system with Gateway, Runner, and Console components bundled in one Docker container, eliminating the need for external databases or cloud accounts. The tool manages the full lifecycle of agent tasks including session creation, streaming responses, file handling, artifact generation, cancellation, and structured error handling. It uses the Unified Harness Protocol (UHP), an open and versioned HTTP contract, to ensure portability and interoperability between different agent implementations. Community Edition supports local deployment with user-controlled infrastructure, including provider keys, state storage via SQLite, and workspace files. The system includes a web-based console for managing harnesses, benchmarks, and examples, and offers starter kits demonstrating production-ready implementations for slides, spreadsheets, dashboards, and video editing.
