TL;DR
HarnessRouter Community Edition (Apache-2.0) lets you run agent harnesses like Codex, Claude Code, Hermes, PI and DSH on your own machine inside a single Docker container.
Key points
- One unified API with sessions, streaming, file handling, cancellation and failure handling across harnesses
- Implements the Unified Harness Protocol (UHP), an open standard shared with the hosted version
- Fully self-hosted: your keys, your data, no account, no cloud, no telemetry; 800+ stars on GitHub
A notable option for developers orchestrating multiple coding agents on their own infrastructure.
