HarnessRouter is infrastructure for teams that want to ship agent features without engineering their own agent harness. Through a single API you can use existing harnesses, including Codex, Claude Code, Hermes and DeepSeek Harness, as the engine behind your product.
The pitch is saving build time and running costs by reusing proven agent backends instead of maintaining your own. It suits developers starting a new agent product or moving an existing one onto a managed layer. A demo can be booked from the site.
