HarnessRouter
One API for bringing AI agents into your product
HarnessRouter is a unified open source interface for integrating AI agents into products through a single API. It connects tools such as Codex, Claude Code, and Hermes without requiring separate backends for each agent. The platform handles tasks, sessions, streaming, files, and artifacts through a consistent interface, helping product teams add agent-powered capabilities and scale their applications without building and maintaining the underlying agent infrastructure.
