Harnessrouter

HarnessRouter is a unified interface for agent harnesses. Instead of building and operating agent infrastructure yourself, you plug Codex, Claude Code, Hermes, a DeepSeek harness and others into your product as agent runtimes through one API with a single request contract. The service handles the sandbox, session, recovery, streaming, artifacts, latency and cost tracking, and lets you run and trace each task from one console. It is aimed at teams building agent powered products who want to choose the model and harness, add skills, instructions and tools, and deploy, or migrate an existing managed agent backend. The vendor publishes a catalog of supported harnesses, a benchmark comparing the same task across harness configurations, and public harness rankings. A Community Edition is open source under Apache 2.0, implements the Unified Harness Protocol and can be self hosted with your own keys, state and files. HarnessRouter Cloud pricing is usage based, and waiting time is free. Plans are Free at $0 per month, Developer at $20, Production at $200, Scale at $1,000, and Enterprise on custom terms. Paid plans include their full price as usage, and top up rates are 30, 50 and 70 percent lower on the three paid tiers. Agent work is billed per active minute, from $0.020 on the Free plan down to $0.006 on Scale. Models are billed at catalog price with no markup, or you can bring your own keys.
