(open full size in a new tab)Our take: HarnessRouter suits developers who want to put Codex, Claude Code or Hermes behind one API in their own product and pay only for active agent-work minutes plus model usage at catalog price.
Main limitation: Free plan allows 30 agent-work minutes and 2 concurrent tasks, tracing is included only with Scale in beta, and agent memory is billed separately.

Not stated
HarnessRouter provides a unified API and console for running agent harnesses such as Codex, Claude Code, Hermes, DeepSeek Harness and Qwen Code as backends for your product. Each task runs in an isolated sandbox that HarnessRouter provisions and operates, with streaming, session continuation, file artifacts and recovery handled by the platform. The open-source Community Edition (Apache 2.0) implements the same Unified Harness Protocol for self-hosting. The Cloud offering bills model usage at catalog price with no markup, or lets you bring your own provider keys, and charges only for active agent work minutes; a Harness Arena compares time, cost and accuracy across harness and model combinations.
