HarnessRouter: one gateway to run Claude Code, Codex and other agents

An open-source gateway (Apache-2.0, about 3.4K GitHub stars, self-hostable with Docker) that puts 26 agent 'harnesses' behind one OpenAI-style API, so one agent can hand a task to another. The headline '99.8% lower cost, 3.2x faster' is the company's own benchmark, comparing its best and worst of 8 setups on a single task, and cloud plans run from $0 to $1,000 a month, per the company. The post shows no sponsorship disclosure and reads like a promo; see the demo under Worth testing.

Why it mattersMixing agents (one to analyse, one to build) without being tied to a single vendor is useful, but this is developer infrastructure, not a no-code tool.
