HarnessRouter Charts #6 Selling 'The World's Best AI Agents Through One API' — The Router Pattern Moves Up a Layer From Models to Agents

Product Hunt·low signal

HarnessRouter launched July 24 with 252 votes on the promise of bringing multiple third-party agents into an app behind a single API. OpenRouter established this pattern for models; HarnessRouter is applying it one abstraction higher, betting that app developers will want to swap whole agents the way they currently swap model endpoints. Whether that holds depends on something models had and agents mostly do not — a stable, interchangeable interface contract — so treat this as a bet on the shape of the market rather than evidence of it.
