About OpenRouter
OpenRouter is a hosted API gateway that gives you a single endpoint to reach over 200 LLMs from providers including OpenAI, Anthropic, Google, Meta, and Mistral, billed on one account.
Its edge is consolidation: usage-based billing is aggregated across every supported provider on one account, it supports bring-your-own-key so you can plug in existing provider keys, and its responses are OpenAI-compatible, making it a drop-in replacement for many existing integrations.
It fits teams that want to switch or compare models across vendors without wiring up each API separately or juggling multiple bills. It is less suitable if you need to self-host, since it is a managed hosted service, or if you expect the full catalog for free — the free tier only covers a subset of models — and it does add an intermediary routing layer between you and the upstream providers.
In its category it plays the aggregator role: instead of one vendor's models, it fronts many behind a single OpenAI-compatible interface.
