OpenRouter
One endpoint in front of many model providers
- Paid
- Model Providers
What it is
OpenRouter is a routing layer that exposes models from many vendors behind a single OpenAI-compatible endpoint, with unified billing and per-request routing rules. Provider fall-back means a request can survive one upstream being unavailable, and requests can be pinned to a specific provider when determinism matters. Switching models becomes a string change rather than an integration project.
Best for
Comparing or hot-swapping models across vendors without maintaining a separate integration for each one.
Where it falls short
It adds a hop to every request and abstracts away provider-specific features, which matters once you depend on one vendor’s edge capabilities.
