RouterBase routes 200+ AI models from OpenAI, Anthropic, Google, Meta and more through one OpenAI-compatible API — with smart routing, automatic fallback, and unified billing. Integrate once, switch models freely.
RouterBase started from a simple frustration: building with AI meant juggling a separate SDK, API key, and invoice for every provider — and rewriting code every time we wanted to try a different model.
So we built a single OpenAI-compatible gateway. Point your app at one endpoint and reach 200+ models from OpenAI, Anthropic, Google, Meta and others, with smart routing, automatic fallback when a provider goes down, and unified billing.
Integrate once, switch models freely, and never get locked into a single provider.
