Keep application code stable
Use one request shape and one endpoint while Everstack handles provider translation, routing, fallback, caching, tenant limits, and credentials.
Open-source AI infrastructure
One model endpoint. Every routing decision under your control.
Route AI traffic across providers with one OpenAI-compatible API, configurable fallback, semantic caching, rate limits, tenant isolation, and OpenTelemetry traces.
Carry policy through every request
Connect model selection, cache scope, rate limits, token use, cost, latency, and fallback behavior in the same request trace.
