Automatic fallback keeps a provider hiccup from becoming downtime.
One stable endpoint — provider and model changes stay behind it.
See what's happening at the gateway before debugging turns into guesswork.
Issue keys and boundaries that fit environments, teams, and services.
See which routes, providers, and apps actually drive traffic.

Operational outputs
Gateway governance
Ownership, policy, and visibility — centralized by design.
When gateway configuration lives in the gateway — not in application code — it stays auditable, changeable, and owned.
Audit-ready history
Every request through the gateway carries provider, route, key owner, and outcome. Export logs for compliance records without building a separate pipeline.
Policy boundaries
Define which models, providers, and routes each key can reach. Policy lives at the gateway layer — not scattered across application codebases.
Fallback discipline
Chain fallbacks at the gateway so provider outages and rate limits are absorbed before reaching application code. No application-level retry logic needed.
Ownership clarity
Every key has a named owner and scope. Usage and spend are always traceable to a team, service, or environment — no orphaned traffic.
