Private AI gateway
One gateway for image APIs, ComfyUI, and transcription.
HappyRouter gives your apps one stable API layer with failover upstreams, request metrics, per-key access, and token-bound R2 output storage.
Multi-upstream failover
Bind one public API to ComfyUI, Replicate, Workers AI, or your own services and let priority decide the route.
Health and request metrics
Track success rate, attempts, latency, alerts, and per-token usage without checking every upstream manually.
Output storage by token
Require each API key to bind an R2 profile so generated files land in the right bucket automatically.
Gateway runtime
A compact view of routing, health, and output ownership.
