🚀 RouterFuel is in open beta. All features are free during preview.

RouterFuel is a single async proxy layer in front of every model provider you use — 330+ models via direct integration plus OpenRouter. Built on a Tokio and Axum network core, it multiplexes concurrent inference requests, negotiates provider failover in microseconds, and streams tokens back without adding measurable overhead.

// architecture

Every RouterFuel deployment ships with the same resiliency core — no add-on modules, no separate billing for the parts that keep your inference layer alive.

Vector-matches incoming prompts against prior completions and serves near-duplicates from cache, cutting repetitive API spend by up to 40%.

Trips automatically on provider error spikes or latency drift, rerouting in-flight and new requests to a healthy fallback provider with no dropped calls.

Inject headers, rewrite request bodies, and track upstream server health parameters with a middleware chain that runs inline with zero added round-trips.

Seamlessly route to any model OpenRouter supports. Automatic catalog sync means new models appear without code changes.

// licensing

RouterFuel's core is licensed under AGPL-3.0. That works great for self-hosting and open-source use, but if you're embedding RouterFuel in a closed-source product or run into AGPL's network-use clause at your company, we offer a separate commercial/enterprise license with no copyleft obligations.

Accounts launch after the open beta — join the waitlist to get notified the moment they're live.
