About RouterFuel

RouterFuel is an async Rust LLM gateway routing to 330+ models (OpenAI, Anthropic, Google, Meta, Mistral, and every model on OpenRouter) with semantic caching and automatic failover. RouterFuel is a single async proxy layer in front of every model provider you use: direct integrations for 11 major labs, plus every model on OpenRouter as a fallback. Postgres + pgvector are provisioned automatically by Docker Compose. Every provider named is one RouterFuel actually routes to; nothing here is fabricated, it's just not connected to a real running instance on this page.

About Wattfare

Users connect, set a spending cap, and you call any model through one SDK, charged to them, not you. OpenAI-compatible Works with the Vercel AI SDK ~5-min integration. One button connects a user's inference budget to your app, metered, capped, and revocable. The problem AI costs are the one line item you can't predict. Every AI app makes the same uncomfortable bet: price high enough to survive your power users, ration usage so nobody hurts you, or quietly lose money on the heavy ones.
