App

Point ready-to-run agent apps and chat gateways at FastRouter. Install once, run a setup command, get 100+ models with full cost visibility.

These are standalone apps and gateways you run as-is, no framework code to write. Most install a FastRouter setup skill, then wire themselves up from a single natural-language command with your API key. Once connected, every request routes through FastRouter with:

  • 100+ models from OpenAI, Anthropic, Google, xAI, Meta, Groq, and Mistral behind one key. Switch models from the app's own picker.

  • Observability on every request: cost, tokens, latency, and model per call, visible in your dashboard.

  • Reliability through automatic failover across providers, response caching, and intelligent routing.

  • Governance with per-key budgets, rate limits, model restrictions, role-based access, and project isolation.
