What is FastRouter.ai?
Route Faster. Scale Smarter. Build Better AI Apps.
FastRouter.ai is a unified LLM gateway that lets enterprise AI teams route, compare and operate across 200+ models through a single OpenAI-compatible API. Each request is automatically routed to the model with the best quality, cost and latency trade-off, so you stop paying for an expensive model when a cheaper one would do.
It adds the production layer around raw model APIs: project budgets, API-key limits, RBAC, rate limits and spend alerts, plus automatic retries and fallback models across providers for reliability. A unified dashboard tracks cost, latency and errors, with weekly billing-optimization insights.
Every plan passes model costs through at zero markup — you pay providers' token prices directly. The Starter tier is free forever, and Enterprise can self-host so prompts, logs and keys never leave your network.

Common questions
FastRouter.ai FAQs
Is there really zero markup on models?
Yes — all tiers pass through the underlying providers' token prices; plan fees cover the platform only.
How much do I save with annual billing?
Annual billing gives 2 months free, i.e. 16% off (Pro $1,990/yr, Business $7,990/yr).
Can I bring my own provider keys?
Yes — BYOK quotas per tier, e.g. Starter allows 1 key with 1M requests/month, scaling up on higher plans.
Can I self-host FastRouter?
Enterprise only — deploy in your own cloud account or data center so prompts, logs and keys stay in your network.
