LLM Gateway
Access 100+ AI models through one OpenAI-compatible API, eliminating separate provider integrations while centralizing routing, governance, observability, and billing for production AI applications.
FastRouter gives teams a production-ready LLM gateway for building reliable AI applications without brittle provider-specific integrations. Route requests across 100+ models through one OpenAI-compatible API, add automatic failover, monitor latency and cost, enforce guardrails, and govern usage from a single control plane built for real-world scale.
Operate production AI reliably with routing, failover, observability, governance, guardrails, and unified model access.
Access 100+ AI models through one OpenAI-compatible API, eliminating separate provider integrations while centralizing routing, governance, observability, and billing for production AI applications.
Automatically route each request to the best available model based on cost, latency, quality, or throughput priorities without hard-coding model choices across your apps.
Keep applications running through provider outages, rate limits, and model failures with fallback lists, automatic retries, multi-provider redundancy, and higher effective capacity.
Monitor latency, error rates, usage, cost, and request-level activity across every model and provider from unified dashboards and searchable logs.
Set spend limits, manage roles, apply access controls, and prevent surprise bill spikes with governance enforced consistently at the gateway layer.
Validate inputs and outputs across providers to enforce safety, compliance, structured response quality, and brand protection before content reaches users.
FastRouter replaces fragile, provider-specific AI infrastructure with one production control plane. Your team can route requests intelligently, fail over during outages, compare model performance, enforce guardrails, and understand spend without changing application code for every provider. The result is a more reliable AI stack that scales across products, teams, and model generations.
See how production teams reduce provider risk, control spend, and improve AI reliability.
"Excellent platform to test the latest LLMs for our use case. With new LLMs coming out every few weeks and benchmarks not giving the full picture, I rely on Fastrouter.ai to optimize my cost vs quality balance."
FastRouter helps teams operate AI apps with reliability, control, and measurable performance.
Route across 100+ models from major providers through one OpenAI-compatible endpoint.
Automatic failover and redundancy help protect users from provider outages and rate limits.
Dashboards, logs, alerts, and analytics make every AI request easier to understand.
Project limits, roles, guardrails, and billing controls keep AI usage accountable.
A platform built for production AI operations.
FastRouter is designed for teams that need more than basic model access. As AI applications move from prototype to production, engineering leaders face provider outages, rate limits, cost spikes, model drift, fragmented billing, and inconsistent observability. FastRouter brings these operational concerns into one OpenAI-compatible control plane, helping teams standardize how they route, monitor, govern, and improve AI workloads. Its vision is to make production LLM operations dependable, measurable, and adaptable as model providers evolve. By combining routing, failover, evaluations, guardrails, usage analytics, and cost controls, FastRouter gives product, platform, and ML teams the foundation to ship AI features with greater confidence.
A production LLM gateway is a control layer between your application and multiple AI model providers. Instead of integrating separately with OpenAI, Anthropic, Google Gemini, xAI Grok, and others, your app sends requests to one gateway. FastRouter then handles model routing, failover, observability, guardrails, spend limits, logging, and governance consistently across every provider.
