Smarter LLM Rate Limiting & Quota Management

FastRouter helps teams control LLM usage before it turns into outages, throttling, or surprise bills. With project-level quotas, API-key limits, alerts, analytics, and governance across 100+ models, your applications can scale confidently while staying within budget. Manage high-volume AI traffic through one OpenAI-compatible control plane built for reliable production operations.

Our LLM Rate Limiting Services

Manage LLM traffic, quotas, alerts, access, and spend controls across providers from one unified gateway.

Quota Controls

Set project-level limits that keep applications, environments, and teams within approved usage boundaries while allowing developers to ship AI features safely through one centralized gateway.

API Key Limits

Apply API-key-level limits to contain runaway usage, reduce risk from leaked keys, and assign precise access boundaries for different services, customers, or internal teams.

Usage Analytics

Track token consumption, request volume, model usage, provider cost, and team-level spend in unified dashboards built for engineering and finance visibility.

Cost Alerts

Receive real-time notifications when usage, cost, latency, or error rates cross defined thresholds, helping teams act before budgets or user experiences are affected.

Access Governance

Control who can use which models with roles, access controls, compliance logging, and audit trails that support safer production AI operations.

Fallback Routing

Route around provider rate-limit errors and outages using fallback lists, virtual model aliases, automatic retries, and multi-provider redundancy for higher effective capacity.

Deploy Quotas in Four Steps

Connect Through One Unified Gateway

Start by connecting applications through FastRouter’s OpenAI-compatible API. This creates one gateway layer for traffic across providers, making it possible to enforce consistent quotas, access policies, observability, and routing without rewriting every application.

"FastRouter is a good value add, specifically when you are not sure which LLM is better for your use cases. You can play around with models, can compare against them, and then use normal OpenAI compatible APIs call to leverage the full potential of it."

Meet The FastRouter Team

A platform team focused on reliable production AI operations.

FastRouter is built around a clear vision: give teams one operational foundation for running LLMs reliably in production. Instead of managing separate provider accounts, fragmented dashboards, custom retry logic, and application-by-application quota rules, teams can govern AI traffic through a single OpenAI-compatible control plane. FastRouter unifies model routing, observability, experiment tracking, guardrails, cost governance, and evaluations across 100+ models. Its platform is designed for engineering leaders, platform teams, product teams, and finance partners who need AI systems that are scalable, accountable, and cost-aware. The result is a practical LLMOps layer that helps organizations move faster while maintaining control over usage, performance, reliability, and spend.

Frequently Asked Questions

What is LLM rate limiting and quota management?

LLM rate limiting controls how many requests, tokens, or workloads can be sent to models within a defined period. Quota management sets broader usage or spend boundaries by project, team, or API key. Together, they prevent runaway consumption, protect budgets, reduce provider throttling, and keep production AI applications operating within approved limits.
