LLM Gateway

LLM Gateway is a web and API service for developers, teams, and enterprises that need a single interface to call and manage multiple LLM providers.

Key capabilities include:

• Unified, OpenAI-compatible API for integrating across 210+ models and 25+ providers (including OpenAI, Anthropic, and Google) with minimal code changes (often just updating the base URL).
• Dynamic routing that lets applications switch providers or models without rewriting integrations.
• Real-time analytics for requests, tokens, latency, and spend, including per-model and per-provider breakdowns to spot cost outliers.
• Controls and governance such as rate limiting (free tier includes 20 requests/min on free models) and optional audit logs and guardrails (prompt injection and PII detection) for higher-control environments.

Pricing: Freemium with a Free tier ($0 forever, no credit card) and an Enterprise plan with custom pricing, volume discounts, custom rate limits, and 24/7 SLA support.

Notable for combining an OpenAI-format drop-in migration path with cost and reliability monitoring across providers, plus the option to self-host (AGPLv3) or use the managed cloud service.
