LLM Gateway
LLM Gateway is an API layer for working with multiple LLM providers through one integration. It is described as a single API for 40+ providers, including OpenAI, Anthropic, and Google, and it routes requests across 200+ models while tracking costs in real time. The service is also presented as a way to avoid juggling provider API keys and dashboards, and to switch providers without changing application code.
Several functions are called out on the product page. It offers a unified API interface that stays compatible with an existing OpenAI SDK setup by changing the base URL. It includes multi-provider support, performance monitoring to compare latency, cost, and quality, secure key management, cost-aware analytics, per-model and per-provider usage breakdowns, error and reliability monitoring, a project-level usage explorer, enterprise audit logs, and guardrails intended to prevent prompt injection, detect PII, and block malicious requests. The page also says requests are automatically routed to healthy providers in real time, with failover if one provider goes down.
The product is shown as working with OpenAI, Anthropic, and Vercel AI SDKs, and the page says it works with any language or framework. It is offered as a cloud service or as a self-hosted deployment on the user’s own infrastructure. Pricing includes bring-your-own-keys use at no cost, pay-as-you-go credits with a 5% flat fee on top-ups, and a free self-hosted option. The self-hosted gateway is licensed under AGPLv3. The page also mentions an enterprise offering with SSO, managed or self-hosted deployment, volume pricing, and white-label options. LLM Gateway is presented as a tool for developers and teams building and operating LLM-based applications.
