Our verdict on GatewayforAI

GatewayforAI is an open-source LLM gateway for developers who want one OpenAI-compatible endpoint while supplying their own provider API keys. It supports OpenAI, Anthropic, Gemini, Groq, Mistral, Together, DeepSeek and OpenRouter, with Anthropic SDK compatibility for clients built around that interface. The product is aimed at solo developers and small teams that need a straightforward routing layer rather than a large operational platform.

The published plan is a free hosted gateway service with no signup required; users pay model providers directly. The same project can be self-hosted through Vercel and Upstash Redis, giving teams a deployment choice between the hosted instance and their own environment. Its ecosystem fit is defined by the eight listed provider integrations and a common OpenAI-compatible endpoint, which can simplify applications that need to switch models or vendors without changing their primary client interface.

GatewayforAI’s strongest technical features are automatic provider fallback for errors and timeouts, configurable per-key sliding-window rate limits, encrypted provider-key storage, and streaming support that includes Anthropic-to-OpenAI chunk translation. Aggregate request counters provide usage visibility while prompts and responses are not persisted, according to the product description. The hosted offer is intentionally narrow: there is one free instance plan, and the stated company-size fit centers on solo and small deployments. Developers who want a lightweight BYOK gateway should find the feature set aligned with that use case; organizations seeking broader provider coverage or a more enterprise-oriented operating model should evaluate alternatives.
