About

LowRouter is a European AI gateway for agents and apps, providing one API key and one bill in euros for language models from European and international providers. Set routing rules per API key, including EU-sovereign providers only, lower-carbon routing, lower-cost routing, or a combination. Responses report the provider and region, with an estimated carbon figure when model data supports it. Coding agents such as OpenCode, Claude Code, and Cline can use LowRouter as a custom provider. Apps built with LangChain or the OpenAI SDK can also connect. Aliases let you switch models or providers without changing code, and automatic routing can send eligible requests to another provider when a route fails. The public model catalogue can be searched by sovereignty and carbon intensity. Tokens are billed at provider prices without a per-token markup; credit top-ups carry a fee, and there is no subscription. LowRouter is operated by Carbonifer SAS in Nantes, France.

About

flo2 is an LLM gateway and router that provides access to major AI model providers (OpenAI, Anthropic, Groq, Cerebras, DeepInfra) through one unified, OpenAI-compatible API. Smart routing picks the cheapest or fastest model per request. Automatic fallback keeps applications running when a provider goes down. Racing mode runs requests across providers in parallel. Full cost accounting per request, per model, per project. Developers use their own provider keys via flo2.com — RapidAPI's testing tier includes free tokens for evaluation.
