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

Router is an LLM gateway built to reduce inference costs by matching each request to the lowest-cost model that still meets performance needs. It provides one endpoint and one API key for accessing multiple closed and open-source AI models from providers such as OpenAI, Anthropic, Grok, Fireworks, and others, helping developers avoid wiring applications to providers one at a time. Requests go through Router first, where usage, model, provider, and cost can be tracked before eligible workloads are routed to a more efficient option when quality will not be affected. Router Strategies let developers define cost and performance priorities for different types of requests or use benchmarked defaults based on real production workloads. It responds to live latency, availability, failures, and rate limits, and eligible requests can be moved to another available model when a provider cannot serve them.
