This page is designed to help you find out whether LowRouter is good and if it is the right choice for you.
LowRouter is a European AI gateway that lets your agents choose where their requests go and shows what each one emits. Each API key follows the rules you set: EU-sovereign providers only, the cleanest electricity grid, the lowest price, or a mix. Every response includes an estimate of its carbon emissions, along with the provider and region that served it.
Point OpenCode, OpenClaw, Claude Code, Cline or Goose at it, or call it from an agent you wrote with the OpenAI SDK, LangChain, CrewAI, the Vercel AI SDK or n8n. You get one key and one bill in euros for language models from many providers, European and international. Aliases let you switch model or provider without changing code or config. In automatic mode, a failed request moves to another provider, so a long run doesn't stop because one provider is down.
Give each agent its own key to see what it spends and emits, and revoke that key without touching the others. The model catalogue is public and free to search by sovereignty and carbon intensity. Tokens are billed at the providers' own prices with no per-token markup; a fee applies when you buy credits, and there is no subscription.

AI Gateway and provider routing

Like any AI gateway, it gives you one API key and one bill for models from many providers, lets you switch models without rewriting code, and falls back to another provider when one fails. What LowRouter adds is control over where requests go and what they emit. A key can be limited to EU-sovereign providers, or set to prefer the cleanest electricity grid or the lowest price. Every response says which provider and region served it, with an estimate of its carbon emissions.
If you work in Europe, it’s simpler to pay in euros. You get one EU VAT invoice for every provider you use, with no currency conversion. Tokens are billed at the providers’ own prices with no per-token markup, a fee applies when you buy credits, and there’s no subscription. Choose it as well if you need some traffic to stay with EU providers, or want to report the carbon footprint of your AI use.
Developers and small teams who run AI agents and want one key and one bill for many models. Some use coding agents like OpenCode, Claude Code or Cline, and others build their own. Many are in Europe and need some or all of their traffic to stay with EU providers.
I’m Olivier, a software engineer in Nantes. I’ve given talks on the carbon footprint of software and AI for a few years, and in 2023 I started Carbonifer to work on cloud carbon and cost. With coding agents, I wanted to switch between models from different providers, keep sensitive work with European ones, and see what each run emitted. I couldn’t find a gateway that did all three, so I built LowRouter.
Go for the API and router, PostgreSQL for the ledger, React for the dashboard and Astro for the docs. It runs on Kubernetes on OVHcloud in France, deployed with Helm and Terraform. Carbon estimates combine Ember grid data, regional grid operators’ data and the EcoLogits energy model.
We have collected here some useful links to help you find out if LowRouter is good.
Check the traffic stats of LowRouter on SimilarWeb. The key metrics to look for are: monthly visits, average visit duration, pages per visit, and traffic by country. Moreoever, check the traffic sources. For example "Direct" traffic is a good sign.
