About LowRouter

LowRouter is made by Carbonifer, a French company based in Nantes, founded by Olivier Bierlaire and Yorly Orellanos.

We built it to answer a question we kept running into as engineers: what does this software actually cost the planet, for this specific request? AI is becoming one of the biggest energy sinks in software, and almost nobody puts a number on it.

LowRouter sits between your application and the AI providers. Your requests go through us, we pass them to the right model, and we report a few things nobody else does along the way.

Every response reports the energy the request used and the CO₂ it likely produced. These are estimates and labelled as such. How we calculate them is public, so you can check our math.

Most services sell you a brand name and hide who actually ran your request, and where. We name the provider and the region every time, and you can keep your traffic inside a jurisdiction you trust. We’re European ourselves: we sit outside the US CLOUD Act and inside GDPR and the AI Act, which many of our customers are required to meet.

We see every prompt and every answer, and we don’t mine them. They pass through and get counted.

We apply the same standard to ourselves: LowRouter runs on open-source technologies and mostly* European services, hosted at OVHcloud, in France.

* Mostly, because a few pieces aren’t European yet. Stripe handles our payments, for instance. They operate under European jurisdiction, and we plan to replace them with European alternatives as credible ones emerge.

LowRouter is a paid service. You buy credits and spend them on requests, and that revenue is what funds us, not your data. The pricing is public.

We’re in invite-only beta. The docs, the dashboard, and the way we measure carbon are all public, so you can check them before you sign up.
