    Commented on LowRouter · Nov 2, 2026

    Hi everyone, I'm Olivier, the developer behind LowRouter, based in Nantes, France. I wanted my agents to stay on EU-sovereign providers when the data calls for it and to prefer cleaner grids otherwise. I also wanted to know what each run emits, without juggling accounts across providers. You set one base URL and key in OpenCode, OpenClaw, your SDK or your framework, then pick a rule (EU-sovereign providers only, lowest carbon, lowest price) or a specific model. Every response tells you the provider, the region and a carbon estimate. Setup guides for the main agents and frameworks are in the docs. I'd love feedback, especially on the routing rules and the carbon numbers.
