CrbonFree

What it does

How much energy and carbon does your AI use? CrbonFree meters every call, per model and per provider, and turns the answer into a report an auditor can check.

Most teams guess their AI carbon footprint from cloud spend. CrbonFree meters every call, per model and per provider, with published factors and an uncertainty band you can defend. Start with the provider you use most. Connect it with a read-only key, an SDK, the MCP server, the CLI or the browser extension, and the first tokens land in seconds. Dashboard, SDKs, MCP, CLI and API share one contract, so a token counted anywhere lands in the same report. One view of tokens, cost and carbon across your providers, projects and coding agents, with CSV and JSON export. A typed client for your usage, emissions, receipts and audit packs from Node.js or TypeScript. Sync and async clients for your…from crbonfree.com

Otherwise you're a bank for your customers, and you'll run out of money before they do. Why invoice-based billing doesn't work for AI: Most usage-based billing tools (Stripe Billing, Orb, etc.) were built for SaaS. They meter usage all month, then send an invoice. That works fine when your COGS is 5%. It's a disaster when you're paying your AI vendor upfront for every request and your…
