What is CrbonFree?
CrbonFree is a carbon and energy metering platform that measures the energy use and CO₂e emissions of AI workloads per token, per model, and per provider. It targets engineering teams who need defensible AI carbon accounting, connecting to major AI providers (OpenAI, Anthropic, OpenRouter, AWS Bedrock, etc.) via read-only keys, SDKs, MCP server, CLI, or browser extension.
