What is this?
An open source alternative to Semrush and Ahrefs: an all-in-one SEO tool you can use yourself or plug into an AI agent, paying as you go instead of a big subscription.

There is a hosted web UI at openseo.so, plus an MCP server so agents like Claude Code, OpenClaw and Hermes can use your SEO data directly. You can also self-host the whole thing.

Docker is best for testing or personal use on your own machine.

The hosted version is free to try, then $10/month — it is funded by a 28% surcharge on every DataForSEO request.

OpenSEO bets on focused workflows, no subscriptions, your own DataForSEO key, and a codebase you can fork and vibe code into your own custom tool.
