About open-seo
OpenSEO is an open source alternative to Semrush and Ahrefs that you control on a pay as you go basis. It provides focused SEO workflows through a modern simple UI. It exposes an MCP server and reusable agent skills so agents such as Claude Code, OpenClaw and Hermes can use SEO data directly. A hosted version is available at openseo.so, with Docker documented for personal use and Cloudflare documented for use across devices or with a team. Use requires a DataForSEO API key paid directly when self hosting. It suits people who find Semrush or Ahrefs too expensive or bloated and want a tool they control.
