# OpenSEO

> Open-source, self-hosted SEO platform powered by DataForSEO API.

OpenSEO is an open-source alternative to expensive SEO suites like Semrush and Ahrefs. It allows users to self-host their SEO dashboard on Docker or Cloudflare Workers, paying only for the underlying DataForSEO API usage rather than fixed monthly tool subscriptions. It also features integrations and MCP support to connect SEO workflows directly into AI coding agents.
