What it is

OpenSEO is a web app for finding keywords, tracking search rankings, studying competitors, analyzing backlinks, auditing sites, and checking AI visibility, all paid per use through your own DataForSEO API key. It also exposes an MCP server and ships agent skills so tools like Claude Code or ChatGPT can query your SEO data. Marketers and small site owners who find subscription SEO suites too costly can run it with Docker or on Cloudflare, or use the hosted version.
