OpenSEO

Open source SEO platform with keyword, competitor and audit data

About OpenSEO

OpenSEO is an open source SEO platform positioned as a self-hostable alternative to expensive suites like Semrush and Ahrefs. Powered by DataForSEO data, it covers keyword research, competitor analysis, backlinks, rank tracking, technical audits and AI-search visibility, and exposes an MCP server so AI agents such as Claude and Codex can run SEO workflows directly. A hosted version is available for users who do not want to self-host.
