What is it?

OpenSEO is an open source alternative to Semrush and Ahrefs, aimed at people who find those subscription suites too expensive or complex. It covers keyword research, rank tracking, competitor insights, backlink analysis, site audits and AI visibility through a focused, simple interface.

The project is pay-as-you-go rather than subscription-based. Users bring their own DataForSEO API key to supply the SEO data and pay DataForSEO directly when self-hosting. Self-hosting is offered through Docker for local testing and Cloudflare for multi-device or team use.

OpenSEO exposes an MCP server so agents such as Claude Code, Codex, ChatGPT and OpenClaw can query SEO data directly. It also ships reusable Agent Skills that guide an agent through SEO tasks, and the codebase is written in TypeScript and can be forked for custom tools.
