OpenSEO
Open-source Semrush alternative, works with your agent over MCP
Visit website →About
OpenSEO takes the SEO data you pay $100+ a month for and makes it available to everyone. The project is fully open source — self-host it for free or use the cloud version at $10 per month. Data comes from DataForSEO and covers keyword research, backlinks, rank tracking, and site audits.
What sets it apart is the direct MCP connection to Claude, Codex, and Gemini. Instead of opening a dashboard and searching manually, you ask your agent to run keyword research, competitor analysis, or a technical audit — and the agent returns a ready report inside the app.
Every piece of research your agent does becomes a readable report, not raw text output. The project is new but has already reached 3,000 users, with features like AI-search visibility tracking in the pipeline.

Why we picked it
Traditional SEO tools are expensive and complex. OpenSEO breaks that pattern: open source, affordable, and built to work directly with AI agents. Instead of paying $100 and searching manually, your agent does everything at $10 a month.
