About OpenSEO

What it is

OpenSEO covers the standard SEO toolkit — keyword research with volume and difficulty, domain and traffic overview, backlink inspection, rank tracking and technical audits — and adds AI-visibility tracking for whether a brand shows up in AI-generated answers. All of it is available through a web app and through the Model Context Protocol, so Claude Code or Cursor can query it directly. It is open source and self-hostable.

Why it's different

The pitch is Ahrefs and Semrush without the four-figure annual commitment, which is a real gap for small sites. Two things temper it. SEO tools are only as good as their crawl index, and an index is enormously expensive to build and maintain — so keyword volumes and backlink coverage here will be thinner than the incumbents, whatever the feature list matches. The AI-visibility tracking is also newer than anyone's methodology for it, so treat those numbers as directional at best.

How people use it

It suits solo operators and small agencies who need the numbers occasionally and cannot justify an enterprise seat. The MCP integration is the more interesting half: an agent that can pull keyword and ranking data mid-task can draft content against real search demand rather than guesses. Self-hosting is worth it if you are running audits for multiple clients and would otherwise pay per seat.
