OpenSEO

OpenSEO is a self-hosted SEO platform built for teams that want full control over their SEO data without paying recurring fees to tools like Semrush or Ahrefs. It's MIT-licensed and runs on Docker or Cloudflare, so you own the infrastructure and the data.

The platform covers the core workflows most SEO teams rely on:

• Keyword research for discovering and organizing target terms
• Backlink analysis to understand link profiles for any domain
• Competitor insights to monitor what competing sites are ranking for
• Rank tracking to follow keyword positions over time
• AI visibility to understand how your content appears in AI-generated search results

It connects to the DataForSEO API, which means you bring your own API key and pay for data directly rather than through a platform markup. That model works well for agencies or in-house teams with predictable data needs who want to cut out the subscription layer.

Because the source is fully open, teams can fork the codebase and build custom workflows on top of it. That's a real advantage if your SEO process doesn't fit neatly into what commercial tools offer. An Ubersuggest or Semrush subscription locks you into their interface; OpenSEO doesn't.
