OpenSEO

What is OpenSEO?

Open-source keyword, backlink, rank tracking and site audit tool that AI agents can drive over MCP.

Who is OpenSEO best for?

OpenSEO is best for founders and small teams who want keyword and backlink data inside Claude or Codex.

• SEO from an AI agent

  The OpenSEO MCP and skills let Claude, Codex, OpenCode or Gemini run keyword research, audits and competitor analysis, and each result is saved as a report.

• Small sites on a budget

  Base costs $10 a month with $10 of data included, and you pay only for the lookups you run.

• Teams that want to self-host

  The MIT-licensed code runs on Docker or a free Cloudflare account, with your own DataForSEO key.

• AI search visibility

  Prompt Explorer and AI visibility checks show how AI models mention a brand, at about $0.002 per prompt check.

How much does OpenSEO cost?

OpenSEO is free to self-host under the MIT licence with your own DataForSEO key; the hosted Base plan costs $10 a month and includes $10 of data usage.

Usage pays for new data at DataForSEO's cost plus a flat 28%: a keyword search is about $0.05, a rank check up to 1.5 cents per keyword and an AI prompt check about $0.002. Saved results, exports and Google Search Console data use none. Extra usage is sold on paid plans and never expires; included usage resets each month. Paying yearly gives 2 months free, and a free trial comes with $0.50 of credits. Full pricing on openseo.so. We checked these prices on 8 Nov 2026.
