OpenSEO is an open-source SEO platform covering keyword and backlink research, rank tracking, site audits and AI answer tracking, built to be used through agents like Claude and Codex as well as its own web app. The hosted plan is $10 a month with $10 of usage. But heavier use costs extra, included credits reset monthly, and self-hosting still means paying DataForSEO for the data. - **Value for money: A.** $10 a month with $10 of usage included, under 60% of this category's cheaper quarter. The vendor's estimate is about $0.05 per keyword search and $0.08 per domain overview. Heavier use is bought as top-ups, with a 28% fee on DataForSEO requests. - **Free plan and trial: C.** Self-hosting is free, but you pay DataForSEO for the data, with a $50 minimum top-up. The hosted trial gives $0.50 of credits with no card, about ten keyword searches. - **Features: B.** Keyword research, domain and backlink research, rank tracking by location and device, site audits, AI answer tracking and an MCP server for agents, all on one plan. It covers the whole job, though AI tracking names only ChatGPT, Gemini and AI Overviews. - **Ease of use: C.** No rating on record. The web app and agents both run on usage credits you'll want to watch, and self-hosting means Docker or Cloudflare plus a DataForSEO key. - **Platforms and integrations: B.** Web only, connected to Search Console, DataForSEO, Claude, ChatGPT, Codex, Cursor and Gemini through its MCP server. No desktop or phone app. These are ToolGPA's own grades. Graded from this listing, whose facts were read from OpenSEO's own pages on 23 October 2026.

That is not a weekend's work, with an AI app builder or without one. It is one of the better ones too: its GPA of 2.8 is higher than 61 of the 64 other SEO tools we grade. It costs $120 a year. OpenSEO is open source, so there is a third way: take its code and run it yourself. - You could not: Search volumes for millions of keywords, gathered and kept up to date. - You could not: An index of the links between billions of web pages. - You could not: Daily checks of where your pages rank in search results. - You could not: A crawler that checks every page of a site. - You could not: The same prompts asked of ChatGPT, Perplexity, Gemini and Google's AI answers every day, and the answers kept. - You could not: It plugs into other products, Google Search Console, DataForSEO and Claude among them. - You could not: The depth: we grade its features B, which means it covers the whole job.
