OpenSEO - 2026 Pricing, Features, Reviews & Alternatives

OpenSEO is an open-source SEO suite licensed under the MIT licence, covering keyword research, rank tracking, backlink analysis, site audits, and AI visibility tracking. Available as a hosted web app or self-hosted via a single Docker image and compose file, it runs on any Docker-compatible machine including local PCs, home servers, or cloud servers. Search data is billed per lookup through a third-party data provider with no monthly subscription; the crawler, site audit, and Google Search Console integration are free. A user-defined monthly spending cap prevents overages for both direct users and connected AI agents.

OpenSEO targets individual site owners, developers, and teams in digital marketing, SEO, web development, local business search optimization, and AI agent tooling. Keyword research returns difficulty, volume, traffic potential, country-level and local volume by city, state, or region, keyword ideas, questions, and live top-10 SERP results. The SERP checker supports desktop and mobile in any country, city, or state. The backlink checker provides monthly link history, referring domains, anchor data, spam scores, and link intersect. Rank tracking runs on daily, weekly, or monthly schedules for desktop and mobile by country, city, or exact coordinates. The site audit executes 117 technical checks with scheduled run-to-run comparisons, Lighthouse integration, and exports formatted for coding agents. Google Search Console and Analytics are integrated in read-only mode at no cost.

OpenSEO includes an AI visibility tracker that queries ChatGPT, Gemini, Claude, Perplexity, and 120+ AI models with web search enabled, returning every source each model cites in ranked order and flagging whether the tracked site appears and at what position. An MCP server exposes 69 tools for AI agent integration, compatible with Claude, ChatGPT, Cursor, VS Code, Codex, Gemini CLI, Windsurf, and any MCP client. Pre-built agent skills cover SEO coaching, audits, keyword research, competitor analysis, Search Console review, and local SEO. Because OpenSEO is MIT-licensed and self-hostable, the full source code is readable and modifiable, all data remains in the operator's own database, and there are no per-seat fees for team deployments.
