OpenSEO

OpenSEO is an open-source SEO platform that brings keyword research, rank tracking, backlink analysis, site audits, and AI visibility metrics into one dashboard. It’s built for people who want a straightforward, no-bloat alternative to expensive enterprise SEO tools. The web app connects to DataForSEO data, giving you real search volume, keyword difficulty, and live SERP results without the fluff. You can organize keywords, monitor your positions, and crawl your site for technical issues — all in a clean interface.

What sets OpenSEO apart is its support for the Model Context Protocol (MCP). This lets AI agents like Claude, Gemini, or Codex query your SEO data directly. Instead of guessing, your agent can research keywords, analyze competitors, and check backlinks, then present the findings inside OpenSEO for you to review. The tool also includes a Prompt Explorer to compare how different AI models respond to the same SEO prompts, and an AI Visibility feature that tracks mentions and citations across AI-generated content.

OpenSEO is best for SEO professionals, content marketers, and website owners who want full control over their SEO toolkit without paying for features they don’t use. You can self-host it, extend it, or use the hosted version. Whether you’re building a content plan, tracking rankings, or auditing your site, OpenSEO gives you the essentials — and lets your AI assistant help along the way.
