  • Free Trial

Description

OpenSEO is an open-source SEO platform that covers keyword research, backlink checks, rank tracking, site audits and AI search visibility. Instead of a large flat subscription, you pay a small monthly fee and then pay for the data you actually use. You can also host it yourself for free.

It is built to work with AI agents: an MCP connection lets tools such as Claude, Codex and Gemini run SEO research for you.

Who OpenSEO Is For

  • Founders and business owners growing organic traffic on a budget
  • Marketers who use AI agents and want SEO data available inside them
  • Developers and technical teams who prefer to self-host and customise their tools

Core Capabilities

Keyword Research

Find keyword ideas with search demand, difficulty, intent and the live search results for each one, then save the best opportunities into lists.

Competitor and Backlink Analysis

A domain overview estimates a competitor organic traffic and ranking keywords. The backlink tool shows referring domains and link quality.

Rank Tracking and Site Audits

Track keyword positions over time, and crawl your site to flag page-level and technical SEO problems.

AI Visibility

Research prompts, track when AI models mention or cite you, and compare how different models answer the same question.

Built for AI Agents

The OpenSEO MCP and a Search Console MCP give agents direct access to your SEO data. Project Context remembers what an agent has learned about your business between sessions, and Agent Reports save research as readable documents.
