OpenSEO

OpenSEO is an open source SEO platform that enables keyword research, site audits, and rank tracking via AI agent integration and usage-based billing.

OpenSEO functions as an open source alternative to traditional SEO suites, focusing on data-driven tasks like keyword research, backlink analysis, and technical site audits. The platform connects to AI agents through the Model Context Protocol (MCP), allowing users to integrate SEO workflows into environments like Claude, Cursor, and ChatGPT. It uses DataForSEO for its core data and stores project context so agents learn business-specific requirements over time. Users can self-host the tool or utilize the hosted version. The service structures billing by usage rather than high fixed monthly fees, allowing credits to roll over for top-ups. This approach differentiates the product by providing raw SEO capabilities without the overhead typical of large commercial platforms.
