OpenSEO

Pay-as-you-go keyword research, rank tracking and site audits on your Cloudflare account, with an MCP server for agents

What a Sitebulb user would miss
It has no data visualizations; it covers full Sitebulb hint library and PDF reports only in part; the crawler runs on Cloudflare Workers, and JavaScript-rendered audits need a Workers Paid plan according to the project docs.
What it adds
It runs as a web app in your Cloudflare account and also covers keyword research, rank tracking, backlinks and AI visibility.
