What it is	No more fact-checking. No fabricated sources. Just AI you can trust	OpenSEO is the open source alternative to Ahrefs and Semrush. Keyword research, backlinks, rank tracking, and site audits, billed by usage instead of a $100-plus monthly subscription. Self-host it free, or connect it to your AI agents over MCP.	Runs a longer research task and returns a report, a spreadsheet or a small app rather than an answer.
