What it is
A self-hostable SEO workbench covering keyword research, rank tracking, technical audits and AI-visibility checks in one app you own. It ships an MCP server, which means an AI assistant can drive it.
What it is good for. The commercial equivalents run $99–200 a month, and early on that money is better spent on hosting. The MCP server is the part that matters: instead of learning another dashboard nobody opens, you ask Claude Code "which keywords is this competitor ranking for that we aren't?" and it queries this directly. It pairs cleanly with advertools from Edition 1 — advertools generates and crawls, OpenSEO tracks and reports.
- MIT and self-hostable, with no per-seat pricing to grow into
- The MCP server means Claude Code drives it — which suits a terminal workflow far better than any UI
- Pay-as-you-go on the underlying data instead of a flat monthly subscription
- Still v0.1.x — young software, expect breaking changes and rough edges
- Keyword and SERP data still comes from paid providers. "Free" here means cheaper, not no bill
- Another Node and Postgres stack to patch, on a VPS that is steadily getting busier
