Our verdict: worth using

Semrush/Ahrefs alternative (keywords, rank tracking, backlinks, audit, AI visibility, MCP). Self-hosts via Docker, fits the PC. AGPL-3.0: run it as a separate service taskdriver calls over HTTP/MCP and borrow its panel set freely; do not paste its source into the client-facing taskdriver app. Needs a pay-as-you-go DataForSEO key for any data (2026-09-23).
