OpenSEO on a Mac

Open-source Semrush/Ahrefs alternative; hosted or self-hosted · SEO & Marketing

OpenSEO is an open-source (MIT) SEO tool; keyword research, rank tracking, competitor insights, backlinks, site audits and AI visibility; with an MCP server and Agent Skills so AI agents (Claude Code and others) can use your SEO data directly. Run it three ways: the hosted service at openseo.so (free trial, $10/month; DataForSEO data billed through OpenSEO at cost + 28%), Docker on this Mac (one click, local-only, no login), or self-hosted on Cloudflare Workers behind Cloudflare Access (free plan works). Self-hosts need your own DataForSEO key, which FrontierStack shares from the DataForSEO pane. FrontierStack monitors the instance's setup checks and your API key.
