What are the best open-source Surfer SEO alternatives?

No open-source project replicates Surfer's live content score in a browser editor. SEO Machine and claude-seo run inside Claude Code under the MIT licence, and OpenSEO is a self-hosted research suite. All three cost nothing to license but need your own API keys or Claude Code.
