Are these tools free?

Yes. Every tool on this page is free to use. None of them requires an account, a credit card, or the SEOAgent Skill.

Do the tools change my site?

No. The checkers and the grader read a public URL or a repo and show a result on the page. Nothing is written to your site or your repo. The SEOAgent Skill, which runs inside your coding agent, is the part that proposes file changes, and you approve each one.

Why are three of the tools about Lovable?

Lovable-built sites ship client-rendered by default, so they have their own indexing problems. Those three pages belong to LovableSEO, the sister product for Lovable sites. They are listed here so the full set of free tools is in one place.

Free SEO tools

SEOAgent publishes 6 free tools. Three work on any site or any coding-agent skill: an AI-readiness checker, a skill grader, and a live SEO skill benchmark. Three are for Lovable-built sites. None of them needs an account.

For any site and any skill

Paste a URL or a repo and get a result on the page. These are the checks the SEOAgent Skill runs before it proposes fixes in your codebase.

What the tools show, and what the Skill fixes

Each checker reports a problem: a site with no llms.txt or OKF bundle, a skill that loads too much context, a Lovable site Google cannot render. The tools stop there. They do not touch your site.

The SEOAgent Skill picks up where the tools stop. It runs inside Claude Code, Cursor, or Codex, audits the site from the repo it is built from, and drafts the fix as a real file change. You approve the diff before anything ships.
