Free tools
Three things you can fix today, free.
No signup, no email, no credit card. Each runs the same kind of check Xeostack runs across your whole site — these just do one page, and each page says plainly where it stops.
llms.txt generator
Paste a URL. Get an llms.txt you can publish today.
Open the tool →Schema markup generator
See what structured data you already have, and what is missing.
Open the tool →Sitemap XML generator
Build a valid sitemap, and see what your robots.txt already declares.
Open the tool →Ten runs an hour per visitor. None of them crawl your site — they read the one page you give them, which is what keeps the tools free and keeps us from being pointed at somebody else’s server.
