Is your website ready to launch?

Paste your site and get a plain list of what to fix before launch day: how it loads, how it looks when it is shared, and whether search engines can find it. Free, no account.

What it checks

The basics

The page loads over HTTPS with a valid certificate, answers quickly, fits a phone screen and has a favicon.

Search engines

A title and meta description of the right length, no stray "noindex", a canonical URL, a main heading, a declared language, robots.txt and sitemap.xml — and llms.txt for AI assistants.

Link previews

The Open Graph image and text and the X card that decide how your link looks when it is shared on launch day.

Planning the rest of the launch too? Work through the launch checklist.
