Preflight: website launch checks

Launch checks for Webflow, Framer, WordPress, Shopify, Wix and coded sites: SEO, accessibility, speed, links and build leftovers.

Preflight checks any website for launch issues, right from your browser. Open the page, click the Preflight icon, and get a clear list of what to fix before you publish. Works on sites built with Webflow, Framer, WordPress, Shopify, Wix or custom code, on staging or live. WHAT IT CHECKS • SEO: page titles, meta descriptions, heading structure, canonical tags and social share previews • Accessibility: missing alt text, heading order and other common issues • Speed: heavy images and assets that slow the page down • Links: broken links and links still pointing to staging or placeholder URLs • Build leftovers: placeholder text, test content and other bits left behind from the build WHO IT'S FOR Designers, developers, agencies and freelancers who ship websites and want one last pass before going live or handing a site over to a client. HOW TO USE 1. Open the page you want to check. 2. Click the Preflight icon in your toolbar. 3. Review the results and fix any issues before you publish. FREE AND OPEN SOURCE Preflight is free and open source. It's built by Rango (https://rango.design/), AI-native design & engineering partner for Products & Websites, from the checks we run before every website we ship.
