About Prefix-Free

webatla tracks 2,642 live websites using Prefix-Free, 0.0% of every site we index. Download the full list of websites that use Prefix-Free as a daily JSONL export. Every record includes the domain plus DNS, WHOIS, IP address, hosting country and global rank.

Prefix-Free is a lightweight JavaScript polyfill created by Lea Verou that automatically adds the necessary vendor prefixes (-webkit-, -moz-, -ms-, -o-) to CSS properties at runtime. This allows developers to write standard, unprefixed CSS while ensuring compatibility with older browser versions that required vendor-specific property names.

Although browser vendor prefixes have become largely obsolete as modern browsers converged on standard CSS implementations, Prefix-Free was widely used in the early 2010s to simplify CSS authoring. The library operates by examining the browser's supported CSS properties and injecting prefixed versions only where needed, making it a zero-configuration, set-and-forget solution for cross-browser CSS compatibility.
