Privacy and analytics
Updated October 31, 2026. JavaScriptLibraries.com uses Google Analytics 4 to measure visits and page interactions. The Google tag loads when a page opens. Google may receive page URLs, online identifiers, device or browser details, and interaction data under its own policies.
Local preferences
Your comparison selection is saved in this browser’s local storage so it remains available as you browse. The Google tag does not read that stored value directly. When you open a comparison, selected package names can appear in the page URL, which Google Analytics receives as page URL data.
Service providers
Cloudflare hosts and protects the site and may process request metadata. The site also requests package information from npm and other sources described in Data sources and methodology.
