The service is not affiliated with or supported by npm, Inc.
Key Features
- Direct npm access - Load any package file via URL without build tools
- Semantic versioning - Supports version ranges, tags, and exact versions
- Metadata API - Query package information programmatically
- No-build development - Enables browser-native ES modules without bundlers
Infrastructure
unpkg runs entirely on Cloudflare's edge network using Cloudflare Workers, serving billions of requests daily from hundreds of global locations.
