Global Multi-CDN powered by jsDelivr
esm.run is powered by jsDelivr and it's sponsors like Cloudflare, Fastly, Bunny, Quantil, and appfleet. This guarantees the best performance and uptime globally, including mainland China.
On-demand builds with permanent storage
Once built, files are stored in a permanent storage shared by all edge servers. That means future access will be always fast, even for files not yet cached at the CDN edge.
State-of-the-art delivery
HTTP/2, HTTP/3, code minification, brotli compression, fine-tuned HTTP caching, dependency preloading - we always use all available options for improving the overall performance.
