From install to edge URL in minutes

Serve the exact library your app needs, without owning CDN infrastructure.

CacheStatic resolves package versions, pins immutable assets, compresses responses, and keeps hot libraries close to users. Use it for public frontend dependencies, design-system bundles, documentation sites, widgets, and private distribution.

Library delivery

Popular packages stay warm at the edge.

Search common frontend libraries, inspect recommended entry points, and copy stable URLs for version-pinned delivery.

Production UMD builds, JSX runtimes, and pinned ecosystem packages.

Vue

ESM and browser bundles for progressive apps and embedded widgets.

Three.js

Fast delivery for WebGL renderers, controls, loaders, and examples.

Global edge network

Low-latency package delivery with cache behavior you can reason about.

CacheStatic uses deterministic keys, immutable release URLs, and adaptive regional prewarming. Your application loads the same artifact everywhere while the nearest edge location handles compression, TLS, and stale-while-revalidate policies.

Immutable by defaultVersioned URLs can be cached for a year.

Smart compressionBrotli, gzip, and content negotiation per request.

Subresource integrity

Generate SRI hashes for pinned assets and enforce secure browser loading.

Private package mirrors

Expose approved internal libraries through scoped, token-protected edge URLs.

Real-time analytics

Monitor cache hit ratio, region latency, popular versions, and error budgets.

Release controls

Pin, alias, freeze, deprecate, or roll back package versions without redeploying apps.

Security and governance

Package delivery built for teams that need control.

Lock down who can publish aliases, require integrity metadata, block vulnerable versions, and keep audit logs for every asset promoted to production.

Signed manifestsEvery resolved asset can be tied to a signed manifest.

Version allowlistsApprove exact semver ranges before they reach the edge.

Team rolesSeparate library maintainers, reviewers, and billing admins.

Incident controlsPurge, freeze, and revoke compromised packages quickly.

FAQ

Common questions before production rollout.

Can we pin exact versions?

Yes. Exact version URLs are immutable and designed for long browser and edge cache TTLs.

Do you support ESM?

Yes. CacheStatic can serve browser-ready ESM entry points and package-specific module paths.

Can private packages be exposed safely?

Private mirrors use scoped tokens, allowlists, signed manifests, and optional IP restrictions.

How fast are purges?

Critical purges are propagated globally in seconds, while immutable assets usually do not need purging.

Ready for faster library delivery?

Put JavaScript dependencies on an edge network designed for frontend teams.
