Bunny.net vs Cdnjs

What Bunny.net is

Bunny.net is a CDN and edge storage service priced considerably below the large providers. It covers the common case well: cache static assets, stream video, store origin files at the edge. It is not trying to be a full edge-compute platform, so if you need heavy programmable logic at the edge the comparison goes the other way.

What Cdnjs is

cdnjs is a free, community-run CDN for open-source web-library assets, delivered through Cloudflare. Consumers select a library, exact version and file, then reference its public URL; the service also exposes library metadata through an API. Example markup published by Cloudflare uses a versioned URL and Subresource Integrity attributes. cdnjs' code repository is MIT-licensed, but each distributed library keeps its own license. It is a dependency-delivery service rather than private storage, a package-security review or a contractual availability guarantee.

What Bunny.net is built to do

Global CDN

Caches and serves static assets from edge points of presence.

Edge storage

Stores origin files in replicated regions close to the CDN.

Video streaming

Transcodes and delivers video with a hosted player.

What Cdnjs is built to do

Library catalog

Indexes versioned files from supported open-source JavaScript and CSS libraries.

Cloudflare delivery

Serves cached public assets through Cloudflare's network.

API access

Exposes library, version and file metadata for discovery and tooling.

Integrity-ready snippets

Provides examples and hashes that can be used with browser SRI and crossorigin attributes.

Choose Bunny.net if

• Sites whose traffic is mostly Europe and North America — $0.01/GB on the standard network
• Video or download-heavy projects that can use the Volume network at $0.005/GB
• Small projects: the minimum charge is $1/month and there are no per-request fees

Skip Bunny.net if

• Most of your users are in the Middle East, Africa or South America — those regions cost $0.06 and $0.045/GB
• You need an enterprise contract with named support; bunny.net sells self-serve first
• You expect a permanent free tier: there is a 14-day trial, then usage billing

Choose Cdnjs if

• Sites that want a free public CDN — every file is served from Cloudflare's global network
• Projects at scale: the service reports 250B+ requests per month and use on 12.5% of all websites
• Teams that do not want to self-host popular JavaScript, CSS and font libraries

Skip Cdnjs if

• You need a contractual bandwidth or rate-limit guarantee — none is published
• Your compliance rules forbid loading assets from a third-party network you have no agreement with
• You depend on a sponsor-funded service staying free; funding comes from donated infrastructure

Bunny.net: pros & cons

• Very low cost per gigabyte
• Simple pricing and dashboard
• Edge storage and image optimisation included
• Fewer edge compute features
• Smaller enterprise support organisation
• Fewer compliance certifications

Cdnjs: pros & cons

• No-cost public delivery: Supported open-source library assets are served globally through Cloudflare.
• Versioned paths: URLs can identify an exact library release and file for reproducible front-end loading.
• Integrity metadata: Published examples support browser Subresource Integrity checks when the correct hash is used.
• Open project and API: Public repositories and metadata endpoints make the catalog inspectable and automatable.
• Catalog scope is narrow: It is not private asset storage or a general-purpose origin/CDN product.
• Package trust remains external: CDN availability does not prove that a library release or transitive code is safe.
• Third-party dependency: Page delivery, privacy posture and CSP must account for requests to an external domain.
• Licenses vary: The cdnjs repository license does not replace the license of each hosted library.
