jsDelivr jsDelivr is a public content delivery network for JavaScript libraries, CSS frameworks, and static assets. It delivers files from open-source projects and commercial vendors through a multi-provider network combining commercial CDNs, peer-to-peer technologies, and cloud infrastructure. The service is used by developers, projects, and organizations to accelerate delivery of web assets across global edge locations.
Overview
jsDelivr operates as a distributed content delivery network serving static assets for web applications, integrating multiple upstream providers and edge caches. It interconnects with major infrastructure providers and open-source ecosystems to provide redundancy for popular libraries, frameworks, and tools. The platform is commonly compared and referenced alongside other distribution services used by projects and organizations across the software industry.
History and development
The project started in 2012 to address reliability and performance concerns for hosting libraries used by popular projects. Early contributions and growth involved participants from the open-source community, foundations, and independent developers. Over time, the service incorporated partnerships with commercial providers and adopted technologies popularized by projects and corporations. Milestones include adopting multi-CDN routing, integration with package repositories, and supporting modern packaging ecosystems used by many projects.
Architecture and features
jsDelivr's architecture is layered, combining multiple CDN providers, edge caching, and origin storage. It supports static file hosting for assets versioned by package registries and repository hosting services used by numerous projects. Features include automated failover, regional routing, HTTP/2 and HTTP/3 support, and asset purging mechanisms employed by many cloud platforms and infrastructure providers. The network integrates with package ecosystems and repository hosts that are widely used in software development.
Performance and reliability
Reliability goals are achieved by multi-provider redundancy, geographically distributed edge locations, and traffic steering employed by major cloud and networking companies. Latency and throughput are improved for end-users located in diverse regions through peering and exchange points adopted by large operators. Availability practices mirror those used by high-traffic services and enterprise platforms, with monitoring and metrics influenced by observability tools and standards used across the industry.
Usage and adoption
jsDelivr is widely used by open-source projects, developer tooling, content creators, and commercial sites to serve libraries, assets, and builds. Many projects distribute minified assets and builds through the network to leverage caching and global delivery. Adoption spans independent projects, large projects, and organizations that publish front-end libraries, frameworks, and design systems.
Governance and funding
The project is community-oriented, with governance influenced by contributors and maintainers from diverse backgrounds. Funding and operational costs are covered through donations, sponsorships, and partnerships common among infrastructure projects. The model reflects approaches used by other community-supported services and infrastructure initiatives.
