jsDelivr

The organisation operates an infrastructure platform that provides global CDN delivery of open-source package assets at no direct charge to users. Value is created by aggregating and caching files from npm, GitHub and other registries, distributing them via a resilient multi-CDN and multi-DNS network, and simplifying asset delivery for developers and site operators. Revenue and infrastructure cost coverage come from a mix of corporate sponsorships, donations and in-kind contributions such as bandwidth and DNS services from partner providers. There is no indication of paid usage tiers, per-request billing or traditional SaaS contracts; instead, the model resembles an open-source infrastructure project sustained by sponsors in exchange for visibility and community goodwill.

jsDelivr is a free, public content delivery network (CDN) focused on serving files for open-source software projects. It automatically delivers assets such as JavaScript, CSS and other resources directly from npm, GitHub and similar registries via a multi-CDN and multi-DNS architecture operated by ProspectOne in Poland.

The service does not charge users and is funded through corporate sponsorships, donations and in-kind infrastructure support from CDN and DNS providers. Its primary users are web developers, open-source maintainers and organisations that embed open-source libraries into websites and applications, relying on the network for global asset distribution and caching at no direct cost.
