A Prague-based CDN delivering website, software, game, and live-streaming acceleration on a usage-priced global network.

CDNsun is a content delivery network provider operated by CDNsun s.r.o., a company registered in Prague, Czech Republic. Founded in 2012, it offers caching and acceleration for websites, software downloads, game distribution, and live video streaming.

Its network spans data centers worldwide, and pricing is generally usage-based rather than tied to long-term contracts. As a Czech-registered company, it operates under EU jurisdiction and GDPR, giving European customers a smaller, regional alternative to US-based CDNs.

It has a narrower feature set and lower profile than larger competitors but a multi-year operating history in the CDN market.
