CDNsun

CDNsun is a pay-as-you-go CDN from CDNsun s.r.o. in Prague, founded in 2012, charging $0.030 per GB in Europe and North America and $0.060 per GB in APAC and other regions. The CDNsun Business plan has no monthly minimum, which puts CDNsun with Bunny.net and KeyCDN on the no-commitment side of the pricing divide in this category. CDNsun offers a 15-day free trial.

CDNsun puts streaming and CDN storage on the same account as delivery, and requests are unlimited with DDoS protection included. For a site that stores and streams its own media, CDNsun keeps files, streams and the cache with one Czech provider rather than three.

CDNsun runs 30 points of presence across Europe, the Americas, APAC and Africa, the smallest network with a published count in this category. The CDNsun GDPR page says personal data is kept in the EU, which together with a Czech operator keeps request logs under EU jurisdiction. CDNsun prices only in US dollars, so a European business pays every CDNsun invoice in a foreign currency and carries the exchange-rate movement itself.

What CDNsun does well

• Pay-as-you-go from $0.030/GB, no monthly minimum on the Business plan
• 15-day free trial
• Streaming and CDN storage on the same account
• Unlimited requests with DDoS protection included
• Czech company, personal data kept in the EU

Where CDNsun falls short

• Prices in US dollars only, so the invoice moves with the exchange rate
• 30 points of presence, the smallest published network in this category
• Twice the European rate in APAC and other regions, at $0.060/GB
• A higher per-GB rate in Europe than Bunny.net's €0.01

Standout feature. No monthly minimum and unlimited requests: CDNsun bills delivery by the gigabyte alone, so a burst of requests for small files does not add a line to the invoice.
