CDNsun
What CDNsun is
CDNsun is a content delivery network for accelerating websites and distributing software, games, advertising, live streams, and on-demand video. Its network has more than 30 data centers across five continents, with SSD-equipped edge servers. For websites, it caches static assets—including images, CSS, fonts, and JavaScript—to speed their delivery. Software and app creators can use the service to distribute mobile apps, desktop applications, updates, and static app content globally.
The listed integrations cover content management and commerce systems, web frameworks, video tools, Cloudflare, and Amazon S3. They include WordPress, Joomla, Drupal, TYPO3, Magento, PrestaShop, OpenCart, React, Next.js, Django, FFmpeg, and JW Player. A REST API can prefetch content to edge servers, and API use has no additional charge. Up to 5 GB of storage is free; larger amounts are priced separately. Stored files can be uploaded through FTP, FTPS, SFTP, RSYNC, or HTTPS API. CDNsun describes authentication, encryption, and content integrity as security priorities, and says custom SSL is included at no extra cost. A 15-day free trial and 24/7 support by email, phone, and live chat are available. The Business Plan is $0.03 a month, billed at $0.030 per GB with no monthly fees; the Custom Plan is $200 a month as a minimum spend.
