Overview
Universal CDN, founded in 2015 and headquartered in Sofia, Bulgaria, offers a global content delivery network focused on delivering web content, video streaming, and live media. It serves businesses ranging from small startups to large enterprises, particularly those needing video-on-demand and live streaming capabilities. The service emphasizes an API-first approach, enabling developers to integrate and manage CDN services programmatically. Universal CDN supports a variety of use cases, including e-commerce, media, and gaming, with a focus on performance and real-time analytics.
Viblast was a Bulgaria-based company founded in 2013 that specialized in peer-to-peer (P2P) video streaming solutions, offering Viblast PDN and Viblast Player for live and on-demand video delivery. It served broadcasters, content providers, and CDNs, leveraging WebRTC and HTML5 to enable plugin-free HLS and MPEG-DASH playback. The company aimed to reduce bandwidth costs and improve stream quality for high-concurrency live streams. As of 2023, Viblast is reported as out of business, with no active services or official website available.
Network & Architecture
Universal CDN operates a global network with points of presence (PoPs) across North America, Europe, Asia-Pacific, and Latin America. Specific PoP counts are not publicly disclosed, but the provider claims broad coverage with optimized routing for low latency. It leverages partnerships with major ISPs for peering, enhancing delivery speeds. The service is particularly strong in Europe and North America but has less presence in Africa and the Middle East, which may limit performance in those regions.

Integrations & DevEx
Universal CDN provides an API-first design for seamless integration with developer workflows. It supports real-time logs for immediate performance insights but lacks Terraform support or advanced IaC tools. SDKs are available for common programming languages, facilitating integration with CI/CD pipelines. The platform does not offer built-in migration tools but provides documentation for transitioning from other CDNs.
