Overview

KeyCDN is a content delivery network (CDN) provider founded in 2012, headquartered in Wilen, Switzerland. It specializes in accelerating the delivery of web content, such as HTML, JavaScript, images, and videos, through a global network of edge servers. The service is designed for businesses of all sizes, from small blogs to enterprise websites, offering features like real-time analytics and DDoS protection. KeyCDN emphasizes ease of integration with a user-friendly dashboard and API, making it accessible for developers and SMBs. It supports a wide range of use cases, including e-commerce, media, and gaming, with a focus on performance and security.
Peer5 operated a peer-to-peer (P2P) content delivery network (CDN) specializing in live video streaming, leveraging WebRTC for in-browser, clientless enterprise CDN (eCDN) solutions. Founded in 2012, the company was acquired by Microsoft in August 2021 to enhance video streaming capabilities in Microsoft Teams. Peer5’s technology optimized bandwidth usage through self-balancing mesh networks, serving large-scale enterprise events with up to 2 million concurrent users. As of 2025, Peer5’s standalone services are defunct, with its technology integrated into Microsoft’s eCDN for Teams.

Network & Architecture

KeyCDN operates over 50 points of presence (POPs) across North America, Europe, Asia-Pacific, Latin America, and other regions, ensuring global coverage. Its network leverages SSD storage and HTTP/3 for efficient content delivery. The service uses a tiered caching system and supports origin shielding to reduce load on origin servers. KeyCDN has strong peering agreements with major ISPs, optimizing latency and throughput. Its regional strengths include robust performance in North America and Europe, though coverage in Africa and parts of Asia may be less extensive compared to larger providers like Cloudflare or Akamai.

Pricing

KeyCDN uses a pay-as-you-go (PAYG) model with no minimum commitments, making it SMB-friendly. Pricing starts at $0.04 per GB for the first 10 TB in North America and Europe, with higher rates for other regions like Asia ($0.14/GB) and Oceania ($0.19/GB). A 30-day free trial includes 10 GB of traffic. Additional features like DDoS protection are included at no extra cost, though custom SSL certificates may incur fees. Full details are available at https://www.keycdn.com/pricing.

Integrations & DevEx

KeyCDN provides a robust API for automating tasks like cache purging and zone management, supporting an API-first workflow. Real-time logs and analytics are accessible via the dashboard or API, with log push capabilities for integration with external systems. It offers plugins for platforms like WordPress and Magento, simplifying setup for non-technical users. Terraform support is not available, but the API covers most automation needs. Migration tools are limited, though the dashboard supports easy configuration for importing assets from origin servers.

When it fits

  • Small to medium-sized businesses needing a cost-effective, easy-to-use CDN with global reach and real-time analytics.
  • Developers seeking an API-first CDN with features like instant purge and signed URLs for dynamic applications.
  • Websites with heavy image or VOD content, leveraging KeyCDN’s optimization and delivery capabilities.

When it doesn’t

  • Enterprises requiring advanced edge computing or serverless functions, which KeyCDN does not offer.
  • Users needing extensive coverage in Africa or niche regions where KeyCDN’s POP density is lower than competitors like Cloudflare.
  • Applications requiring specialized video features like live streaming or DRM, which are not supported.

History & Notes

Peer5 was known for its innovative use of WebRTC to create a decentralized, browser-based P2P CDN, reducing server load and improving video delivery for large audiences. The company powered events for over 1 billion users before its acquisition. No official EOL announcement for standalone services was found, but Peer5’s website now redirects to Microsoft’s eCDN page, indicating full integration. Some third-party sources mention continued support for existing Peer5 customers post-acquisition, but this is unconfirmed as of 2025.
