Overview
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.

Pricing

Uploadcare CDN uses a pay-as-you-go (PAYG) model with a free tier for low-volume users. Paid plans start at $20/month, with per-GB pricing for CDN traffic and storage. For example, the Regular plan includes 100 GB of CDN traffic for $49/month. A free tier offers limited monthly CDN traffic, suitable for testing or small projects. Enterprise plans are available for custom needs. Full details are at https://uploadcare.com/pricing/.
Integrations & DevEx

Uploadcare provides a REST API and webhooks for programmatic control, with SDKs for JavaScript, Python, and other languages. Its React Uploader component simplifies file uploads in React applications. Real-time logs are available for monitoring, and instant purge is supported via API. No Terraform or CI/CD pipeline integrations are documented. The platform includes a dashboard for managing files and monitoring usage, aimed at developers and content teams.
When it fits
—
- Small to medium businesses needing a developer-friendly CDN for media-heavy web or mobile apps.
- Projects requiring robust image optimization and video-on-demand delivery with simple API integration.
- Teams on a budget leveraging the free tier or PAYG pricing for low-to-moderate traffic.
When it doesn’t
—
- Enterprises needing advanced security features like WAF, DDoS protection, or bot mitigation, which are not offered.
- Applications requiring live video streaming, DRM, or complex edge compute capabilities.
- Organizations needing detailed network transparency or extensive POP coverage, as specific network details are limited.
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.
