A cdn (Content Delivery Network) caches your website on servers worldwide. Visitors load your site from the nearest node, reducing latency. For VPS users, a free CDN is one of the highest‑leverage upgrades you can make.
Here are 10 free CDN services for your VPS.
1. Cloudflare (Free tier)

Cloudflare is the default choice for most VPS users. The free tier includes a global CDN with 300+ data centers, shared SSL certificate, DDoS protection, and basic firewall rules. It's easy to set up: just change your nameservers.[reference:0]
Tradeoffs: You're proxying traffic through Cloudflare, which can complicate debugging. Advanced features (WAF, page rules) are limited on free tier.[reference:1]
2. Bunny CDN (Free trial)
URL: https://bunny.net
Bunny is known for raw performance and straightforward pricing. The "free tier" is typically a trial or promotional offer rather than an always‑free plan.[reference:2]
Best for: Users who want a clear upgrade path from free to paid. Performance is excellent, especially in Europe and North America.
3. Fastly (Free tier)
URL: https://fastly.com
Fastly offers a generous free tier with 50 GB bandwidth per month. It's developer‑friendly with powerful caching logic and real‑time purging.[reference:3]
Best for: Developers who need fine‑grained caching control. The free tier is weaker for typical indie VPS setups but excellent for custom logic.
4. KeyCDN (Free tier)
URL: https://keycdn.com
KeyCDN offers 25 GB free bandwidth per month (for new accounts). It uses HTTP/2 and supports real‑time purging. Pay‑as‑you‑go pricing after free tier.[reference:4]
Best for: Video delivery and HLS‑style workflows. Stronger for HTTP delivery than all‑in‑one video platforms.
5. AWS CloudFront (Free tier)
URL: https://aws.amazon.com/cloudfront/
CloudFront offers 50 GB data transfer and 2 million HTTP requests free each month for the first year. Powerful but complex to configure.[reference:5]
Tradeoffs: CloudFront is often 18x more expensive than Bunny CDN for similar workloads.[reference:6] Not recommended for cost‑sensitive projects.
6. 5centsCDN (Free tier)
5centsCDN offers a free tier with 100 GB bandwidth per month. Pay‑as‑you‑go pricing after that. Competitive for low‑traffic websites.[reference:7]
Tradeoffs: Customer service can be slow and unresponsive. Interface could be improved.
