What hackers pick instead
- CloudflareRecommended for strong DDoS and bot protection and shielding origin servers, much of it free or cheap, though critics cite outages that take down huge parts of the web.744recommend
- Bunny.netA cheap, pay-as-you-go European CDN with edge scripting, popular as a Cloudflare alternative, though critics cite a data-loss bug downplayed for 15 months and a poorly handled security incident.121recommend
- Amazon CloudFrontRecommended for cheap, fast content delivery with a free tier and tight S3 integration. Critics note its SLA is only three 9s.24recommend
- Cloudflare CDNPeople recommend it for a free CDN tier with no bandwidth fees, speed and reliability; critics object to its centralizing power and its traffic inspection.12recommend
- Cloudflare Workers CacheLets Cloudflare Workers return cached responses without running the worker again, with cache tags for invalidation. Critics warn it may raise bills because of how requests are counted.10recommend
