FAQ

Is Free CDN Really Enough?

For websites with monthly traffic under 1TB, free CDN (especially Cloudflare) is completely sufficient. Cloudflare's free plan doesn't even have traffic limits, and many medium-sized websites continue using the free plan.

Does Free CDN Affect Website Stability?

Mainstream free CDNs (like Cloudflare, jsDelivr) all have high-availability architecture with stability comparable to paid plans. However, if you have extremely high stability requirements, consider paid plans with SLA guarantees.

Can I Use Multiple Free CDNs Simultaneously?

Yes, this is a common practice. For example: use Cloudflare as main CDN, use jsDelivr for frontend libraries, use Statically for images. This maximizes the use of each service's free quota.

Does Free CDN Collect User Data?

Policies vary by service. Cloudflare has clear privacy policies and doesn't sell user data. Read each service's privacy policy before using to ensure GDPR compliance.

How to Upgrade from Free to Paid Plans?

Most CDNs (like Cloudflare, Bunny CDN) offer smooth upgrade paths—just select the upgrade plan in the dashboard. Settings are usually retained automatically without service interruption.
