CDN Guide: Free SSL & Let’s Encrypt Supported Content Delivery Networks

In this post I am listing CDN “Content Delivery Network” providers that offer free SSL/TLS certification in May of 2024. Either by supporting the free certificate authority “Let’s Encrypt” or an option for a shared certificate.

Please note that you will likely need a separate SSL certificate for your main domain — these are being offered by many shared hosting companies and VPSes.

Let's Encrypt CDN

Note: The amount of server locations or “Points of Presence/PoPs” is not everything, I have provided very basic stats for reference only.

Each static CDN has a “certs.” option in the backend — where you can easily assign the desired SSL/TSL certification to your subdomain, letsencrypt certificates are renewed automatically.

All new CNAMEs are redirected to HTTPS by default with a ready installed Let’s Encrypt certificate, which is automatically maintained and renewed by CDN77.


Switzerland based company KeyCDN, profiled as a high-speed, simple and scalable CDN was founded in 2012. It’s integration with Let’s Encrypt has made SSL management super easy with automatic certificate renewals.

CDNs Without Let’s Encrypt Support:

StackPath (MaxCDN)

MaxCDN and StackPath joined forces in 2016 to create a security focused, machine learning Content Delivery Network. No support for Let’s Encrypt is planned but options for free shared SSL or custom SSL are provided.


By using a CacheFly subdomain (e.g. you may use a free shared SSL/TSL certificate. For own subdomains SSLs are $500 to start with a yearly recurring fee of $100, wildcard certificates cost more.

This list is updated as the situation develops.

Final Words

While many hosting companies are stepping up to support Let’s Encrypt (also known as LetsEncrypt) — CDNs have been somewhat slower to adapt. One reason is smaller demand with the abundance of high-end users, and simply there are less CDN providers than hosting companies. Nevertheless, the more common CDN use becomes, the higher the demand for free CDN encryption.

These companies lead the times. Good luck.
