What is a CDN?
A content delivery network caches and serves static assets from edge servers near each user, cutting latency and origin load. Modern CDNs bundle more than caching — DDoS protection, a web application firewall, and edge compute that runs code close to users.
Latency and bandwidth cost are direct product levers, and a CDN is the cheapest way to improve both. Increasingly the CDN is also the edge-compute platform, so the choice shapes where your code can run, not just how fast assets load.
How to choose
What separates the CDN options.
Number and placement of edge locations decide real-world latency for your users.
Egress is the bill; a media-heavy site cares a lot about per-GB cost and free tiers.
If you want to run code at the edge, check the programmability and runtime.
DDoS protection and a WAF often come bundled, which can replace a separate vendor.
Best CDN for your use case
| If you need… | Reach for | Why |
|---|---|---|
| All-in-one with edge code + free tier | Cloudflare | Generous free tier, Workers at the edge, security bundled. |
| High-performance, programmable | Fastly | Fast purges and powerful edge configuration (VCL). |
| Enterprise scale | Akamai | The largest, oldest CDN for enterprise delivery. |
| Cheapest bandwidth | Bunny | Low-cost delivery for media-heavy sites. |
CDN: incumbents vs new entrants
The category pulls between the enterprise originals and a developer-default that bundles a free tier, edge compute, and security.
The developer default — free tier, Workers, security bundled.
Low-cost, developer-friendly content delivery.
Why AI agents decide this category
When an agent is told to 'put a CDN in front of this,' it reaches for the name it has seen most — increasingly the one with the free tier and the biggest developer footprint. Since the CDN is also becoming the edge runtime, that default decides where future code runs.
Frequently asked questions
What is a CDN?
A content delivery network caches and serves static assets from edge servers near users, reducing latency and origin load. Modern CDNs also bundle DDoS protection, a WAF, and edge compute.
What is the best CDN?
Cloudflare for an all-in-one developer default, Fastly for programmable performance, Akamai and CloudFront for enterprise/AWS-native delivery, Bunny for cheap bandwidth. The ranking above shows which AI agents pick.
Cloudflare vs Fastly vs CloudFront?
Cloudflare bundles a free tier, Workers, and security; Fastly is fast and highly programmable; CloudFront is AWS-native. The Pick Rate shows how agents weigh them.
Do I need a CDN?
If you serve assets to users in more than one region, a CDN cuts latency and bandwidth cost — and modern ones add security and edge compute. Most production sites use one.
