If you want a complete free layer in front of your site (CDN, DNS, WAF, DDoS protection and SSL) without paying anything to start, Cloudflare wins: its free plan more than covers a corporate site, a WordPress install or an SMB. If what you need is a pure CDN that's very cheap per GB, with fine cache control and image and video tools at competitive prices, Bunny CDN is the better choice. And the best part: for many projects the optimal answer is using both at once — Cloudflare for security and DNS, Bunny to serve heavy media cheaply.
A CDN (content delivery network) stores copies of your site on servers spread around the world so each visitor gets the files from the nearest point, reducing latency and origin-server load. Cloudflare and Bunny CDN are two of the most popular options, but they follow different philosophies: Cloudflare is a complete performance and security platform with a very generous free plan; Bunny CDN is a pure pay-as-you-go CDN, known for its rock-bottom price per GB and fine cache control. In this head-to-head we pit them on what really decides the choice: price, performance, server network, security and media tools.
The underlying difference is in model and scope. Cloudflare gives you DNS, SSL, WAF, DDoS protection and CDN free in a single panel; Bunny focuses on moving bytes as cheaply and fast as possible, with image extras (Bunny Optimizer) and video (Bunny Stream) at very competitive prices. Let's break it down so you can choose wisely based on project type, traffic and budget.
| Criterion | Cloudflare | Bunny CDN |
|---|---|---|
| Service type | CDN + security + DNS platform | Pure pay-as-you-go CDN |
| Free plan | Yes, very complete (CDN/DNS/SSL/DDoS) | No (per GB, ~10 USD minimum balance) |
| Price | Free; Pro/Business plans; extras separate | From ~0.01 USD/GB by region |
| Server network (PoPs) | Huge, hundreds of cities | Broad and high performance |
| Managed DNS | Yes, fast and included | No (handled by your provider) |
| WAF and DDoS protection | Yes, included (unlimited DDoS) | Basic; CDN focus |
| Image optimization | Polish / Image Resizing (paid) | Bunny Optimizer (cheap) |
| Video streaming | Cloudflare Stream (paid) | Bunny Stream (very competitive) |
| Cache control | Good (Page Rules / rules) | Very fine (Perma-Cache, edge rules) |
| Ease of use | DNS switch, full panel | Pull zones, simple curve |
| Best for | Site/WordPress with free security and speed | Serving many files, images or video cheaply |
| Rating | ★★★★★ 4.7/5 | ★★★★★ 4.6/5 |

This is one of the keys. Cloudflare plays the free-plan card: CDN, DNS, SSL, unlimited DDoS protection and basic rules at no cost, which more than covers most personal sites, blogs, WordPress installs and SMBs. When you need advanced features (Argo Smart Routing, Load Balancing, Image Resizing, R2 storage or the full managed WAF), you move to Pro/Business plans or pay for those extras separately, and that's where the bill can grow depending on usage.
Bunny CDN bets on pay-as-you-go: it charges per GB transferred (from roughly 0.01 USD/GB depending on region) with no high fixed fee, although it usually asks for a minimum top-up balance (around 10 USD) to start. For projects that serve lots of heavy files, images or video, this model is very cheap and, above all, predictable: you pay exactly for what you move. If your site is light, free Cloudflare is unbeatable; if you move a lot of media bandwidth, Bunny usually comes out cheaper than Cloudflare's paid extras.

Both are very fast. Cloudflare has one of the largest networks on the planet, with presence in hundreds of cities, giving it excellent latency almost anywhere and global-scale DDoS protection. Bunny CDN also has a broad network and very good performance, with the advantage of very fine cache control (Perma-Cache to keep content always at the edge, per-zone rules, precise purges). In real tests, for a normal site the speed difference between the two is usually small: the proximity of PoPs to your audience and a good cache setup matter more than the brand you pick.
Cloudflare is much more than a CDN: it includes fast managed DNS, WAF, DDoS protection, universal SSL, Workers (edge computing) and a huge ecosystem. It's the natural choice if you want integrated security and performance in a single panel without adding providers. Its image optimization (Polish, Image Resizing) and streaming (Cloudflare Stream) exist but are paid separately.
Bunny CDN shines in media: its Bunny Optimizer compresses and serves images in WebP/AVIF on the fly at minimal cost, and Bunny Stream offers video hosting and playback at very competitive prices versus alternatives like Cloudflare Stream or Vimeo. If your project lives on serving images or heavy video (galleries, e-commerce with many photos, video courses), Bunny gives you cheap specialized tools. For a store, pair it with good WooCommerce hosting and check our Webempresa vs Raiola comparison.
Cloudflare is the most used performance and security platform on the Internet. Its biggest strength is the free plan, which already includes CDN, DNS, SSL and enterprise-grade DDoS protection, and its giant global network. It's the comfortable choice for putting a layer of speed and security in front of any site at no cost and without hassle, with room to grow into Workers, R2 and the advanced WAF when you need them.
Bunny CDN is the pay-as-you-go CDN favored by those who want a very low price per GB and control. Its biggest strength is the combination of cheap, predictable pricing, very fine cache control (Perma-Cache, edge rules) and specialized media tools: Bunny Optimizer for images and Bunny Stream for video. It's the ideal pick when you move a lot of file bandwidth or want to serve optimized images and video without blowing up the bill.

Choose Cloudflare if you want a free speed and security layer in front of your site, you benefit from having DNS, SSL, WAF and DDoS protection in one place, and your traffic is mostly pages (corporate site, blog, WordPress, SMB). Choose Bunny CDN if your project moves a lot of media bandwidth (images, downloads, video) and you want the lowest, most predictable per-GB cost, with specialized tools like Optimizer and Stream. And don't forget the third path: for many projects the optimal setup is combining both — Cloudflare for free DNS, SSL and security, and Bunny to serve heavy media cheaply.
