Picking a CDN in 2026 is less about raw speed than it used to be. All three of these networks will make your site faster than running without one. The real differences show up in pricing models, how much control you get over caching logic, and what happens when something breaks at 3 AM.
Cloudflare is the default choice for most teams: a massive anycast network, a generous free tier, and security features bundled in. Fastly is the engineer’s CDN: fewer points of presence, but each one is a heavyweight, and you get configuration control most CDNs will not give you. Bunny CDN is the budget disruptor: straightforward per-gigabyte pricing and tight integration with its own storage and video products.
This guide compares the three on architecture, pricing, and fit, so you can match the CDN to your workload.
Last updated: October 2026. CDN pricing changes frequently; treat all prices below as approximate and check official pricing pages before committing.
Cloudflare: the network that does everything
Cloudflare’s pitch is simple: put your site behind its network and get CDN, DNS, DDoS protection, and a WAF in one package. The company reports an edge network spanning more than 300 cities, one of the largest CDN footprints you can buy. Every plan, including the free one, runs on the same anycast network, so a blog on the free tier gets the same geographic coverage as an enterprise customer. What differs between plans is features and support, not PoP access.
That architecture shapes the tradeoffs. Cloudflare’s strength is breadth: unmetered DDoS mitigation on every plan, setup that takes minutes, and Workers, its edge compute platform, for running code close to users. The free tier is genuinely useful for small sites, which is why Cloudflare powers a huge share of the web’s long tail.
The tradeoff is control and cost predictability at scale. Cache behavior is managed through page rules and cache rules rather than raw configuration code, which is friendlier but less expressive than Fastly’s model. Entry pricing is simple (a free tier, then Pro at around $20/month and Business at around $200/month as of early 2026), but large-volume customers negotiate enterprise contracts, so published pricing stops telling the whole story once you push serious bandwidth.
Best for: teams that want CDN plus security in one dashboard, small sites that need a free tier that actually works, and anyone building on Workers.
Fastly: the engineer’s CDN
Fastly took the opposite approach from Cloudflare: fewer points of presence, each built for high throughput, and deep configurability through VCL (Varnish Configuration Language) plus Compute@Edge, which runs WebAssembly at the edge. If Cloudflare is a managed platform, Fastly is a toolkit.
The practical payoff is control. You can write custom caching logic, manipulate headers and cookies with precision, and purge content globally in about 150 milliseconds, a figure Fastly markets as instant purging. For teams serving dynamic or personalized content where cache rules get complicated, that control is the reason to pick Fastly.
Pricing reflects the positioning. Fastly bills on usage with request and bandwidth components, and it historically enforced monthly minimums, which made it a poor fit for tiny sites. That has softened over the years, but Fastly still prices like infrastructure for companies with real traffic rather than a free-tier playground. Confirm the current model before committing, because it has changed more than once.
Support quality is a genuine differentiator. Fastly’s support engineers tend to be people who deeply understand the platform, which matters when your caching logic misbehaves in production.
Best for: engineering teams that need custom edge logic, media and commerce sites with complex caching needs, and anyone who values purge speed and configurability over a free tier.
Bunny CDN: the budget disruptor
Bunny CDN (from Bunny.net) entered as the price-performance play and stayed there. The model is disarmingly simple: pay per gigabyte delivered, with regional pricing tiers and no monthly minimums on typical setups. For small and mid-size projects it is often dramatically cheaper than the incumbents, which is the entire pitch.
The network is a budget anycast design with dozens of PoPs worldwide. It will not match Cloudflare’s city count, but for most audiences the difference shows up in tens of milliseconds, not seconds. Where Bunny stands out is product integration: Bunny Storage gives you origin storage in multiple regions, and Bunny Stream handles video transcoding and delivery, so a video-heavy site can run its whole pipeline on one bill.
The tradeoffs are what you would expect at the price. The dashboard and documentation are solid but thinner than Cloudflare’s ecosystem. Security features like a WAF exist, but the depth does not match Cloudflare’s. Support handles standard issues well but is not the white-glove experience Fastly sells.
Best for: cost-sensitive projects, video delivery on a budget, developers who want simple per-gigabyte billing without minimums, and anyone already using Bunny Storage or Stream.
Head-to-head comparison
| Cloudflare | Fastly | Bunny CDN | |
|---|---|---|---|
| Network model | Massive anycast, 300+ cities (per Cloudflare) | Fewer, high-capacity PoPs | Budget anycast, dozens of PoPs |
| Pricing model | Free tier; flat monthly plans; enterprise contracts | Usage-based, historically with minimums | Pay per GB, regional tiers, no minimums |
| Edge compute | Workers (JavaScript/WASM) | Compute@Edge (WASM) | Edge scripting (lighter-weight) |
| Configurability | Rules-based, beginner-friendly | VCL, very expressive | Simple, preset-driven |
| DDoS protection | Unmetered on all plans | Included, enterprise-grade | Basic included |
| Video story | Stream product available | Origin shielding for video origins | Bunny Stream (transcoding + delivery) |
| Standout strength | Breadth + free tier | Control + purge speed | Price + simplicity |
No single row decides the winner. The right pick depends on which column matters most for your workload.
Choosing by workload
Static site or blog. Start with Cloudflare’s free tier. It takes minutes to set up and you may never need to pay. Bunny is the backup pick if you outgrow free and want cheap bandwidth.
Video streaming. Bunny Stream is hard to beat on price for transcoding plus delivery. Fastly works well as an origin shield in front of your own video origin when you need fine-grained control.
API acceleration and dynamic content. Fastly’s configurability and fast purging help when responses cannot sit in cache for hours. Cloudflare’s cache rules plus Workers cover most of the same ground with less custom code.
E-commerce. Cloudflare’s WAF and bot management bundle security with speed, which matters when you are a target. Fastly fits if your team wants to hand-tune caching around carts and personalization.
Edge compute. Compare Workers and Compute@Edge on language support and pricing for your specific workload. Both are serious platforms; Bunny’s scripting covers lighter use cases.
Frequently asked questions
Is Bunny CDN reliable enough for production?
Yes, for most workloads. It serves significant traffic across its customer base. The honest caveat: if you need contractual SLAs, dedicated support engineers, or advanced compliance certifications, the enterprise tiers of Cloudflare or Fastly are the safer bet.
Does Cloudflare’s free plan slow down my site?
No. Free-tier traffic runs on the same anycast network as paid plans. The limits show up in features (fewer page rules, no advanced WAF rules), not in speed.
Why does Fastly cost more for small sites?
Its pricing model targets real traffic volumes rather than hobby projects. The value appears in configurability, purge speed, and support quality, which matter more as you scale. For a side project, Cloudflare’s free tier or Bunny’s per-GB billing will almost always be cheaper.
Can I switch CDNs later?
Yes, and it is routine. Keep your DNS TTLs low during migration, run both in parallel briefly if downtime is unacceptable, and test cache behavior before cutting over. Most teams can migrate a standard site in an afternoon.
The bottom line
There is no best CDN, only the best fit. Cloudflare wins on breadth and the free tier. Fastly wins on control. Bunny wins on price. Match the network to the workload, start simple, and remember that migrating later is normal. The expensive mistake is over-engineering the choice for traffic you do not have yet.
