Bunny CDN vs Cloudflare vs KeyCDN 2026: Which One Wins for Multi-Site Operations?

I run 7 aggregator sites on Hostinger shared hosting plus a VPS that hosts the heavier workloads. Across the lot, I push roughly 280 GB of bandwidth per month — half of which is static assets like article images, CSS, JS bundles, and the occasional PDF download. After eleven years of building production systems and shipping 50+ projects through Warung Digital Teknologi, I have used every major CDN at one point or another. In April 2026 I sat down and ran a head-to-head between Bunny CDN, Cloudflare, and KeyCDN specifically for multi-site operations. The results changed how I price my hosting stack.

This is not a generic best-CDN-of-2026 piece. I am writing this from the perspective of someone who actually pays the bills for content delivery across several WordPress and custom Laravel sites. If you are running a single small blog, the answer is almost always "use Cloudflare's free plan and stop reading." If you are running anything where you need fine-grained control over caching, predictable pricing, or per-zone settings without paying enterprise prices, keep reading.

TL;DR — Which CDN Wins for Multi-Site in 2026?

Short version after testing all three across my 7 sites for 30 days:

• Cloudflare Free — best for sites under 100 GB/month with simple caching needs. Unmetered bandwidth on Free, Pro, and Business plans, but cache rules are limited and image optimization is gated behind paid tiers.
• Bunny CDN — winner for predictable pay-as-you-go billing. $0.01/GB in North America/Europe, drops to $0.005/GB at volume tier (first 500 TB). Per-zone control is excellent for multi-site setups.
• KeyCDN — solid middle ground at $0.01–$0.04/GB depending on region, with a $4 starter plan and 14-day trial. Cache hit ratio reporting is the cleanest of the three.

The right choice depends on your traffic shape, regional distribution, and how much per-site control you actually need. I will walk through the actual numbers from my setup.

My Test Setup: 7 Sites, 30 Days, Real Bandwidth

I run the following sites simultaneously, all served from a Hostinger shared plan with a Cloudflare account in front of most of them:

• HireVane (jobs aggregator) — ~80 GB/month static asset traffic
• HoroAura (horoscope content) — ~45 GB/month
• QuickExam (test prep articles) — ~40 GB/month
• HealthSavvyGuide (health content) — ~35 GB/month
• FinanceTrackDaily (finance content) — ~30 GB/month
• CloudHostReview (you are reading this) — ~28 GB/month
• CyberShieldTips (security content) — ~22 GB/month

For the test I picked three sites and routed each through a different CDN: HireVane on Cloudflare Free, HoroAura on Bunny CDN Standard tier, and QuickExam on KeyCDN starter plan. Same content type, same hosting backend, same caching headers from origin. I let them run for 30 days and pulled metrics on cache hit ratio, time to first byte (TTFB), monthly cost, and operational headaches.

Pricing in 2026: The Real Math

Cloudflare

Cloudflare's free plan still includes unmetered bandwidth across 330+ data centers, free Universal SSL, basic WAF, and DDoS mitigation. The catch in 2026 is that the free plan caps you at 5 page rules total and gives you no Cache Analytics. If you want custom WAF rules, image optimization with Polish, or proper cache analytics, you need Pro at $25/month per zone — and per-zone is the killer for multi-site operators. Seven sites on Pro is $175/month.

The Pro plan adds Polish image optimization, 20 page rules, and Cache Analytics. Business at $250/month adds custom SSL, Argo Smart Routing, and 50 page rules. Enterprise pricing is custom and starts well above what most multi-site operators want to pay.

Important update for 2026: Mirage (Cloudflare's mobile image optimization) was deprecated in late 2025 and is no longer available on any plan. If you depended on Mirage for mobile bandwidth savings, you now need to use Polish (Pro+) or move image optimization elsewhere.

Bunny CDN

Bunny's pay-as-you-go model is what drew me in. The pricing is published openly:

• North America & Europe: $0.01/GB (Standard tier with 3 replication points), $0.005/GB on Volume tier (first 500 TB)
• Asia & Oceania: $0.03/GB Standard, $0.025/GB Volume
• South America: $0.045/GB Standard
• Africa & Middle East: $0.06/GB Standard
• Minimum monthly fee: $1

For my 280 GB/month spread across mostly North America and Europe, that works out to roughly $2.80/month if I funnel all 7 sites through Bunny. At petabyte scale Bunny drops to $0.002/GB, which is why I see large media sites moving to it.

KeyCDN

KeyCDN sits between the two. Their starter is $4/month for 50 GB of credit, then $0.04/GB above. Volume tiers drop pricing to $0.01/GB once you scale past 10 TB. Regional pricing exists but the spread is narrower than Bunny's — North America and Europe are $0.04/GB, Asia is $0.07/GB. If you stay under 50 GB/month per zone the starter plan is the cheapest of the three for tiny sites.

The 14-day free trial gave me 250 GB of bandwidth credit, which was enough to actually test the platform under real traffic — a refreshing change from the "demo zone with synthetic load" approach most providers offer.

Cache Hit Ratio: The Number That Actually Matters

Pricing is one thing. Cache hit ratio (CHR) determines whether your CDN is doing its job. Every cache miss means your origin server eats the request, which on shared hosting means your TTFB goes from 30–60 ms to 400–800 ms. After 30 days of real traffic, here is what I measured:

• Cloudflare Free (HireVane): 71% CHR. The big problem is that Cache Analytics is locked on Free, so I had to estimate this from origin logs. Without proper cache rules I could only cache static assets via the default behavior — HTML pages all went to origin every time.
• Bunny CDN (HoroAura): 89% CHR with Perma-Cache enabled and origin shield turned on. Their Edge Rules let me cache HTML for short TTLs (5 minutes) on article pages while keeping admin URLs uncached. Took about 20 minutes to configure correctly.
• KeyCDN (QuickExam): 84% CHR. Their dashboard reports CHR clearly under each pull zone, which made tuning straightforward. I added a custom cache rule for /article/* paths and watched the ratio climb from 62% to 84% over a few hours.

The Cloudflare CHR number is misleading — it would be much higher if I could write custom cache rules, but that requires Pro at $25/month per zone. Multiplied across 7 sites, that is real money for a feature that Bunny and KeyCDN include by default.

TTFB and Real-World Speed

I measured TTFB from 5 locations (Frankfurt, New York, Singapore, São Paulo, Sydney) using GTmetrix and WebPageTest, averaged over 100 runs per site:

Location	Cloudflare Free	Bunny CDN	KeyCDN
Frankfurt	38 ms	22 ms	31 ms
New York	41 ms	28 ms	34 ms
Singapore	62 ms	49 ms	87 ms
São Paulo	78 ms	71 ms	112 ms
Sydney	71 ms	58 ms	96 ms

Bunny CDN won every region except São Paulo where it was within 10% of Cloudflare. KeyCDN trailed in Asia and South America, which lines up with their thinner PoP network in those regions. Cloudflare's global anycast network is genuinely impressive on Free, but Bunny's per-region tuning gave it the edge on cached content delivery.

Multi-Site Setup Experience

Setting Up 7 Sites on Cloudflare

Cloudflare treats each domain as a "zone." On Free you can add unlimited zones, which is great. But every zone shares the same 5-page-rule limit individually. So my 7 zones gave me 35 page rules total, but I could not centrally manage caching policy across all of them. Workers and Cache Rules can fix this on Pro+, but again that is per-zone billing.

The DNS management is excellent — I have used Cloudflare DNS for years and never had a propagation issue. SSL provisioning is automatic. The dashboard is clean. For someone running multiple small sites who does not need fancy caching, Cloudflare Free remains hard to beat.

Setting Up 7 Sites on Bunny CDN

Bunny uses "Pull Zones" — each zone connects to one origin and gets a unique CDN URL like cdn-yoursite.b-cdn.net which you CNAME from a subdomain. Setting up a single pull zone takes about 3 minutes including DNS verification. I scripted the setup for the remaining 6 sites using their REST API:

curl -X POST 'https://api.bunny.net/pullzone' \
  -H 'AccessKey: YOUR_KEY' \
  -H 'Content-Type: application/json' \
  -d '{"Name":"hirevane","OriginUrl":"https://hirevane.com","StorageZoneId":0,"Type":0}'

What I really like is per-zone Edge Rules. I can configure aggressive caching on aggregator article pages, no caching on admin URLs, and image optimization on /uploads/* — all without touching another zone's settings. This isolation matters when you are debugging one site and do not want to break the others.

Setting Up 7 Sites on KeyCDN

KeyCDN's pull zones work similarly to Bunny's. The dashboard groups everything under one account, billing is consolidated, and zone-level cache rules are available without paying extra. The signup-to-first-zone time was about 8 minutes.

The catch: KeyCDN does not have built-in image optimization. You can use their "Image Processing" add-on at extra cost, or pipe images through a separate service like ImageKit before serving from KeyCDN. For my use case (where 60% of bandwidth is article images), this was a deal-breaker for going all-in on KeyCDN.

Image Optimization: Where the Money Actually Lives

Across my 7 sites, images account for roughly 60% of monthly bandwidth — that is around 168 GB/month. Cutting this number directly reduces my CDN bill, my origin transfer, and my page weight. Here is what each provider offers in 2026:

• Cloudflare: Polish (Pro+) does lossy/lossless compression and WebP/AVIF conversion on the fly. Cloudflare Images is a separate paid product that bundles storage + transformations at $5/month for 100k stored images.
• Bunny: Bunny Optimizer is included, you just enable it per pull zone. It does WebP/AVIF auto-negotiation, on-the-fly resizing via URL parameters (?width=800), and quality adjustment. Costs $9.50/month per pull zone with the Optimizer add-on, or you can use Bunny's free basic image processing.
• KeyCDN: No native image optimization. Use a separate service.

I tested Bunny Optimizer on HoroAura's article images. Average reduction was 47% on JPEGs converted to AVIF, with no visible quality loss at quality=80. That alone would save me roughly 79 GB/month on that one site if I rolled it out — paying for itself many times over.

DNS, Security, and the Stuff Everyone Forgets

CDN is only one piece of the stack. Here is how the three compare on adjacent features:

DNS

Cloudflare DNS is the gold standard. Free, anycast, fast propagation, full DNSSEC support. Bunny DNS is excellent and cheap ($0.40 per million queries) with anycast and a clean API. KeyCDN does not provide DNS — you bring your own.

WAF and DDoS

Cloudflare's free DDoS mitigation is the reason most small operators stick with them. Bunny added Bunny Shield in 2024, which provides DDoS protection and basic WAF rules at $9.50/month per pull zone. KeyCDN has no native WAF.

Logs and Analytics

This is where the gap really shows on Free Cloudflare. You get basic analytics but no raw logs and no Cache Analytics. Bunny provides full request logs (downloadable, 3-day retention on Standard) and real-time stats per pull zone. KeyCDN gives 7-day raw log retention and a clear CHR breakdown.

For debugging cache misses, Bunny and KeyCDN are dramatically more useful than Cloudflare Free. If you want this on Cloudflare you need Logpush, which requires Enterprise.

When to Pick Which: My Decision Matrix

After 30 days of running real traffic through all three, here is how I would split workloads in 2026:

• Pick Cloudflare Free if: You run 1–3 small sites under 100 GB/month total, you do not need granular cache rules, and DDoS protection is your top priority. The price (free) is unbeatable for this profile.
• Pick Bunny CDN if: You run multiple sites, you want predictable per-GB billing, you need image optimization without paying enterprise rates, and you want full per-zone control. This is what I am moving most of my static traffic to.
• Pick KeyCDN if: You want simple, transparent CDN with great cache reporting and you handle image optimization separately. Their starter plan is good for tiny zones, but they fall behind Bunny on price and image features at scale.

What I Actually Run Now

Since the test, I have settled on a hybrid setup:

• Cloudflare Free sits in front of all 7 domains for DNS, SSL, and DDoS mitigation — turned to "DNS only" mode (gray cloud) for static asset hostnames.
• Bunny CDN serves all images via cdn.[domain].com pull zones, with Bunny Optimizer enabled. Estimated monthly cost across all 7 sites: $4–6.
• Origin (Hostinger shared) serves dynamic HTML directly through Cloudflare's CDN with default caching.

The combined monthly bill: about $5/month for Bunny + $0 for Cloudflare. Compare that to running everything on Cloudflare Pro at $175/month for 7 zones, and you can see why I stopped paying for Pro plans on aggregator sites a long time ago.

The Mistakes I Made So You Do Not Have To

Three things I wish someone had told me before I started:

1. Do not put Bunny behind Cloudflare's orange cloud. If both proxies are active, you get double-CDN behavior and weird cache invalidation. Use Cloudflare in DNS-only mode for the cdn subdomain that points to your Bunny pull zone.
2. Set proper Cache-Control headers at origin. All three CDNs respect origin cache headers by default. If your WordPress or Laravel app is sending Cache-Control: no-store on every static asset, none of these CDNs will cache anything. Fix this before blaming the CDN.
3. Test image optimization quality before flipping it on globally. Bunny Optimizer at quality=80 was fine for my photos, but reduced quality on some screenshots with text. I now run quality=85 for /article/* paths and quality=75 for thumbnails.

FAQ

Is Cloudflare really free with no catches?

Mostly yes for typical website traffic. The catch is the Terms of Service language about "disproportionate non-HTML content" — if you serve large amounts of video or files, Cloudflare will eventually email you about moving to Stream or R2. For a normal blog or aggregator site, Free works indefinitely.

Does Bunny CDN have a free trial?

Bunny gives you $1 in free credits to test, plus their pricing is so cheap that running a real test workload typically costs under $0.50. I would not call it a free trial in the marketing sense, but the cost barrier is effectively zero.

Can I use both Bunny and Cloudflare?

Yes, and this is what I recommend for multi-site setups. Use Cloudflare for DNS and DDoS protection on your apex domain, then use Bunny for actual content delivery via a CNAMEd cdn subdomain. Set Cloudflare to DNS-only mode for that subdomain so requests go directly to Bunny.

Why not just use AWS CloudFront?

CloudFront makes sense if you are already deep in the AWS ecosystem. For independent operators running aggregator sites, CloudFront's pricing complexity and console UX make Bunny's flat $0.01/GB hard to beat. I have used CloudFront for client projects but never for my own sites.

What about Fastly or Cachefly?

Both are excellent for enterprise workloads. Fastly's VCL configuration is the most powerful caching engine available, but the minimum spend ($50/month) and the learning curve put it outside this comparison's scope. For multi-site indie operators, Bunny is the better fit.

Final Verdict

For multi-site operators in 2026, Bunny CDN is the best CDN to actually pay for, Cloudflare Free is the best CDN to add in front of it, and KeyCDN is the best CDN to keep in mind if Bunny ever stumbles. None of these providers is bad — they are optimized for different traffic shapes.

If I had to recommend one provider for someone running 5+ small to medium sites on shared hosting, Bunny CDN wins on price, performance, and per-zone flexibility. If you are running a single small blog and you do not want to think about CDN ever again, Cloudflare Free is fine and will probably stay fine forever. The middle ground (KeyCDN) is real but narrowing as Bunny's feature set keeps expanding.

Whatever you pick, measure cache hit ratio first, then TTFB, then total cost. Most "my CDN is slow" complaints I see in our Discord are actually cache misses caused by bad origin headers — and no CDN can fix that for you.
