Two of the mid-market’s favorite pay-as-you-go CDNs, compared where it counts: rate cards, hidden line items and what each network is actually built for.
Winner depends on your workload.
Winner depends on: your traffic volume and geography, whether you need add-ons KeyCDN meters separately (logs, extra zones, image ops), and how much the surrounding platform — storage, video, edge rules — matters to you.

| Other regions | $0.03–$0.06/GB by region (Standard) | Asia $0.08/GB; Africa/LatAm $0.10/GB |
| Minimum | $1/month | $4/month usage; $49 minimum top-up |
| Requests | Not billed | Not billed |
| Metered extras | Optimizer $9.50/site; storage $0.01/GB | 4th+ zone $1/mo; push storage $0.12/GB/mo; logs $1/day; image ops $0.40/1k |
| Network | 119 PoPs (Standard), 10 high-capacity (Volume) | 60+ PoPs, zone-selectable |
| Platform extras | Storage, Stream, Shield, Edge Scripting, DNS | Delivery-focused; image processing add-on |
Same model, different decade
Both networks sell the same promise — transparent per-GB pricing, no contract, all features on every account — and both earned loyal followings doing it. The difference is trajectory. KeyCDN, the Swiss veteran, has kept its product tightly delivery-shaped: pull zones, instant purge, free SSL, a clean API, and a rate card that has barely moved in years. Bunny, from Slovenia, kept the pricing ethos and built outward: edge storage with free internal transfer to the CDN, a video platform, image optimization, DNS, a WAF layer, and edge scripting. One stayed a CDN; the other became a small edge platform with a CDN at its center.
The rate cards, side by side
On headline NA/EU rates Bunny starts at a quarter of KeyCDN’s price: $0.01/GB on the Standard network against KeyCDN’s $0.04/GB opening tier. KeyCDN clawbacks arrive with volume — $0.03 after 10 TB, $0.02 after 50, and $0.01 beyond 100 TB — while Bunny’s Volume network undercuts again at a flat $0.005/GB worldwide for the first 500 TB, served from a smaller ten-PoP footprint tuned for large files. Outside NA/EU the gap widens: KeyCDN bills Asia at $0.08/GB and Africa/Latin America at $0.10/GB, where Bunny’s Standard regions run $0.03–$0.06.
Worked example at 20 TB/month, 80% NA/EU, 20% Asia: Bunny Standard ≈ 16,000×$0.01 + 4,000×$0.03 = $280. KeyCDN ≈ (10,000×$0.04 + 6,000×$0.03) + 4,000×$0.08 = $900. At 150 TB nearly all NA/EU the gap narrows — KeyCDN’s blended rate falls toward $0.02/GB — but Bunny’s Volume tier at $0.005 keeps the multiple. Figures checked against provider pricing pages, July 2026.
The line items that surprise people
KeyCDN’s simplicity has edges. The first three zones are free, then $1/month each; push-zone storage runs $0.12/GB per month; raw log forwarding costs $1/day; image processing bills $0.40 per thousand operations; and topping up credit has a $49 minimum. None of these is unreasonable, but observability-minded teams and multi-property estates should price them in. Bunny’s equivalents mostly fold into the platform — storage at $0.01/GB with free egress to the CDN, logging included — with the Optimizer at $9.50 per site the main paid add-on.
Where KeyCDN still earns the shortlist
Three places. Teams that want a deliberately small, stable surface — no platform sprawl, a rate card that hasn’t surprised anyone in years — find that conservatism a feature. The zone-selection model lets a regional business disable expensive geographies cleanly. And its instant purge and simple API remain genuinely good; this is a network that does one job and has done it reliably since long before the current budget-CDN wave — a wave we covered from another angle in KeyCDN vs BelugaCDN.
How to decide
Price is not really the open question — Bunny wins the arithmetic in almost every profile, as it does against most of the field in Gcore vs Bunny. The real question is whether you want the platform. If your roadmap touches video, storage-backed delivery or image optimization, Bunny consolidates line items you would otherwise buy separately. If you want a plain, proven pull CDN with Swiss-watch predictability and your volumes sit in KeyCDN’s cheaper tiers, the veteran still deserves its slot — especially as a low-risk second leg in a multi-CDN pair.
