Choose a CDN by deciding what it may cache, how an update becomes visible and who owns the origin-to-edge relationship. Cloudflare CDN fits teams using a zone-based proxy and its site plans. Amazon CloudFront offers AWS-connected distributions with both flat-rate and usage-based buying paths. Fastly CDN is a strong shortlist when programmable delivery and rapid cache control matter to the operating team. bunny CDN makes network choice and regional bandwidth costs explicit. CDN77 is relevant to higher-volume delivery programs that justify a larger monthly commitment. A lower advertised price per gigabyte is not a complete delivery decision.
What the buying decision includes
Compare the same cacheable assets, HTML/API behavior, regions, request counts, hostnames and origin traffic. Separate cache delivery from storage, authoritative DNS, image processing and application-security services, even when a package combines them. Identify which responses contain private or personalized data and which changes require invalidation. A CDN cannot safely make all application responses public merely because caching could reduce origin work. Vendor network size and performance examples do not establish which service will be quickest for your audience.
| Service | Operational fit | Commercial model | Check before choosing |
|---|---|---|---|
| Cloudflare CDN | A site proxy with integrated zone controls | Site plan and optional paid capabilities | Default cache behavior versus custom rules |
| Amazon CloudFront | Distribution-based delivery with AWS integration | Flat-rate per distribution or pay-as-you-go | Bundle allowances and required origin/control features |
| Fastly CDN | Programmable delivery and targeted invalidation | Regional bandwidth, requests and related services | TLS, logs and application services in the actual scope |
| bunny CDN | Cost-conscious pull delivery with explicit network choice | Standard regional or Volume global-rate network | Different network footprints, minimum and add-ons |
| CDN77 | Higher-volume delivery with service support | Growth traffic commitment or custom Enterprise | Overages, origin storage and support scope |
Cloudflare CDN
Cloudflare’s cache sits within its proxy service, with rules for cache eligibility and behavior. It is a useful shortlist when the team wants delivery and site controls administered together. Establish which hostnames are proxied, which assets are eligible and how application cache headers should be respected. Do not assume that putting a hostname behind Cloudflare caches every HTML or API response. The origin still needs correct authentication and cache policies for private data.

Cloudflare’s site plans combine delivery with other capabilities, while cache rules and advanced options depend on the selected plan or service. Compare the specific controls, log access, support and any image or storage requirements rather than treating a flat site-plan fee as an unlimited entitlement to every Cloudflare product. For a small public site, the integrated model may simplify operations; a business needing a narrowly defined asset-delivery contract should still inspect the relevant plan terms and content scope before making a bandwidth-cost comparison.

Amazon CloudFront
Amazon CloudFront supports distributions that serve cached objects or forward requests to an origin, including supported AWS and other HTTP origins. It is a practical shortlist when delivery needs to connect with an AWS operating environment. Decide how cache behavior, origin access, certificates and updates will be managed. Storing an object in S3 and delivering it through a correctly configured distribution are separate parts of the application, even when a commercial package bundles several services. Amazon CloudFront official source.
The current pricing page offers flat-rate plans alongside pay-as-you-go pricing. Published monthly prices per distribution include Free, Pro at US$15, Business at US$200 and Premium at US$1,000, with different request allowances and feature entitlements. For example, custom caching rules and private origins within a VPC begin in Business, and origin failover is listed in Premium. The flat-rate page says no overage charges; that does not remove its usage allowances or make all origin services free. Compare the necessary controls, distribution count and allowance terms before applying a legacy per-GB estimate. Amazon CloudFront official source.
Fastly CDN
Fastly provides programmable content delivery, cache control and purging aimed at teams that want to influence how content is served at the edge. It deserves attention when engineers need delivery behavior to follow the application’s publishing model, rather than relying on a fixed cache duration alone. Specify which objects must be refreshed together and how configuration changes are reviewed. Fast invalidation is useful only when the application identifies the right content and keeps personalized responses outside an unsafe shared cache. Fastly CDN official source.
Fastly’s current Full Site Delivery rate card meters bandwidth by region and HTTP requests, with published free allowances and volume bands. TLS domains and related products have their own pricing sections. Price the actual geographic audience, request volume and domain requirements rather than comparing bandwidth alone with a bundled site plan. Additional compute, image processing, logging or security services can change the scope. A team that does not need programmability may prefer a simpler configuration, while a publishing operation with precise invalidation requirements may value the extra control.

bunny CDN
bunny CDN provides pull-based content delivery with cache controls, edge rules and connections to its wider delivery products. It is a useful shortlist for businesses seeking a relatively direct asset-delivery setup. Identify the pull zone, origin, cache key and update process before comparing costs. In particular, decide whether image optimization or storage is a separate requirement; a CDN endpoint and an origin repository perform different jobs even when supplied by the same company. bunny CDN official source.
Its pricing distinguishes the Standard Network, with regional bandwidth rates, from a smaller-footprint Volume Network using a global rate schedule. The page lists no request fees and a US$1 monthly minimum. Those network choices should not be treated as identical service footprints at different prices. Compare the audience regions you need, the selected network and any extra product or support charges. A cheap global Volume rate can be attractive for high-bandwidth assets, but it is not evidence that every visitor will receive the same delivery path as the Standard option. bunny CDN official source.
CDN77
CDN77 supports HTTP object delivery, video-oriented delivery options and cache layers such as request collapsing. Its service-led approach is worth considering when a larger content operation wants delivery and specialist support scoped together. Determine whether the requirement is ordinary assets, live or on-demand media, or dedicated infrastructure, because a general CDN feature list is not the same as an agreed deployment. Network-wide capacity claims do not establish the performance of a specific workload. CDN77 official source.
The current Growth plan lists US$990 per month for 250 TB of traffic, with US$3.96 per TB overage, while Enterprise is tailored. That is a meaningful commitment for a small site, even if the included volume fits a larger publisher well. CDN77 Object Storage is separately priced; the page distinguishes traffic to its CDN from egress outside that delivery path. Compare storage, delivery and support as separate lines before contrasting the Growth commitment with a usage-only CDN. Confirm the contract term and exact media or security scope in the proposal. CDN77 official source.
Which purchase fits your operation?
Choose Cloudflare when its integrated site proxy fits your controls, CloudFront when the required AWS distribution and bundle scope are clear, and Fastly when the team needs programmable publishing behavior. Compare bunny for explicit network and regional bandwidth economics, and CDN77 when the traffic commitment and delivery-support relationship fit. Cache correctness and the commercial unit should lead the decision.
A public download library, a frequently updated publisher and an authenticated application can generate similar transfer totals while needing different cache rules. Count both traffic and requests, map the countries served, and identify the work required to publish or revoke content. If the origin sends poor cache instructions, buying a broader network is unlikely to resolve the underlying problem. Retain a clear owner for cache configuration and distinguish vendor feature claims from actual performance evidence for your own users.
