Best Content Delivery Network (CDN) Software

Cloudflare operates a global network that provides content delivery, DNS, DDoS mitigation, and a web application firewall to protect and speed up websites and applications. It runs the public 1.1.1.1 DNS resolver and offers unmetered DDoS protection, SSL/TLS encryption, and bot management on every plan, including the free tier.

Beyond its core website plans, Cloudflare sells a large catalog of usage-priced developer products such as Workers, R2 storage, and Zero Trust network access. Paid plans add performance features, compliance reporting, and uptime SLAs, scaling from small sites to large enterprises with custom contracts.

Akamai API Security, formerly Noname Security, is a platform-agnostic solution that discovers, tests, detects and responds to API threats across hybrid, SaaS and on-premises environments. It automatically inventories shadow, zombie and AI-related APIs, covers the OWASP API Security Top 10, runs over 200 dynamic tests to simulate malicious traffic before production, and integrates with WAFs, SIEMs and ITSM tools for automated remediation workflows. The platform does not require Akamai's CDN and works across multiple third-party CDNs, WAFs and gateways.

Akamai completed its acquisition of Noname Security in June 2024 for approximately 450 million dollars, and the product now operates under the Akamai brand. Pricing is not publicly published; Akamai uses a consumption-based enterprise model priced on API call volume, number of monitored environments and optional managed SOC services, quoted through direct sales.

Imperva is an enterprise cybersecurity vendor providing web application firewall, DDoS protection, API security, bot management, and data security products for large organizations. Its Data Security Fabric spans three tiers, Data Assure, Data Secure, and Data 360, covering data discovery, classification, compliance reporting, and threat detection across cloud and on-premises environments.

Imperva does not publish fixed prices; every plan requires contacting sales for a custom quote based on traffic volume, number of applications, and required features. It serves mid-size to large enterprises and is now owned by Thales, though it continues to operate under the Imperva brand.

EdgeNext delivers CDN, cloud security and edge computing optimised for emerging markets, and that focus is the reason to consider it rather than a general-purpose alternative. Most CDN networks are densest in North America and Western Europe, where the commercial traffic has historically been. A provider that has built deliberately for the next wave of global growth is making a different bet, and for a business serving audiences outside the established markets, point-of-presence density where your users actually are matters far more than a provider's total count.

The published network figures are specific: more than 1,500 global points of presence, over 90 Tbps of network capacity, more than 170 partner internet service providers, and a 30 millisecond global response time. The ISP partnership count is the interesting one, since in emerging markets delivery performance depends heavily on peering arrangements with local carriers rather than on edge hardware alone.

Video is a clear priority. A dedicated live streaming solution is published for the 2026 World Cup, covering match-day traffic with low-latency playback, 4K and 8K streaming, DRM, SCTE-35 ad insertion, replay and global edge delivery. SCTE-35 support signals genuine broadcast capability rather than generic video hosting, since it is the standard used for ad insertion in live streams. Media processing covers live signal handling, media recoding and media delivery.

Security is built in, with protection from DDoS and other threats, and the vendor reports blocking more than 60 million threats daily. A network status page and events feed are published openly, which is a good sign for operational transparency. Sign-up is available directly with a free start, and pricing is not published.

Azure Front Door is Microsoft's modern cloud content delivery network, delivering static and dynamic content at low latency and high throughput from cloud or on-premises origins. What distinguishes it technically is the underlying network: delivery runs on Microsoft's massively scalable private global network rather than traversing the public internet between edge and origin, which is where much of the latency variability in content delivery comes from.

Security is genuinely built in rather than attached. A web application firewall, bot protection and DDoS protection are all part of the service, and Azure Private Link support allows the application origin to be reached privately in line with a zero trust model. Real-time analytics cover both traffic and security monitoring together. For organisations that would otherwise buy a CDN and a WAF separately and integrate them, consolidating both is a meaningful simplification as well as a cost question.

The service is fully programmable and API-driven, integrated with Azure DNS, Azure Web Apps and a wide range of other Azure services, so deployment can be automated alongside the rest of an Azure estate rather than configured by hand. Automated deployment is called out as a distinct capability.

Microsoft makes a specific commercial claim worth verifying against your own traffic: pricing is described as simple, easy and transparent, with no additional charges for transferring data from an Azure datacentre to an Azure Front Door edge location. That is the same structural advantage CloudFront offers within AWS, and for an application already hosted in Azure it usually matters more than the headline per-gigabyte rate. New Azure accounts include a 200 dollar credit, and pay-as-you-go rates apply thereafter.

Google offers two distinct content delivery networks, and knowing which one applies is the first thing to establish. Cloud CDN accelerates web applications using Google's global edge network. Media CDN is separate and uses YouTube's infrastructure to deliver video streams, both on-demand and live, along with large file downloads. They solve different problems, and the video-heavy case is served by the second rather than by a configuration of the first.

The Media CDN point is the genuinely distinctive one in this category. YouTube's delivery infrastructure exists because Google had to solve video distribution at a scale nobody else operates at, and offering that same infrastructure commercially is a different proposition from a general-purpose CDN with video features added. For a business whose costs are dominated by streaming, that provenance is worth investigating specifically.

Cloud CDN's own claim is straightforward: it uses the same network that serves 2 billion Google users. Google frames the offering around a decade of experience delivering content, scaling to bring content closer to a global audience. Both products integrate with the wider Google Cloud platform, and a documented pattern exists for building and running dynamic websites using Cloud Run together with Cloud CDN, available as a preconfigured solution to try free.

Commercially, new Google Cloud customers receive 300 dollars in free credits to try Cloud CDN alongside other products, which is enough to run a genuine evaluation rather than a demonstration. Note that this is a platform credit rather than a CDN price: the underlying rates are usage-based within Google Cloud billing, so model expected traffic against the published Cloud CDN rate card before committing.

Amazon CloudFront is AWS's content delivery network, delivering content with low latency and high transfer speeds through more than 750 globally dispersed points of presence, using automated network mapping and intelligent routing. Its decisive commercial characteristic is not the network size but the billing: there are zero fees for data transfer out from AWS origins. For anything already hosted on AWS, that removes the egress charge which usually dominates the cost of serving content, and it is the reason CloudFront is frequently the default rather than a considered choice.

Security is included rather than sold separately at the base level. Traffic encryption, access controls and VPC origins are supported, and AWS Shield Standard defends against DDoS attacks at no additional charge. VPC origins are worth noting, since they allow an origin to stay private rather than being exposed publicly for the CDN to reach.

Edge programmability is available through serverless compute features, letting code run at the CDN edge to balance cost, performance and security. The named use cases show the breadth. Fast, secure websites use built-in data compression, edge compute and field-level encryption. Dynamic content and API delivery is supported with edge termination, gRPC and WebSockets, which matters because many CDNs handle static assets well and dynamic traffic poorly. Live and on-demand video integrates with AWS Media Services and AWS Elemental. Software, game patch and IoT over-the-air update distribution scales automatically at high transfer rates. Getting started material includes a guide, hands-on tutorial and Immersion Days training. Pricing has customisable options and consolidated request billing, though the pricing page was not directly retrievable here.

KeyCDN is a high performance content delivery network whose distinguishing decision is that every account, large or small, has access to all of its features. That removes the usual CDN frustration where HTTP/2, modern TLS or compression sit behind an enterprise tier, and a small site pays for a service deliberately missing the capabilities that make it fast. Named features available to all accounts include HTTP/2, Brotli compression and TLS 1.3.

The infrastructure claims are specific rather than vague. Each edge server is described as built with an advanced TCP stack and 100 percent SSD coverage. The network uses IP anycast with latency-based routing, which is what determines whether a user is actually served from a nearby location rather than a nominally regional one. Published figures are six continents served, 146,031 zones deployed and a 98 percent cache hit ratio, the last being the number that matters most, since a CDN that misses cache is just an extra network hop.

Setup is deliberately short: create a zone by adding a domain, optionally configure advanced customisations or a custom subdomain, then integrate with any CMS, framework or custom application. No credit card is required to start, which combined with pay-as-you-go pricing makes it practical to test with real traffic rather than in theory. Beyond delivery, solutions cover website acceleration, image processing, video and streaming, and cloud storage. Pricing is tiered by monthly volume and published in full, and it falls steeply with usage: North America and Europe run from 4 cents per gigabyte down to 1 cent above 100 terabytes, with Asia and Oceania starting at 8 cents.

Fastly describes itself as a programmable edge cloud platform rather than a content delivery network, and the distinction is real. Its central property is that the platform is fully programmable, meaning logic runs at the edge rather than configuration merely being adjusted there. For teams that want to make routing, personalisation or security decisions close to the user, that is a different proposition from a CDN that caches what it is given.

The analyst recognition it publishes reflects that positioning across several categories rather than delivery alone: named a Leader in The Forrester Wave for Edge Development Platforms in Q1 2026, a Leader in the IDC MarketScape for Worldwide Edge Delivery Services, a Customers' Choice in the 2026 Gartner Peer Insights Voice of the Customer for Edge Distribution Platforms, and a Customers' Choice for Web Application and API Protection. That last one matters, since security is a substantial part of what edge platforms now sell.

Pricing is published as regional bandwidth tiers and is notably generous at the entry point: the first 100 GB per month is free across all listed regions, which is enough for a small site or a development project to run at no cost. Beyond that, rates run from 12 cents to 28 cents per gigabyte for 100 GB to 10 TB depending on region, falling as volume rises. North America and Europe are at the lower end, with Asia-Pacific regions including South Korea at the higher end. Note this is materially more expensive per gigabyte than budget CDNs, which is the trade for programmability and support. A free trial is available, the site is published in six languages, and an emergency under-attack line is staffed for active incidents.

Bunny.net competes on price and simplicity rather than enterprise breadth, and the numbers make that concrete. Bandwidth starts at 1 cent per gigabyte in Europe and North America, with a 1 dollar monthly minimum, on a straightforward pay-as-you-go basis with no commitment. For a small site or an independent developer, that is an order of magnitude below enterprise CDN pricing, and it is the reason the service exists in this form.

Pricing is region-based, which matters when estimating a real bill. Europe and North America are 1 cent per gigabyte, Asia and Oceania 3 cents, South America 4.5 cents, and the Middle East and Africa 6 cents. A site with mostly European traffic and one with mostly African traffic will pay very differently for the same volume, so audience geography should drive the estimate rather than total bandwidth alone.

What has grown around the CDN is a full edge platform, each part priced separately. Bunny Storage is positioned as fast cloud storage with SSD backing. Bunny Stream handles video delivery with a media player, enterprise multi-DRM, premium encoding and AI transcription. Bunny Optimizer does dynamic image processing and optimisation. Bunny DNS covers routing, Bunny Shield covers security, and Bunny Fonts offers privacy-oriented font hosting as a self-hosted alternative to third-party font services. Magic Containers deploy applications globally, Edge Scripting runs code at the edge, and Bunny Database provides SQLite-compatible databases. SafeHop and Perma-Cache are named CDN features. Documentation is published for each product, and larger projects can contact sales directly.
