KeyCDN

What Is KeyCDN?

The CDN market has consolidated around two poles: free-tier behemoths like Cloudflare that bundle security, DNS, and compute alongside content delivery, and hyperscale cloud CDNs like AWS CloudFront that charge premium rates for the privilege of staying within one ecosystem. For teams that want neither the complexity of the former nor the cost of the latter, the middle ground has quietly thinned.

KeyCDN occupies that middle ground with intention. Founded in 2012 in Winterthur, Switzerland, KeyCDN is a focused content delivery network that does one thing well: deliver your content quickly, with transparent pricing and no feature bloat. There is no WAF, no DNS hosting, no serverless compute layer. There is a fast, reliable CDN with pay-per-use pricing, real-time analytics, and the quiet confidence of Swiss data privacy standards.

This restraint is KeyCDN's defining characteristic. In a market where CDN providers increasingly try to become full-stack infrastructure platforms, KeyCDN remains a CDN — and a good one. With approximately 40+ points of presence, HTTP/2 and HTTP/3 support, instant cache purging, and image processing capabilities, it provides the features most websites actually need without charging for the ones they do not. For small to mid-sized teams running WordPress sites, static assets, or media-heavy applications, KeyCDN's simplicity is its greatest strength.

Key Features

Pay-Per-Use Pricing

KeyCDN's pricing model is its most distinctive feature. Starting at $0.04/GB for Europe and North America, with volume discounts at higher tiers, the model is straightforward: you pay for the bandwidth you use, with a $4 minimum monthly charge. There are no complex tier structures, no feature gates, and no long-term contracts. This predictability is valuable for teams that need to budget accurately without worrying about surprise bills.

The $4 minimum is worth noting — it means KeyCDN is effectively a paid-only service with no free tier. For low-traffic sites, this minimum represents the floor. For sites delivering more than 100 GB/month, the per-GB rate becomes the relevant metric, and KeyCDN's pricing is competitive with most mid-tier CDN providers.

HTTP/2 and HTTP/3 Support

KeyCDN fully supports HTTP/2 with server push and multiplexing, as well as HTTP/3 (QUIC) for reduced connection establishment times. Automatic Brotli compression is enabled by default, delivering smaller payloads and faster page loads. These protocol-level optimisations deliver measurable performance improvements without requiring any application changes.

Image Processing

KeyCDN includes a built-in image processing pipeline that supports on-the-fly resizing, cropping, and automatic WebP conversion. Images are transformed at the edge and cached for subsequent requests. While more basic than dedicated image CDNs like Imgix or Cloudinary, the feature covers the most common image optimisation needs — responsive image generation, format conversion, and quality adjustment — without requiring an additional service.

Real-Time Analytics

The analytics dashboard provides real-time visibility into CDN traffic, including bandwidth usage, request counts, cache hit ratios, status codes, and geographic distribution. Raw logs can be forwarded to external logging services for deeper analysis. The dashboard is clean and functional, though it lacks the depth of enterprise analytics platforms.

Instant Cache Purge

KeyCDN supports instant global cache purging through both tag-based and URL-based invalidation. Purges propagate across all PoPs within seconds, which is essential for sites that update content frequently. The API supports programmatic purging, enabling integration with CI/CD pipelines and CMS publishing workflows.

Origin Shield

The Origin Shield feature adds an intermediate caching layer between the edge PoPs and your origin server. By consolidating cache misses through a single shield location, it dramatically reduces the load on your origin — particularly valuable for sites with traffic distributed across many geographic regions.

Security Features

KeyCDN provides token authentication for securing premium or restricted content, custom SSL certificates with free Let's Encrypt integration, and basic hotlink protection. However, it does not offer WAF, DDoS mitigation, or bot management. For teams that need these security features, KeyCDN will need to be paired with a separate security solution.

Pricing

KeyCDN's pricing model is refreshingly simple. You pay per GB of bandwidth delivered, starting at $0.04/GB for Europe and North America. Rates vary by region — Asia and South America are higher — and decrease with volume. A $4 minimum monthly charge applies, which is consumed by usage rather than being an additional fee.

There are no setup fees, no feature tiers, and no long-term contracts. All features (image processing, Origin Shield, real-time analytics) are included in the base per-GB rate. This unbundled approach means that the price you see is the price you pay.

For high-volume customers, KeyCDN offers custom pricing with dedicated support and tailored SLAs. The threshold for qualifying for custom pricing is not publicly documented, but teams delivering multiple terabytes per month should inquire.

Compared to competitors, KeyCDN sits in the middle of the market. It is more expensive per-GB than Bunny.net (which starts at $0.01/GB) but significantly cheaper than AWS CloudFront for most use cases. Its value proposition is the combination of competitive pricing with Swiss privacy jurisdiction — a meaningful differentiator for EU-focused organisations.

EU Compliance & Data Privacy

KeyCDN's Swiss headquarters provides a distinctive privacy advantage. Switzerland, while not an EU member state, has been recognised by the European Commission as providing an adequate level of data protection. The Swiss Federal Data Protection Act (FADP) is one of the most robust data protection frameworks in the world, and Swiss companies have a strong cultural tradition of privacy.

KeyCDN offers a Data Processing Agreement for customers who require formal GDPR compliance documentation. Data can be processed through European PoPs, and KeyCDN does not use customer traffic data for purposes beyond CDN service delivery and aggregate analytics.

For organisations that value privacy jurisdiction but do not necessarily require EU member state incorporation, KeyCDN's Swiss status provides a level of assurance that few CDN providers can match. Switzerland's political neutrality and strong rule of law add an additional layer of trust.

Who It's Best For

WordPress site owners and agencies who need a reliable, affordable CDN with easy integration. KeyCDN's WordPress plugin and straightforward configuration make it a natural fit for the WordPress ecosystem.

Small to mid-sized development teams that need a CDN without the complexity of Cloudflare's full platform or the cost of AWS CloudFront. KeyCDN does content delivery well, and that is all it tries to do.

Privacy-conscious European organisations that value Swiss data protection jurisdiction. For teams where the CDN provider's legal jurisdiction matters, KeyCDN's Swiss incorporation is a genuine advantage.

Teams with predictable, moderate bandwidth needs — typically 100 GB to 10 TB per month — where KeyCDN's per-GB pricing is most competitive.

The Verdict

KeyCDN is not trying to be everything to everyone. It is a focused, well-executed CDN with Swiss privacy standards, transparent pricing, and the features that most websites actually need. The trade-off is clear: you get simplicity and privacy at the expense of advanced security features and a smaller PoP network. For teams that need WAF, DDoS protection, or a global network of 200+ PoPs, KeyCDN is not the right choice. But for teams that value straightforward content delivery with genuine European privacy credentials, KeyCDN delivers exactly what it promises — no more, no less.
