Best CDN Providers for 2021

This Dallas-based company has become one of the most prominent CDN service providers since its founding in 2015. StackPath has already built a network of servers in 45 locations across Europe, Asia, Australia, and the Americas, establishing itself as a contender for the best CDN provider title.

CDN hosting at StackPath is reasonably priced and includes neat additions, the most important of which is Origin Shield. It serves as the initial caching point from which all edge locations pull data, sparing the bandwidth of your primary server. Purging the cache from the whole network takes literal milliseconds – visitors will never see a dated page. Even the basic plan comes with 1 TB of free traffic, with pricier plans offering more customization options.

If you’re looking for affordable CDN hosting, StackPath is an excellent choice. The starting price is just $10 a month for unlimited websites and requests, with 24/7 direct customer support and 1 TB of bandwidth. Additional traffic costs $0.04/GB up to 100 TB, and then it drops to $0.03/GB. For customers that need a more expansive plan, Edge Delivery plans add managed DNS, a firewall, and edge rules for $20+ a month. There are no hidden fees here: You’ll know exactly what you’re paying for.

Final Thoughts

StackPath simplifies the setup, management, and pricing of a CDN. And with its fantastic support team, it truly is one of the best, if not the best content delivery network provider on the market.

Cloudflare is a name people immediately associate with content delivery: It is by far the most renowned company in the business, with a massive CDN network and an unbeatable value proposition. After all, you can’t really go cheaper than completely free.

Cloudflare isn’t popular just because it’s the best free CDN out there, though. First of all, the company has incredible coverage, with servers in more than 100 countries across six continents. The only setup requirement is a DNS update, with no need to alter code. The biggest surprise is the fact that Cloudflare isn’t trying to coax its users into purchasing premium plans: Regardless of the plan they’re on, every user gets unlimited bandwidth, as well as threat blocking with DDoS and content spam protection.

You might be wondering why anyone would go premium, but Cloudflare’s paid plans have the best CDN for images. Upgrading to the Business or Enterprise plans gets you Cloudflare’s image-optimization software that reduces files in real time – a must-have tool for websites targeting smartphone audiences. On top of that, upgrading nets you priority in customer support queues and an improved firewall, making the switch from the free plan ever more worthwhile.

Final Thoughts

Cloudflare remains at the very top of the CDN world, even with ever-fiercer competition. Whether you want unlimited bandwidth for the unbeatable price of zero dollars or the premium image-optimization tools, it is hands-down the best freemium and the best image CDN.

What do Spotify and Reddit have in common, other than being the largest platforms in their niche? Just one thing – they both use Fastly. A CDN designed to provide lightning access to your content all around the world, it operates in dozens of countries. Each Fastly server is equipped with cutting-edge hardware to ensure near-instant connectivity. Many consider it the best CDN for video.

Fastly’s server achieves the fastest results in testing and purges its cache across all servers at an impressive pace, within 150 ms. It employs HTTP-based media streaming protocols optimized for audio and video delivery and maintains high-level security for each connection. Thanks to its event-based cache and so-called “surrogate keys,” you’ll also be able to clear specific cache content, like images, news posts, etc.

Fastly charges you as you go, meaning that your monthly costs will be directly affected by traffic. In other words, it’s not the ideal affordable CDN provider and has no pre-built plans. You can technically try it for free, but as soon as you reach $50 of traffic – roughly 400 GB – Fastly will start charging you according to your location. You’re expected to pay at least $50 a month, with the combined price starting at $0.12 per GB for the first 10 TB and $0.0075 per 10,000 requests.

Final Thoughts

Upgrading from Cloudflare to Fastly is a big step forward, but it doesn’t come cheap. As the name says, it may well be one of the best CDN providers in terms of speed and features, but you’ll need some deep pockets.

KeyCDN founders understand that not everyone is running the world’s largest content platform, and, sometimes, they might not want to overspend on a CDN. That understanding is just one of the things that helped KeyCDN grow into one of the top content delivery network providers.

Setting up your CDN is a breeze: Choose between origin pull or push, whether you want to copy the files from your website automatically, or you plan on uploading everything via FTP, and you’re practically set. KeyCDN doesn’t have too many servers, but they’re housed in crucial locations to cover most of the world. Security is top-notch, too. You’ll get an Origin Shield and a choice between a free TLS- or a custom certificate. If you host a lot of images, KeyCDN can process them all for the low price of $1 per 2,000 operations.

And that’s not the only affordable aspect. Like some other best content delivery networks, it charges based on your network’s traffic, starting with $0.04/GB for North America and Europe. The minimum monthly cost is just $4 – significantly cheaper than Fastly – but the minimum payment is $49, although you can spread these funds over the year. You can try our KeyCDN for free for 14 days.

Final Thoughts

KeyCDN is an ideal choice for the small online store-owners who are just starting to expand their business with content delivery networks. With a set of neat features for a more-than-affordable price, this is the best CDN, to begin with.

The name CDN77 probably won’t ring a bell to the average internet user. CDN77 serves companies like Scania, CentOS, and the European Space Agency with its large-file hosting and substantial compression capabilities. It certainly deserves a spot on our top CDN providers list. It is an ideal service for users that don’t need blazing speeds but do need quality storage.

Signing up with CDN77 gets you 50 GB of free storage. Along with that and servers in 44 worldwide locations, you’ll get integrated support for several popular CMS platforms and world-class compression tools. An SSL certificate is also included, with the option to upgrade to an A-graded certificate. Though it may not be the fastest in the business, feature-wise, CDN77 is still a top content delivery network.

Your monthly plan can start from $199 for 6 TB of bandwidth. After that, any overage will run you the industry average of $0.045/GB. If you buy a higher-tier plan, your overages get lower. You can upgrade your storage, too: for example, $20 a month will get you an extra 150 GB; you can also get more than that. However, the monthly plans are on the expensive side, even without additional storage options. As mentioned, the minimum monthly plan costs $199 for 6 TB of bandwidth, and the price more-or-less doubles for each of the four higher tiers.

Final Thoughts

Whether you’re looking for the best WordPress CDN or a network for hosting large files, CDN77 is a number one choice. It may not be the speediest option, but it offers more storage than the competition and many ways to protect your website against potential hacking. However, if fast connections are the lifeblood of your website, CDN77 is not the service for you.

Choosing a CDN for big projects can be a daunting task. Amazon’s CloudFront service offers excellent infrastructure features, solid protection options, and integration with Amazon Web Services. The speed performance is outstanding, and there are many options to tweak around.

Amazon is a name that carries weight, which is why it’s no surprise that CloudFront has as many as 13 regional edge caches and 215 edge locations worldwide. Suppose your site content cannot be cached from the nearby edge location. In that case, the service will pick it up from the closest regional cache. This allows site visitors to access the website pages more quickly, wherever they are, giving your sites better SEO rankings compared to using free CDN providers.

CloudFront also allows its users to optimize content delivery according to its demand. When the site visit is high, Amazon’s service will send more resources and power to follow up on the requests. After the site’s traffic demands decrease, the resources will be transferred to other sites.

One feature that offers excellent long-term benefits is the integration with AWS. Many of Amazon Web Service features that CloudFront users get access to have set the industry standards. The AWS Certificate Manager helps when handling a bunch of unique SSL certificates, where other CDN network providers might stumble around. On the other hand, the AWS Web Application Firewall secures site content from common cyberattacks. At the same time, the AWS Shield protects from DDoS attacks.

Users also have access to a vast number of options once they select the Create Selection button. Most of them are not needed for managing simpler content. However, advanced users will find many useful features to ease the burden on the server. We managed to get an average response time of around 30 ms with a bit of tweaking, which puts Amazon CloudFront at the forefront of top CDN hosting services.

The pricing is a double-edged sword here since you pay on-demand, but many services can add up the costs quickly. New users get 50 GB of data out monthly traffic for an entire year, along with two million HTTP/HTTPS requests and CloudFront Function Invocations per month completely free. In theory, the “pay for what you use” pricing should be a more economical solution. However, many minor aspects quickly add to the total cost, so it can get expensive quickly.

Costs like regional data transfers start from $0.085 for every used GB a month, depending on your content location. This pricing system can stack up unfavorably faster than with other CDN companies that have more uniform and straightforward costs. Data transfers to Origin cost more than $0.020 per GB. HTTP/HTTPS requests also rack up costs very quickly.

Final Thoughts

If you don’t mind the complex pricing scheme with rapidly increasing costs, Amazon CloudFront brings excellent infrastructure, security, and AWS features to the table. Couple that with top-tier speed performance and server load tweaking options, and you’ll get a fantastic CDN service.
