If you are looking for a CDN that will not cost you a fortune, then you should consider BunnyCDN. I have been using it for more than a year now. In this review, I will show you how it has helped me in making my site faster while saving a lot of bandwidth.

We will also discuss the important features and do some speed tests.

Initial Impressions

After starting this blog in 2019, I was looking for an affordable content delivery network. I had used Cloudflare in the past and had used Stackpath and KeyCDN, but BunnyCDN was a new name to me.

So, I was a bit skeptical at first. After looking at the figures on CDNPerf, I decided that it’s worth a try.

Features & Ease of Use

BunnyCDN offers all the important features you expect from a typical CDN.

  • 54 PoPs in 36 countries
  • Multiple Pull Zones within one account
  • Let’s Encrypt SSL with Custom CNAME subdomain
  • Edge Rules
  • Set bandwidth and request limits
  • Storage zones
  • API & FTP access for storage zones
  • Perma-cache & origin shielding
  • On-the-fly image optimization & WebP conversion (addon)

1. Edge Locations or PoPs

With 54 data centers spread across 36 countries, BunnyCDN has its presence on six continents. Here is a continent-wise breakdown of the number of data centers or edge locations:

  • North America – 13
  • South America – 2
  • Europe – 20
  • Africa – 2
  • Middle East – 1
  • Asia – 10
  • Oceania – 6

2. Pull Zones

A pull zone allows you to set the base URL from where the CDN should cache the files.

Configuring a pull zone involves two URLs:

  • Origin URL
  • Hostname or CDN URL

So, whenever a request hits a Hostname, the CDN checks if the file is available in the edge cache. If not, it pulls the file from your origin server and sends it to the user.

After that, it saves that file on the edge location’s cache for future request. Thus, the next visitor from that region gets served faster.

Creating a Pull Zone

Let’s see how you can create a pull-zone for your website. After signing up and logging in, head over to the Pull Zones page and click the Add Pull Zone button.

add pull zone

On the next page you have to set three things:

How to add pull zones in BunnyCDN
  1. URLs – Hostname & Origin – Give your site’s name as the hostname. For the Origin URL, enter your site’s domain. Alternately, if you want CDN on a specific folder only, add that to the domain name (eg., mysite.com/images).

    Note: You can have multiple pull zones for different directories of your site. For example, you can set one pull zone for mysite.com/images while another one for mysite.com/assets
  2. Standard or Volume Tier – Standard is the default choice. Keep it like that for most use cases.
  3. Prizing zones – Keep all the four zones checked if your visitors scatter all around the globe. Otherwise, you can uncheck any unnecessary zones.
    South Africa and South America zones are more expensive than the other two. So, disabling it can reduce your monthly bills slightly.

Standard & Volume Tiers

BunnyCDN standard & volume tiers

BunnyCDN offers two types of Pull zones – Standard and Volume. Standard will be the best option for most sites.

Volume tier is specially optimized for caching large files like videos. However, it is available on certain edge locations only (see the image above).

Finally, click the Add Pull Zone button to activate the newly added zone.

After that, you will see an instructions page describing the methods to integrate the Pull Zone with WordPress, Joomla, Drupal, or an HTML website.

How to add pull zones in BunnyCDN

Note down the URL of the newly created pull zone (looks like ****.b-cdn.net).

Then click on the Skip Instructions button to go access the Pull Zone’s Edit page.

3. Custom Domain with Let’s Encrypt SSL

Above, we have seen that the default URLs for your assets will be *.b-cdn.net. But with BunnyCDN’s Linked hostnames feature, you can connect your custom sub-domain to it and serve the cached assets from that subdomain. So your visitors won’t see BunnyCDN’s third-party URLs.

Custom sub domain with BunnyCDN

The default Hostname looks like:

yourpullzone.b-cdn.net

With CNAME sub-domain support, you can set something like:

cdn.yoursite.com

Adding the CNAME DNS Record

Before entering the sub-domain on BunnyCDN’s dashboard, you have to add the CNAME record from your domain’s DNS provider.

Open your domain’s DNS in a new tab. Then create a CNAME record and point it to the BunnyCDN URL you’ve got in the previous step (****.b-cdn.net). Enter an appropriate name for the host field (eg., cdn)

If you are confused about adding a CNAME, see this guide on GoDaddy. The process is similar for most providers.

Now, your sub-domain (cdn.yoursite.com) is pointing to ***.b-cdn.net.

Enter Subdomain as Hostname

Now, come back to your pull zone’s edit page on BunnyCDN. Under Add Custom Hostname, enter the new subdomain and click Add.

Adding custom hostname/sub-domain to CDN

Now, the sub-domain appears under Linked Hostnames.

Enabling SSL for the new Subdomain

BunnyCDN offers one-click Let’s Encrypt SSL certificates for sub-domains. If you wish, you can add a custom certificate from another authority also.

Other Settings for Pull Zones

There are also several other things you can configure for Pull Zones. We won’t be going into the details of each. The below screenshot will give you an idea:

4. Storage Zones

With the pull zones we discussed above, you don’t have full control over what files get cached and when. That means, pull zones retrieve data from your origin server when only when it receives a request.

Whereas with Storage Zones (a.k.a Edge Storage), you can permanently store data on BunnyCDN’s servers, just like you upload files to any web host. To upload files to the storage, you can use one of the following ways:

  1. Upload via the web interface
  2. FTP upload
  3. via BunnyCDN API
add new storage zone

For backups and archiving purposes that don’t need public access to the files, it is sufficient. You can consider it as a cheap alternative to S3 or Dropbox. The technology behind it is object storage rather than file-based storage. So there are no limits on the number of files you can store in a zone.

In addition, if you want to serve the files to your users from a public URL (like in a pull zone), you can do that too. Connect a pull zone (yes, pull zone), and set its origin URL to the Storage zone.

  • In short, a Storage zone connected to a pull zone works like Push CDN (similar to Amazon’s S3 storage connected to Cloudfront CDN).

The storage zones also supports geo-replication, which increases redundancy and reduces latency. Currently, replication is availabe in the following locations:

  • Los Angeles
  • New York
  • Falkenstein
  • Singapore
  • Sydney

  • The pricing is also quite cheap – $0.02 or $0.03 per GB per location per month depending on the replication zones you select. If you select all five locations, the total price becomes $0.11/GB/month.

5. Perma-Cache

With normal CDN caching, the assets in your pull zone’s edge locations expire after a set time. After that, the edge servers re-pull those assets from the origin server once again.

However, BunnyCDN has a new feature that allows storing the assets permanently on their servers – Perma-cache.

To enable it, you have to create a Storage Zone and connect it from your Pull Zone settings page. Once enabled, the connected storage zone stands in between the edge servers and your origin server. It caches every request and stores it permanently.

So, whenever a cached file expires on an edge server, it pulls from the storage zone instead of your origin server.

With replication, the edge servers pull from the nearest replication location. So, for expired cache files, the latency will be lower.

Overall, storage zones combined with perma-cache is a great way to reduce the load on your server while making the site load faster.

6. Origin Shield

Origin shield is another feature that is quite similar to Perma-cache. So, you need to activate only one of them.

With the origin shield, the request to your origin servers will only pass through the shielding server. However, unlike Perma-cache storage zones, the shield locations do not cache files permanently.

7. Video Streaming

Recently, Bunny has introduced a new feature for streaming videos. You can create Video Libraries as you do with Storage Zones. There are two pricing tiers, Standard and High Volume. Since it is for videos, selecting the High Volume Tier will be suitable, which costs $5/TB of bandwidth.

Not just hosting videos, Bunny also gives HTML5 player. So you can directly embed the videos to your web pages. Overall, it is a potential alternative to other video hosting services like Vimeo and Wistia.

8. Statistics & Monitoring

Ability to know the usage statistics is a must-have for CDNs. With Bunny, it’s easy.

At the top of your pull zone page, you can see the three important metrics – bandwidth, requests, and cache hit rate.

Statistics-bandwidth, requests, cache hit rate

Usually, your cache hit rate should around 70% or more. It may be lower during the initial days. But as more and more edge locations start caching your files, the rate should climb up.

In addition to this, the Statistics page show detailed information with line graphs and maps. You can filter metrics by date, location, and pull zone.

Apart from Statistics, the Logs section gives the details of each individual request. It includes HTTP status code, user’s IP, data center, and browser info. Looking at the logs can help to figure out problems easily.

Integrating with Your Website

In the above section, we have discussed how you can create a pull zone. Now let us see how you can integrate it with your website.

Replacing links on your site

For the CDN to start caching, you have to replace the origin URLs with the new pull zone URLs, which depends on what content management system or site builder you are using.

Integrating with WordPress

With BunnyCDN’s WordPress plugin, integrating and enabling CDN is quite easy.

The first step is installing it from the WP dashboard.

BunnyCDN WordPress Plugin

After installing it, go to the settings page of the plugin. If you hadn’t set a custom sub-domain, just enter your pull zone’s name and click Enable.

BunnyCDN WordPress Plugin Settings

Otherwise, if you had set a sub-domain as per the previous steps, click Switch to Advanced View.

BunnyCDN WordPress Plugin Settings

Enter the sub-domain and click Enable.

Now, all settings are complete. Open your site and inspect one of the assets to ensure that you are seeing the new CDN URL.

It is not a necessity to use the BunnyCDN WordPress plugin. If you are already using a caching plugin like W3 Total Cache or WP Super Cache, you can implement the link replacement from the respective cache plugins settings page. Check the W3 Total Cache settings tutorial to learn how.

Note: Be sure to purge any cache after enabling CDN. Otherwise, the old links can stay without changing.

Speed Tests – Before & After

A CDN is all about performance. So, what is the point of this review without some tests?

Test 1: Using sample HTML pages

For this test, I created two identical web pages.

On one, the assets (images, CSS, JS, and fonts) were loaded from the origin server (DigitalOcean). On the second, the assets were loaded from BunnyCDN.

Then I conducted multiple tests from multiple locations using GTMetrix to find the average page load times for each location as well as the worldwide average.

These were the results:

Performance Tests - BunnyCDN

As you can see, using BunnyCDN improved page speed by almost 37% (average). Somehow, South America (Sao Paulo) was slower with BunnyCDN.

Test 2: Using a WordPress site

Using demo sites for testing was enough to get an idea. However, since WordPress is so popular, that’s what most people want to know – how BunnyCDN speed up WordPress?

So I chose a WordPress site that was not well optimized. It also contained a few large images – perfect for testing a CDN.

These were the results:

  • Average load time without CDN – 2.9s
  • Average load time with BunnyCDN – 1.6s

With WordPress, BunnyCDN showed even better results with a 44% gain in speed. It confirmed the results from the previous test.

Also, according to the data from CDNPerf, it is faster that Stackpath and KeyCDN.

Pricing

Affordable pricing is the main attractiveness of BunnyCDN. They also give a 14-day trial. These are the per GB price for Pull Zones for different regions:

  • North America – $0.01
  • Asia & Oceania – $0.03
  • South America – $0.045
  • Middle East & Africa – $0.06

The payment is in the form of recharges, which means you have to charge your account a minimum of $10. Also, the minimum usage is $1/mo. Each year, you have to recharge with a minimum of $10 to prevent deactivation. Still, it is quite cheap in my opinion.

So, your credit card won’t be charged monthly. The minimum recharge amount is $10 though.

Currently, you can pay with your credit card, PayPal, or bitcoin.

Support Quality

Currently, support tickets are the only way to request help. The account says that more options and a Slack channel are coming soon. They often post on Twitter with the latest news and for feature suggestions.

Apart from that, their knowledge base articles cover almost all topics related to Account setup and CDN configuration.

During my time with Bunny, I had to contact the support a couple of times. And all the time, they were very knowleadgeable and clearly answered my questions.

In another ticket, I was asking about how I can use Bunny for backups. And the reply was clear and assuring.

  1. Hi! I am currently trying it out, but I guess I don’t get to configure everything fine, because I see no improvement at all on the load time. I think it broke other optimization features from other plugins, like Lazy loading or code reduction, and doesn’t work well.

  2. Thank you for your article.

    I’m finally moved from KeyCDN to BunnyCDN.
    It’s super simple and newbie friendly, only took 5 minutes to setup and all works flawlessly. And I got $5 free from promo code.

    I only use it to store images and zip files, and then pointed the pull to storage zone, setup redirect to subdomain, and that’s it.

    I can’t believe it spent a week to learn AWS S3, cloudfront, route53, cloudwatch, cloudtrail, it’s better to use BunnyCDN at the beginning.
    I’ll never ever touch AWS anymore. lol

  3. Thank you for this comprehensive review on Bunny CDN. I am already using it but there is something I wanted to know how to best I can use it. Luckily, I found the answer with this article. That’s why I could not leave without a vote of thanks. Well done
