How we choose
How we choose
Our full method is on how we score. We considered 11 CDNs that offer a WordPress plugin, a documented WordPress setup path, or a simple CNAME setup, and we kept 6 for this list. We reviewed vendor pricing pages, plan tables and setup guides between 28 Oct and 2 Nov 2026, and we checked every price again on 2 Nov 2026. We compared what a small site owner actually does in the first month: connect a domain, set cache rules for WordPress, purge the cache after a post, and read the first bill.
We scored each CDN on 5 criteria for a site with under 100,000 visits a month. Price at low traffic carried 30 points. WordPress setup and plugin support carried 25 points. Cache control and purge speed carried 20 points. Free plan or free tier value carried 15 points. Security features such as a firewall and DDoS protection carried 10 points. The weights add to 100. A CDN lost points when its pricing page hid the rate a small site would pay, or when WordPress login pages needed manual rules that a beginner could get wrong.
Cloudflare
Best for: Small WordPress sites that want a free start, DNS and protection in the same account as the CDN.
Cloudflare lists a Free plan at $0 per month and a Pro plan at $20 per month when billed annually or $25 per month when billed monthly Cloudflare pricing. Its plans page states that all plans include DNS, a global CDN and SSL, and that Pro adds image optimization and extra firewall features Cloudflare pricing. Prices checked 2 Nov 2026.
Pros:
- Free plan costs $0 and covers one small site well
- DNS, CDN, SSL and DDoS protection sit in one account
Cons:
- Plans are priced per domain, so a Pro fee repeats for each extra domain you upgrade
- The Business plan jumps to $200 per month when billed annually, a large step from Pro
- Free and Pro support is ticket based, with chat support listed for higher plans
Price: Cloudflare pricing lists Free at $0 per month and Pro at $20 per month when billed annually, checked 2 Nov 2026.
Skip it if: You run many small domains and want one flat fee for all of them. A per GB service such as Bunny.net can cost less across a group of low traffic sites.

Bunny.net
Best for: Low traffic WordPress sites that want the lowest clear per GB rate and a small starting bill.
Bunny.net lists Standard tier pricing at $0.01 per GB in Europe and North America, $0.03 per GB in Asia and Oceania, $0.045 per GB in South America and $0.06 per GB in the Middle East and Africa Bunny.net pricing. Its Volume tier starts at $0.005 per GB for the first 500 TB on a smaller network of 10 points of presence, against 119 on Standard Bunny.net pricing. Prices checked 2 Nov 2026.
Pros:
- Lowest per GB rate in this list for Europe and North America traffic
- Region prices are printed in a simple table with no quote step
- Standard and Volume tiers let a site change network as traffic grows
Cons:
- Traffic in the Middle East and Africa costs $0.06 per GB, six times the Europe and North America rate
- The cheaper Volume tier uses only 10 points of presence, against 119 on Standard
- There is no free plan, so you pay for usage from the start after any trial
Price: Bunny.net pricing lists Standard at $0.01 per GB in Europe and North America, checked 2 Nov 2026.
Skip it if: Most of your readers are in regions priced at $0.045 or $0.06 per GB. In that case a flat plan from Cloudflare or RocketCDN can cost less and is simpler to forecast.
[Bunny.net pricing](https://bunny.net/pricing/) lists Standard at $0.01 per GB in Europe and North America, checked 2 Nov 2026.
KeyCDN
Best for: Owners who want tiered pay as you go pricing with no plan choice to make.
KeyCDN lists pricing from $0.04 per GB for the first 10 TB in North America and Europe, with lower per GB rates as volume rises and higher rates in other regions KeyCDN pricing. Prices checked 2 Nov 2026. The appeal for a small WordPress site is the simple account model: you create a zone, point your asset URLs at it with a plugin, and pay for the data you serve. There is no plan ladder to climb and no per domain plan fee.
Pros:
- One clear starting rate of $0.04 per GB for the first 10 TB in North America and Europe
- Per GB rates fall as monthly volume grows, which rewards steady growth
Cons:
- No free plan is listed, unlike Cloudflare and the CloudFront free tier
- Regional rates are higher outside North America and Europe, so a global audience costs more
- At $0.04 per GB it costs four times the Bunny.net Standard rate for the same Europe and North America traffic
Price: KeyCDN pricing lists traffic from $0.04 per GB for the first 10 TB in North America and Europe, checked 2 Nov 2026.
Skip it if: Your site serves under 500 GB a month and price is your first concern. Bunny.net charges a quarter of the KeyCDN starting rate for that traffic in Europe and North America.
[KeyCDN pricing](https://www.keycdn.com/pricing) lists traffic from $0.04 per GB for the first 10 TB in North America and Europe, checked 2 Nov 2026.
Amazon CloudFront
Best for: WordPress sites already hosted on AWS, or owners who want a large free tier before they pay.
Amazon CloudFront pricing includes an always free tier of 1 TB of data transfer out and 10 million requests per month, then pay as you go transfer at $0.085 per GB for the next 9 TB in the United States, Canada and Europe rate group Amazon CloudFront pricing. AWS also lists flat rate plans from $15 per month for Pro on its pricing page Amazon CloudFront pricing. Prices checked 2 Nov 2026.
Pros:
- 1 TB free transfer each month covers many small WordPress sites in full
- Flat rate plans from $15 per month give a second billing choice on the same service
Cons:
- Pay as you go transfer at $0.085 per GB is the highest per GB rate in this list after the free tier
- Request charges apply on top of transfer charges, so the bill has more than one meter
- The AWS console and cache behavior settings are harder for a non technical owner than a WordPress first CDN panel
Price: Amazon CloudFront pricing lists $0.085 per GB for the next 9 TB after the free tier in the main rate group, checked 2 Nov 2026.
Skip it if: You want a CDN you can set up inside WordPress in ten minutes. CloudFront rewards AWS skills, and a beginner will finish faster with Cloudflare, Bunny.net or RocketCDN.

Fastly
Best for: Small sites with a technical owner who values instant purge and fine cache control over a low headline price.
Fastly lists usage pricing with bandwidth at $0.12 per GB for the first 10 TB in North America and Europe, and requests at $0.0075 per 10,000 HTTPS requests Fastly pricing. Prices checked 2 Nov 2026. Fastly is known for fast cache purge and detailed control over how content is cached and served, which helps a WordPress site that publishes often and cannot wait for old pages to expire.
Pros:
- Instant purge helps frequent publishers clear old pages fast
- Usage billing means a very small site pays a very small amount in a quiet month
Cons:
- Bandwidth at $0.12 per GB for the first 10 TB is twelve times the Bunny.net Standard rate
- Requests are billed apart from bandwidth, at $0.0075 per 10,000 HTTPS requests
- No flat small site plan is listed, so monthly cost is hard to state in advance
Price: Fastly pricing lists bandwidth at $0.12 per GB for the first 10 TB in North America and Europe, checked 2 Nov 2026.
Skip it if: Price per GB is your main test. Bunny.net and KeyCDN both serve WordPress assets for far less per GB, and Cloudflare Free costs $0 to start.

RocketCDN
Best for: WordPress owners who use WP Rocket and want one flat monthly fee with no usage maths.
RocketCDN lists a price of $8.99 per month for one domain with unlimited bandwidth, and an annual price of $89.99 RocketCDN pricing. Prices checked 2 Nov 2026. The service is built for WordPress and is sold by the WP Rocket team, so the setup path starts inside a tool many small site owners already know.
Pros:
- Flat $8.99 per month with unlimited bandwidth for one domain
- Built for WordPress, with a setup path that fits the WP Rocket workflow
Cons:
- One subscription covers one domain only, so each extra site needs its own plan
- No free plan is listed, so you pay from month one
- At very low traffic, $8.99 per month costs more than pay as you go rates at Bunny.net or KeyCDN
Price: RocketCDN pricing lists $8.99 per month for one domain, checked 2 Nov 2026.
Skip it if: You run three or more small sites. Three subscriptions cost $26.97 per month in total, while one Bunny.net account can serve all three on usage pricing.

Buyer questions
Which CDN is cheapest for a small WordPress site?
Cloudflare Free is cheapest at $0 per month Cloudflare pricing. Among paid options for low traffic, Bunny.net costs about $2 for 200 GB at $0.01 per GB in Europe and North America Bunny.net pricing. RocketCDN at $8.99 per month becomes cheaper than per GB billing once a site passes about 900 GB a month against the Bunny.net Standard rate, and sooner against KeyCDN or Fastly rates. Prices checked 2 Nov 2026.
How much traffic makes a flat plan worth it?
Divide the flat fee by the per GB rate. At $8.99 and $0.01 per GB, the break point is about 899 GB. At $8.99 and $0.04 per GB, it is about 225 GB. Most small WordPress sites sit below 500 GB a month unless they host large images or files, so usage pricing wins for most owners in year one.
Which CDN is best if you cannot change nameservers?
Bunny.net, KeyCDN and RocketCDN can serve WordPress assets without a full nameserver change, because they work through a pull zone, a CNAME record or a plugin setting. Cloudflare self serve plans work best when the domain uses Cloudflare DNS, which means a nameserver change at your registrar. If your registrar or host setup makes that change hard, start with a pull zone service and keep your current DNS where it is.
What should you check in the first month?
Check your cache hit ratio, your bill against your traffic, and whether logged in pages stay private. Also check image weight on your busiest pages, because one large photo gallery can use more bandwidth than a month of text pages. Note the pages that miss the cache most often, and look for a shared cause, such as a cookie set by a plugin, a query string used by a campaign link, or a page that your host marks as private. Fix one cause at a time, then check the ratio again after a week of normal traffic. Keep a short record of each change, with the date and the result, so you can undo a rule that breaks a form, a checkout step or a member page. That record also helps support staff if you raise a ticket later in the year.
