Short answer: at 2 TB a month, DigitalOcean Spaces has the lowest commercial bill in this table at $14.76, because its $5 plan includes 1 TiB of transfer. At 20 TB the order flips, and the flat Cloudflare Pro plan has the lowest bill in the table, provided its terms cover the traffic. Bunny CDN and KeyCDN suit teams that want per-gigabyte pricing they can estimate by region, while CDN77 and ImageKit are monthly plans.
Eight delivery services priced on the same two volumes, with each billing basis, minimum and plan allowance spelled out.
A CDN bill depends on how the vendor charges and how much you deliver. This page prices eight tools on the same two volumes, 2 TB and 20 TB a month, in US dollars. The buyer it has in mind runs a site or app that serves web pages to visitors in North America and Europe, billed monthly. Each row shows its billing basis beside the bill, so a flat plan and a per-gigabyte rate can be read at the same volume. Toolradar data: of the 34 CDN tools we track, the ones priced here split between flat monthly plans and per-gigabyte rates, so the lowest bill at a given volume depends on the billing model.
Methodology: this page compares eight tools. Prices are from the vendors' pricing pages as of October 25, 2026, linked in the footnote of the comparison table. Rows are ordered by the monthly bill at 2 TB, with ties broken by the bill at 20 TB, and jsDelivr is listed last with no commercial rate. Providers whose pages print no USD rate for both volumes are left out, except jsDelivr. Amazon CloudFront is not a Toolradar tool, so it appears only in the FAQ.
Two assumptions shape every row. First, 2 TB and 20 TB are treated as 2,000 GB and 20,000 GB, except DigitalOcean, which bills in GiB, so its row uses 2,000 GiB and 20,000 GiB. Second, the figures cover delivery only. Storage, request fees and add-ons are excluded unless a plan bundles them.

Other CDN tools worth considering

What a CDN bill is made of
A content delivery network keeps copies of your files on servers close to visitors, and vendors charge for the traffic those servers send. Two billing models dominate. Pay-as-you-go services, such as Bunny CDN, KeyCDN and Fastly, bill each gigabyte delivered, often with a price per region and a lower rate after each volume tier. Flat-plan services, such as Cloudflare and CDN77, bill a monthly fee for a plan, and that fee does not move with traffic inside the plan. Some vendors add storage or media features to the same bill, as ImageKit does with DAM storage. Those lines change the total without changing the delivery rate, so this page keeps the delivery charge and states its basis for every row. The CDN category covers the feature side of the same market, and this page covers only price.
Why the order changes with volume
A per-gigabyte bill grows with traffic, so the gap between a pay-as-you-go service and a flat plan widens as a site grows. A flat plan does not move until its included traffic or plan limit is reached. That is why the order in this table changes between the two volumes. At 2 TB, DigitalOcean Spaces has the lowest commercial bill, because its included transfer covers half the volume. At 20 TB, the flat Cloudflare plan keeps its monthly fee, while the per-gigabyte rows rise many times over. Anyone planning to grow should price both volumes and read the terms of any flat plan before signing up for it.
Key Features to Look For
Billing basis: per gigabyte, per region or a flat monthly fee, stated beside each bill.
Included transfer: a plan allowance sets the point where overage begins, such as the 1 TiB included with DigitalOcean Spaces or the 225 GB bandwidth on the ImageKit Pro plan.
Volume tiers: per-gigabyte rates fall after set thresholds, so a 20 TB bill is not simply ten times the 2 TB bill.
Regional rates: the same vendor can charge two or three times more in Asia and Oceania than in North America and Europe.
Scope: the figures cover delivery only, and storage, request fees and add-ons are excluded from every row.
What to check before you pay
-
Billing term: Cloudflare prices its Pro and Business plans differently when billed yearly and when billed monthly, so compare like with like.
-
Region: check where your visitors are before you take a North America and Europe rate, because per-gigabyte vendors in this table price regions differently.
-
Flat-plan terms: the Cloudflare plans page prints no bandwidth allowance for Pro or Business. Cloudflare's CDN terms for Free, Pro and Business let Cloudflare limit the CDN if it serves video or a disproportionate share of pictures, audio files or other large files without its paid services, so a site that serves mostly images or downloads may not qualify for the Pro fee at 20 TB.
-
Storage: DigitalOcean includes 250 GiB of storage in its plan, and storage above that costs $0.02 per GiB, which the table excludes.
-
Request fees: Fastly bills request fees on top of bandwidth, and those are not in the table.
-
Minimums: KeyCDN's minimum usage is $4 a month, and its page sets a separate minimum payment of $49.

Vendor prices in USD as of October 25, 2026, from these pages: Cloudflare plans, Bunny CDN pricing, DigitalOcean Spaces pricing, KeyCDN pricing, Fastly pricing, ImageKit plans, CDN77 pricing and jsDelivr. Delivery only. 2 TB is 2,000 GB, except DigitalOcean, which bills 2,000 GiB.
Mistakes to Avoid
- ×
Comparing one volume only. The order at 2 TB can reverse at 20 TB, as it does in this table.
- ×
Mixing units. DigitalOcean bills in GiB, while many per-gigabyte rates are quoted per GB, so the table keeps each basis in its own column.
- ×
Taking a monthly price without the billing term. Yearly billing lowers the monthly fee on Cloudflare's flat plans.
- ×
Assuming free means unlimited. jsDelivr's free service is for open-source projects, so a commercial site does not get that rate.
- ×
Ignoring regional pricing, which can change a North America estimate by a factor of two or three for visitors in other regions.
Expert Tips
- →
Estimate monthly delivery per region, then price each region separately on a per-gigabyte vendor.
- →
Price the bill at the volume you expect in twelve months, not only the volume you have today.
- →
Open the vendor's pricing page before you choose a plan, and check that the date on this table matches the page you are reading.
The Bottom Line
For 2 TB a month, DigitalOcean Spaces has the lowest commercial bill in this table for delivery, and storage above 250 GiB is billed on top. At 20 TB, the flat Cloudflare Pro plan has the lowest bill in the table, provided its terms cover the traffic, and the per-gigabyte rows cost many times more. Pick the flat plan only after its terms confirm that your traffic fits.
Frequently Asked Questions
How much does a CDN cost at 2 TB a month?
In this table the lowest commercial bill at 2 TB is DigitalOcean Spaces at $14.76, because its $5 plan includes 1 TiB of transfer. Bunny CDN and the Cloudflare Pro plan come next, tied at the same monthly bill. KeyCDN follows at $80 on North America and Europe rates, and the figures exclude storage and request fees.
Is there a free CDN?
jsDelivr describes itself as "A free CDN for open source projects", and its homepage prints no commercial price. Cloudflare lists a Free plan on its plans page, and its commercial flat plans are Pro and Business.
Which option costs the least at 20 TB a month?
Among the priced rows, the flat Cloudflare Pro plan keeps the same monthly fee at 20 TB, provided its terms cover that traffic: Cloudflare's CDN terms let it limit the CDN if a site serves video or a disproportionate share of large files without its paid services. The per-gigabyte rows rise with traffic, with DigitalOcean Spaces at $194.76 and Bunny CDN at $200 in this table.
Does Cloudflare charge for bandwidth?
The Pro and Business plans are priced per month, and no per-GB charge is attached to either plan in this table. Monthly billing costs more than yearly billing on both plans, so check the billing term before comparing.
How does Amazon CloudFront compare?
Amazon CloudFront is not a Toolradar tool, so it is not in the ranked rows. Its own pricing page lists a Pro flat-rate plan at $15 a month per distribution, with 50TB of data transfer and "No overage charges". That is below the Cloudflare Pro plan at both volumes, but the AWS plan terms still apply.
Do storage and requests change the bill?
Yes. The figures exclude storage, request fees and add-ons. Fastly bills request fees on top of bandwidth, and DigitalOcean charges $0.02 per GiB for storage above the 250 GiB in its plan.
