Free and budget CDN for small sites: real prices 2026

Anyone managing four or five client websites faces the same question: should everything go behind a free CDN, or is it worth paying a few pounds per month to avoid surprises on traffic costs? We checked the official pricings from four providers on 16 October 2026. Two names that often appear in these comparisons – Fastly's entry-level offering and CDN panels from Italian providers like Register or Aruba – don't have a public per-GB consumption pricelist designed for a single small site: you either get a quote or face an undisclosed minimum spend, so we excluded them to avoid publishing numbers that don't exist anywhere official.

The table

Service	Free tier	Traffic price (beyond free)	PoPs	TLS certificates	Limits/notes
Cloudflare Free	Yes, $0/month	No published traffic limit	Global network, not quantified on public pricelist	Included (SSL Universal)	3 page rules, basic WAF
Cloudflare Pro	No (starts from Free)	$20/month with annual billing or $25/month monthly, per site	Same network as Free	Included	Image optimisation, wider WAF
Bunny CDN	No	$0.01/GB Europe and North America; $0.03/GB Asia and Oceania; $0.045/GB South America; $0.06/GB Middle East and Africa	119 PoPs (Standard network)	Not specified in pricelist consulted	Separate "Volume" network, 10 PoPs, from $0.005/GB for high volumes
KeyCDN	No	$0.04/GB North America/Europe on first 10 TB/month, drops to $0.01/GB over 100 TB; higher rates for Asia, Africa and Latam	Not listed on page	Included, no additional cost	$4/month minimum, first 3 zones free, $49 minimum payment
CDN77	No stable free tier	Entry threshold around $100/month ($0.02/GB), with first 50 GB traffic and first million requests included; Growth plan from $990/month up to 250 TB ($3.96/TB beyond threshold)	Network with 330 Tbps capacity, number of PoPs not stated	Not specified in pricelist consulted	Enterprise pricing on request

What actually differs between these figures

Cloudflare's free tier remains the most convenient starting point for a static site or blog: no published traffic limit and certificate included. The jump to Pro makes sense when you need image optimisation or a more comprehensive WAF, not for traffic itself, which remains unlimited on Free.

Bunny CDN and KeyCDN work on pure consumption, no free tier: the practical difference comes down to the pricing tier. Bunny holds a fixed price of $0.01/GB across Europe and North America regardless of volume, while KeyCDN drops progressively as traffic increases, but starts higher in the first bracket.

CDN77 is designed for medium to large volumes: the entry threshold around $100 per month and the Growth plan at $990 for 250 TB make it impractical for a single small site, better suited to those already managing multiple projects under one account.

Before you decide

Always check the pricelist on activation day: regional prices change often without general notice, only with silent page updates. Official links consulted: cloudflare.com/plans, bunny.net/pricing/cdn, keycdn.com/pricing, cdn77.com/pricing.
