About CDN and performance tools
A CDN caches your site on servers close to visitors and absorbs traffic spikes and attacks; performance services such as NitroPack also optimize pages to improve Core Web Vitals. Pricing follows 2 models. Usage-based CDNs bill per GB of bandwidth: BunnyCDN from $0.01/GB with a $1/mo minimum, and KeyCDN from $0.04/GB with a $49 minimum credit deposit. Flat plans start free: Cloudflare has a free tier with Pro from $20/mo on annual billing, and NitroPack has a free tier with paid plans from $7/mo. 5 of the 6 tools offer a trial.
What to compare before you choose
Per-GB billing or a flat plan
Usage pricing is cheapest for modest traffic, but the bill rises with bandwidth; flat plans are predictable. BunnyCDN is built for cost-conscious teams that want sub-cent per-GB rates, while Cloudflare's free and Pro plans are flat-priced. Estimate your monthly bandwidth before comparing.
Security included in the plan
Cloudflare's free tier includes DDoS protection, its main draw for startups. Our reviews flag BunnyCDN and KeyCDN for teams that need enterprise-grade WAF and bot protection built in. If security matters as much as speed, compare what each plan includes, not only the per-GB rate.
Setup effort and control
NitroPack is the easiest option here for WordPress and WooCommerce owners because it applies optimizations automatically, but it caps pageviews per plan and limits fine-grained control. BunnyCDN and KeyCDN need some configuration. Cloudflare sits in front of your host as a proxy and does not host the site.
