Latest observation

For a small site where you want to test global performance for free, the best options are usually the ones with:

  • an easy setup
  • a free tier that includes CDN caching
  • a decent global edge network
  • simple analytics so you can compare regions

Best free CDN platforms to try

1. Cloudflare

Best overall free option

Why it’s good:

  • Very easy to set up
  • Strong global network
  • Free SSL, caching, basic WAF, DNS, and performance features
  • Good for testing latency and edge caching worldwide

Good for:

  • Small sites
  • Static sites
  • Basic dynamic sites
  • Comparing global load times quickly

Limitations:

  • Free plan has limited advanced controls
  • Some performance features are locked behind paid plans

2. Bunny.net

Best for simple, fast CDN testing

Why it’s good:

  • Very fast CDN
  • Clean dashboard
  • Easy pull-zone setup
  • Great value if you later upgrade

Free access:

  • Not a permanent free CDN in the same way as Cloudflare, but often offers trial credits or limited testing options depending on promotions

Good for:

  • Testing static assets globally
  • Measuring real-world CDN speed

Limitations:

  • Usually not fully free long-term
  • Some features require paid usage

3. GitHub Pages + Cloudflare

Best for static sites

Why it’s good:

  • GitHub Pages is free hosting
  • Cloudflare can sit in front of it for CDN acceleration and analytics
  • Great for personal sites, docs, portfolios, and landing pages

Good for:

  • Static HTML/CSS/JS sites
  • Global performance experiments

Limitations:

  • Static only
  • More manual setup if you want fine-tuned caching

4. Netlify

Good for static sites with global edge delivery

Why it’s good:

  • Free tier includes global CDN
  • Easy deploy from Git
  • Built-in performance-friendly static hosting

Good for:

  • Small static sites
  • Testing deployment speed and edge delivery

Limitations:

  • Best for static content
  • Free tier has usage limits

5. Vercel

Best for frontend apps and static sites

Why it’s good:

  • Very strong global edge delivery
  • Free tier is generous for small personal/testing use
  • Easy deployment for Next.js and static frontend projects

Good for:

  • Static sites
  • Jamstack apps
  • Frontend performance testing

Limitations:

  • Not ideal if you want to CDN-accelerate arbitrary external origins
  • Free tier limits apply

6. Fastly Free Trial

Good for enterprise-style testing

Why it’s good:

  • High-performance edge network
  • Great if you want to test serious CDN behavior

Limitations:

  • Not a permanent free plan
  • More complex than Cloudflare or Netlify

Best choices by use case

If you want the easiest free global test:

  • Cloudflare

If you have a static site:

  • Cloudflare + GitHub Pages
  • Netlify
  • Vercel

If you want to compare CDN providers:

  • Cloudflare
  • Netlify
  • Vercel
  • Bunny.net trial

What to measure when testing

To compare global performance, check:

  • TTFB (time to first byte)
  • LCP (largest contentful paint)
  • CDN cache hit ratio
  • Latency by region
  • Asset load time from different countries

Useful tools:

  • WebPageTest
  • PageSpeed Insights
  • GTmetrix
  • Pingdom
  • Chrome DevTools
  • Cloudflare analytics

Simple recommendation

If you just want the best free CDN platform for global testing, start with:

Cloudflare Free Plan

Then, if your site is static, compare it against:

  • Netlify
  • Vercel
  • GitHub Pages + Cloudflare

If you want, I can also give you a ranked shortlist by “easiest setup,” “best speed,” and “best for static sites.”
