10 Best Free CDN Services of 2026

1. 1

   Cloudflare

   A reverse proxy CDN whose Free plan caches and protects any website you point at it.

   9.7overall

   A reverse proxy CDN whose Free plan caches and protects any website you point at it.

   Best forSite owners who want edge caching, SSL and DDoS protection on a custom domain for $0.

   Adoption data

   28.8%W3Techs detected Cloudflare on 28.8% of all websites in its November 2026 survey, which is 86.3% of the sites that use any reverse proxy service it tracks.

   W3Techs (Q-Success), Usage Statistics and Market Share of Reverse Proxy Services for Websites, November 2026 (2026): “Cloudflare is used by 28.8% of all the websites, that is a reverse proxy service market share of 86.3%.”

   Cloudflare is the default answer for a free CDN because its Free plan is a full reverse proxy, not a trial or a library host. Once your domain's nameservers point to Cloudflare, it caches static files at the edge, issues a Universal SSL certificate, hosts DNS and applies unmetered DDoS protection plus a free managed WAF ruleset. Its plans page lists that tier at $0 per month for personal or hobby projects that are not business-critical, and the Pro plan at $20 per month billed annually adds lossless image optimization and more WAF rules. Scale is the other reason to pick it: W3Techs finds Cloudflare on 28.8% of all websites, far ahead of any rival, so setup guides for WordPress, static site generators and frameworks are easy to find. The trade-offs are control and guarantees. You hand over DNS, the 100% uptime SLA starts at Business, and caching rules on the Free plan are more limited than on paid tiers.

   Strengths

   • +The $0 plan works for any site on your own domain, not only static files
   • +In front of 28.8% of all websites, per W3Techs
   • +Clear upgrade path to Pro and Business plans

   Limitations

   • −You must move your DNS to Cloudflare to use the Free plan proxy
   • −Cloudflare describes the Free plan as for projects that are not business-critical
   • −No uptime SLA on Free or Pro

   SummaryCloudflare is the best free CDN for most websites because the $0 plan caches any site on your own domain and adds SSL and DDoS protection. Upgrade to Pro only when you need image optimization or more WAF control.

2. 2

   Amazon CloudFront

   AWS's global CDN, now sold as flat-rate plans that start with a $0 Free plan per distribution.

   9.1overall

   AWS's global CDN, now sold as flat-rate plans that start with a $0 Free plan per distribution.

   Best forTeams already on AWS who want a free CDN in front of S3 or other AWS origins.

   Adoption data

   5.2%W3Techs found Amazon CloudFront on 5.2% of the websites whose reverse proxy service it can identify in November 2026, which is 1.7% of all websites.

   W3Techs (Q-Success), Usage statistics and market share of Amazon CloudFront, November 2026 (2026): “Amazon CloudFront is used by 5.2% of all the websites whose reverse proxy service we know.”

   Amazon CloudFront used to be a pay-per-GB service, but its pricing page now leads with flat-rate plans, and the first one costs $0 per month per distribution. The Free plan includes 1 million requests and 100 GB of data transfer a month with no overage charges, plus always-on DDoS protection, custom DNS, a TLS certificate and bundled extras such as Route 53 DNS and S3 storage credits. If your files already sit in S3 or another AWS origin, AWS waives the origin data transfer to CloudFront, which removes a common hidden cost. The Pro plan at $15 per month raises the allowance to 10 million requests and 50 TB, which is a large jump for the money. W3Techs puts CloudFront on 5.2% of sites whose reverse proxy it can identify, second only to Cloudflare. The catch is the 100 GB ceiling on the Free plan and the AWS console, which takes longer to learn than a simple nameserver change.

   Strengths

   • +Free plan with a predictable $0 bill and no overages
   • +Second largest reverse proxy share after Cloudflare, per W3Techs
   • +Pro plan at $15 per month jumps to 10M requests and 50 TB

   Limitations

   • −The Free plan caps usage at 1M requests and 100 GB a month
   • −Best value assumes your origin already lives on AWS
   • −Plan setup sits inside the AWS console, which is busy for beginners

   SummaryCloudFront is the best free CDN for teams on AWS, with a $0 flat-rate plan and no overage charges. Sites that need more than 100 GB a month should compare Pro at $15 with Cloudflare Free.

3. 3

   jsDelivr

   A free public CDN that serves any file published to npm or GitHub.

   8.8overall

   A free public CDN that serves any file published to npm or GitHub.

   Best forDevelopers who want to load open source JavaScript, CSS or fonts from a fast public CDN.

   Adoption data

   150 billionjsDelivr's homepage reported 150 billion requests served in the past month when we checked in November 2026.

   jsDelivr, jsDelivr: A free, fast, and reliable CDN for JS and open source (2026): “150 billion requests past month”

   jsDelivr is free in the plainest sense: its About page says there are no bandwidth limits or premium features and that anyone can use it. It is a public CDN for open source files, so any package published to npm or any GitHub repo can be loaded through a jsDelivr URL with a version number, and it can minify or combine files on demand. Instead of running one network, jsDelivr balances traffic across CDNs provided by Cloudflare, Fastly, Bunny and Gcore, plus its own servers, and drops a provider in a region when its response times slip. That design is why its homepage reports 150 billion requests in the past month. The limit is scope. jsDelivr cannot cache your HTML, images on your own domain or a WordPress site, so it complements a site CDN rather than replacing one. It also depends on sponsors donating the traffic it serves, which is worth knowing if you plan to rely on it long term.

   Strengths

   • +Completely free with no bandwidth limits or premium tier
   • +Multi-CDN design fails over between providers
   • +Locations near Chinese urban centers for lower latency there

   Limitations

   • −Only serves open source files from npm and GitHub, not your own site
   • −No custom domain, so it cannot cache your HTML pages
   • −Depends on sponsors for the traffic it serves

   SummaryjsDelivr is the best free CDN for open source libraries, with no limits and a multi-CDN failover design. Pair it with Cloudflare or a host CDN for the rest of your site.

4. 4

   cdnjs

   A free, community-run CDN for popular JavaScript, CSS and font libraries, hosted by Cloudflare.

   8.5overall

   A free, community-run CDN for popular JavaScript, CSS and font libraries, hosted by Cloudflare.

   Best forSite owners who want to load a common library such as jQuery or Bootstrap from a stable public URL.

   Adoption data

   12.5%cdnjs says on its About page that it is used by 12.5% of all websites and serves more than 250 billion requests per month.

   cdnjs, About cdnjs (2026): “12.5% of all websites 250B+ Requests per month”

   cdnjs is a free, open source and community-driven CDN for the most popular JavaScript, CSS and font libraries, and Cloudflare sponsors and hosts it. You pick a library from its catalog, copy a URL and drop it into a page, with no build step or npm install. Its About page reports that it serves 12.5% of all websites and more than 250 billion requests a month from over 330 edge locations, which shows how many sites still load jQuery, Bootstrap or Font Awesome this way. That reach and Cloudflare backing make it a dependable default for common libraries. It does far less than a site CDN, though. cdnjs only hosts libraries accepted into its catalog, so it cannot cache your own images, pages or uploads, and it has fewer packages than jsDelivr, which mirrors npm automatically. Treat it as a free helper for third-party code, alongside a CDN that caches the site itself.

   Strengths

   • +Free with no account or sign-up
   • +Backed by Cloudflare infrastructure
   • +Self-reported use on 12.5% of websites

   Limitations

   • −Hosts only libraries in its catalog, not your own files
   • −No custom domain or page caching
   • −Fewer packages than jsDelivr, which mirrors all of npm

   Summarycdnjs is a dependable free CDN for well-known libraries, backed by Cloudflare. It cannot cache your own content, so use it next to a site CDN.

5. 5

   Fastly

   A programmable edge cloud with a free usage tier for CDN delivery.

   8.5overall

   A programmable edge cloud with a free usage tier for CDN delivery.

   Best forDevelopers who want fine control over caching and edge logic and a free monthly allowance.

   Adoption data

   2.8%W3Techs found Fastly on 2.8% of the websites whose reverse proxy service it can identify in November 2026, which is 0.9% of all websites.

   W3Techs (Q-Success), Usage statistics and market share of Fastly, November 2026 (2026): “Fastly is used by 2.8% of all the websites whose reverse proxy service we know.”

   Fastly runs one of the large commercial CDNs, and its pricing page gives every account a free allowance: the first 100 GB of bandwidth and 1 million requests each month cost nothing. After that, bandwidth is billed per GB by region, starting at $0.12 in North America and Europe for the next 10 TB. That makes Fastly a good free option for low-traffic sites and prototypes, with the same edge platform that larger customers use. Its strength is control. Fastly is built as a programmable edge, so developers can write custom caching and routing logic instead of relying on presets, and it sells bot and content protection on the same network. W3Techs places it third among reverse proxy services at 2.8% of identified sites. The downsides for a budget-minded site owner are an uncapped bill once traffic passes 100 GB, per GB rates above budget providers such as Bunny.net, and a setup that assumes some technical comfort.

   Strengths

   • +Free tier is a real allowance on the production network
   • +Fine-grained cache control suits complex sites
   • +Third largest reverse proxy share in W3Techs data

   Limitations

   • −Traffic beyond 100 GB is billed per GB, so the bill is not capped
   • −Steeper learning curve than a one-click proxy
   • −Per GB rates are higher than budget CDNs such as Bunny.net

   SummaryFastly is a strong free CDN for developers who want a programmable edge and a 100 GB monthly allowance. Watch traffic closely, since usage past the free tier is billed per GB.

6. 6

   Netlify

   A web platform whose free plan deploys sites and apps to a global CDN.

   8.3overall

   A web platform whose free plan deploys sites and apps to a global CDN.

   Best forDevelopers and small teams who deploy static sites and Jamstack apps from Git.

   Adoption data

   10 millionNetlify's homepage says more than 10 million developers use the platform and more than 60 million apps have been deployed on it.

   Netlify, Push your ideas to the web (2026): “10M+ developers 60M+ apps deployed”

   Netlify's Free plan is listed at $0 forever and deploys sites from Git, the API or AI tools to its global CDN, with unlimited deploy previews, firewall traffic rules and basic rate limiting. The plan now runs on credits: Free accounts get a 300 credit limit each month, and bandwidth is metered at 20 credits per GB, so pure static traffic tops out at roughly 15 GB before other usage. That suits portfolios, docs sites and small marketing pages better than busy blogs. Netlify says more than 10 million developers use the platform and over 60 million apps have been deployed, so templates and framework guides are plentiful. If you need more, the Personal plan costs $9 per month for 1,000 credits, a lower first step than most rivals. The trade-offs are that credits make free capacity harder to predict than a plain GB allowance, and like Vercel it only caches sites you host on Netlify.

   Strengths

   • +Free plan listed at $0 forever
   • +Over 10 million developers, per Netlify
   • +Personal plan at $9 per month is a low first step up

   Limitations

   • −Credit-based metering makes free bandwidth harder to estimate
   • −300 credits a month covers modest traffic only
   • −Sites must be deployed to Netlify rather than proxied

   SummaryNetlify is a solid free host and CDN for small static sites, with a cheap $9 Personal plan when you outgrow it. Estimate your bandwidth first, since 300 credits go quickly.

7. 7

   Vercel

   A frontend cloud whose free Hobby plan deploys sites to a global CDN from Git.

   8.3overall

   A frontend cloud whose free Hobby plan deploys sites to a global CDN from Git.

   Best forDevelopers deploying personal Next.js, React or static projects who want CDN delivery included.

   Vercel is a hosting platform rather than a standalone CDN, but its free Hobby plan puts every deployment on a global, automated CDN, which is why it belongs on a list of free options. Vercel's docs say Hobby is free and aimed at personal projects and small-scale applications, and it includes the first 100 GB of Fast Data Transfer, 1 million CDN requests and 10 GB of origin transfer each month. Pushing to Git triggers automatic builds and preview deployments, and a web application firewall and DDoS mitigation come with the plan. For Next.js sites in particular it is the shortest path from repo to cached pages at the edge. The limits are the point to check. Hobby has no billing cycle, so if you exceed usage you usually wait until 30 days have passed or move to Pro at $20 per month. It also requires hosting the site on Vercel, so it is not a fix for an existing server.

   Strengths

   • +Free Hobby plan bundles hosting, builds and CDN
   • +Strong fit for Next.js and other frameworks
   • +Hobby has no billing cycle, so there is no surprise bill

   Limitations

   • −Hobby is aimed at personal and small-scale projects
   • −Exceeding Hobby limits means waiting up to 30 days or upgrading
   • −You host the site on Vercel; it is not a proxy for an existing server

   SummaryVercel Hobby is the best free choice for personal framework projects that want hosting and CDN in one deploy. Commercial or growing sites will need Pro at $20 per month.

8. 8

   Bunny.net

   A pay-as-you-go CDN with very low per GB prices and a $1 monthly minimum.

   7.8overall

   A pay-as-you-go CDN with very low per GB prices and a $1 monthly minimum.

   Best forSite owners who outgrow free tiers and want the smallest possible CDN bill.

   Adoption data

   1,500,000Bunny.net's homepage says more than 1.5 million websites are powered by its network.

   Bunny.net, bunny.net: The Global Edge Platform that truly Hops (2026): “Join 1,500,000+ websites already powered by bunny.net”

   Bunny.net does not have a permanent free plan, but it earns a place here as the cheapest step up when free tiers run out. Its pricing page lists pay-as-you-go rates from $0.01 per GB in Europe and North America on the Standard network of 119 PoPs, with a $1 monthly minimum and every feature included. Bunny.net's own comparison on that page prices 5 TB of traffic in those regions at $50. A 14-day free trial needs no credit card, and Bunny.net charges no request fees, only bandwidth. The company says more than 1.5 million websites use its network, and W3Techs measures Bunny CDN on 0.3% of sites whose reverse proxy it can identify. For a site owner who wants edge caching without a monthly bill, the honest framing is that Bunny.net costs a little, not nothing. It fits sites whose traffic exceeds the CloudFront or Fastly allowances.

   Strengths

   • +Lowest per GB price among the paid options here
   • +Predictable billing for small sites
   • +Over 1.5 million websites, per Bunny.net

   Limitations

   • −No permanent free plan, only a 14-day trial
   • −$1 monthly minimum applies even with little traffic
   • −Smaller reverse proxy share than the big three in W3Techs data

   SummaryBunny.net is the lowest-cost fallback once free tiers are not enough, at $0.01 per GB with a $1 minimum. Choose it for predictable, near-zero bills rather than a true free plan.

9. 9

   Gcore

   A global edge network whose CDN includes 1 TB of free traffic every month.

   7.7overall

   A global edge network whose CDN includes 1 TB of free traffic every month.

   Best forSites with steady traffic above typical free tiers that still want most usage at no cost.

   Gcore stands out for the size of its free allowance. Its CDN pricing page includes 1 TB of CDN traffic, 1 billion requests and 10,000 image optimizations free every month on the pay-as-you-go network, and the CDN product page invites sign-up with no credit card needed. That is ten times the free traffic of CloudFront's Free plan or Fastly's tier. The network spans more than 210 edge PoPs with 200 Tbps of DDoS filtering capacity, and jsDelivr uses Gcore as one of its CDN providers. Above 1 TB, traffic is billed per GB, but from our location the pricing page shows rates in euros, so we have marked USD pricing as pending. The other gap is adoption: we could not find a citable independent share figure for Gcore, so we scored that factor conservatively. Options such as dedicated IPs and direct origin connections are routed to a CDN expert rather than sold self-serve.

   Strengths

   • +Largest free traffic allowance on this list
   • +No credit card needed to start
   • +Pay-as-you-go above the free allowance

   Limitations

   • −Pricing page shows EUR from our location, so USD rates are pending
   • −Far smaller user base than Cloudflare or CloudFront
   • −Advanced options such as dedicated IPs go through sales

   SummaryGcore offers the largest free traffic allowance here at 1 TB a month. It suits sites that outgrow 100 GB tiers but do not want to move DNS to Cloudflare.

10. 10

    Firebase Hosting

    Google's static and single-page app hosting, served from a global CDN.

    7.4overall

    Google's static and single-page app hosting, served from a global CDN.

    Best forApp developers already using Firebase who need to host a small web front end.

    Firebase Hosting is Google's hosting for static and single-page web apps, and its docs say each deploy goes to a global CDN with a single command and zero-configuration SSL. The free Spark plan includes 10 GB of storage and 360 MB of data transfer a day, along with custom domains, SSL and multiple sites per project. On the pay-as-you-go Blaze plan, transfer beyond the free allowance costs $0.15 per GB and storage $0.026 per GB. For app developers already using Firebase Authentication or Firestore, it is the easiest way to put a web front end behind a CDN without another vendor, and Cloud Functions or Cloud Run can add dynamic routes. As a general free CDN it is limited. The 360 MB daily cap works out to about 10 GB a month, the smallest allowance among the hosting options here, and it only caches content you deploy to Firebase. We found no citable usage figure specific to Hosting, so adoption is scored conservatively.

    Strengths

    • +Free Spark plan with custom domain and SSL
    • +Simple CLI deploys
    • +Fits teams already using other Firebase services

    Limitations

    • −Free transfer is only 360 MB a day, about 10 GB a month
    • −Optimized for static and single-page apps
    • −Overage needs the pay-as-you-go Blaze plan

    SummaryFirebase Hosting is a convenient free CDN for Firebase app front ends, with SSL and custom domains on Spark. Its small daily transfer cap rules it out for busy sites.
