Fastly

Fastly is a content delivery network and edge cloud platform: it caches and serves websites from its edge locations and adds a web application firewall, bot protection and edge computing.

Fastly is chosen by engineering teams: it is configured through an API and a Varnish-based language. Direct customers are large publishers, media and streaming services, retailers and SaaS companies with a devops team and a hosting budget. A share of the 1,370,767 websites inherit Fastly from the platform they are built on, so the list mixes big self-managed properties with smaller vendor-hosted sites.

Buyers of this list sell infrastructure and security: observability and monitoring tools, DDoS and bot mitigation, cloud hosting, performance consulting, DNS and certificate services, and devops recruiting. A website that newly appears behind Fastly has just gone through an infrastructure change and is likely reviewing related vendors; one that dropped Fastly has moved its traffic to another provider, which is a signal for competing CDNs and for the tools that integrate with them.

Fastly serves 1,370,767 websites, which is 1.5% of all CDN detections we record. Websites on Fastly are most often served from United States (1,219,056), Germany (33,248) and Singapore (116), and .com, .io and .org are the most common domain endings.

Questions about Fastly websites

How many websites are hosted on Fastly?

As of November 2, 2026, 1,370,767 websites are served through Fastly, recognised from the response headers and the hostnames our crawler sees. The number is recalculated every night from our own crawl of the web.

Who buys lists of websites hosted on Fastly?

Competing hosting and infrastructure providers, monitoring, security and performance vendors, and agencies and developers who specialise in Fastly. A website on Fastly tells you how technical its team is and how much it spends on infrastructure; one that just moved there is mid-migration, one that left is choosing a new provider.

Where are Fastly websites hosted?

United States leads with 1,219,056 websites, followed by Germany (33,248) and Singapore (116). The country is where the website is served from; sites on a hosted platform show the platform's country.

How do I find websites that just moved to Fastly?

The New tab on this page lists websites where our crawler saw Fastly for the first time in the last days, newest first; the Dropped tab lists the ones that moved away. Both download with a subscription and refresh every morning.

How do I get a list of websites on Fastly?

A free BetaScan account downloads a {sample_rows}-row sample. A subscription from $69 a month gives the full list of 1,370,767 domains, or a dataset with emails, phones, country, hosting and ranks, filtered by country, TLD, rank and registration date. See pricing.

How does BetaScan detect Fastly?

Our crawler fetches the homepage of every domain we track and matches the page and its response headers against the signatures of 7,636 technologies. A website counts as using Fastly when its latest crawl shows the signature; when the signature disappears, the site moves to the dropped list.

How can you tell a website is served through Fastly?

Fastly leaves its marks in the HTTP response headers rather than in the page itself: a Via header mentioning Varnish, X-Served-By values naming cache nodes, X-Cache and X-Timer headers, and sometimes a Fastly-Restarts header. The HTML of the page is unchanged, so detection is based on the headers our crawler receives with the homepage.

Is Fastly used by large companies or small ones?

Mostly by larger ones when the company contracts Fastly directly: it is priced on traffic and configured by developers, which suits media, e-commerce and SaaS companies with engineering teams. Smaller sites appear in the list when their hosting or publishing platform uses Fastly for every customer. Filtering the list by rank separates the two groups well.

What does a new Fastly website mean for a seller?

A site that starts using Fastly has usually migrated hosting, launched a new platform or added a performance and security layer in front of an existing stack. That work is done by an engineering team that is actively comparing vendors, so the weeks after the switch are a good time to offer monitoring, security, logging or consulting services that fit a Fastly-based setup.
