Companies Using FastPixel

FastPixel is the smallest tool I looked at in our October 2026 Caching data, and small lists reward checking every row. A domain counts here when its pages load FastPixel's stats script from api.fastpixel.io, which the plugin adds to the optimised pages it serves. That gives 696 live domains, 465 matched to a company, 9th of 12 in Caching. FastPixel comes from the team behind ShortPixel, whose image service it uses, and its own site says it's made in Bucharest. It reached WordPress.org in May 2024.

Is the account still working?

The stats script can't answer that: it returns the same empty response for any URL I tried, customer or not. So I loaded every domain instead. 517 answered, and of those, 454 (87.8%) served pages FastPixel had optimised, with its script and images rewritten through its CDN. Another 33 (6.4%) sent FastPixel's cache header without an optimised page, which looks like an install that isn't processing pages, whether from a cache miss or an exhausted free allowance. 27 showed no FastPixel trace and 3 were dead or placeholder pages. Most of the 171 that didn't answer timed out on our side, so I can't score them.

Applied to the headline, that suggests about 600 working FastPixel sites. It's below 696, but well above anything that would change how this page reads.

Sales signal: for a list this size, check each domain before outreach. About one in eight that loaded wasn't serving an optimised page.

Growth, and a lot of churn

The chart reads 601 in June, 628 in July, 648 in August, 645 in September and 696 in October. Part of the movement is ours: the set of domains we crawl turns over every month, with dead sites dropping out and new ones added, and our detection widens over time. The churn is the striking part. 567 domains have dropped FastPixel from at least one hostname since 17 March 2026, and only 42 of those still run it on another hostname. For a base of 696, that's a lot of sites passing through.

"FastPixel is the rare small tool that takes sites from a much bigger one. In our data, 31 domains left WP Rocket for FastPixel and 5 went back." - Mehmet Suleyman, CEO & Co-founder at TechnologyChecker.io

Sales signal: FastPixel users try things. The 567 domains that dropped it are worth a look for any speed tool or host, because their owners already went shopping once.

A German-led customer base

Germany has 140 matched companies, more than the United States (123). The United Kingdom and France have 30 each and the Netherlands 23. Hosting is part of the reason. I resolved every domain, and 145 (20.83%) point at servers registered to Raidboxes, a managed WordPress host in Münster, most of them German .de sites. The ones I loaded each carry their own FastPixel cache header, so this isn't one account; it looks like agencies on Raidboxes recommending FastPixel to their clients.

Sales signal: German WordPress agencies look like FastPixel's main channel. If you sell to agencies in Germany, Austria or Switzerland, the FastPixel list tells you which ones already buy performance tooling for clients.

Small firms, built by agencies

67.45% of matched companies with a known size have 1 to 10 employees and 90.4% have 50 or fewer; only 2 have more than 1,000. Advertising Services leads the industries at 7.02%, LinkedIn's label for agencies, then Construction (6.02%) and Business Consulting and Services (5.26%). Among the 243 companies with a founding year, 23.05% were founded in the 2020s. The better-known names are Implico, the Hamburg maker of SAP software for downstream energy logistics, Five Rivers Cattle Feeding, Global Nature Fund and TalentLaunch.

Sales signal: the buyer is usually the agency, not the end client. Pitch the studio that maintains twenty small-business sites, not each business.

The WP Rocket corridor

This is the one finding I'd put in front of a FastPixel competitor. 31 domains dropped WP Rocket and now run FastPixel, 24 of them in the last 90 days, against 5 that went the other way. Of 46 domains ever seen with both, only 1 runs both today, so these are replacements, not stacked tools. Both products optimise the whole page, which makes it a like-for-like swap. FastPixel shares more sites with LiteSpeed Cache (43) and Varnish (25), but those caches usually come from the host.

"Thirty-one domains is small. But they all moved the same way, from a paid plugin that runs on your own server to a cloud service with a free tier." - Mehmet Suleyman, CEO & Co-founder at TechnologyChecker.io

Sales signal: for WP Rocket, FastPixel is a small leak that runs mostly one way, 31 out and 5 back. For FastPixel, WP Rocket's base of 718,843 domains in our caching table is the obvious prospect list.

The stack around it

Our WordPress rule fires on 77.26% of FastPixel domains; the rest are WordPress sites that hide the usual markers. Elementor runs on 33.97% and Divi on 18.8%, more than three times Divi's 5.64% on NitroPack's domains. Nginx answers for 38.78% and Cloudflare fronts 24.05%. Kinsta hosts 4.23%. None of this is a platform bundle; it's the toolkit of agencies that build on Divi and Elementor.

Sales signal: Divi and Elementor add-on sellers reach the same agencies FastPixel does.

What reviewers say

On WordPress.org, FastPixel has 50 ratings, 48 of them five-star, against 4,000+ active installations. That's a strong score on a small base. Pricing helps explain who signs up: a free plan for 1,000 pageviews a month on one site, then Plan A at $8.33 a month billed yearly for 300,000 pageviews on three sites (checked 16 October 2026). It's cheap enough for an agency to roll out across clients.

Sales signal: price isn't the lever against FastPixel. Speed results and agency tooling are.

Key takeaways

• 696 live domains, 0.02% of Caching, 9th of 12; about 87.8% of the pages that loaded were serving FastPixel-optimised pages.
• Germany (140) leads the United States (123), and 145 domains sit on Raidboxes.
• 31 domains moved from WP Rocket to FastPixel, against 5 the other way.
• 90.4% of matched companies have 50 or fewer staff, and agencies lead the industry list.
• 567 domains have dropped FastPixel since March 2026, so the base turns over fast.

Sales applications

Outreach: "Your site runs FastPixel, so speed matters to you. We help [agencies or site owners] with [your offer], and it works alongside FastPixel's cloud optimisation."

Targeting: on TechnologyChecker.io, filter FastPixel domains to Germany, Austria and Switzerland and to Advertising Services, then group by agency where the footer credits one.

Competitive angle: NitroPack and WP Rocket can pitch FastPixel's leavers; FastPixel can pitch WP Rocket's base with its own corridor as proof.
