Companies Using Dreamweaver

I've spent most of my career on crawlers, and Dreamweaver is a detection that measures history more than software purchases. A domain counts here when its pages define one of the JavaScript functions Dreamweaver inserts (MM_preloadImages, MM_showHideLayers or MM_showMenu) or carry a generator tag naming Adobe Dreamweaver. As of our October 2026 crawl that's 76,872 domains, 55,150 of them matched to a company, 5th in Developer Tooling. It's a count of code that is still being served, not of people who still open the editor.

What the count measures

I loaded the top of our company list in a headless browser. On most pages the functions don't sit in the HTML at all. They live in a shared JavaScript file: a base script at The UPS Store and Hartford Hospital, a common script at ICBC, a Joomla template's utilities file at Jana Small Finance Bank. Some platforms ship them to every customer. Edlio school sites carry them in Edlio's common script pack, and Edlio runs on 2.48% of Dreamweaver domains. Blackbaud Luminate Online donation pages load them from a utils.js file, and Jenzabar student portals and Talentsoft careers sites from their own bundles. None of these is large. Edlio, the biggest platform, is 2.48%, and the biggest family of identical sites, an Italian travel-agent network called Evolution Travel, is 531 domains, about 0.7%.

Sales signal: on a small business's own domain, Dreamweaver code is a reliable flag for a site that hasn't been rebuilt in years. On a platform-hosted page, it tells you about the platform, not the customer.

Growth trajectory

The chart reads 64,014 in June 2026, then 74,285, 75,278, 76,742 and 76,872 in October. The June to July jump of 10,271 isn't a Dreamweaver revival. The set of domains we crawl turns over every month, with dead sites dropping out and new ones added, and our detection signals widen over time, so that step reflects changes on our side. The last month added 130. Since we began tracking it on 16 March 2026, 6,897 domains have dropped Dreamweaver code, and about 830 of those still carry it on another hostname.

"A rollover script written in Dreamweaver keeps running until someone rebuilds the site. On 76,872 domains, nobody has yet." - David Thomson, CTO at TechnologyChecker.io

Sales signal: this pool shrinks only when a site is rebuilt, which makes every domain on it a rebuild prospect rather than a software prospect. Agencies and website builders should read it as a list of overdue redesigns.

Who runs these sites

Very small, long-established businesses. 70.79% of matched companies have 1 to 10 employees and 88.55% have 50 or fewer. Age is where Dreamweaver stands apart: 50.69% were founded before 2000, against a median of 23.37% across the 554 technology profiles we publish, and only 2.17% in the 2020s. The 494 companies above 1,000 staff mostly carry the code on one corner of their estate. 32 of the 50 in our top list were detected on a subdomain: the University of Maryland's registrar, Arista's order portal, Wiley's Singapore customer site, Dassault Aviation's careers site. The UPS Store, ICBC, Pampered Chef and Sinar Mas carry it on their main sites.

Sales signal: at a large account, the owner of the Dreamweaver page is typically an application team (admissions, ordering, recruiting, fundraising), not the web team. Find the application first.

Germany, and a flat industry mix

The United States leads with 21,533 matched companies, but Germany is second with 5,430, ahead of the United Kingdom (3,362) and India (2,613). That's one German company for every 3.97 American ones; the median across the 520 profiles we publish with both countries is one for every 10.41. Industry is flat. Construction leads at 5.6%, then Retail (5.06%), Individual and Family Services (3.12%) and Real Estate (2.97%), and the ten charted industries add up to 29.75%.

Sales signal: for a rebuild offer, Germany is where this list runs densest compared with our other profiles, so budget for German-language outreach. Industry is a weak filter here; country and company age are stronger ones.

Where the sites go

One switching pair passed our tests. 52 domains dropped Dreamweaver code while running Squarespace, 34 of them in the last 90 days and 8 in the last 30, against 9 the other way. I loaded 10 of the 52: every one is a Squarespace site now, and the five I checked had no MM_ functions left. They're small businesses, among them a Highland games, an environmental consultancy, a law firm and an electrical contractor. WordPress is a different story. 6,170 domains have been seen with both, and 3,636 still run both, because old Dreamweaver pages tend to survive inside a WordPress site rather than being replaced by it. The Wix and GoDaddy Website Builder pairs didn't pass either; 807 of the 916 domains ever seen with Dreamweaver code and GoDaddy Website Builder still have both.

"When a Dreamweaver site moves, it moves to a hosted builder and the old code goes with it. When it moves to WordPress, the old pages often come along." - David Thomson, CTO at TechnologyChecker.io

Sales signal: for a builder, the 52 Squarespace rebuilds show the buyer: a small firm replacing a site it can no longer edit. For a WordPress agency, the 3,636 sites still mixing both are a clean-up job waiting to be quoted.

The stack around it

Percentages here are of the 76,853 live Dreamweaver domains left after we removed for-sale and gambling pages. jQuery runs on 52.15%, jQuery UI on 16.13% and jQuery Migrate on 11.34%. Apache serves about 42% of these domains, PHP about 20%, Microsoft ASP.NET about 10% and IIS about 8%. GoDaddy hosts 9.44% and the Plesk control panel runs on 5.18%, with IONOS (2.47%), OVHcloud (1.39%) and Aruba.it (1.38%) behind them. Bootstrap is on 15.26% and Tailwind CSS on only 1.86%.

Sales signal: shared hosting and a jQuery-era front end make these sites good targets for managed hosting, security and accessibility offers, all of which tend to start with "your site is out of date".

Key takeaways

1. 76,872 domains still serve Dreamweaver's code; that is a count of pages, not licences.

2. Old, small companies: 50.69% founded before 2000 and 70.79% with 1 to 10 staff.

3. Germany is unusually large, at one German company for every 3.97 American ones.

4. The one clean exit is a rebuild on Squarespace, 52 domains against 9.

5. Platforms such as Edlio still carry the code for their customers, so check before you assume.
