Companies Using Zammad

Most technologies on our Help Desk table are detected on a company's main website. Zammad is detected on the helpdesk itself. Our rule looks for the script behind Zammad's embeddable contact form, and every Zammad installation loads that script on its own pages. So the October 2026 count of 553 live domains, 406 matched to a company, 12th of 49 in Help Desk, is mostly a census of companies running their own Zammad. That makes it unusually clean.

What the count is made of

We fetched all 573 domains behind this page's charts. 528 answered. 368 were a Zammad helpdesk, 352 of them on a subdomain: support. on 150, helpdesk. on 70, ticket. on 30, help. on 25. Another 122 embedded the contact form on a website: 69 send tickets to their own Zammad server, 18 to a hosted zammad.com account and 35 to another domain's Zammad. The last 38 loaded but showed no form script in the page source, so it is either added after the page loads or has been taken out.

Sales signal: a Zammad row usually points at a support subdomain, not a marketing site. The person to reach is whoever runs that server: an IT lead or support manager.

Whose account is it?

For feedback widgets this question cut thousands of domains. Here it cuts none. Zammad has no shared vendor account: every form posts to a specific Zammad server, and the largest one serves only five domains, all of them one Swedish drinks company's own. Regler Connect's server takes the form for the Regler Systems sites; Perfood runs one hosted account for four of its health-app sites. The 35 forms that post to another domain are mostly sister companies or small IT providers serving one client. No hosting company or agency accounts for more than 1% of the count.

Sales signal: every row is a separate decision. There's no platform or reseller to approach for many sites at once.

Does it still work?

A Zammad form asks its server for a token before a visitor can send anything, and the server says whether the form is switched on. We made that request for all 122 embedded forms. 102 were enabled. Twelve servers didn't answer, four returned server errors, two returned not found and two had the form switched off: 20 forms that would fail if a visitor tried them, 3.49% of the 573 domains behind the charts. The 368 helpdesks answered our fetch, so they are running. Running isn't the same as patched. In September attackers used two Zammad flaws to break into DIVD, the Dutch vulnerability-disclosure nonprofit, and on 2 October CISA added both (CVE-2026-102489 and CVE-2026-102490) to its list of exploited vulnerabilities. Zammad says the first only affects version 6.5 and older, which no longer get regular updates, and it released 7.2.1, 7.2.2 and an emergency 6.5.5 between 6 and 15 October.

"Zammad is one of the few technologies where we see the product itself rather than a tag. When our crawler finds it, it has usually found a company's helpdesk, running on its own server." - Elif Arslan, CMO & Co-founder at TechnologyChecker.io

Sales signal: more than eight in ten embedded forms work. A dead form is a support gap worth pointing out to the site owner.

Growth, read carefully

The chart reads 217 domains in June 2026, 253 in July, 455 in August, 544 in September and 553 in October. The August step is ours: the set of domains we crawl turns over every month, dead sites out and new ones in, and our detection reached more helpdesk subdomains. Only 42 domains dropped Zammad since March 2026, and 9 of those still run it elsewhere.

Sales signal: low churn suits a self-hosted tool. Once a company has installed its helpdesk, it tends to stay.

Who the customers are

60% of matched companies have 1 to 10 employees and 29.87% have 11 to 50; only 2 of 385 have more than 1,000 staff. Four IT industries hold 62.07%. These are managed-service providers, software houses and telecoms that support their own customers: RA-MICRO, Faronics, Decalog, the TYPO3 Company. Universities are the other group, with the GIK Institute, Burman University and Hochschule Anhalt. The public sector shows up too: Notruf NÖ, Lower Austria's emergency call service, runs its support desk on Zammad.

Sales signal: sell to small technical teams that value control and data residency. A hosted pitch from a US vendor has to answer the self-hosting question first.

German-speaking at the core

Germany has 146 matched companies, more than three times the United States' 45. With Switzerland (18) and Austria (15), the German-speaking countries hold 55.25% of the country table. The stack fits: TYPO3 (4.01%), Contao (2.27%) and Borlabs Cookie (3.14%) are German favourites, and Matomo runs on 12.22% while Google Analytics reaches only 34.03%.

Sales signal: for privacy, hosting and support tooling, this is a European, self-hosting audience. Lead with data location and open standards.

Alternatives and overlap

osTicket is the like-for-like rival, with 1,337 domains, about 2.4 times Zammad's count. Both are free to run on your own servers. Hosted help desks barely overlap: 10 Zammad domains run Zendesk today, out of 15 ever seen with both, and no switching pair passes our tests.

Sales signal: Zammad users chose to run their own system. Migration offers aimed at them should start from self-hosting, not replace it.

What it costs

Self-hosted Zammad is free under the GPL v3 licence. Hosted plans on zammad.com (15 October 2026) cost €7, €16 or €25 per agent a month billed yearly, and self-hosters can buy support packages from €2,999 a year. Trials run 30 days. AI features are optional and billed at €0.03 per call.

Sales signal: the self-hosters pay nothing for the software, so the commercial opening is around it: support contracts, managed hosting, backups and integrations. The 18 sites posting to a zammad.com account are the ones already paying Zammad directly.

Key takeaways

1. 553 live domains, mostly Zammad helpdesks on support subdomains.

2. No platform or agency account; the largest shared server covers five domains.

3. All 368 helpdesks answered, and 102 of 122 embedded forms are switched on.

4. Small, IT-heavy and German-speaking: 60% have 1 to 10 staff, 55.25% of our country table is in DACH countries.
