Companies Using osTicket

I expected osTicket to be a list of abandoned installs, because a self-hosted help desk that nobody patches tends to stop answering. So before writing anything I fetched every domain in our October 2026 crawl. A domain counts here when a hostname on it sets osTicket's session cookie, OSTSESSID, which only osTicket writes. Of the 1,382 live domains behind this page, 1,331 (96.31%) still served an osTicket page or that cookie on 15 October; 55 of them only answered a request from a US address. Our headline is 1,337 domains, 1,012 of them matched to a company, 9th of 49 in Help Desk.

One install, one subdomain

osTicket has no shared account, no agency key and no hosted network in this count, so the usual question on these pages, whose account is it, has a simple answer. On 1,310 of the 1,382 domains (94.79%) it runs on a subdomain of its own: support. on 563 domains, helpdesk. on 142, soporte. on 104 and ticket. on 88. The other 72 run it on the root or www. Page titles are almost all different, from "ICT Support Team" at the University of the Philippines to "Paid Support Helpdesk" at a file-format software maker; apart from blank ones, the most repeated is osTicket's own default, on 7 domains. Enhancesoft sells a hosted version, SupportSystem, but none of the hostnames we resolved points at it, so this is a list of self-hosted installs.

Sales signal: each row is one organisation's own server. The person who looks after it is most likely in IT rather than customer service, and that's who to reach.

Flat since September

The chart reads 271 domains in June, 359 in July, 1,065 in August, 1,334 in September and 1,337 in October. I wouldn't read the August step as adoption. It reflects changes on our side: the set of domains we crawl turns over every month, with dead sites dropping out and new ones added, and our detection widened over the summer. What the data does show is low churn. Since we began tracking osTicket in March 2026, 29 domains have dropped it, and 2 of those still run it on another hostname.

"I went looking for abandoned servers and found working help desks. Twenty-nine drops in seven months, on a base of 1,382, is a product people keep." - Sophie Clarke, Product Marketing Manager at TechnologyChecker.io

Sales signal: don't pitch a replacement on the assumption these desks are dying. The better opening is what a self-hosted install lacks, such as chat, managed upgrades or reporting.

Small IT firms, with universities on top

51.03% of matched companies with a known size have 1 to 10 employees and 31.83% have 11 to 50. By industry, IT Services and IT Consulting alone is 27.52%, and the four technology industries together are 50.28%. Our company list looks different because it is sorted by LinkedIn audience, which pushes universities to the top: the University of the Philippines, Çukurova University, Dow University of Health Sciences. 21 matched organisations have more than 1,000 staff, most of them universities. The founding years lean older, with 37.7% from the 2010s, 30.13% from the 2000s and only 6.99% from the 2020s. osTicket publishes no customer list to check these against. Its FAQ says it has no relationship with the organisations using the software, which fits a free download.

Sales signal: two buyer types sit on this list. Small IT and hosting firms most likely point their own clients at it; universities and school districts use it for staff and student IT support. Write to them separately.

Spanish, Portuguese and German

Only about 15% of the 1,012 matched companies are in the United States (152). Germany has 80, Italy 68, the United Kingdom 58 and India 55. The bigger group is Spanish- and Portuguese-speaking: Brazil (45), Spain (45), Colombia (30), Mexico (27) and Portugal (19) add up to 166, more than the US. The hostnames say the same, with soporte. and suporte. among the most common labels. A smaller pattern stands out too: at least 17 domains run osTicket as a complaints or grievance channel, such as a Peruvian university's "Libro de Reclamaciones", Brazilian ombudsman (ouvidoria) desks and Migori County's grievance portal in Kenya.

Sales signal: a vendor selling help desk add-ons or migration services in Spanish and Portuguese will find more of this list reachable than an English-only one.

Who leaves, and for what

We don't publish a switching corridor for osTicket: the 29 domains that dropped it since March are too few to show one. The like-for-like alternative is Zammad, also open source and usually self-hosted, on 553 domains to osTicket's 1,337. The hosted options are much bigger: Freshdesk has 5,487 domains in our Help Desk table, and Zendesk's profile counts 113,696.

"The likeliest threat to an osTicket desk is the day someone decides they're done running a server for it." - Sophie Clarke, Product Marketing Manager at TechnologyChecker.io

Sales signal: hosted help desks should lead on the time self-hosting takes, PHP upgrades and security patches included. SupportSystem, osTicket's own hosted edition, is the low-friction move for teams that want to keep the same software.

The stack next door

The tech stack on this page describes the organisation's main website, because osTicket sits on its own subdomain. WordPress runs on 50.72% of the 1,382 domains and Google Analytics on 49.2%. Elementor is on 18.89% and Joomla on 5.28%. Chat is rare: WhatsApp Business Chat is on 5.72% and Tawk.to on 4.56%. Consent banners are thin too, with CookieYes on 4.34% and Complianz on 3.98%.

Sales signal: these teams take support by email and ticket. Live chat and self-service tools have an open field here, and the WordPress main site is where they'd go.

What it costs

osTicket's FAQ (15 October 2026) calls it 100% free open-source software under the GPL. Enhancesoft earns from hosting, professional services and commercial support. SupportSystem, the hosted osTicket, costs $12 per agent a month on Basic, $16 on Standard and $24 on Premium, with a 30-day free trial. The current release is v1.18.4 from June 2026.

Sales signal: per-agent pricing is the comparison these buyers will make. A team with five agents pays $60 a month for hosted osTicket on Basic, and nothing to run it themselves.

Key takeaways

1. 1,337 live domains, and 96.31% of the 1,382 we fetched still served osTicket.

2. Almost every install sits on its own subdomain, usually support. or helpdesk.

3. Small technology firms make up most of the base; universities make up most of the big names.

4. Spanish- and Portuguese-speaking countries hold more matched companies (166) than the United States (152).

5. Low churn: 29 domains dropped it in seven months.
