Companies Using Atlassian

Atlassian Usage Statistics

How has Atlassian usage changed over time? The series reads 118,250 active domains in June 2026, 131,475 in July, 133,558 in August and 140,482 in September. Read that as coverage rather than adoption. The June to July step is 11.18% in one month, and our crawled corpus expanded sharply across the same window, so a rule that had always matched these domains simply began to see more of them. Four points in a single crawl window cannot carry a growth rate.

One caution belongs on this profile more than most. The signal is a DNS verification record that outlives the account which created it, so a domain that enters this series has very little mechanism for leaving it. Total domains seen ran 118,250 in June and 141,517 in September against an active line of 140,482, a gap of only 1,035 domains. A series that can essentially only move upwards should never be read as momentum. The September figure, 140,482, is the one quoted at the top of this page.

Which Countries Use Atlassian the Most?

Which countries use Atlassian the most? The United States leads on 38,538 companies, 40.68% of the 94,740 held by the fifteen countries shown. Germany is second on 10,781 and the United Kingdom third on 9,667, then Australia fourth on 6,345, ahead of Canada on 4,589. Australia sitting above Canada is a home-market signal that very few vendor profiles on TechnologyChecker.io produce, and it is the sort of detail a verification record records well, because it is set at the corporate apex by the company itself.

The European rows are heavy: the Netherlands 4,337, France 3,379, Switzerland 3,064, Spain 2,385, Sweden 1,792, Belgium 1,652, Poland 1,594 and Italy 1,531, with Switzerland ahead of India's 2,745 despite a population difference of two orders of magnitude. That is what a base of engineering-led organisations looks like. Two caveats: country is the headquarters on the enriched company record, not where anyone opens Jira, and a group that verifies one apex appears once rather than once per subsidiary.

Atlassian Market Share Among Productivity & Collaboration

What is Atlassian's market share? Atlassian ranks 1st of our Productivity & Collaboration category on 35.41% share, from 140,482 domains. That is the position, and it needs one qualification to be quoted safely: it is a lead in domains carrying an Atlassian verification record, which is not the same claim as a lead in usage. A record published once in DNS accumulates and does not expire; whether the software behind it is in daily use, or was retired three years ago, is invisible to this rule.

The rows below it are Zoom on 46,664 domains (11.76%), DocuSign on 39,558 (9.97%), Kakao on 36,581 (9.22%), Webex on 27,560 (6.95%) and Slack on 20,844 (5.25%). Atlassian's count is 3.01 times Zoom's, and all five together reach 43.15% against Atlassian's 35.41%. One further disclosure belongs here: a second row in our detection dictionary, Statuspage, carries a byte-identical rule, the same atlassian-domain-verification string. Statuspage is filed under Help Desk rather than this category, so it does not double-count inside the 35.41%, but the same domains are counted under two names elsewhere in the corpus.

Atlassian Customers by Company Size & Age

What size companies use Atlassian? Mid-market, and more evenly spread than the named table suggests. The largest band is 11-50 employees on 34,965 of the 120,618 companies with a size band, 28.99%, then 51-200 on 29,985 (24.86%) and 1-10 on 23,794 (19.73%). Add those three and 88,744 companies, 73.57%, employ fewer than 200 people. Above them sit 12,867 at 201-500 (10.67%), 6,755 at 501-1,000 (5.60%), 8,130 at 1,001-5,000 (6.74%), 1,720 at 5,001-10,000 (1.43%) and 2,402 at 10,001+ (1.99%), so 12,252 companies, 10.16%, employ more than a thousand.

Now set that against the named list further down, where 49 of the 50 rows are in the largest band. That list is ordered by prominence, so it shows the top of the base rather than its centre. The centre is a company of twenty to a hundred people that signed up, verified its domain so that accounts could be provisioned against company email, and has left the record in place ever since. Both facts are true at once: nearly every very large enterprise you can name is here, and three quarters of this list is under 200 people.

What Industries Use Atlassian the Most?

Which industries use Atlassian? Technology, decisively. IT Services and IT Consulting leads on 16,441 companies, 13.90% of the roughly 118,300 with a recorded industry, with Software Development almost level on 16,133 (13.63%). Our industry taxonomy carries a second, older IT label as well, so the honest way to total the cluster is to add Technology, Information and Internet on 5,817 (4.92%) and Information Technology & Services on 3,783 (3.20%), giving 42,174 companies, 35.65%, in technology. Financial Services follows on 6,895 (5.83%), then Advertising Services 3,046 (2.57%), Hospitals and Health Care 2,644 (2.23%), Insurance 2,230 (1.88%), Business Consulting and Services 2,141 (1.81%) and Retail 1,855 (1.57%). A tool bought by software teams shows up as a list of software companies.

Which kinds of organisation verify a domain with Atlassian? Software and IT firms using Atlassian are the core at 35.65% of companies with a recorded industry once the four technology labels are combined, which is unusually concentrated for a category this size. Financial services firms on Atlassian are the largest non-technology vertical at 6,895 companies (5.83%), with Insurance adding 2,230 (1.88%), and regulated industries are exactly where domain verification is most likely to be completed as policy rather than as an afterthought. Healthcare organisations using Atlassian account for 2,644 (2.23%). One structural note on all of these: the verification record is published at a corporate apex, so what the industry table really describes is the organisation that owns the domain, not the team inside it that opens Jira. A bank appears as a bank whether the record was set up by its platform engineering group or by its IT service desk.

Atlassian Alternatives & Competitors

Who are Atlassian's competitors here? This table lists the largest technologies filed in the same category, which is not the same as the products a buyer weighs against Jira or Confluence. Zoom sits on 46,664 domains (11.76%), DocuSign on 39,558 (9.97%), Kakao on 36,581 (9.22%), Webex on 27,560 (6.95%) and Slack on 20,844 (5.25%), all below Atlassian's 140,482 and 35.41%. Look at what those products do: two are video conferencing, one is electronic signature, two are messaging. Nobody chooses between an issue tracker and an e-signature service, so this is a shelf of things filed together rather than a shortlist.

There is no switching table on this page, and that is a decision rather than a gap. The structural reason is stronger than the numeric one. A verification record survives the account that created it, because DNS is not pruned when a subscription lapses, so a company that left Atlassian years ago usually still carries the record, still appears in this data and never registers as a departure at all. Only 1,154 domains have ever stopped matching. This rule measures arrival well and departure barely, and a switching table built on it would be reporting the wrong end of the relationship.

There is one respect in which the column is a fair comparison, and it is worth stating because it cuts against how these tables usually work. Every major entry here is detected the same way Atlassian is — by a DNS TXT verification record. Zoom publishes ZOOM, DocuSign docusign, Webex cisco-ci-domain-verification, Slack slack-domain-verification, Miro miro-verification, Notion notion-domain-verification, 1Password 1password-site-verification. Several have no other clause at all. So this category is not measuring installed software against installed software, nor mixing surfaces: it is a consistent map of which SaaS vendors a domain has been verified with. Read as that, the ranking holds. Read as a usage ranking, none of it does.

Technology	Domains	Market Share
Zoom	46,664	11.76%
DocuSign	39,558	9.97%
Kakao	36,581	9.22%
Webex	27,560	6.95%
Slack	20,844	5.25%

Tech Stack of Atlassian-Powered Websites

What else runs on domains verified with Atlassian? Every percentage below divides by roughly 141,400 domains, the live set the overlap query ran against, which is a slightly different base from the 140,482 in the September rollup. Before reading any of it, note what these rows can and cannot describe. The verification record sits on a company's own apex, while Jira and Confluence are served from Atlassian's own hosts. This table therefore describes the company's public website, not its Atlassian instance.

That explains the front-end rows, which are older than the customer base would suggest: jQuery on 93,933 domains (66.41%), core-js on 74,265 (52.50%), jQuery Migrate on 44,480 (31.45%), Swiper on 34,755 (24.57%) and jQuery UI on 31,711 (22.42%). A jQuery Migrate share of 31.45% is a marketing site carrying a compatibility shim for code written years ago, which tells you about the corporate web estate rather than about the engineering team that bought Jira. Cloudflare on 70,620 (49.93%), jsDelivr on 25,231 (17.84%) and cdnjs on 21,985 (15.54%) are the same picture from the delivery side, and Google Analytics on 91,327 (64.57%) is close to universal.

The mail group is the interesting one, and it needs care. Microsoft 365 reads 67,592 domains (47.79%), Apple iCloud Mail 44,229 (31.27%) and Google Workspace 34,839 (24.63%). Those three sum to 103.69%, so they cannot be read as a split of one mail market; domains carry more than one of these signals at a time, and the rows overlap rather than competing. What the group does show is that the domains on this list are corporate apexes with real mail on them, which is consistent with a record that only an organisation controlling its own DNS can publish.

Atlassian Customer Reviews with Pros and Cons

What do users say about Atlassian? One scoping note first: the reviews we aggregate here are for Confluence specifically, one product in a suite this page cannot break apart, so they are evidence about Confluence rather than about the 140,482 verified domains. Across them, ease of use leads with 304 mentions, followed by team collaboration (213), organisation through spaces and page hierarchies (160), integrations with Jira, Trello and the Marketplace (158) and collaboration efficiency (147). The complaints are consistent and specific: a steep learning curve for non-technical users (89), inconsistent search (67), performance on large spaces (52), per-user pricing that escalates as teams grow (48) and editor limitations (41). That is 982 positive mentions against 297 negative.
