Companies Using Postman API Documentation

Postman API Documentation Usage Statistics

We read 5,330 domains on the June 2026 rollup, 5,991 in July and 6,068 in August. Three points cannot carry a growth rate, and this movement is coverage rather than adoption. Across the whole crawl, active detections went from 321.0M in June to 352.2M in August, a 9.7% widening of what we can see. The marker makes the point sharper than usual: most of these matches are a DNS TXT record that was published once and never removed, so a domain entering this series means we resolved its DNS for the first time, not that a team signed up in July. A rising line here is our coverage catching up with a population that was already there. The August figure, 6,068, is the one quoted at the top of this page.

Which Countries Use Postman API Documentation the Most?

Which countries use Postman API Documentation the most? The United States holds 2,146 of the 5,006 companies we could place, 42.87%, and the United Kingdom is second on 399, 7.97%. The interesting part is third: Brazil at 232 companies, 4.63%, ahead of Australia (196, 3.92%), Canada (193, 3.86%) and India (187, 3.74%), with Germany (141, 2.82%) and France (128, 2.56%) behind them. Netherlands 1.92%, Spain 1.5%, Singapore 1.12%, Mexico 1.08%, Switzerland 1.04% and Italy 0.96% fill out the chart. The fourteen countries shown cover 4,003 of the 5,006 located companies, 79.96%, which leaves 1,003 companies, 20.04%, outside them entirely, and 2,860 of the total, 57.13%, outside the United States. Named non-US detections match that spread: Infosys in India, PwC in the United Kingdom, AXA, Danone and L'Oréal in France, SAP in Germany, Zurich, Chubb and Philip Morris International in Switzerland, Desjardins in Canada, Mercadolibre in Argentina and MTN Group in South Africa.

Postman API Documentation Market Share Among Documentation & Knowledge Base

What is Postman API Documentation's market share? It holds 3.49% of Documentation & Knowledge Base and ranks 4th in that category on 6,068 domains. Zendesk leads on 111,482 domains and 64.05%, then Foxit (8,700, 5.0%), MediaWiki (6,097, 3.5%), this row, Docusaurus (5,507, 3.16%) and Open Journal Systems (5,253, 3.02%). Two things to hold before quoting the rank. First, the gap between third and fourth is 29 domains, which is inside the month-to-month movement of a rollup this size, so treat 3rd and 4th as a tie. Second, the rows are not measured on the same surface: Zendesk help centres, MediaWiki and Docusaurus are read from the page a visitor loads, while 96.6% of the detections counted here are read from DNS at the apex domain. A share built that way counts domains carrying a detectable marker, not spending, seats or documentation traffic.

Postman API Documentation Customers by Company Size & Age

What size companies use Postman API Documentation? This is the table that defines the page. 11-50 employees is the largest band at 1,826 of the 5,116 companies that report a headcount, 35.69%, with 51-200 second at 1,028, 20.09%, and 1-10 third at 1,018, 19.9%. Added up, 2,844 companies, 55.59%, employ fewer than 50 people and 3,872, 75.68%, employ fewer than 200. At the other end, 585 companies, 11.43%, employ more than 1,000 and only 175, 3.42%, sit in the 10001+ band. Counted on domains rather than companies, 162 of the 6,068, 2.67%, belong to organisations with 8,000 or more employees. Read that against the named list further down, which is Deloitte, Infosys, PwC, Citigroup and Ford. Those names are real detections, but they are drawn from the 3.42% tail because the list is ordered by audience size, not by how typical a company is. The centre of this distribution is a team of fewer than fifty people.

What Industries Use Postman API Documentation the Most?

Software Development leads at 1,276 of the 5,063 companies with a recorded industry, 25.2%, more than twice Financial Services in second at 587, 11.59%, with IT Services and IT Consulting third at 534, 10.55%, and Technology, Information and Internet fourth at 449, 8.87%. Group the related labels and the concentration is plain: software, IT services, internet, the separate Information Technology & Services label (161, 3.18%) and computer and network security (50, 0.99%) together are 2,470 companies, 48.79%, close to half the industry-tagged base. Money is the second cluster, with financial services, insurance (156, 3.08%) and banking (64, 1.26%) at 807 companies, 15.94%. Telecommunications (107, 2.11%), transport and logistics (101, 1.99%), health care (83, 1.64%) and advertising services (70, 1.38%) trail behind. The twelve labels charted cover 3,638 companies, 71.85%. Worth knowing before you quote a single row: IT Services and IT Consulting and Information Technology & Services are two labels for much the same thing and total 695 companies, 13.73%, between them.

Software companies using Postman API documentation are the single largest block at 25.2% of the 5,063 companies with a recorded industry, and that is the row doing the most work on this page: a software company publishes an API, an API needs documentation, and a workspace gets verified against the domain. SAP, Adobe and Cisco carry that label in the named list. Banks and insurers using Postman API documentation are the second cluster at 15.94% across three labels, and the reason is specific rather than general digital adoption: open banking and payments programmes publish partner-facing endpoints, and Citigroup, Fidelity Investments, Desjardins, AXA, Zurich, Chubb and Progressive all appear on their apex domains. Telecommunications at 2.11% and transport and logistics at 1.99% read the same way, with Spectrum, MTN Group and UPS on the list. Health care at 1.64% and advertising services at 1.38% are thin by comparison. One caution on the labels themselves: they come from the company record, not from us, and they are sometimes wrong at the row level. Schlumberger is filed here under Technology, Information and Internet, which is not what that business does. Use the clusters, not the individual rows.

Postman API Documentation Alternatives & Competitors

Documentation & Knowledge Base is a category whose members are counted on different surfaces, so the table needs reading twice. Zendesk leads on 111,482 domains and 64.05%, an order of magnitude clear of everything else, because a hosted help centre leaves a marker on every customer site that serves one. Foxit follows on 8,700 domains and 5.0%, then MediaWiki (6,097, 3.5%), this row (6,068, 3.49%), Docusaurus (5,507, 3.16%) and Open Journal Systems (5,253, 3.02%). The distance between third and fourth is 29 domains, so the ordering there is a coin flip on any given month. The comparison that actually matters is not the ranking but the mechanism: MediaWiki, Docusaurus and Open Journal Systems are self-hosted publishing software found in the page a visitor loads, Zendesk is a hosted service found the same way, and this row is mostly a DNS record proving an account exists. Those are not measurements of the same thing. A company can appear in this row and in a Docusaurus count at the same time, and roughly one detection in thirty here, 3.4%, is the only part read from a documentation site at all.

Postman API Documentation Customer Migration

There is no switching table here, and the reason is not that the corridors came back empty. They returned counts: 23 domains show a corridor from Zendesk into this row. We suppressed it because it fails the test we apply before publishing any migration figure, which is whether the two technologies do the same job for the same buyer. A hosted help centre serving support articles to customers is not a substitute for published API docs and a verified workspace, and the two are read off surfaces that cannot be lined up, one from the page and one from DNS. A domain that shows both signals has almost certainly changed neither. Publishing 23 as a switching trend would invent a story the data does not contain. The churn figure beside it needs the same discipline: 74 domains have dropped this detection since we began tracking in March 2026, 1.22% of the 6,068 counted here, and that number is close to meaningless as a retention signal. Nobody deletes a DNS TXT record when they stop using a product. Low churn here measures the persistence of the marker, not the loyalty of the customer.

Tech Stack of Postman API Documentation-Powered Websites

Read this table as a list of other things these companies have verified a domain against, not as what they run at request time. That is what a DNS-matched population produces: Google Workspace appears on 42.68% of these domains and Atlassian on 34.72%, both of which are themselves account markers rather than page signals, and Atlassian is absent from the table above only because we hold no icon for it. The rest divides into measurement and delivery. Google Tag Manager at 73.76% and Google Analytics at 71.14% are the marketing team's own tags. Cloudflare at 63.95% and Amazon Web Services at 35.09% are where the site is served from, and Google Font API at 53.98% and Priority Hints at 50.18% are ordinary front-end hygiene. The front-end rows are the only ones with a mild signal in them: Tailwind CSS at 38.74% sits above Bootstrap at 30.62%, which is not the ordering you see on a general population of company websites, and it is consistent with a base that is half software and IT firms. Treat it as consistent with, not proof of. What is notably absent is a vendor fingerprint. Nothing here sits at 99% the way a hosted platform's own build sheet does, because the marker is a DNS record and the website beside it is whatever the company happened to build. Co-occurrence is measured across the 6,247 domains our live crawl currently answers for, a slightly wider set than the 6,068 in the August rollup, so a percentage in this table divides by 6,247.
