AdminKit vs WhatIsMyBrowser.com: User-Agent parsing
WhatIsMyBrowser.com's own homepage says it decodes a visitor's User-Agent string to show "what browser, operating system and device you are using," and sells a separate User Agent Parsing API with paid tiers from 5,000 free detections a month up to $99 AUD/month for 1,000,000 (whatismybrowser.com, developers.whatismybrowser.com/api/pricing/, read 2026-10-29); AdminKit's User agent tool shows the same kind of browser/OS/device breakdown for free with no account, parsed entirely client-side with no API product today.
What each tool actually shows
Per WhatIsMyBrowser.com’s own homepage, read 2026-10-29, its detect widget reads the User-Agent header your browser sent and states it has “decoded it to figure out what browser, operating system and device you are using.” Its detect page shows the raw User-Agent string directly, with no sign-in required anywhere on the page. AdminKit’s User agent tool shows the same kind of result — raw string plus a browser/OS/device breakdown — with one concrete difference its own tool page states plainly: the parsing happens entirely in your browser via navigator.userAgent, with no server round trip, whereas reading a User-Agent header on a page load is inherently server-visible for any site, WhatIsMyBrowser.com included.
Where WhatIsMyBrowser.com goes further is as a developer product: per its API pricing page, read 2026-10-29, the User Agent Parsing API offers a free Basic tier (5,000 monthly browser detections) and three paid tiers — Standard ($25 AUD/month, 50,000 detections), Pro ($50 AUD/month, 250,000 detections), and Enterprise ($99 AUD/month, 1,000,000 detections) — plus a separate exploration platform at explore.whatismybrowser.com for browsing known user-agent strings by browser, OS or device. AdminKit’s User agent tool has no API product or research-platform equivalent today.
A transparency note on WhatIsMyBrowser.com’s parse-result page
This comparison could not independently verify the exact output fields on WhatIsMyBrowser.com’s dedicated parse-result page (explore.whatismybrowser.com/useragents/parse/) — every attempt to load it at verification time (2026-10-29) returned an HTTP 502 server error. The facts above about its decoding capability and API pricing come from pages on whatismybrowser.com and developers.whatismybrowser.com that did load successfully, each linked above so it can be checked directly. This page does not claim WhatIsMyBrowser.com’s parser is more or less detailed than AdminKit’s beyond what those pages state.
The honest angle
This isn’t a claim that AdminKit replaces a hosted parsing API for developers who need to classify traffic at scale — WhatIsMyBrowser.com’s paid tiers are built for exactly that, with quotas up to a million detections a month. AdminKit’s User agent tool is a free, one-off, client-side check for a single visitor to see what their own browser is telling every site, with no account, no API, and nothing sent to AdminKit’s servers.

Frequently asked questions
Does WhatIsMyBrowser.com require an account to see your User-Agent breakdown?
No. Its detect page shows your raw User-Agent string and a short decoded description with no sign-in mentioned anywhere on the page. AdminKit's User agent tool also requires no account.
Does WhatIsMyBrowser.com offer a paid API, and what does it cost?
Yes. Per developers.whatismybrowser.com/api/pricing/, read 2026-10-29, the User Agent Parsing API has a free Basic tier (5,000 monthly browser detections) and three paid tiers: Standard at $25 AUD/month (50,000 detections), Pro at $50 AUD/month (250,000 detections, marked "Popular!"), and Enterprise at $99 AUD/month (1,000,000 detections). AdminKit's User agent tool has no API product today.
Does AdminKit's User-Agent parser run server-side like WhatIsMyBrowser.com's API?
No. AdminKit's own tool page states parsing happens entirely in your browser using navigator.userAgent, with nothing sent to AdminKit's servers. WhatIsMyBrowser.com's detect page reads the User-Agent header your browser sends with the request (necessarily server-visible for any site), and its separate API product is an explicitly server-side, hosted parsing service by design.
Could WhatIsMyBrowser.com's parser be more accurate than AdminKit's?
Unverified either way. WhatIsMyBrowser.com's own pages describe a dedicated User Agent exploration platform and market their API as "the best user agent parsing API on the net," but this page could not independently load WhatIsMyBrowser.com's parse-result page (explore.whatismybrowser.com returned a server error on every attempt at verification time) to compare specific output fields against AdminKit's breakdown, so this page does not claim either tool is more accurate.
Does this page use WhatIsMyBrowser.com's logo or brand assets?
No. WhatIsMyBrowser.com is referred to by name only (nominative use) to describe and compare publicly available tools. AdminKit is not affiliated with or endorsed by WhatIsMyBrowser.com.
