In-app browser checker.
Which browser am I in?
Open this page from inside an app — a TikTok bio, an Instagram DM, a Facebook post — and it tells you which browser you're actually in, and how to get to Safari or Chrome from there.

The check
What this page sees
Your browser right now
Checking your browser…
Reads your browser's user agent. Some apps don't identify themselves, so a few in-app browsers look like a normal one. The result isn't sent anywhere.
Why it matters
An in-app browser isn't your browser
Apps such as TikTok and Instagram often open links in a browser view of their own. For reading, that's fine. For anything that needs your accounts, it can get in the way.
Sign-ins and passwords
The in-app browser may not share the sessions and saved passwords of Safari or Chrome, so you can land signed out.
Payment methods
Which wallet and card options a checkout offers can differ. If one you expect is missing, try your usual browser.
Downloads and files
Saving a ticket or a PDF can behave differently inside an app. Your usual browser is the reliable place for it.
For creators
See what your visitors see
Your link may open in a different browser for your audience than it does for you. Three minutes with two phones settles it.
- 01
Send yourself the page
Put openout.app/in-app-browser-checker in a DM, your bio or a story — wherever your audience would tap a link.
- 02
Tap it inside each app
Open it from TikTok, Instagram and anything else that sends you traffic, on an iPhone and an Android phone.
- 03
Read what it says
The checker names the in-app browser it recognises. That's the browser visitors with the same app, phone and settings are likely to land in.
Coverage
Apps the checker recognises
It uses the same detection as OpenOut's breakout flow: TikTok, Instagram, Facebook, Threads, LinkedIn, Pinterest, Reddit, Snapchat, X / Twitter, WeChat, LINE, KakaoTalk, Naver, Google app.
What happens inside each of them, and what OpenOut does on iPhone and Android, is on the supported apps page.
FAQ
Straight answers
How do I know if I'm in an in-app browser?
Open this page from the app you're curious about. The checker reads your browser's user agent and names the app if it identifies itself. Signs without a tool: the page has the app's own header or close button instead of Safari's or Chrome's address bar.
How do I get out of an in-app browser?
Look for an Open in browser option in the app's menu (often three dots) or share sheet. If there isn't one, copy the link and paste it into Safari or Chrome. Wording and position vary by app and version.
Is anything I do on this page stored?
The check runs in your browser and the result isn't sent anywhere. Like every page on this site, the visit itself may appear in anonymous page-view statistics.
Why does it say I'm in a normal browser when I opened it in an app?
Some apps don't identify themselves in the user agent, and some open links in a full browser tab rather than a built-in view. Both look like a normal browser from the page's side, so no checker can be certain in every case.
