14 app signatures.
Know what detection means.
This list describes OpenOut's detection rules. It is not a device test matrix or a guarantee that a browser switch will succeed. Use it to understand coverage, then test the actual journey your visitors take.
- Known app markers
- Limited generic detection
- Copying and manual guidance
The list
Apps OpenOut detects by name
A matching marker lets OpenOut name the context. Missing or changed markers can produce a different result; test the app version your audience uses.
| App | Notes |
|---|---|
| TikTok | Test from the actual TikTok link placement on both iPhone and Android. |
| Check bio links, story links and messages separately on your audience's devices. | |
| Groups recognised Facebook-family markers; test Messenger and Marketplace separately. | |
| Threads | Has a separate detection rule evaluated before the Facebook-family rule. |
| Test the sign-in, booking or lead form at your actual destination. | |
| Check the destination reached from the pins your audience uses. | |
| A recognised Reddit marker does not establish support for every third-party client. | |
| Snapchat | Test your actual shared link and destination on the installed app version. |
| X / Twitter | Matches specific app markers rather than any mention of the website. |
| Check detection, opening attempts and manual continuation on the actual device. | |
| LINE | Test the shared link from a conversation, including the manual fallback. |
| KakaoTalk | Check a real shared-link journey; a named match is not a verified browser switch. |
| Naver | Matches the in-app marker; other Naver browsing products are not implied. |
| Google app | Matches the Google app marker; this does not classify all Google search traffic. |
Choose your test devices from actual audience traffic. Record the source app, OS, version, date, browser that opened and destination reached. A detector match alone does not cover those outcomes.
The catch-all
What generic detection can miss
A named list is never complete. Apps ship new builds, change their tokens and appear from nowhere, so a detector that only knew a fixed set of names would silently stop working for the next one.
Beyond named matches, generic markers can identify some unnamed in-app browsers. Those contexts are reported as unnamed rather than assigned an app name that the detector cannot establish.
An app can omit those markers. Treat unknown contexts as unknown, and include missed detections and unnecessary prompts in your own testing instead of assuming every visit was classified correctly.
What happens next
The same detection, three different responses
Knowing which app a visitor is inside is only useful if the next step suits the platform. What is possible differs sharply between iOS and Android, and pretending otherwise is how tools end up promising an automatic escape they cannot deliver.
Android — intent hand-off
OpenOut can offer an intent-based opening attempt after a visitor taps. Whether another browser opens depends on the source app, device and configuration. Copying and manual instructions remain available.
iOS — guided flow
OpenOut emphasises browser instructions and a copyable continuation link. Visitors open their preferred browser and paste the link; if clipboard access is blocked, they can select it manually.
Desktop and everything else
A visitor already using a normal browser does not need to leave it. When a detected in-app context needs guidance but its platform is unclear, a generic guide provides the manual steps.
If the handoff does not happen, visitors get a copyable continuation link and instructions for pasting it into their own browser. When clipboard access is blocked, the URL remains visible for manual selection. App menus, clipboard permissions and browser behavior vary; test the devices your audience uses.
What this page will not claim
Detection is not a successful browser switch
OpenOut does not guarantee automatic browser opening, destination arrival or a purchase. Those are separate outcomes to verify.
Test from a link inside the actual social app. Opening a QR code directly in Safari or changing a desktop user agent can help inspect the interface, but neither demonstrates a real app-to-browser handoff. Measure any effect on conversion separately; this catalog supplies no conversion uplift evidence.
FAQ
Straight answers
Which apps open links in an in-app browser?
OpenOut has named detection rules for 14 app signatures: TikTok, Instagram, Facebook, Threads, LinkedIn, Pinterest, Reddit, Snapchat, X / Twitter, WeChat, LINE, KakaoTalk, Naver, Google app. This is a detector inventory, not proof that every version opens every link inside the app. Recognised Facebook-family markers are grouped under Facebook rather than separate Messenger and Marketplace entries.
What happens with an app that isn't on the list?
Generic markers can identify some unnamed webviews as "other". Not every webview exposes those markers, so an unmarked context may go undetected. The flow also depends on your enabled breakout settings; an unknown app is not automatically a verified supported device.
Can I turn the breakout off for specific apps?
Yes, at three levels of granularity: TikTok, Instagram and everything else. So you can leave breakout on for TikTok while letting Instagram traffic through untouched, or disable it everywhere without deleting the configuration.
Does breakout work the same on iPhone and Android?
No. OpenOut can offer an intent-based attempt on Android, while iPhone guidance emphasises copying and manual opening. Test the real source app and destination on each device. Recognising a browser does not prove that an opening attempt succeeded.
How does detection actually work?
OpenOut matches known markers in the user-agent string and uses configured heuristics for some other contexts. Server and client checks inform the flow. These signals can be absent or misleading, and detection coverage changes when apps change their markers.
Can detection be wrong?
Yes. False positives can show guidance where it is unnecessary; false negatives can miss an in-app visit. Copying and manual selection help visitors continue once the guide is shown, but they do not make detection infallible or guarantee destination arrival.
