Deep Link Tester

The developer tool for everything deep linking on Android: fire any link, see exactly what happens, and find out why it doesn't.

TEST ANY LINK

• Type or paste a URL, custom scheme, or full intent:// URI

• Live, color-coded breakdown: scheme, host, path, query parameters, fragment

• Instant warnings for the classic mistakes — missing scheme, unencoded spaces, duplicate query keys, missing browser fallback

• See every app that can handle the link, with the current default marked

• Launch into the default handler, the system chooser, or one specific app

• Honest results: which app opened, or exactly why nothing did

DISSECT INCOMING LINKS

• The app registers its own deeplinktester:// scheme — point any link at it

• Every incoming intent is captured in full: action, data, categories, referrer, flags, and all typed extras

• Share a link from any app straight into the tester

BUILD LINKS VISUALLY

• Assemble scheme, host, path, query parameters and fragment field by field

• Correct percent-encoding applied automatically

VERIFY YOUR SETUP

• Fetch and validate a domain's assetlinks.json and apple-app-site-association

• Query Android's own domain verification state for any installed app — pm get-app-links, without the cable

• Scan 30+ well-known URI schemes and see which apps answer them

HANDY EXTRAS

• QR code for opening a link on another device

• Copy a ready-made, correctly quoted adb command

• Template catalog: system, social, media, navigation and edge-case links

• History, inbox and saved links with JSON export

• Light and dark themes, 15 languages

PRIVATE BY DESIGN

The links you test never leave your device. History, saved links and the inbox are stored locally.
