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.
