AppLinks

Master deep links and app links with a live testing playground

AppLinks is a niche yet extremely handy tool aimed squarely at developers who need to understand and debug Android application linking. Rather than being another everyday utility, it acts as an interactive companion to the official documentation, letting you experiment with how different URLs are resolved by installed apps.

The interface is intentionally minimal and functional. You paste or compose a URL, then AppLinks shows you which apps can handle it, how they respond, and what kind of intent is triggered. This makes it much easier to spot misconfigured intent filters, wrong hosts or paths, and other subtle mistakes that can break deep linking in production.

One of the strongest points of AppLinks is how it visualizes the decision process. Instead of guessing why a given link opens in a browser instead of your app, you can see the underlying rules in action. It’s particularly helpful when working with HTTP/HTTPS links, custom schemes, and verified app links, where behavior often varies between devices and OS versions.

Performance is snappy, and everything happens locally, so you can iterate quickly while editing your manifest or testing different link patterns. The app doesn’t try to do too much: it focuses on linking, does it well, and avoids clutter.

Its narrow scope is both a strength and a limitation. Non‑technical users will find little value here, and even some developers may wish for extras like persistent test suites or automated validation reports. Still, as a lightweight, always‑available reference and testing tool, AppLinks excels.

If you regularly work with deep links, web-to-app flows, or app links verification, AppLinks is a smart addition to your toolkit that can save you hours of trial and error.
