Deep Links vs Universal Links vs App Links
5 min read
Deep links, universal links, and App Links all open apps, but they behave differently — especially when the app is not installed. Understanding the difference helps you pick the right approach and set the right expectations.
Standard deep links
A standard deep link (often a custom URL scheme like twitter:// or an Android intent://) opens a specific screen in an app. If the app is not installed, the link can fail or do nothing, so a web fallback is important.
Universal Links (iOS)
Apple's Universal Links are regular https URLs that open the app when it is installed and fall back to the website when it is not. They require the app developer to verify domain ownership, which makes them seamless but developer-dependent.
App Links (Android)
Android App Links are the equivalent: verified https URLs that open the app directly without a chooser dialog. Like Universal Links, they need domain verification by the app owner.
Which should you use?
If you control the app, Universal Links and App Links give the cleanest experience. If you are a creator or marketer linking to apps you do not own (YouTube, Amazon, Instagram), a deep link generator with a web fallback is the practical choice — it opens the app where possible and the website otherwise.
