Picking a Firebase Dynamic Links alternative usually starts with a bug report: an invite link, a QR code on a flyer or a password-reset email that now lands on a 404. Google switched the service off on August 25, 2025, and every page.link URL has returned 404 ever since. Here is how to rebuild what it did with native, mostly free pieces, including the config and code for each.

Split the problem into three jobs

Dynamic Links bundled three features behind one URL. You rarely need to replace all three, so start by naming the ones your app actually relied on:

Routing : open the app on the right screen when it is installed, otherwise send people to a store or a web page.

Deferred deep linking : carry the link's context (an invite code, a product ID) through the install so the app can read it on first launch.

Short links and analytics : compact URLs, click counts and campaign parameters.

Google's own FAQ suggests the same split.…
