Have Firebase Dynamic Links stopped working?

Yes. As of August 25, 2025, Firebase Dynamic Links no longer resolve. Any existing links shared via email, social media, or QR codes are now broken. Migrating to ULink restores your deep linking functionality.

Is ULink compatible with Flutter?

Yes. ULink has a first-class Flutter SDK with an API surface designed to make migration from Firebase straightforward. Most developers complete the switch within a single sprint.

What happens if I exceed the free tier?

The free tier covers 10,000 monthly active users. If you exceed this, your links continue working — we'll notify you and you can upgrade to Starter ($19/mo) or Pro ($49/mo) at any time.

How does deferred deep linking work?

ULink uses device fingerprinting and install attribution to match users across the app install flow. When a user clicks a link, installs your app, and opens it — they're routed to the correct content automatically.

Can I use my own custom domain?

Yes. Custom domains are available on Starter and Pro plans. Use any domain you own (e.g., link.yourcompany.com) with full SSL and AASA hosting included.
