}Yes. Firebase shut down Dynamic Links in August 2025. Flinku provides the same deferred deep linking functionality with a simple API, flat pricing, and SDKs for Flutter, iOS, and Android.
Deferred deep linking means that if a user clicks your link but doesn't have the app installed, they get sent to the App Store or Play Store. After they install and open the app, they still land on the correct screen - as if they never left.
Most developers complete integration in under 30 minutes. Every link automatically gets a QR code — no extra setup needed.
Yes. Flinku has a native Flutter SDK available on GitHub. iOS (Swift) and Android (Kotlin) SDKs are also available.
Links that exceed the click limit for the month will show a temporary unavailable message. You can upgrade your plan anytime to increase limits.
Yes. Custom domains are available on the Studio plan. Add a CNAME record pointing to flku.dev and your links will use your own branded domain.
Yes. The free plan is free forever with 3 links and 1k clicks/month. Paid plans include a 7-day free trial.
You can cancel anytime from your dashboard settings. No cancellation fees, no questions asked.
