The Modern Firebase Dynamic Links Replacement

Yes. Google shut down Firebase Dynamic Links in August 2025, taking link creation, analytics, and deferred deep linking offline. Flinku covers the same core job: short links that route users to the right screen in your app, deferred deep linking that survives an App Store or Play Store install, and the apple-app-site-association and assetlinks.json files served and kept current for you automatically. Pricing is flat and published, based on links and clicks rather than monthly active users, so a viral week does not change your bill. Migration for most apps means configuring a project, swapping the SDK, and retesting on a clean device install.

A normal deep link only works if the app is already installed. Deferred deep linking handles the case where it is not. A user taps your link without having the app, gets sent to the App Store or Play Store, installs, and on first open still lands on the exact screen the link pointed at, along with any parameters it carried. Flinku does this by matching the install back to the original click. This is the part that most link shorteners skip, and it is usually where mobile conversion is lost, because a user who installs and lands on a generic home screen has forgotten what they tapped in the first place.

Most developers finish in under 30 minutes. The steps are: create a project in the dashboard, add your iOS bundle ID and Android package name, install the SDK from pub.dev, npm, JitPack, or CocoaPods depending on your platform, and call configure on app start followed by match to retrieve any pending deep link. Flinku generates and serves your apple-app-site-association and assetlinks.json files automatically, so there is no separate hosting step for Universal Links or Android App Links. Every link also gets a QR code with no extra setup. Full setup guides for each platform are at docs.flinku.dev.

Yes. Flinku publishes a native Flutter SDK on pub.dev as flinku_sdk, with full source available. Five other SDKs cover the rest of the mobile landscape: iOS in Swift, Android in Kotlin, React Native, Capacitor, and Unity. All six are open source, so when a deferred match behaves unexpectedly you can read the matching logic yourself rather than filing a ticket and waiting. The API surface is consistent across platforms, which matters if you ship the same product on more than one. Platform specific setup guides, including the iOS and Android configuration each one needs, are at docs.flinku.dev.

Yes, and it is available on every plan including Free rather than gated behind a paid tier. From SDK 0.6.0, Flinku attributes installs and qualified actions to the user who shared an invite link, and the attribution survives an App Store or Play Store install. The flow is: create links carrying a referrerId parameter, pass your publishable flk_pk_ key to configure, call setUserId after the new user signs up, and call qualifyReferral when they complete whatever action earns the reward. Qualification is optional, so an install alone still counts if that is the metric you care about. Full guide at docs.flinku.dev/docs/referral-system.

Nothing is deleted and nothing breaks permanently. If you pass your monthly click limit, links begin showing a temporary unavailable message instead of redirecting, and normal service resumes at the start of the next billing month or as soon as you upgrade. Your links, analytics history, projects, and configuration all stay intact. Upgrades take effect immediately, so if you hit the limit mid campaign you can raise it and have links working again straight away. Clicks are the metric that moves you between tiers, which means your bill tracks actual traffic rather than how many users your app happens to have that month.

Yes. Custom domains are available on the Growth and Studio plans. You add the domain in your project settings, create a CNAME record pointing to flku.dev, and Flinku verifies it and provisions the SSL certificate for you. Once it resolves, your links use your own branded domain instead of a flku.dev subdomain, and the apple-app-site-association and assetlinks.json files are served from your domain automatically so Universal Links and Android App Links keep working. Branded domains matter more than they look: users are measurably more willing to tap a link on a domain they recognise, particularly when it arrives through messaging apps.

There is no time limited trial because the Free tier does that job without an expiry date. It includes 3 projects, 300 links, and 10,000 clicks per month, with deferred deep linking, QR codes, analytics, and the referral system all included rather than held back for paid plans. Evaluate for as long as you need. Paid tiers are Indie at $12 a month, Growth at $24, and Studio at $39, each available monthly or annually, with annual billing priced at ten times the monthly rate so two months are free. No credit card is required to start on Free.

Cancel anytime from your dashboard settings. There are no cancellation fees, no retention flow, and no need to contact support. Your paid plan stays active until the end of the period you have already paid for, so annual subscribers who cancel partway through keep paid features until the annual date. After that the account moves to the Free tier rather than being closed. Nothing is deleted: your projects, links, and analytics history stay intact, and every existing link keeps resolving even if you are over the Free tier link limit. You simply cannot create new links until you are back under it, and the 10,000 monthly click limit applies. If you were using a custom domain, it stays active for a 14 day grace period after downgrade, and you will get an email before it is removed. Resubscribing at any point during that window keeps it in place.
