Branch.io Alternatives for Indie Developers in 2026

Branch.io is the industry standard for mobile deep linking. It has no public rate card — paid plans require a custom quote and a sales contact — and prices based on monthly active users. For indie developers and small teams, that is not a realistic option. If you arrived from Firebase Dynamic Links, see Migrate to Flinku in 5 minutes or the wider Firebase Dynamic Links alternatives in 2026 roundup.

This guide covers the real alternatives available in 2026, what each one actually does, and which makes sense depending on what you are building.

Why Indie Developers Need a Branch Alternative

Branch.io was built for enterprise mobile teams with attribution budgets. Its feature set reflects that: paid ad attribution, Meta and Google campaign integration, dedicated account managers, and pricing that scales with MAU growth.

Most indie developers do not need any of that. What they need is:

Deferred deep linking so shared links still work after an App Store install. iOS Universal Links and Android App Links configured automatically. A Flutter, React Native, or other cross-platform SDK. Flat pricing that does not spike when the app grows. No sales calls or enterprise contracts.

The question is which tool covers this at a price that makes sense for a solo developer or small team.

The Alternatives

Flinku

Flinku was built specifically after Firebase Dynamic Links shut down in August 2025. It targets the same audience Branch ignores: indie developers who need production-grade deep linking without enterprise pricing.

Feature coverage is complete: deferred deep linking on all plans including free, iOS Universal Links, Android App Links, deepview pages, analytics, and SDKs for Flutter, iOS, Android, React Native, Unity, and Capacitor. All SDKs are open source.

Pricing is flat and click-based with no MAU fees. Free plan covers 300 links per month and 10k clicks per month. Paid plans start at $12 per month.

Flinku also includes password-protected links, scheduled links (activate at a specific date and time), link health monitoring, geo routing on all plans, and smart fallback chains.

Best for: Indie developers and small teams who want a complete Firebase Dynamic Links replacement at honest pricing.

ChottuLink

ChottuLink entered the market after the Firebase shutdown targeting the same gap. It offers deferred deep linking on all plans. Its docs list SDKs for iOS, Android, Flutter, React Native, Capacitor / Ionic, and Unity.

Pricing is MAU-based: free up to 25k MAU, $19 per month up to 100k MAU, $39 per month up to 1M MAU. This model is friendlier than Branch but still means your costs grow as your app grows. A viral moment or successful launch could push you into a higher tier unexpectedly.

Best for: Developers comfortable with MAU-based pricing.

Smler

Smler sells deep linking and install attribution on flat monthly plans. Deferred deep linking, unlimited clicks, unlimited re-engagement opens, and links that never expire are included on every plan, including Free. The free tier covers 25,000 attributed installs a month on one app, with 30-day analytics retention. Paid plans are Builder at $19 a month, Team at $49, Scale at $129, and Enterprise from $299. Custom domains and removing Smler branding start at Builder. Going over the attributed-install allowance is $1.50 per 1,000 rather than a hard stop. Pricing verified against Smler's public pricing page in August 2026.

Best for: indie teams who want deferred deep linking on a recurring free attributed-install allowance, billed on plan capabilities rather than MAU.

Trade off: custom domains and unbranded links start at Builder ($19 a month). Free is one app with 30-day analytics retention. Paid entry is $19, above Flinku's $12 starting price.

Building Your Own

Some developers build a redirect server, serve their own AASA and assetlinks.json files, and implement fingerprinting for deferred deep linking. This gives full control but requires maintaining SSL certificates, keeping association files up to date across App Store updates, building and maintaining the fingerprinting match logic, and handling analytics yourself.

The hidden cost is ongoing maintenance. Every iOS or Android update that changes Universal Link or App Link behavior requires you to investigate and fix it. For most indie developers, the time cost exceeds the money saved.

Best for: Teams with very specific requirements that no existing tool meets, or developers who enjoy the infrastructure challenge.

Feature Comparison

Entry price, pricing model, free-tier terms, and published SDK lists verified against each vendor's public pages in August 2026. Where a vendor does not publish a fact, the cell is "Not published" rather than a guessed No. Check current pages before deciding.

What Actually Matters for Indie Developers

No MAU pricing. The worst outcome when building an app is getting punished for growth. MAU-based pricing means a successful launch or a viral moment triggers an unexpected bill. Flat pricing lets you budget reliably.

Flutter and cross-platform SDK support. Most indie developers use Flutter, React Native, or similar cross-platform tools. A platform without a first-class SDK for your framework is not a real option regardless of pricing.

Deferred deep linking on the free plan. Testing deferred deep linking requires it to actually work during development. Flinku, ChottuLink, and Smler all include it on Free, so you can evaluate the match flow on a clean device install before paying. Read What is deferred deep linking? for how that match works after install.

Setup that does not require a sales call. If you cannot sign up and start building within 10 minutes, that is a problem. Indie developers do not have time for enterprise sales cycles.

Pricing Reality Check

At $12 per month, Flinku costs less than most developer tools. Branch has no published rate card; pricing requires a sales conversation, and entry points reported by buyers are well above typical indie budgets.

The question for any indie developer is not which tool has the most features. It is which tool covers your actual needs at a price that makes sense before your app generates revenue.

For most Flutter, React Native, and cross-platform developers, the answer is a flat-pricing tool with a working free tier, open source SDKs, and no MAU surprises.

Getting Started

Flinku has a free plan with no credit card required. Setup takes under 10 minutes: create a project, add your Bundle ID and Package Name, add the associated domain entitlement in Xcode or the intent filter in your AndroidManifest, and call Flinku.match() on launch.
