Answer: Which Should You Pick?
If you want the short answer: RevenueCat is the right default for most indie Flutter developers in 2026. It has a more mature Flutter SDK, a larger community (10,000+ apps), battle-tested documentation, and a free tier that covers you until $2,500/month in revenue. Adapty is a strong alternative if you want a more generous free tier (up to $10K MTR) and built-in no-code paywall templates with advanced A/B testing. Both are excellent products — but RevenueCat's ecosystem depth gives it the edge for most use cases.
Now let me walk you through the full comparison so you can decide for yourself.
The Subscription SDK Landscape in 2026
Managing subscriptions on mobile is hard. You are dealing with two entirely different payment systems — Apple's App Store and Google Play — each with their own receipt formats, validation APIs, grace periods, billing retry logic, and edge cases. Building this yourself in a Flutter app means maintaining two parallel codebases for purchase handling, writing your own server-side receipt validation, building an entitlement system, and handling dozens of lifecycle events like renewals, cancellations, refunds, and billing issues.
That is why subscription management SDKs exist. They abstract the platform differences behind a single API, validate receipts server-side, track subscriber status across devices, and give you analytics out of the box. The two leading options for Flutter in 2026 are RevenueCat and Adapty.
I have integrated both in production Flutter apps. Here is what I actually think after shipping with each one.
RevenueCat: The Established Standard
RevenueCat was founded in 2017 and has grown into the dominant subscription infrastructure platform for mobile apps. Over 10,000 apps use RevenueCat, processing billions of dollars in revenue. Their Flutter SDK (purchases_flutter) has been available since 2019 and is actively maintained with regular releases.
Key Features
- Server-side receipt validation for both App Store and Google Play — you never handle raw receipts in your Flutter code.
- Entitlements system that works across platforms — check
customerInfo.entitlements["pro"]and it works identically on iOS and Android. - Offerings — remote product configuration that lets you change which products are displayed without an app update.
- Real-time analytics dashboard with MRR, churn, cohort retention, trial conversion, and LTV charts.
- Experiments — server-side A/B testing for pricing and offerings with statistical significance reporting.
- Webhooks for every subscription lifecycle event, making it easy to sync subscriber status to your backend.
- Charts and integrations — connects to Amplitude, Mixpanel, AppsFlyer, Adjust, Slack, and more.
RevenueCat Pricing
RevenueCat is free until you reach $2,500 in monthly tracked revenue (MTR). The free tier includes full analytics, webhooks, and experiments — nothing is locked behind the paywall. Once you exceed $2,500 MTR:
- Starter (Free): Up to $2,500 MTR. Full feature access.
- Pro ($120/month): Up to $12,500 MTR. Priority support, advanced integrations.
- Scale (1.5% of MTR): Unlimited revenue. Dedicated support, custom webhooks.
- Enterprise: Custom pricing for large-scale apps.
Adapty: The Feature-Rich Challenger
Adapty launched in 2020 and has carved out a strong position by focusing on paywall experimentation and no-code paywall building. While smaller than RevenueCat in total app count, Adapty has attracted developers who want more built-in paywall tooling without relying on third-party paywall builders.
Key Features
- Server-side receipt validation for App Store and Google Play — same core functionality as RevenueCat.
- No-code Paywall Builder — design and deploy paywalls from the Adapty dashboard without writing Flutter code or pushing app updates. This is Adapty's standout feature.
- Advanced A/B testing — test not just pricing but entire paywall designs, layouts, and copy remotely.
- Placement-based paywalls — show different paywalls at different points in the user journey, all configured server-side.
- Analytics dashboard with revenue, conversion funnels, cohort analysis, and paywall performance metrics.
- Cross-platform SDK — supports Flutter, iOS, Android, React Native, and Unity.
- Webhooks and integrations — connects to Amplitude, Mixpanel, AppsFlyer, Adjust, and more.
Adapty Pricing
Adapty has a more generous free tier but a different pricing model at scale:
- Free: Up to $10,000 MTR. Core analytics, basic paywall builder.
- Pro ($199/month): A/B testing, advanced analytics, custom paywalls, up to $100K MTR.
- Enterprise: Custom pricing. Full feature access, dedicated support.
The Big Comparison Table
Here is a side-by-side across every dimension that matters for Flutter developers:
| Dimension | RevenueCat | Adapty |
|---|---|---|
| Free tier limit | $2,500/month MTR | $10,000/month MTR |
| Paid plan starting price | $120/month | $199/month |
| Revenue share (at scale) | 1.5% of MTR | ~1% of MTR |
| Flutter SDK maturity | Mature — maintained since 2019, stable API | Good — newer but actively maintained |
| No-code paywall builder | Basic — server-driven paywall templates (newer feature) | Advanced — full drag-and-drop paywall editor |
| A/B testing | Pricing and offering experiments | Pricing, offerings, and paywall design experiments |
| Analytics depth | Excellent — MRR, churn, cohorts, LTV, funnels | Good — similar metrics, slightly less granular |
| Documentation quality | Excellent — comprehensive guides, Flutter-specific docs | Good — improving but less extensive |
| Community size | Large — 10,000+ apps, active forums, Slack community | Growing — smaller but responsive support team |
| Third-party integrations | 30+ integrations including analytics, attribution, messaging | 15+ integrations — covers the essentials |
| Webhook support | Comprehensive — every lifecycle event, retry logic | Good — covers major events |
| Server-side validation | Full — App Store + Google Play | Full — App Store + Google Play |
Flutter SDK Comparison: Code Side by Side
Let me show you the same flow — initializing the SDK, fetching products, and making a purchase — in both RevenueCat and Adapty for Flutter.
RevenueCat Flutter Setup
// pubspec.yaml
dependencies:
purchases_flutter: ^7.0.0
// main.dart
import 'package:purchases_flutter/purchases_flutter.dart';
Future<void> main() async {
WidgetsFlutterBinding.ensureInitialized();
await Purchases.configure(
PurchasesConfiguration('your_revenuecat_api_key')
..appUserID = null // Anonymous until identified
);
runApp(const MyApp());
}RevenueCat: Fetching and Purchasing
class PaywallViewModel {
Future<Offerings?> loadOfferings() async {
try {
final offerings = await Purchases.getOfferings();
return offerings;
} catch (e) {
debugPrint('Failed to load offerings: $e');
return null;
}
}
Future<bool> purchase(Package package) async {
try {
final customerInfo = await Purchases.purchasePackage(package);
final isPro = customerInfo
.entitlements.all['pro']?.isActive ?? false;
return isPro;
} on PlatformException catch (e) {
final errorCode = PurchasesErrorHelper
.getErrorCode(e);
if (errorCode ==
PurchasesErrorCode.purchaseCancelledError) {
return false; // User cancelled
}
rethrow;
}
}
Future<bool> checkEntitlements() async {
final customerInfo = await Purchases.getCustomerInfo();
return customerInfo
.entitlements.all['pro']?.isActive ?? false;
}
Future<void> restorePurchases() async {
await Purchases.restorePurchases();
}
}Adapty Flutter Setup
// pubspec.yaml
dependencies:
adapty_flutter: ^3.0.0
// main.dart
import 'package:adapty_flutter/adapty_flutter.dart';
Future<void> main() async {
WidgetsFlutterBinding.ensureInitialized();
await Adapty().activate(
configuration: AdaptyConfiguration(
apiKey: 'your_adapty_api_key',
)..withLogLevel(AdaptyLogLevel.verbose),
);
runApp(const MyApp());
}Adapty: Fetching and Purchasing
class AdaptyPaywallViewModel {
Future<AdaptyPaywall?> loadPaywall() async {
try {
final paywall = await Adapty().getPaywall(
placementId: 'premium_upgrade',
);
return paywall;
} catch (e) {
debugPrint('Failed to load paywall: $e');
return null;
}
}
Future<List<AdaptyPaywallProduct>> loadProducts(
AdaptyPaywall paywall,
) async {
try {
return await Adapty().getPaywallProducts(
paywall: paywall,
);
} catch (e) {
debugPrint('Failed to load products: $e');
return [];
}
}
Future<bool> purchase(
AdaptyPaywallProduct product,
) async {
try {
final profile = await Adapty().makePurchase(
product: product,
);
return profile.accessLevels['premium']
?.isActive ?? false;
} on AdaptyError catch (e) {
if (e.code == AdaptyErrorCode.paymentCancelled) {
return false;
}
rethrow;
}
}
Future<bool> checkAccess() async {
final profile = await Adapty().getProfile();
return profile.accessLevels['premium']
?.isActive ?? false;
}
Future<void> restorePurchases() async {
await Adapty().restorePurchases();
}
}Both SDKs follow similar patterns. The core difference is in how products are organized. RevenueCat uses Offerings and Packages — you fetch an Offering that contains grouped packages. Adapty uses Paywalls and Placements — you fetch a paywall by placement ID, then get products attached to that paywall. Adapty's model is more opinionated about tying products to paywall contexts, which makes their no-code paywall builder possible.
Pricing at Scale: The Real Math
Let me model realistic costs at different revenue levels. This is where the decision gets interesting:
| Monthly Revenue (MTR) | RevenueCat Cost | Adapty Cost | Winner |
|---|---|---|---|
| $1,000 | $0 (free tier) | $0 (free tier) | Tie |
| $5,000 | $120/mo (Pro) | $0 (free tier) | Adapty |
| $15,000 | $225/mo (1.5%) | $199/mo (Pro) | Close — Adapty slightly cheaper |
| $50,000 | $750/mo (1.5%) | ~$500/mo (1%) | Adapty |
| $100,000 | $1,500/mo (1.5%) | ~$1,000/mo (1%) | Adapty |
Adapty wins on pure cost at almost every tier. The free tier is four times more generous ($10K vs $2.5K), and the revenue share at scale is lower (1% vs 1.5%). However, pricing is only one factor. RevenueCat's documentation, community support, and integration ecosystem often make up for the price difference — especially when you factor in the developer time saved by better docs and more StackOverflow answers.
The No-Code Paywall Builder: Adapty's Killer Feature
Adapty's standout differentiator is its visual paywall builder. You design paywalls in the Adapty dashboard using a drag-and-drop editor, and they render natively in your Flutter app without any code changes. You can:
- Create multiple paywall designs without writing Dart code
- A/B test different paywall layouts remotely
- Update paywall copy, images, and pricing presentation without app store updates
- Target different paywalls to different user segments based on placement
For teams that want to iterate rapidly on paywall design without going through the app review cycle, this is genuinely powerful. RevenueCat has introduced its own Paywalls feature with server-driven templates, but it is more limited in customization compared to Adapty's builder.
That said, if you want full control over your paywall UI — which I recommend for the best user experience — you will build custom paywalls in Dart regardless of which SDK you use. In that case, the no-code builder becomes less of a factor. See our paywall design guide for custom Flutter paywall templates.
When to Choose RevenueCat
RevenueCat is the right choice in these scenarios:
- You value documentation and community. RevenueCat's docs are among the best in the mobile SDK space. Their Flutter integration guide is thorough, and when you hit edge cases, you will find answers on their community forums, StackOverflow, and GitHub issues. With 10,000+ apps using RevenueCat, someone has likely solved your problem before.
- You need deep third-party integrations. RevenueCat connects to 30+ tools — analytics platforms, attribution providers, CRM systems, and messaging services. If you want subscription events flowing into Amplitude, Mixpanel, or AppsFlyer, RevenueCat's integration library is significantly larger.
- You are building your first subscription app. The learning curve with RevenueCat is gentler. Better docs, more tutorials, and a larger community mean fewer dead ends when you are figuring things out for the first time.
- You want the most battle-tested option. RevenueCat processes billions in subscription revenue annually. Their infrastructure has been stress-tested at scales that most indie apps will never reach. If reliability at scale is a concern, RevenueCat has the longer track record.
- You are already using The Flutter Kit. The Flutter Kit comes pre-integrated with RevenueCat — paywalls, entitlements, restore flow, and settings screen are all wired up. Switching to Adapty would require replacing the integration.
When to Choose Adapty
Adapty is the better choice in these scenarios:
- You want to iterate on paywalls without app updates. If paywall experimentation is central to your monetization strategy, Adapty's no-code builder is a genuine time saver. Create, test, and deploy new paywall designs from the dashboard.
- You are cost-sensitive at the $2.5K–$10K revenue range. If you are growing past $2,500/month in revenue but not yet at $10K, Adapty's free tier saves you $120/month compared to RevenueCat. That is $1,440/year — not trivial for an indie developer.
- You want to A/B test paywall designs remotely. While RevenueCat lets you A/B test pricing and offerings, Adapty lets you test entirely different paywall layouts and designs without touching code. This is powerful for optimizing conversion rates.
- You prioritize lower revenue share at scale. At 1% vs 1.5%, Adapty saves you $500/month at $100K MTR. Over a year, that is $6,000. If you are confident in your ability to handle a smaller ecosystem, the cost savings are real.
Integration Complexity: How Long Does Each Take?
Both SDKs are straightforward to integrate into a Flutter project, but there are differences in developer experience:
| Task | RevenueCat | Adapty |
|---|---|---|
| SDK installation | 15 min — add package, configure API key | 15 min — add package, configure API key |
| Dashboard product setup | 30 min — create app, map products, define offerings | 30 min — create app, map products, define placements |
| Basic paywall implementation | 2-3 hours — custom Dart UI + purchase logic | 1-2 hours — can use no-code builder or custom Dart |
| Entitlement gating | 30 min — check customerInfo.entitlements | 30 min — check profile.accessLevels |
| Testing (sandbox) | 1-2 hours — sandbox accounts, verify flows | 1-2 hours — sandbox accounts, verify flows |
| Total integration time | 4-6 hours | 3-5 hours |
Adapty's no-code paywall builder can save an hour or two on the initial paywall implementation. But if you are building a custom paywall UI anyway (which I recommend for the best conversion rates), the total integration time is roughly the same.
Why The Flutter Kit Chose RevenueCat
The Flutter Kit ships with RevenueCat pre-integrated. Here is why I made that choice:
- Documentation and developer experience. When you are building a boilerplate that thousands of developers will use, the quality of the underlying SDK's documentation matters enormously. RevenueCat's Flutter docs are the best in the space.
- Community support. When a Flutter Kit user hits an issue with subscriptions, I want them to find answers quickly. RevenueCat's larger community means more StackOverflow threads, more GitHub issues with solutions, and more tutorial content.
- Custom paywalls give better conversion. The Flutter Kit includes hand-crafted paywall templates that are designed to convert. I prefer building custom paywall UI in Dart over using a no-code builder — it gives you more control over the user experience.
- Integration depth. RevenueCat's webhook system and third-party integrations make it easier to connect subscription events to your Firebase backend, analytics, and marketing tools.
That said, The Flutter Kit's architecture uses a clean repository pattern. If you prefer Adapty, you can swap the subscription provider by replacing the RevenueCat repository implementation with an Adapty one. The paywall UI and entitlement gating logic remain the same.
Migration Considerations
If you start with one SDK and want to switch later, here is what is involved:
- Product configuration: Both SDKs require you to configure products in their dashboard. You will need to re-create your product mappings in the new provider.
- Code changes: Replace the SDK initialization, offering/paywall fetching, purchase calls, and entitlement checks. If you followed a repository pattern, this is a contained change.
- Existing subscribers: This is the hardest part. Active subscribers have their receipts stored in the old provider. Both RevenueCat and Adapty offer migration tools, but you will need to carefully handle the transition to avoid losing subscriber data.
- Analytics history: Historical analytics data does not transfer. You start fresh with the new provider.
The migration is doable but not trivial. It is better to choose the right provider upfront than to switch later.
My Recommendation
For most indie Flutter developers shipping their first subscription app in 2026:
Start with RevenueCat. It is free until $2,500/month, the Flutter SDK is mature and well-documented, and the community is large enough that you will never be stuck on a problem for long. The analytics dashboard alone is worth the integration effort. If you outgrow RevenueCat's free tier and find that Adapty's lower revenue share or no-code paywall builder would significantly benefit your business, you can migrate then — but most apps never need to.
If you are already generating $5K+/month in revenue and paywall experimentation is a core part of your growth strategy, consider Adapty. The no-code paywall builder and more generous free tier could save you meaningful time and money.
Either way, do not spend more than a day on this decision. Both are excellent products. The biggest mistake is deliberating when you should be shipping.
