Best StoreKit 2 Alternative — Why RevenueCat Is the Smart Choice for iOS Subscriptions
StoreKit 2 is powerful but requires significant server-side infrastructure. RevenueCat wraps StoreKit 2 with everything else you need — so you can focus on your app instead of subscription plumbing.
Last updated: June 2026
The best alternative to managing StoreKit 2 subscriptions manually is RevenueCat. It provides server-side receipt validation, subscription analytics, A/B testing, and handles edge cases like billing retry and grace periods that would take 100+ hours to build yourself. RevenueCat is free up to $2,500/month in revenue, and The Swift Kit includes it pre-integrated.
Why Developers Are Switching from StoreKit 2 (Native) to RevenueCat
Server-Side Validation Built In
StoreKit 2 validates on-device. RevenueCat validates server-side — which is required for most backends, refund handling, and fraud prevention. Building your own server-side validation takes weeks.
Subscription Analytics Dashboard
MRR, churn rate, trial conversion, LTV — all visible in the RevenueCat dashboard. StoreKit 2 gives you raw transaction data. Building an analytics dashboard from that takes significant effort.
A/B Testing Paywalls
RevenueCat Paywalls lets you A/B test pricing, layouts, and copy without App Store resubmission. StoreKit 2 has no built-in A/B testing — you would need to build this from scratch.
Edge Case Handling
Family sharing, grace periods, billing retry, offer codes, promotional offers — RevenueCat handles all of these automatically. With StoreKit 2 alone, each edge case is days of development and testing.
Cross-Platform Support
If you ever expand to Android or web, RevenueCat provides a unified API. StoreKit 2 is iOS-only. Having one subscription system across platforms saves massive engineering time.
Free for Indie Developers
Free up to $2,500/month in tracked revenue. Most indie apps do not hit this threshold for months after launch. You get enterprise-grade subscription infrastructure at zero cost.

When StoreKit 2 (Native) Is Still the Right Choice
We believe in honest recommendations. Here's when StoreKit 2 (Native) might still be better for you:
- You want zero external dependencies and are willing to build server-side validation, analytics, and edge case handling yourself
- Your app has very simple IAP (e.g., one-time purchase only, no subscriptions) where RevenueCat's infrastructure is overkill
- You are building a learning project and want to understand StoreKit 2 internals deeply
- Your revenue exceeds $100K/month and RevenueCat's pricing tier becomes a meaningful cost factor
- You already have custom server-side subscription infrastructure built and maintained by your team
“The Swift Kit includes RevenueCat fully pre-integrated on top of StoreKit 2. Paste your API key in Secrets.swift and paywall templates, subscription management, trial logic, restore behavior, and entitlement checking all work immediately. Leave the key empty and the app falls back to demo offerings — it never crashes from a missing key.”

Other StoreKit 2 Alternatives (and How They Compare)
RevenueCat is the default pick, but a few other subscription platforms are worth knowing before you commit:
- Adapty — the closest RevenueCat competitor, with strong paywall A/B testing and analytics and a generous free tier. A good fit if paywall experimentation is your top priority.
- Glassfy — lightweight subscription infrastructure focused on simplicity, with fewer analytics features than RevenueCat.
- Apphud — subscription management plus marketing and attribution tooling; popular with growth-focused teams.
- Paddle — a Merchant of Record that handles global tax and VAT for you, but it is web-billing oriented rather than native StoreKit-first.
How to Migrate From StoreKit 2 to RevenueCat
Migration is straightforward because RevenueCat sits on top of StoreKit 2 rather than replacing it. Add the SDK, map your existing App Store product identifiers to RevenueCat entitlements, set your App Store shared secret so server-side validation works, and replace direct StoreKit calls with RevenueCat’s Purchases API. Existing subscribers are recognized automatically on first launch. In The Swift Kit this is already wired — paste your API key and the paywall, restore, and entitlement logic work immediately.
Frequently Asked Questions
Is RevenueCat better than StoreKit 2 for iOS subscriptions?
For most indie iOS developers, yes. RevenueCat is the best StoreKit 2 alternative because it adds server-side receipt validation, a subscription analytics dashboard, paywall A/B testing, and automatic handling of edge cases (family sharing, grace periods, billing retry) on top of StoreKit 2 — features you would otherwise spend 100+ hours building. Native StoreKit 2 is the better choice only if you want zero dependencies and are happy to build that infrastructure yourself.
Do I still need StoreKit 2 if I use RevenueCat?
You do not call it directly, but RevenueCat uses StoreKit 2 under the hood on iOS 15+. So you get native StoreKit 2 performance and behavior, with RevenueCat's server-side infrastructure and dashboard layered on top. You write against RevenueCat's Purchases API instead of StoreKit directly.
Is RevenueCat free?
RevenueCat is free up to $2,500/month in tracked revenue (about $30K/year). After that, pricing starts at $99/month. For most indie apps, the free tier covers the entire early growth phase.
When should I use native StoreKit 2 instead of RevenueCat?
Use native StoreKit 2 when you want zero external dependencies and are willing to build server-side validation and analytics yourself, when your purchases are very simple (a single one-time purchase, no subscriptions), when you are learning StoreKit internals deliberately, or when your revenue is high enough that RevenueCat's percentage becomes a meaningful line item and you already have a team to maintain billing infrastructure.
What does RevenueCat do that StoreKit 2 does not?
Server-side receipt validation, a subscription analytics dashboard (MRR, churn, trial conversion, LTV), A/B testing for paywalls, cross-platform support (Android + web), automated billing retry, grace period handling, offer code management, and webhooks for backend sync. Building all of this with StoreKit 2 alone takes 100+ hours.
Does RevenueCat lock me in to their SDK?
There is some coupling — you write against RevenueCat's API rather than StoreKit directly — but your products, prices, and subscriptions live in App Store Connect, which you own. Because RevenueCat sits on StoreKit 2, you can migrate back to native StoreKit if you ever need to; your subscribers and store configuration are not held hostage.
How long does it take to migrate from StoreKit 2 to RevenueCat?
For a typical indie app, a few hours to a day. You add the SDK, map your existing product identifiers to RevenueCat entitlements, set your App Store shared secret for server-side validation, and swap direct StoreKit calls for the Purchases API. Existing subscribers are recognized automatically on first launch. The Swift Kit ships this already wired.
What are the best RevenueCat and StoreKit 2 alternatives?
The main alternatives are Adapty (strong paywall A/B testing and analytics), Glassfy (lightweight, simple), Apphud (subscription management plus attribution), and Paddle (a Merchant of Record that handles global tax, but web-billing oriented). RevenueCat remains the most popular all-round choice for native iOS subscriptions.
