RevenueCat counts the revenue. Steplark builds the funnel that makes it.
RevenueCat is a subscription backend with a paywall on top, and it's good at that. But it doesn't build or optimize the onboarding that drives the purchases. Steplark builds onboarding and paywalls as one flow, A/B tests every screen, and shows you exactly where the funnel leaks.
RevenueCat tracks your revenue. It doesn't grow it.
A subscription backend tells you what happened. The onboarding and paywall that decide whether it happens at all are a different job — and not one RevenueCat does.
It's a backend, not a funnel
RevenueCat validates receipts, tracks entitlements, and reports revenue. It does that well. But it doesn't build the onboarding that drives the purchases it's counting.
No onboarding flow builder
RevenueCat ships paywalls and subscription infrastructure. The multi-screen onboarding that leads into the paywall is still yours to hand-code and re-ship through App Review.
It reports revenue, not drop-off
RevenueCat's analytics tell you what your subscriptions did. They can't tell you which onboarding screen lost the user before the paywall ever loaded.
Steplark vs RevenueCat, line by line.
RevenueCat owns the subscription backend. Steplark owns the funnel that fills it. The rows below are honest about both.
| Steplark | RevenueCat | |
|---|---|---|
| Onboarding flow builder | Multi-screen, built on a canvas, A/B tested | Paywalls and subscriptions, not onboarding flows |
| Paywall builder | Remote, templated, A/B tested | Remote paywall builder |
| Onboarding + paywall as one funnel | One connected flow, edge to edge | No onboarding layer |
| Per-screen onboarding analytics | Views, drop-off, dwell, conversion, revenue | Subscription & paywall analytics |
| Owns the first screen (app launch) | Onboarding renders the instant the app opens | Paywalls on trigger |
| Subscription backend (receipts, entitlements, webhooks) | Uses StoreKit 2 directly in-app | Full server-side subscription backend |
| Cross-platform | iOS today (Android, web later) | iOS, Android, and more |
| Sticky A/B testing | Across onboarding and paywall, sticky per device | Paywall and price experiments |
| Remote updates, no app release | Yes | Yes |
| SDK footprint | One configure call, zero dependencies | Subscription SDK |
| Pricing | Flat, per monthly user. Never a cut of revenue | A percentage of tracked revenue |
The funnel RevenueCat doesn't build.
Everything that turns an install into a subscriber, built and measured in one place.
Build the onboarding, not just the paywall
Design the whole flow from first launch to purchase on a canvas, and ship it over the air. The screens that create the subscription, not just the screen that closes it.
See where the funnel leaks
Per-screen views, advances, backs, dwell time, completion, and paywall conversion in one funnel. Find the screen that's costing you, then fix it.
A/B test the whole flow
Sticky, per-device A/B tests across onboarding and paywall. Test the quiz, the value prop, the price, the order — and ship the winner without a release.
Render at launch
Onboarding is pre-warmed and shows the instant the app opens, so you own the highest-intent moment instead of waiting for a trigger later in the session.
Drop in with one call
Add Steplark, call configure with your API key, and the flow presents itself. No backend to stand up, no entitlement plumbing to wire.
Flat pricing, no revenue share
You're priced on the people who see your funnel, never a percentage of what you earn. Free up to 2,500 monthly users.
When each one is the right call.
They're not the same layer of the stack — so the honest answer is about what you're solving.
Reach for RevenueCat when
You need a subscription backend: server-side receipt validation, cross-platform entitlement state, webhooks, and revenue reporting across iOS and Android.
Reach for Steplark when
The thing holding back revenue is the onboarding and paywall funnel itself — and you want to build it, A/B test it, and see where it leaks, on iOS, over the air. Start from a template.
Steplark vs RevenueCat, answered.
Is there a RevenueCat alternative with onboarding?
Yes. Steplark builds iOS onboarding flows and paywalls together and serves them over the air. RevenueCat focuses on subscription infrastructure and paywalls; Steplark focuses on building and optimizing the onboarding-to-paywall funnel.
What's the difference between Steplark and RevenueCat?
RevenueCat is a subscription backend — receipt validation, entitlements, webhooks, and revenue reporting — with a paywall builder on top. Steplark is the funnel layer: it builds, A/B tests, and measures the onboarding and paywall that drive those subscriptions. Different layers of the same stack.
Can Steplark replace RevenueCat?
It depends what you use RevenueCat for. Steplark handles in-app purchases through StoreKit 2 and owns the onboarding and paywall funnel. If you rely on RevenueCat for server-side receipt validation, cross-platform entitlement state, and subscription webhooks at scale, that's a backend Steplark isn't trying to be. If your priority is iOS onboarding and paywall conversion, Steplark is the focused alternative.
Does RevenueCat build onboarding flows?
No. RevenueCat builds paywalls and manages subscriptions. A multi-screen onboarding flow is something you'd build yourself in native code, or with Steplark.
How much does Steplark cost compared to RevenueCat?
Steplark is priced on the monthly users who see your funnel and never takes a percentage of your revenue — free up to 2,500 monthly users, then a flat monthly price by reach. RevenueCat's paid plan is a percentage of the revenue you track.
