Adapty is a platform. Steplark is a sharp tool.
Adapty bundles a subscription backend, predictive analytics, and a no-code builder into one heavy platform. Steplark is the sharp alternative: a fast, code-native editor where AI writes the screen, and onboarding and paywalls that render the instant the app opens — one configure call, nothing to adopt.
You wanted onboarding. Adapty sells you a platform.
A full revenue platform is a commitment: a backend to adopt, a heavy SDK, and a no-code builder to wrestle. Most of it is weight if the job in front of you is the onboarding and paywall funnel.
A platform to adopt, not a tool to drop in
Adapty is a broad, all-in-one revenue platform: a backend, a heavy SDK, and a dashboard built to do everything. That's a commitment. Steplark is one configure call that presents your flow on launch — nothing to adopt.
A builder you fight
Adapty's editor is a no-code visual builder — drag boxes, nudge spacing, wrestle the canvas. Steplark's editor is code-native: describe a change and the AI writes the screen, shows you a reviewable diff, and waits for Apply.
Onboarding that doesn't render at launch
Steplark pre-warms onboarding so it's on screen the instant the app opens — native shimmer, no spinner, no flash, no network on the critical path. The first screen is the highest-intent moment. Own it.
Steplark vs Adapty, line by line.
Both build onboarding and paywalls. The rows below are honest about where Adapty's platform leads and where Steplark's focus wins.
| Steplark | Adapty | |
|---|---|---|
| Onboarding flow builder | Multi-screen, A/B tested, renders at launch | Onboarding builder |
| Paywall builder | Remote, templated, A/B tested | Remote paywall builder |
| Editor | Code-native canvas, AI writes the screen, reviewable diffs | No-code visual builder |
| Owns the first screen (app launch) | Pre-warmed, renders the instant the app opens | Onboarding/paywall on trigger |
| Per-screen funnel analytics | Views, drop-off, dwell, conversion, revenue | Onboarding and revenue analytics |
| Subscription backend + predictive LTV | StoreKit 2 in-app, no backend to adopt | Full backend with predictive analytics |
| Cross-platform | iOS today (Android, web later) | iOS, Android, and more |
| Sticky A/B testing | Across onboarding and paywall, sticky per device | Paywall and onboarding A/B |
| Setup | One configure call, presents on launch | Platform + backend onboarding |
| SDK footprint | Zero dependencies | Broader platform SDK |
| Pricing | Flat, per monthly user. Never a cut of revenue | A percentage of tracked revenue |
The focused way to ship the funnel.
Everything that turns an install into a paying user — and nothing you have to adopt a platform to use.
An editor that keeps up
Describe a change and the AI writes the screen in real code, with a reviewable diff and nothing shipping until you click Apply. A fast, code-native canvas, not a drag-and-drop builder you fight.
Renders the instant the app opens
Pre-warmed and native-shimmered, your onboarding is the first thing on screen with no network latency on the critical path. You own t=0.
One funnel, one set of analytics
Per-screen views, drop-off, dwell, completion, and paywall revenue in one place, so the leak is a row in a table, not a cross-tool investigation.
A/B test every step
Sticky, per-device A/B tests across onboarding and paywall. Test, read the result, and ship the winner over the air.
One configure call
Add Steplark, call configure with your API key, and the flow shows itself on launch. Zero dependencies, nothing else to wire.
Flat pricing, no revenue share
Priced on the users who see your funnel, never a percentage of your revenue. Free up to 2,500 monthly users.
When each one is the right call.
Honest answer: it depends on whether you want a platform or a tool.

Steplark vs Adapty, answered.
What's the difference between Steplark and Adapty?
Adapty is an all-in-one revenue platform: a subscription backend, predictive analytics, paywalls, and an onboarding builder, across platforms. Steplark is a focused iOS tool for onboarding and paywalls that render at launch, integrated in one configure call with no backend to adopt.
Is Steplark a lighter Adapty alternative?
Yes. If Adapty feels like more platform than you need, Steplark covers the part most teams actually iterate on — the onboarding and paywall funnel — without the subscription backend, predictive analytics, or cross-platform scope. One SDK, one configure call.
Does Adapty do onboarding like Steplark?
Adapty has an onboarding builder, so both build onboarding. The difference is focus and behavior: Steplark is iOS-native, pre-warms onboarding so it renders the instant the app opens, and ships as a single dependency-free configure call.
Does Steplark have a subscription backend or predictive analytics?
No. Steplark uses StoreKit 2 directly and focuses on building, A/B testing, and measuring the onboarding-to-paywall funnel. If you specifically need a subscription backend or predictive LTV across platforms, Adapty is built for that.
How much does Steplark cost compared to Adapty?
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 price by reach. Adapty's paid plans are a percentage of tracked revenue.
Skip the platform. Ship the funnel.
