An Adapty Alternative for iOS Built for One-Developer Subscription Apps
Adapty is a powerful paywall and A/B-testing platform — but when you're a single developer shipping one subscription app, its dashboard-first model and revenue-based pricing can be more overhead than you need. The Swift Kit hands you a working RevenueCat paywall, entitlement gating, and a retheme-in-one-file design system for a flat $99, so the paywall lives in your codebase instead of behind someone else's dashboard.
Last updated: June 2026
As an Adapty alternative for iOS, The Swift Kit is a $99 one-time SwiftUI boilerplate that ships a complete RevenueCat paywall and entitlement layer instead of a separate paywall-management SaaS. Adapty is purpose-built for remote no-code paywall configuration and aggressive A/B testing; The Swift Kit is purpose-built for the solo developer who wants the paywall in their own repo with no per-revenue fees. If you run one subscription app and want to own the code, the flat price and RevenueCat-native setup fit; if you need server-driven paywall experiments across a large catalog, Adapty remains the stronger fit.
Why Developers Are Switching from Adapty to The Swift Kit
Flat $99 instead of revenue-scaled pricing
Adapty's paid tiers are publicly marketed around monthly tracked revenue thresholds, meaning your paywall tooling cost grows as your app grows. For a one-developer app, The Swift Kit is a single $99 purchase with lifetime updates and unlimited commercial projects — the paywall cost is fixed on day one and never indexes to your MRR.
The paywall lives in your repo, not a dashboard
Adapty is dashboard-first: paywalls are configured remotely and fetched at runtime, which is excellent for non-technical teams but adds a layer you don't control as a solo dev. The Swift Kit ships the paywall as SwiftUI you edit directly, backed by RevenueCat for entitlements, so there's no second console to learn and no remote config dependency in your purchase path.
RevenueCat-native, so you keep best-in-class StoreKit handling
The Swift Kit's paywall and multi-tier entitlements run on RevenueCat — receipt validation, restore, and cross-platform entitlement sync handled for you. You get a mature subscription backend without committing to a separate paywall platform on top of it.
It's a whole app, not just a paywall layer
Adapty solves paywalls. The Swift Kit solves the rest of the one-developer checklist too: Supabase auth (email + Sign in with Apple), 3 onboarding styles, TelemetryDeck analytics, push, and optional AI via OpenAI, Claude, and on-device Apple Foundation Models — all toggled by 6 feature flags so you ship the subscription app, not just the buy button.
One-file retheme keeps paywall and app visually consistent
Because the paywall is built on the same centralized 5-layer DesignSystem.swift as the rest of the kit, changing your brand color or surface style (Flat, Bordered, Elevated, Glass, or Liquid Glass on iOS 26+) restyles the paywall along with every other screen. Remote paywall builders style the paywall in isolation; here it inherits your app's design system automatically.
The Swift Kit vs Adapty — Feature Comparison
| Feature | The Swift Kit | Adapty |
|---|---|---|
| Pricing model | $99 one-time, flat | Revenue-scaled tiers (as of 2026) |
| Where the paywall lives | In your SwiftUI codebase | Remote dashboard, fetched at runtime |
| Subscription backend | RevenueCat (native) | Own SDK + StoreKit layer |
| No-code remote paywall builder | Yes (marketed core feature) | |
| Server-driven A/B paywall testing | Via RevenueCat / your own setup | Yes (marketed core feature) |
| Auth, onboarding, analytics, push included | ||
| AI modules (OpenAI, Claude, Apple Foundation) | ||
| Per-revenue fees as you scale | None | Varies by tier |
| Best fit | Solo dev, one subscription app | Teams running paywall experiments at scale |
When Adapty Is Still the Right Choice
We believe in honest recommendations. Here's when Adapty might still be better for you:
- You need a non-technical teammate (marketer, PM) to change paywall copy, layout, and pricing remotely without shipping an app update — Adapty's no-code remote builder is built exactly for that.
- You run a large catalog of subscription products and want continuous server-driven A/B and price testing as a core growth motion, which Adapty markets as a primary feature.
- You already operate multiple apps on Adapty and value its consolidated cross-app paywall analytics — re-implementing that as a solo dev with one app would be effort you don't need.
“The Swift Kit doesn't replace your subscription backend — it ships a RevenueCat-powered paywall and entitlement layer already wired into the app, so a one-developer subscription app is collecting payments on the same screen it onboards users.”

Frequently Asked Questions
Is The Swift Kit a true Adapty alternative for iOS?
For a one-developer subscription app, yes — it covers the job most solo devs hire Adapty for: a working paywall plus entitlement gating. It does this through a RevenueCat-native SwiftUI paywall in your own repo rather than a remote no-code dashboard, so it's an alternative in outcome (a paywall that converts) more than a feature-for-feature clone of Adapty's experimentation platform.
Does The Swift Kit charge fees based on my revenue like Adapty's tiers?
No. The Swift Kit is $99 one-time with lifetime updates and unlimited commercial projects. Adapty's paid plans are publicly marketed around tracked-revenue thresholds (as of 2026), so its cost can scale with your MRR; The Swift Kit's paywall cost is fixed regardless of how much you earn. Note RevenueCat itself has its own separate pricing.
Can I A/B test paywalls without Adapty?
Yes, though differently. Adapty markets server-driven paywall A/B testing as a core feature. With The Swift Kit you'd run experiments through RevenueCat's offerings/experiments or your own logic. If continuous, aggressive paywall testing is central to your growth, Adapty's purpose-built tooling is the stronger choice — that's an honest trade for owning the code.
Why does the paywall use RevenueCat instead of Adapty's SDK?
The Swift Kit standardizes on RevenueCat for receipt validation, restore, and multi-tier entitlements so the whole kit shares one mature subscription layer. As a solo dev you get a battle-tested StoreKit abstraction without adding a separate paywall platform on top. See our StoreKit 2 vs RevenueCat comparison if you're weighing the backend itself.
I'm not technical — should I still pick The Swift Kit over Adapty?
Probably not for the paywall specifically. If you can't or won't edit SwiftUI, Adapty's no-code remote paywall builder lets non-developers change copy, layout, and pricing without code. The Swift Kit assumes you're the developer editing the repo, which is exactly why it suits a one-person engineering team rather than a non-technical founder.
Does The Swift Kit only give me a paywall?
No — that's the main difference. Adapty focuses on paywalls; The Swift Kit ships the surrounding subscription app too: Supabase auth with Sign in with Apple, three onboarding styles, TelemetryDeck analytics, push, and optional AI features, all toggled by six feature flags. The RevenueCat paywall is one module among the pieces a solo dev needs to launch.
