The ShipFast Alternative Built for Native iOS, Not the Web
ShipFast made shipping a Next.js SaaS fast. But the App Store doesn't run Next.js. The Swift Kit is the native SwiftUI boilerplate that gives iOS builders the same "ship in a weekend" feeling — auth, payments, AI, and a paywall — without a web stack pretending to be an app.
Last updated: June 2026
The best ShipFast alternative for iOS is The Swift Kit, a $99 one-time native SwiftUI boilerplate (unlimited commercial projects, lifetime updates, 14-day refund). Where ShipFast ships a Next.js web SaaS — Stripe, NextAuth, MongoDB — The Swift Kit ships an actual App Store app: Supabase auth, RevenueCat subscriptions, OpenAI/Claude/Apple Foundation Models AI, and a centralized SwiftUI design system. It's not a WebView wrapper or a cross-platform compromise; it's Swift code Xcode compiles to a real binary.
Why Developers Are Switching from ShipFast to The Swift Kit
It's native Swift, not a Next.js app squeezed onto a phone
ShipFast is a web boilerplate — its output runs in a browser or a PWA, and shipping it to the App Store means wrapping it. The Swift Kit is SwiftUI from the first line: it compiles to a native binary in Xcode, uses real iOS navigation, and behaves like an app Apple's reviewers expect to see, not a website in a frame.
The integrations are the iOS-native equivalents of ShipFast's stack
ShipFast pairs Stripe + NextAuth + MongoDB/Supabase for the web. The Swift Kit maps that to the platform: RevenueCat for App Store subscriptions and multi-tier entitlements (StoreKit done right), Supabase for auth — including Sign in with Apple, which Apple effectively requires — plus Postgres, storage, and Edge Functions.
AI proxied server-side the way an App Store app must do it
You can't ship OpenAI keys in an iOS binary — they're trivially extractable. The Swift Kit proxies OpenAI, Anthropic Claude, and Apple's on-device Foundation Models through Supabase Edge Functions with per-user rate limiting, so keys never leave your server. A web boilerplate's API-route pattern doesn't translate to a shippable iOS app on its own.
A real iOS paywall, not a Stripe checkout page
App Store apps that sell digital goods must use in-app purchase, not web checkout. The Swift Kit ships a RevenueCat-backed paywall and subscription flow designed for App Store Review — the thing a web-first boilerplate simply doesn't include because it never had to.
One-file retheme tuned for SwiftUI, not Tailwind
The Swift Kit's centralized 5-layer DesignSystem.swift rethemes the whole app from one place, with 5 native surface styles including Liquid Glass on iOS 26+. It's the SwiftUI counterpart to ShipFast's Tailwind components — but it renders with UIKit/SwiftUI materials, not CSS.
The Swift Kit vs ShipFast — Feature Comparison
| Feature | The Swift Kit | ShipFast |
|---|---|---|
| Target platform | Native iOS / SwiftUI (App Store binary) | Web / Next.js (browser, PWA) |
| Language & framework | Swift + SwiftUI | TypeScript + Next.js/React |
| Auth | Supabase + Sign in with Apple | NextAuth (Google/magic link) |
| Payments | RevenueCat in-app purchase + paywall | Stripe / LemonSqueezy web checkout |
| Database & backend | Supabase (Postgres, storage, Edge Functions) | MongoDB / Supabase (web) |
| AI integration | OpenAI, Claude, Apple Foundation Models (server-proxied) | Varies / OpenAI via API route |
| App Store-ready paywall | Yes — RevenueCat, built for App Review | No (web checkout) |
| Design system | DesignSystem.swift, 5 surface styles, Liquid Glass | Tailwind + DaisyUI components |
| Setup | Interactive ./setup.sh CLI | Clone + env config |
| Price | $99 one-time, lifetime updates | Publicly listed as a one-time fee (varies by tier) |
| License | Unlimited commercial projects | Per-tier (as of 2026) |
When ShipFast Is Still the Right Choice
We believe in honest recommendations. Here's when ShipFast might still be better for you:
- You're actually building a web SaaS or a marketing site — if your product lives in the browser, ShipFast's Next.js + Stripe stack is the right tool and The Swift Kit isn't meant for that job.
- You want SEO, server-rendered marketing pages, and web checkout as the core of the business; native iOS app + in-app purchase is a different distribution model entirely.
- Your team is a TypeScript/React shop with no Swift experience and no plan to learn it — staying on the stack you know will ship faster than adopting a native codebase.
“The Swift Kit is what ShipFast would be if Marc had built it for the App Store instead of the browser — native SwiftUI, RevenueCat, and Supabase wired up so you ship an iOS app, not a website in a wrapper.”

Frequently Asked Questions
Is The Swift Kit basically ShipFast for iOS?
In spirit, yes — same goal of shipping in a weekend, same batteries-included philosophy. The difference is the output: ShipFast produces a Next.js web app, while The Swift Kit produces a native SwiftUI app that Xcode compiles to an App Store binary. It's the iOS-native equivalent, not a port.
Can I just wrap a ShipFast site in a WebView and submit it to the App Store?
You can try, but Apple frequently rejects apps that are thin WebView wrappers of a website under guideline 4.2, and you'd lose native navigation, in-app purchase, and Sign in with Apple. The Swift Kit avoids that risk by being native from the start, with a RevenueCat paywall built for App Review.
How do payments differ between ShipFast and The Swift Kit?
ShipFast uses Stripe (or LemonSqueezy) web checkout, which is correct for a web SaaS. iOS apps selling digital goods must use in-app purchase, so The Swift Kit uses RevenueCat for subscriptions, multi-tier entitlements, and a native paywall — Stripe web checkout would get an App Store app rejected.
Does The Swift Kit handle AI the same way ShipFast does?
The intent is similar but the implementation must differ for iOS. ShipFast can call OpenAI from a server API route. The Swift Kit proxies OpenAI, Claude, and Apple's on-device Foundation Models through Supabase Edge Functions with per-user rate limiting, because you can never ship API keys inside an iOS binary.
I already own ShipFast. Do I still need The Swift Kit?
If you're shipping a web product, no — keep using ShipFast. If you want a native iOS app, ShipFast doesn't get you there, and The Swift Kit covers the iOS-specific pieces (StoreKit/RevenueCat, Sign in with Apple, native paywall, SwiftUI design system) that a web boilerplate can't.
What does The Swift Kit cost compared to ShipFast?
The Swift Kit is $99 one-time with unlimited commercial projects, lifetime updates, and a 14-day refund. ShipFast is publicly listed as a one-time fee that varies by tier; check their site for current pricing, since we don't quote competitor numbers we can't verify.
