StoreKit alternative — Tierux
StoreKit 2 gives you the building blocks, but you still need server-side verification, entitlement management, paywall UI, and cross-platform support. Tierux wraps all of that into one API — with AI-agent setup in minutes. Our App Store path is newer than our Google Play path, and the table below is honest about it.
| Capability | Tierux | StoreKit 2 (DIY) |
|---|---|---|
| Setup | AI-agent over MCP — Bundle ID + one prompt | Manual JWS parsing, server-side code, key management |
| Server-side verification | Store-verified on our servers, zero-trust client | Build and maintain your own verification server |
| Entitlement management | Built-in — queryable via REST API | Build your own entitlement state machine |
| Remote paywall config | Yes — change without app release | Hardcoded in your app |
| Cross-platform (Android) | Yes — unified entitlement model | Google Play Billing requires separate implementation |
| Pricing | Flat $39/mo up to 1,000 subscribers | Free — but engineering hours are your cost |
| Time to launch | Minutes via AI agent | Weeks to months of engineering |
| Subscription lifecycle sync | App Store Server Notifications wired — hardening in progress; Play RTDN fully handled | Build your own webhook handlers |
| Win-back / cancellation offers | Google Play — yes; App Store — not yet | Requires custom implementation |
| Maintenance burden | Zero — managed platform | Ongoing — store API changes, security patches |
StoreKit 2 is Apple's native framework and is free to use. The cost is in engineering time — building server-side verification, entitlement state management, paywall UI, and ongoing maintenance. Tierux provides these as a managed service.
