our call
Start with Subkit — highest vibe code, weakest moat.
Appstle
You can build a functional subscription widget and recurring charge generator using Shopify's Selling Plan API in under two weeks. However, replicating Appstle's full suite—including passwordless customer portals, complex build-a-box mechanics, product swap rules, and edge-case dunning retry pipelines—requires months of engineering and constant API upkeep.
you can rebuild
- Recurring billing schedules (Pay-as-you-go and Prepaid).
- Self-service customer portal for pausing, skipping, and swapping subscription items.
- Basic subscription widget embedded on product detail pages (PDP).
- Automated dunning retries and basic email notifications for failed payments.
- Basic subscription analytics (Active Subscribers, MRR, Churn Rate).
what you lose
- 24/7/365 live customer support for handling merchant theme breaks and sub setup.
- Automated, zero-downtime subscription data migrations from competitors like Recharge or Bold.
- Turnkey native integrations with Klaviyo, Gorgias, Zapier, PageFly, and Shopify Flow.
- Built-in passwordless customer portal authentication out of the box.
- Pre-built retention tools like discount offers during subscription cancellation flows.
