our call
Start with Smartrr — highest vibe code, weakest moat.
Smartrr
While creating a basic recurring order generator is easy, building a production-grade subscription engine requires orchestrating Shopify's Subscription Contracts API, tokenized payment retries, and dunning cycles. A DIY solution risks silent billing failures, customer churn, and payment gateway compliance gaps.
you can rebuild
- Custom customer account portal for skipping or pausing renewals
- Product swap UI and bundle builder widgets
- Basic dunning email trigger notifications
- Order frequency schedule selector on product pages
- Custom discount codes applied to recurring cycles
what you lose
- Turnkey migration tools for active payment tokens
- Pre-built integrations with Klaviyo, Gorgias, and Attentive subscription events
- Turnkey dunning/retries optimized for failed credit card tokens
- Built-in churn analytics and cancellation survey branching
- Ongoing maintenance against Shopify Subscription API breaking changes
real moats
- Substantial switching costs due to subscriber payment token migration risks
- Pre-built webhooks and event pipelines into key ecommerce marketing stacks
- Battle-tested automated dunning workflows and credit card retry logic

- Kill Bill Apache-2.0
- Lago AGPL-3.0
- Medusa Core MIT
Stay AI
You can replace Stay AI's core subscription portal, skip/swap logic, and basic cancellation flows with an AI-generated app in a couple of weeks. However, matching their automated reinforcement-learning save flows, churn prediction models, and zero-touch migration services requires serious custom ML data engineering and ongoing operations.

- Cancellation survey flows and retention save offers
- Bundles and build-your-own box UI
- Gamified digital punch cards and loyalty milestones

what you lose
- Proprietary reinforcement-learning models for dynamic retention save offers
- Turnkey white-glove migration team to transfer raw contract data from legacy platforms
- Dedicated human subscription growth strategist
- Pre-configured multi-channel integrations (Attentive, Postscript, Gorgias, Rebuy)
- Benchmarked retention analytics compared against industry-wide DTC cohorts
