Start with Subbly — highest vibe code, weakest moat.
Loop Subscriptions
You can easily build a custom Shopify subscription app that eliminates Loop's 1% transaction fee using native Shopify APIs in a few weeks. However, replacing Loop's deep app store integration ecosystem, white-glove migration scripts, and battle-tested dunning algorithms requires significant ongoing development.
you can rebuild
- Basic recurring product subscriptions (Shopify Selling Plans integration)
- Self-serve customer portal for skips, pauses, and product swaps
- Basic cancellation save flows with pause/discount offers
- Automated payment recovery (dunning retries)
- Shopify Theme App Extensions for selling plan widgets on product pages
what you lose
- Managed migration support to transfer active vaulted payment tokens from older platforms.
- Out-of-the-box native integrations with marketing and support tools (Klaviyo, Gorgias, Attentive).
- Dedicated Customer Success Manager and shared Slack support channel.
- Gamified retention features like loyalty streak tracking and mystery rewards.
- Built-in A/B testing infrastructure for cancellation flows.
