our call
Start with Loop Subscriptions — highest vibe code, weakest moat.
Circuly
While coding a standard digital subscription cron job is straightforward, physical rentals require orchestrating deposit holds, asset inspection states, and return logistics. Replacing Circuly requires building a mini-ERP for serialized physical inventory alongside Stripe payment hooks.
you can rebuild
- Customer-facing rental tier selection widget
- Basic recurring billing triggers via Stripe Subscriptions API
- Customer portal for viewing active rentals and updating payment cards
- Automated email notifications for upcoming subscription renewals
- Basic pause and cancellation workflow UI
what you lose
- Pre-built physical product deposit capture and partial hold release engine
- Serialized asset tracking backend state machine (rented, returning, under inspection, refurbished)
- Turnkey Shopify product sync and real-time inventory locking for rental units
- Automated damage charge assessment workflows linked to pre-authorizations
- Out-of-the-box self-service customer return label generation integrations
real moats
- Operational state machine tuned specifically for physical hardware asset lifecycles
- Hardened handling of payment edge-cases like recurring deposit holds and PSD2/SCA compliance
- High switching costs driven by active recurring payment agreements tied to serial numbers
open source escape hatches
- Medusa JS MIT
- Kill Bill Apache-2.0
- PostgreSQL + Express + Stripe Engine MIT
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.

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.
real moats
- Turnkey white-glove data migration pipelines from legacy systems like Recharge or Skio without subscription downtime or token loss.
- Deep ecosystem integrations (Klaviyo, Gorgias, Smile.io, Attentive) built over years with dedicated webhooks and state syncing.
