our call
Start with Circuly — 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
Skio
If you are a single Shopify merchant paying thousands in transaction fees, you can easily build a custom customer portal and cancellation flow on top of Shopify's native APIs using AI. Rebuilding the entire enterprise suite with zero-downtime migration, deep Klaviyo integrations, and payment recovery logic is significantly harder.

- Passwordless customer portal for skipping, swapping, or pausing subscriptions
- Build-a-box dynamic bundle selector UI
- Multi-step cancellation flow builder with deflection offers
- Basic subscription creation using Shopify Selling Plan API
- Automated email notifications via Klaviyo webhook integrations
what you lose
- Dedicated human migration engineering team to move subscription billing tokens securely without customer dropoff.
- Pre-built, maintained integrations with dozens of DTC stack tools (Klaviyo, Postscript, Gorgias, Triple Whale, Fondue).
- AI-driven payment retry timing optimization for recovering failed recurring credit card transactions.
- Bundled 1-way and 2-way SMS subscription management capabilities (SkioSMS).
- Turnkey no-code visual flow builders for customer retention and dynamic build-a-box bundles.
