our call
Start with Subflow — highest vibe code, weakest moat.
Sticky.io
Basic recurring billing logic using Stripe is easy to build with AI, but Sticky.io handles multi-MID processing, cascade routing, card account updates, and PCI vaulting. Migrating vaulted payment tokens away from a custom setup when gateways decline transactions is a compliance nightmare.
you can rebuild
- Basic subscriber portal for pause, skip, and swap
- Subscription catalog and discount code management
- Recurring order schedule generation
- Basic email notifications for upcoming rebills
- Standard churn reporting and dashboard metrics
what you lose
- Multi-MID and gateway cascade routing engine
- PCI Level 1 compliant token vaulting outside of standard gateways
- Visa/Mastercard Account Updater (VAU/ABU) integration for expired cards
- Sophisticated decline recycling and smart dunning sequences
- Built-in chargeback protection software integrations
real moats
- PCI-DSS compliant payment token vault across multiple gateways
- Pre-built integrations with merchant processing gateways and fraud tools
- Historical transaction routing data for decline optimization

Subflow
Subflow provides a structured subscription layer, billing schedule engine, and customer portal. Stripe Billing API handles the underlying payment collection, card vaulting, and recurring logic natively. If you have custom web applications, building this around Stripe APIs is quick, but managing dunning edge cases and payment retries requires effort.
you can rebuild
- Self-service customer subscription portal (pause, skip, swap, cancel)
- Recurring billing cycle logic and automated renewal triggers
- Transactional billing emails for successful payments and failures
- Subscription plan setup (frequency, discount tiers, trial periods)
- Basic MRR, active subscriber, and churn reporting dashboard
what you lose
- Turnkey PCI-compliant hosted subscription checkout pages
- Pre-integrated dunning management algorithms optimized for card retries
- Native plug-and-play integrations with popular email service providers (Klaviyo)
- Built-in support for physical box order generation workflows
- Zero-code subscription setup for non-technical team members
real moats
- Payment gateway credit card token lock-in and migration risk
- Deep ecosystem integrations with fulfillment, tax, and marketing platforms
- Involuntary churn reduction algorithms refined across millions of transactions

Which is easier to rebuild with AI, Sticky.io or Subflow?
Subflow. It scores 6/10 on vibe code with a moat of 3/10, so an AI-assisted MVP takes about 1 week and a full replacement about 3-6 months, due to dunning workflows, complex schedule management, and payment token migrations.
Which one costs less, Sticky.io or Subflow?
