Can I vibe code Sticky.io?

KEEP — THE UI ISN'T THE MOAT
You pay Sticky.io primarily for processor independence, cascade payment routing, automated dunning, and PCI-compliant token vaulting across multiple merchant IDs (MIDs). If you only process payments through a single gateway like Stripe, building a subscription wrapper takes under a month using Stripe Billing. However, if your business depends on high-velocity rebilling, complex dunning rules, or routing transactions across multiple merchant accounts to maximize auth rates, an in-house build will require extensive engineering resources and strict PCI-DSS audit compliance.

Why this verdict
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.

The one-shot build prompt
Paste it into your agent of choice. Nothing else needed.
Build a full-stack Node.js and Next.js subscription management engine designed to interface with Stripe Billing. 1. DATA MODEL: Schema must include Customers (id, stripe_customer_id, email), Products (id, name, interval), Subscriptions (id, customer_id, product_id, stripe_subscription_id, status, current_period_end, cancel_at_period_end), Invoices (id, stripe_invoice_id, amount, status), and ActivityLogs. 2. CORE LOGIC: Implement endpoints for creating a checkout session, handling Stripe webhooks (customer.subscription.created, customer.subscription.updated, customer.subscription.deleted, invoice.payment_failed), skipping next delivery, pausing subscriptions, and swapping subscription products. 3. CUSTOMER PORTAL: Build a React dashboard allowing customers to view upcoming billing dates, change delivery frequency, update credit card info via Stripe Elements, and initiate cancellation flows with churn-reason tracking. 4. DUNNING & RETRIES: Create an admin page displaying failed payments, retry statuses, and sending automated transactional emails on invoice payment failure. 5. OUT OF SCOPE: Multi-MID cascade routing and custom payment token vaulting; rely strictly on Stripe's PCI Level 1 tokenized infrastructure.

FAQ
+Can I really replace Sticky.io with an AI-generated app?
NO — MULTI-GATEWAY ROUTING AND TOKEN VAULTING WILL CRUSH YOUR IN-HOUSE BILLING ENGINE. 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. An MVP takes roughly 2 weeks; matching the product properly is closer to 9-12 months, due to PCI compliance, payment token migrations, and multi-MID routing logic.
+How long does it take to rebuild Sticky.io?
A usable internal version: 2 weeks. A version you would sell or bet a business on: 9-12 months, due to PCI compliance, payment token migrations, and multi-MID routing logic, mostly spent on handling payment token migrations between payment processors without pci violations.
+What do you actually lose by leaving Sticky.io?
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
