Production checklist (when you’re ready)
This starter kit avoids vendor lock‑in. For real subscriptions:
- Use a billing provider (Paddle / Lemon Squeezy / Stripe).
- Validate licenses on your backend (Node/Go/Python) and issue JWT/session.
- Store user profiles in your DB (PostgreSQL, etc.).
- Optional: add email magic‑link login.
Want it fully hosted without Google products? A clean setup is: Cloudflare Pages + Supabase (auth & DB) + Paddle (billing).
