Open registration, data isolated per user
Free quota for your users, enforced server-side
Creem payments — one-time purchase unlocks Pro
Admins manually mark paid / revoke

List price US$49.9

Already done for you

Sign-up, sign-in, and sign-out are wired up; pages that require login can't be opened without one.
Every data type ships with list, create, and edit pages plus matching CRUD APIs.
Required fields and dropdown options are re-validated on the server.
Each user only sees their own data — tweaking the URL won't open someone else's.
Usage caps for unpaid users are enforced on the server, not bypassable from the browser.
The public site and the admin share one codebase — change it once, both update.
Deployment steps, troubleshooting, and ready-made prompts for Codex / Claude Code are in the docs.

What's not included

WeChat/Alipay direct (Creem only)
Team seats & collaboration
Usage-based billing
