SmolStack: Chrome Extension SaaS Starter Kit

Stop wasting weeks on Auth, Payments, and Databases. Just Ship your Chrome Extension.

SmolStack is a practical starter kit for shipping paid Chrome extensions faster. Includes email-based login/signup, secure payment flow, and database templates.

🛡️ Why SmolStack?

Most boilerplates rely on insecure client-side checks.
SmolStack uses server-side validation at the edge for better security.

• Order-Based License Validation
  Each activation is validated against real purchase records.
• Edge Verification
  Powered by Cloudflare Workers + D1 for fast, private checks.
• Reduced Piracy Surface
  No local-only flags or easily bypassed checks. Designed for casual piracy reduction, not enterprise-grade DRM.
• Cross-Browser User Sync
  PocketBase logic associates purchases with user metadata.
• Save ~20 hours of backend headaches.
  Ready-to-go architecture saves you weeks of coding.
