I built this for my own SaaS (allgood.click) and decided to open-source it.
What's included:
- Stripe payments (one-time + subscriptions, mobile-optimized checkout)
- Automatic Zoho Invoice integration (PDF invoices sent on payment)
- 5 languages out of the box (EN, DE, ES, FR, PT)
- Cookie-free GDPR analytics with admin dashboard
Tech stack: Express.js, SQLite, vanilla JS (no build step)
Live demo: https://allgood.click
Happy to answer questions about the architecture or implementation details.
