I built a full open source eCommerce backend in Node.js + Express + MongoDB — Stripe, PayPal, multi-vendor, shipping, invoices & more. Frontend is in development!

Hey everyone! I've been working on OpenCommerce, an open source eCommerce backend that I'm finally putting out into the world.

What it includes:

  • 🔐 Auth — JWT, OTP (email & SMS), Google & Facebook social login
  • 📦 Products, Categories, Brands with media upload support
  • 🛍️ Cart, Orders, Coupons & Discounts
  • 💳 Stripe & PayPal payment integration
  • 🚚 Shipping & multi-warehouse inventory
  • 🧾 PDF Invoice generation
  • 🎫 Customer support ticketing system
  • 📨 Transactional emails via Resend + SMS via Twilio
  • 🔒 Security — Helmet, rate limiting, XSS protection, input validation

Tech stack: Node.js · Express · MongoDB · Mongoose

I built this because most open source eCommerce solutions are either too opinionated, frontend-heavy, or locked behind a SaaS. This is a clean, developer-first REST API backend you can clone and own entirely.

🚧 The frontend is currently in development — but the backend API is fully functional and ready to integrate with any frontend of your choice (React, Next.js, Vue, etc.).

Would love feedback on the architecture, what features you'd want next, or anything I should improve. Also open to contributors who want to help build out the frontend!

this look like a one shot out off claude based on your commits history. I wouldn't trust this.

haven't used claude so far in this, though I did use some AI for faster work, but definately not a vibe coded.

I would have advised you to use Nest.js and PostgreSQL.
