WooCommerce hosted on a dedicated platform such as Cloudways. It's incredibly extensible, and has a thriving third-party addon ecosystem.

NopCommerce has spent the last 5-10 years pouring most of its development resources into keeping up with the ever-changing .net ecosystem. You can imagine what a code base is like when the framework it's built upon is being swapped out every one to 2 years.

Its third-party ecosystem is sorely lacking.

The schema it uses for product attribute combinations is brittle and poorly designed, making fine-grained discounting and reporting almost impossible, among other things.

Redirection style payment methods will leave you with an empty shopping cart if you return to the site before completing payment (eg, to verify your cart's contents).

I've reported easily reproducible bugs and the devs simply refuse to fix them (such as double discounting for associated products), seemingly due to them not taking the issue seriously or failing to understand the issue.

tldr - NopCommerce sucks.

Depending on your needs, NextJS Commerce (Vercel) storefront + Vendure backend is a full-stack JavaScript fully-OSS option for this. It's basically ready-to-go if you have a B2C/Retail "sneaker store" type use case selling a handful of products, they have a blessed integration + demo for using Vendure but you could swap out for another backend if you liked.

Thank you for sharing . Packed Coffee (in 250g, 500g and 1kg) is the product I’m trying to build for . Is versed the best choice for this in your view?

If you have 3 products and <100 active orders (e.g., need to be fulfilled / tracked at any given time) then you're in a nice spot for Vendure as an eCommerce backend

WooCommerce, because everyone else uses it.

Thanks, Do I need a WordPress site prior to using WooCommerce?

Yes, WooCommerce is a plugin for WordPress.

Only if you see no other way than to use Wordpress as a base.

I am not aware of any other OSS ecommerce software as well supported as Woocommerce - and you never want to depend on something with not-good support with your business.

Have you looked into Medusa? I haven't used it but it's highly rated and has good reviews.

Shopify

Pro - Slick UI - Solid backend to manage products - Good plugin support with other e-commerce giant like Amazon, eBay - Good community support - Flexible store customization with good range of theme - Easy to manage even for even non-IT person(Taking about backend process like product listing, shipment generation etc...)

That's NOT an open source e-commerce platform!

That’s what I thought too

nopCommerce - Open Source but with commercial support, good community, paid and free plugins in the marketplace. Lots of options.

Notepad, GitHub Pages, PayPal

I didn’t know GitHub pages can do e-commerce!
