- There's Woocommerce, which I've installed and tried doing basic setup, and it's too deeply bloated in the Wordpress ecosystem. My first impression from Prestashop was that it's going to be quite a similar PHP mess

- I don't want to get vendor locked-in with things like Shopify. They also don't seem to offer much design customizability (I'm a web dev and there's quite a unique design concept for the site from the artist)

- Searching GitHub for ecommerce, Solidus[1] looked quite promising, however, it also slightly overshoots the border of 'too complex' for me, and their docs on integrating a custom payments provider (a strict requirement - not US based) aren't really great

So my question is: are there any borderline-pet projects I've missed?

I've been doing web dev for over 2 years now, so I'm also thinking about building my own almost-serverless solution. Is that plausible in reasonable time (wouldn't want to give this more than 2 weeks), or are there too many holes to fall into even though the sensitive part of payments is handled by a simple integration?

One more bit of info, together with building this, their whole web is going to be transferred to a new CMS, likely the Netlify headless CMS (IMO a very cool concept - no backend, frontend uses GitHub http API to directly commit any saved changes). Therefore ideally I'd love to integrate the products inventory into this CMS, which saves data into markdown + front matter, and then can be built into HTML or any JSON to be fetched by frontend - that's why I said almost-serverless.
