The only thing that comes to mind right now is :

the **Magic Webstore** :

https://magicwebstore.xyz/onboard.html

"With Magic Webstore, your entire store is contained in your magic string, like a genie in a lamp. You just need to save that one string (back it up and store it safely) and you can do everything you need: add products to your store, manage your inventory, track your income, and keep your money safe."

For lightning : "It connects to legend.lnbits.com by default for lightning payments. You can already connect it to your own node, instructions are available on the admin page."
