But sellfy started at under 5% fees and selly was originally free. These are the pricing models they moved to with the hopes of growing beyond the percent commissions which honestly isn't that great for the general “indie” market.

They do both have multiple clones that have popped up and which you could eventually probably find for free.

Sellfy sort of went with artists if I remember correctly. Another one focused on films. Another on ebooks. Others stay general to digital products but be aware you're also going to have to combat fraud.

Rocketr continues to process orders but development did for the most part stall after not being able to move toward payment processing more generally (costly).
