Digistore24

Started in 2012, Digistore24 combines an affiliate network with a digital product marketplace and integrated checkout system. Vendors can create multi-step upsell sequences and automate affiliate commission payouts, making it popular in the digital course space where creator-to-affiliate relationships matter.

Best for course creators already using affiliate models who want one unified platform for sales processing and partner management. Unlike pure checkout tools, Digistore24 handles affiliate recruitment and tracking natively, trading some simplicity for built-in monetization reach.
