Modern MoR for developers

Type
MoR

Polar.sh is a promising newcomer targeting the open-source funding and indie developer space. Its Stripe-like API with merchant-of-record services at 4% (vs Gumroad's 10%) is compelling, but the lack of a WordPress integration means it's not accessible to the WordPress audience without custom development.

Best for

Indie devs and OSS maintainers who want a Stripe-feel MoR.

Gumroad's 10% all-in rate appeals to solo creators who want a zero-setup experience and are willing to pay a premium for convenience and tax handling. For WordPress users who want to stay on their own domain, WP Smart Pay's Paddle integration offers a more professional approach at a much lower effective rate.

Best for

Solo creators selling ebooks, courses, or one-off digital downloads.
