Where it fits

Editorial opinion

PromoteKit is a credible way to test a Stripe-based affiliate program for a few referrals before paying. Once the free cap is reached, compare Pro's revenue allowance, optional payout charges and Stripe dependence with alternatives offering other billing connectors.

Consider it for

Stripe-based solo founders and small SaaS teams testing a first affiliate program, particularly those wanting coupon tracking and a real but capped free tier.

Check before choosing

Merchants who use Paddle instead of Stripe, need more than three referrals without paying, or exceed Pro's $10,000 monthly affiliate-attributed revenue allowance.
