Best affiliate tracking tools for a solo SaaS founder running their own program
Rewardful is the fastest to set up if you bill through Stripe, FirstPromoter covers more billing providers but locks you out of approving affiliates yourself, and PartnerStack adds a partner marketplace but comes with a real application review. The right one depends on how you'll actually find affiliates, not just how you'll pay them.

Read the verdictRewardful — best if you bill through Stripe and want to move fast
Rewardful is built specifically around Stripe: connect your account and it reads your real subscription and payment events directly, which is why solo founders consistently report being live within an hour. The tradeoff is the same as the strength — if you don't bill through Stripe, Rewardful isn't built for you at all, full stop. For a Stripe-billed SaaS with a small, personally-recruited affiliate list, it's hard to beat on setup speed.
FirstPromoter — best if you don't bill through Stripe
FirstPromoter covers a wider range of billing providers than Rewardful — Stripe, Paddle, Recurly, Braintree, and Chargebee are all supported, which matters if you're not on Stripe specifically. The real limitation worth knowing before you commit: FirstPromoter has no built-in marketplace for finding new affiliates, so you're bringing your own network either way. It's also worth noting that approving, declining, or editing individual affiliates and conversions isn't fully self-service — that goes through FirstPromoter's own team, which some founders find slower than they'd like.
PartnerStack — best once you want affiliates to find you
PartnerStack's real differentiator is its partner marketplace: publishers and content creators already browsing for B2B SaaS products to promote can discover your program there, on top of anyone you personally recruit. That inbound-discovery angle is genuinely valuable once you're past the "ask a few friends" stage — but it comes with a real, sometimes selective, application and review process on PartnerStack's side, not an instant self-serve signup. Worth knowing going in: this is the more enterprise-leaning option of the three, built with bigger partnership ecosystems in mind.
How we'd actually decide
- You bill through Stripe and want your first affiliate live today: Rewardful.
- You bill through Paddle, Recurly, Braintree, or Chargebee instead: FirstPromoter.
- You want affiliates to discover and apply to you, not just the people you recruit yourself: PartnerStack.
- You have fewer than 5 affiliates total and don't want to add another subscription yet: skip all three, track manually with unique Stripe coupon codes until it hurts.
