What is the most popular affiliate software for SaaS?

Counted by the programs that use it, PartnerStack: it runs 104 of the 352 SaaS and software affiliate programs in our directory whose platform we could read (29.5%), ahead of FirstPromoter (63, 17.9%) and Impact.com (59, 16.8%). Among tools a company rents to run its own program (rather than a network), FirstPromoter leads with 63.

Do most SaaS companies run their affiliate program in-house?

55% of the 795 programs we counted (434) sign affiliates up on the brand's own website, where the page does not show which tracking software runs it. Many of those still use one of the platforms in the table behind their own domain, so read each platform's share as a floor, not a ceiling.

Do SaaS programs use affiliate software or affiliate networks?

39% of the programs with a known platform run on affiliate software, which the company rents to run its own program (FirstPromoter, Rewardful, Tapfiliate and others), and 61% on a network or partner marketplace led by PartnerStack, where one affiliate account reaches many brands.

Which affiliate platforms have the most recurring-commission programs?

Among platforms running at least 10 of the programs we counted: Reditus (90% of its 10 programs pay recurring), FirstPromoter (87% of its 63 programs pay recurring), Rewardful (82% of its 33 programs pay recurring).

How was this counted?

We counted the 795 programs in SaaS, marketing, hosting and security software whose terms we confirmed against a primary source, usually the brand's own affiliate page, and recorded the platform their signup runs on. Programs known only from a network's bulk records are left out. The count updates with every data pass; the latest program was checked on Oct 5, 2026.

Affiliate software or a network?

Affiliate software

39%

The company rents a tool such as FirstPromoter, Rewardful or Tapfiliate and runs its own program on it. Affiliates apply to each program on that brand's own signup page; there is no platform account to join.

Network or partner marketplace

61%

The program sits inside a marketplace such as PartnerStack, Impact.com or Awin: an affiliate joins the network once, then applies to each brand inside it.

How we counted

Which programs: the 795 SaaS, marketing, hosting and security software programs in the directory whose terms we confirmed against a primary source, usually the brand's own affiliate page. We found each brand first, then read where its signup runs, so no platform's own catalog decided who is in the count.
The platform: where the program's signup runs (a PartnerStack application, a FirstPromoter or Rewardful portal, an Impact.com campaign page), recorded when the program was added and corrected since.
The brand's own site (434): the signup lives on the brand's domain and does not show the tracking software behind it. Many of these run on one of the platforms above under a custom domain, so each platform's share is a floor.
Left out: programs we know only from a network's bulk records, which would count how we imported data rather than what brands chose, and 9 whose platform we could not place.
What it is not: a census of every software company. It counts the programs an affiliate can join today that we track, and it updates with every data pass. See the methodology and the open data.
