TL;DR : Gumroad has built-in affiliate management, free, no monthly fee. 5 minutes to set up a program with 30% commission. The non-obvious gotchas: which products show up, the minimum payout threshold, and the ToS edge cases that void commissions.

Why I set this up at Day 60 (and should have done it Day 1)

I'm running a 60-day indie iOS dev experiment. Just shipped 3 Gumroad SKUs ($19 + $15 + free lead magnet). Distribution is the bottleneck — I have ~600 unique site visitors in 3 weeks but no affiliate force.

If readers of my dev.to articles, my Substack subscribers, and my GitHub stargazers each had a tracking link with a real commission, I could 5-10× outbound reach. That's affiliate program logic 101.

Should have done this Day 1. Did it Day 60.
