How do I build a referral program into my product technically without over-engineering it as a solo dev?
The short answer
For your first version, skip the referral SaaS and the fancy attribution: a unique referral link per user, a simple table logging who invited whom, and a manual or semi-automated reward is enough to learn whether referral even works for you. Reach for a dedicated referral tool only once you've proven people share and you're drowning in manual reward fulfillment. Over-building a rewards engine before you have referrers is the classic solo-dev trap, ship the ugly version, measure share rate, then invest.

Why we picked it
This is a hands-on walkthrough, not theory: it shows the actual pieces you need to ship the minimal version, a user schema, UUID-based referral code generation, and a registration endpoint that records who referred whom and credits the reward. It stays deliberately small (no configurable rewards, no heavy auth) which is exactly the right altitude when you are a solo dev trying to get a working referral loop live rather than a perfect one.
Why we picked it
This is the canonical source of the ship-ugly-first idea, the LinkedIn co-founder's own essay behind the line about being embarrassed by your first version. For a solo dev deciding how much to build into a referral program before shipping, this is the judgment call at the heart of the question, launch the rough version and let real usage tell you what to add. Hoffman also draws the line on where ship-fast should not apply, which keeps it honest rather than a slogan.
Why we picked it
Once your referral program needs commission tracking, coupon links, and payouts tied to real revenue, hand-rolling all of that stops being worth your time, and this is the reference point for what an off-the-shelf tool costs and does. Rewardful plugs into Stripe or Paddle with little to no code, so seeing its plans (starting at 49 dollars a month) helps you judge the moment when buying beats building.
From
Rewardfulby RewardfulPricing page, plans from 49 dollars a month
Off-the-shelf referral and affiliate tools start around 49 dollars a month, so the build-versus-buy line usually sits at when you need real commission payouts, not at day one
It is built around Stripe and Paddle, so its value depends on whether your billing already runs through those
Use it as a spec even if you build your own: coupon links, cookie windows, and commission rules are the features you will eventually need to cover
