I built REFER, a tool that helps people automatically share their referral codes where others are searching for them. It’s not a marketplace or a link tree—users just enter the codes they already have (for apps like Webull, Rakuten, Robinhood, etc.), and REFER distributes them for discoverability. The goal is to make it easier for people to earn from referral programs without constantly promoting links themselves.
Why I built it: I noticed a lot of folks—including creators and casual users—have valuable referral codes sitting unused. Most people either don’t know where to post them, or they end up buried in social media bios or YouTube descriptions. I wanted to make something that quietly works in the background to surface these codes without requiring extra effort or marketing.
I designed and built REFER solo. It uses Next.js, TypeScript, Prisma, MongoDB, Stripe (for optional paid tiers), and Auth0 for authentication. All code is deployed on Vercel.
What's different: All codes are continuously re-shared over time, not just the newest or most active—everyone gets a fair chance at visibility.
It’s focused purely on automation and visibility—set it once and forget it.
There’s a free tier, and you can try it here: https://www.refer-app.com/. You do need to sign up to add codes, but I’d be happy to set up a demo or provide a walkthrough if there’s interest.
Happy to answer questions, share more technical details, or hear feedback (especially the critical kind).
Thanks!
