Indie Hacker SaaS Stack 2026
The tools landscape for indie hackers has changed dramatically in the past year. AI coding tools like Cursor and Claude Code cut development time by 3-5x. Free tiers from Supabase, Vercel, and Resend got even more generous. And boilerplate starters mean you can go from idea to deployed SaaS in a weekend.
This guide is the stack we'd use if starting a SaaS from scratch today, based on what successful indie hackers on podcasts like Indie Hackers, My First Million, and Build in Public Radio actually use — not what has the best affiliate program.
The Problem
80% of indie hackers take 1+ month to ship their first MVP. The bottleneck isn't coding — it's picking the wrong tools and over-engineering before you have a single paying user.
The Solution: $0 to MVP
Every tool below has a free tier generous enough to reach product-market fit. You shouldn't spend money on infrastructure until you have paying customers.
