Frequently asked

What is the best tech stack for a solo SaaS builder in 2026?

There is no single best stack. Pick one tool per layer and ship. A common, cheap setup: an AI coding tool (Cursor or Lovable), TanStack Start or Next.js, Supabase for database and auth, Cloudflare or Vercel for hosting, Stripe or Lemon Squeezy for payments, and Resend plus beehiiv for email. Each guide compares the real options for that layer.

What is the cheapest way to build a SaaS?

Cloudflare Pages free tier plus Supabase free tier puts hosting, database, and auth at $0 for low traffic. Add one AI coding tool (around $20/month) and a payment tool that charges per transaction (Stripe or Lemon Squeezy). You can launch for under $25/month.

Do I need a paid SaaS boilerplate?

Only if you want a proven head start, patterns, and a community. AI coding tools like Cursor and Lovable now scaffold the same setup for free. Pay for a boilerplate to save time, not because you cannot build it yourself.

Do I need both website and product analytics?

Yes, if you have a marketing site and an app. Use Plausible for the marketing site and PostHog for in-app behavior. PostHog's free tier covers most early-stage SaaS.

How are these tool picks chosen?

No sponsorships and no affiliate bias. Each guide compares the real options on pricing, limits, and fit for solo builders, then gives a clear pick. KILL and 'use the free one' verdicts are included when that is the honest answer.
