The Hidden Cost of Building SaaS
Every SaaS founder underestimates their stack costs. A domain here, a database there, analytics, auth, email — it adds up fast. Before you write a line of code, know what your monthly burn will be.
Free Tiers Are Your Friend
Most services offer generous free tiers for early-stage projects. Vercel's hobby plan handles most startups until they hit serious scale. Supabase gives you a full PostgreSQL database for free. Use these until you have revenue to cover the bills.
Typical Solo Founder Stack
Minimal ($0-20/month): Vercel (free), Supabase (free), Clerk (free tier), PostHog (free).
Growing ($50-100/month): Vercel Pro, Supabase Pro, Resend for email, domain.
Scaling ($200+/month): Multiple services, higher tiers, AI API costs start dominating.
The goal: keep stack costs under 10% of revenue. If you're spending more than that on tools, either raise prices or find cheaper alternatives.
