FAQ
Can I build a SaaS for free?
Yes. Vercel (hosting), Supabase (database + auth), Stripe (payments, pay per transaction), Resend (3,000 emails/month), and Plausible or PostHog (analytics) all offer free tiers sufficient for launching. You only pay when you have real usage.
What is the best free database for developers?
Supabase offers the most generous free database tier: 500MB PostgreSQL, unlimited API requests, and 50,000 monthly active auth users. Neon offers 500MB serverless Postgres with scale-to-zero. Turso offers 9GB across 500 SQLite databases.
What is the best free hosting for web apps?
Vercel is the best free hosting for Next.js apps with 100GB bandwidth and automatic SSL. Cloudflare Pages offers unlimited bandwidth on its free tier. Both support custom domains and automatic HTTPS.
Are free tier tools reliable for production?
Free tiers from established providers like Vercel, Supabase, and Stripe are production-ready. The main limitations are usage caps (bandwidth, database size, API calls) and rate limits. Most indie developers run on free tiers until they have paying customers.
