Best SaaS Stack for Solo Developers (2026)

Q: What tools does a solo developer need to ship a product?

To ship a product as a solo developer, you need: GitHub for code, Vercel or Railway for hosting, Supabase or PlanetScale for your database, Stripe for payments, Sentry for error tracking, and PostHog for analytics. All of these have free tiers. Add Resend for transactional email and you have a complete stack at $0/month.

Q: What is the cheapest way to deploy a web app in 2026?

Vercel and Netlify offer free tiers for static sites and serverless functions. Railway offers $5/month in free credits for full-stack apps. Fly.io gives 3 shared VMs for free. For databases, Supabase free tier includes 500MB Postgres, and PlanetScale offers a free MySQL database. You can run a production app serving thousands of users for $0/month.

Q: Should solo developers use a BaaS or build their own backend?

Use a Backend-as-a-Service. Supabase gives you Postgres, auth, real-time subscriptions, storage, and edge functions for free. Building your own auth, file storage, and real-time infrastructure wastes weeks of development time. Use BaaS for everything except your core business logic. You can always migrate to a custom backend later if needed.
