Best tech stack for a SaaS product?
A proven, productive SaaS stack:
- Front end: React + Next.js + TypeScript
- Back end: Node.js (or Python if the product is data/AI-heavy)
- Database: PostgreSQL — Supabase gives you Postgres, auth, storage and real-time in one service
- Auth & tenancy: Supabase Auth / Clerk / Auth0, with Row Level Security to keep each customer's data separate
- Billing: Stripe subscriptions
- Background work: a job queue for emails, reports and imports
- Ops: Vercel or AWS, error tracking (Sentry), uptime monitoring, automated backups
Why: one language (TypeScript) end to end, a database that handles relationships and transactions properly, and managed services so a small team ships fast.
