I'm building a small SaaS app and need simple hosting with staging and production

A simple, low-ops setup for a small SaaS with staging + production is usually:

Good default stack

• Frontend / app hosting: Vercel, Netlify, or Render
• Backend / API: Render, Fly.io, or Railway
• Database: Managed Postgres on the same platform or Neon/Supabase
• File storage: S3-compatible storage (AWS S3, Cloudflare R2, or Supabase Storage)
• DNS / SSL: Cloudflare for DNS and basic protection

Easiest option

If you want the least hassle:

• Vercel for the app
• Neon for Postgres
• Cloudflare for DNS
• Use:
  • staging.yourdomain.com
  • yourdomain.com

Typical flow:

• Push to main → deploy to production
• Push to staging branch → deploy to staging
• Use separate environment variables and separate databases for each

Slightly more backend-heavy setup

If you have an API server:

• Render is very straightforward for:
  • web services
  • workers
  • cron jobs
  • preview/staging environments
• Use:
  • one service for staging
  • one service for production
  • separate databases

What to set up

At minimum:

• 2 environments: staging and production
• 2 databases: staging and production
• 2 sets of env vars
• Separate OAuth/app keys if you use third-party auth
• Separate email configs so staging doesn’t email real users
• Separate analytics if useful

Recommendation by simplicity

• Simplest overall: Vercel + Neon + Cloudflare
• Best for full-stack apps with jobs/APIs: Render + Neon + Cloudflare
• Very good but a bit more technical: Fly.io

A practical staging/prod pattern

• Production:
  • app.yourdomain.com or yourdomain.com
• Staging:
  • staging.yourdomain.com
• Branch mapping:
  • main → production
  • staging → staging
• Databases:
  • prod-db
  • staging-db

If you want, I can suggest a specific setup based on your stack (Next.js, Rails, Django, Laravel, etc.) and keep it very simple.
