I'm building a small SaaS and need something easy to integrate and debug.

If you want easy to integrate and debug for a small SaaS, I’d usually recommend picking a stack with:

• Simple auth
• Clear logs
• Good local dev experience
• Managed infrastructure
• Minimal moving parts

A very practical setup is:

Good default stack

• Frontend: Next.js
• Backend/API: Next.js API routes or a small Node/Express service
• Database: Postgres
• ORM: Prisma
• Auth: Clerk, Auth.js, or Supabase Auth
• Hosting: Vercel for app, Supabase/Neon/Railway for Postgres
• Logging/Errors: Sentry + structured logs

Why this works well

• Easy to integrate: lots of docs, common patterns
• Easy to debug: local dev is straightforward; Prisma and Next.js give readable errors
• SaaS-friendly: supports subscriptions, users, teams, and dashboards well
• Low ops burden: mostly managed services

If you want the simplest possible path

Use:

• Next.js
• Supabase
• Stripe
• Sentry

That gives you:

• auth
• database
• file storage if needed
• payments
• error tracking

Debugging tips

• Use one source of truth for env vars
• Add request IDs to logs
• Keep API contracts typed
• Make sure local/staging/prod configs are separate
• Use Sentry from day 1

If you want, I can suggest:

1. a full SaaS starter stack,
2. a minimal MVP architecture, or
3. a recommended stack based on your language preference (JavaScript, Python, etc.).
