Laravel or Django
Both can run a SaaS. I am faster and safer in Laravel: queues, billing packages, the PHP hiring pool in Morocco, my own production habits.
If your team is already Python-native, hire a Django person. Do not hire me to pretend.
Pick the person
A weak Laravel app loses to a strong Django one. Stack wars are a distraction from tenancy and backups.
My default
Laravel + PostgreSQL + Redis + React. That is what FRIGO-adjacent and SaaS work already uses.
FAQ
Will you maintain Django?
Not as a primary stack. I can read it; I will not own a Django rewrite.
