Sometimes I have a new genious app idea, but when I start coding it I get demotivated with re-creating all the same functionality for the 100th time:

• Authentication, SSO
• Teams and Multitenancy
• Roles (Authorization)
• Payments & Subscriptions
• Responsive layout
• UI elements
• Internationalization
• CI setup
• Tests for all the basic functionality

These days there are many starter kits.
I will try to make a general overveiw and comparison.

I will also try using and understanding the recently open sourced Bullettrain SaaS template, that I have high hopes for!
