Our mission for SupaSaaS
David Flagg
Founder & Maintainer of SupaSaaS @ Webenova
I built SupaSaaS after repeatedly rebuilding authentication, Stripe subscriptions, and email systems for real SaaS projects.
This is the exact setup I now start every new product with — packaged so other developers can skip weeks of boilerplate work and ship faster.
