Frequently asked questions
Can I build a SaaS product with an app builder?
Yes. Modern builders support authentication, subscription billing, multi-tenancy, and API integrations required for SaaS. Goodspeed generates apps with RevenueCat subscriptions built in.
How do app builders handle SaaS billing?
Most integrate with Stripe or RevenueCat for subscription management. Goodspeed includes RevenueCat integration and paywall components out of the box.
Can I build a mobile SaaS app?
Yes. Goodspeed generates native mobile SaaS apps with in-app purchases through App Store and Play Store billing. This can be more profitable than web-only SaaS for consumer products.
What about multi-tenancy?
Supabase Row Level Security (used by Goodspeed) provides tenant isolation at the database level. Enterprise platforms like OutSystems offer more sophisticated multi-tenancy patterns.
