FAQ
Why choose Base44 for building a web app or SaaS MVP?
Base44 provides a modern, flexible environment for constructing web app frontends and full-stack tools quickly. When paired with a dedicated backend like Xano, it yields ultra-fast page speed, secure database architecture, and complete freedom from restrictive workload penalties.
Can you connect my Base44 web app to an external Xano or Supabase backend?
Yes! As a base44 developer, I specialize in decoupled web architecture. I build your database schemas, authentication workflows, and custom logic in Xano or Supabase, connecting them seamlessly to your Base44 frontend via REST APIs.
Q: How do you handle Stripe payments and user subscriptions in Base44?
I route payment events through secure Xano or server-side webhooks using Stripe Checkout and the Stripe Customer Portal. This automatically manages subscription upgrades, downgrades, and user access levels inside your base44 web app.
Can you build custom AI capabilities using OpenAI inside Base44?
Absolutely. All OpenAI or Claude API calls, secret keys, and token-usage limits are handled securely on the backend. This protects your API credentials while delivering dynamic AI features directly to your Base44 user interface.
Will my Base44 application be mobile-responsive?
Yes. Every base44 web app layout, client portal, and dashboard I construct is engineered with mobile-first responsiveness for flawless desktop, tablet, and smartphone viewing.
