Adding Features to Your Firebase Studio App
What Firebase Studio can't build for you and how to add it. From payments to email to real-time features, a guide for founders.
What Firebase Studio can't do well
Firebase Studio handles real-time data and auth well but complex business logic, third-party integrations, advanced data transformations, and background processing require Cloud Functions that are harder to build and debug than the client-side Firebase experience
Features you probably need
Stripe payment integration via Cloud Functions with webhook handling. Push notifications via Firebase Cloud Messaging. Full-text search with Algolia or Typesense (Firestore doesn't support full-text search natively). Scheduled Cloud Functions for periodic data processing. File processing pipelines using Cloud Functions triggered by Storage uploads
Payments (Stripe)
Almost every SaaS app needs payment processing. Stripe is the standard — it handles credit cards, subscriptions, invoices, and payouts. The key pieces: a checkout flow for collecting payment, webhooks to update your database when payments succeed or fail, and a customer portal for managing subscriptions. Firebase Studio might generate a basic checkout page, but the webhook handling and subscription lifecycle management usually need to be built by hand.
Authentication
Your app needs user accounts with secure login. The easiest options: NextAuth (for Next.js), Supabase Auth, or Clerk. These handle email/password login, social login (Google, GitHub), password resets, and session management. Don't build auth from scratch — the security implications are too complex for a first implementation.
Email notifications
Transactional emails — welcome emails, password resets, order confirmations — require an email service provider. Resend is the simplest to set up, SendGrid is the most established, and Amazon SES is the cheapest at scale. You'll need email templates, a sending service, and proper DNS configuration (SPF, DKIM) so your emails don't land in spam.
When to hire help
If a feature requires deep technical expertise (payment compliance, data privacy, real-time systems), it's faster and safer to get professional help than to iterate with AI tools. Our team adds features like these to Firebase Studio apps every week — we know the patterns and the pitfalls.
