Firebase: Your Serverless Backend

User accounts, real-time database, files, functions: everything an app needs behind the scenes, with no server to administer, for 0 € to start.

Instant lifetime access · 14-day money-back guarantee · Secure Stripe checkout

The problem

Your app needs a back office: accounts, data that syncs, files. The classic path (rent a server, administer it, secure it) is a full profession in itself.

Firebase does that job for you, free at the start. But badly configured, it's also the database left open to the entire world, or the surprise 400 € bill.

This course takes it in order: data, accounts, security rules (the real subject), functions, and the caps that guarantee the bill stays at zero.

This is for you if

  • You took the mobile course and want to master module 9 in depth
  • Your app needs accounts and sync
  • You want to understand security rules instead of copying them
  • You're building a SaaS and want a backend without DevOps

What you get

  • 8 modules, in English and French, at your own pace
  • Lifetime access, updates included
  • The course adapts: with AI (copy-ready prompts) or without
  • Support by messaging, answered by a real human
  • 14-day money-back guarantee (less than a third unlocked: see the Terms)

Questions

Before you decide.

Firebase or Supabase?

Both are good. Firebase is chosen here for its mobile maturity and because it's the one used in the flagship course; one module compares the two honestly.

Is it really free?

Up to volumes you won't reach before thousands of active users. Module 7 locks the bill at zero.

How do I access the course after buying?

Instant access: you receive a sign-in link at the email address used for payment, no password to create. All your courses live in one place, under one email.

What if it is not for me?

14-day money-back guarantee: one email, full refund, as long as less than a third of the modules have been unlocked (details in the Terms of sale).
