Firebase gives you parts.
Piezas gives you capabilities.

Firebase says it helps you and AI tools build apps, and it does — with excellent parts: a database, sign-in, file storage, and somewhere to run your own code. The business logic still gets written, by you or your AI tool. On Piezas it already exists.

the short answer
The question is not whether your AI tool can build a reservation system on Firebase. It can. The question is whether the logic it improvises handles two people booking the same slot, a double click that charges twice, and the reminder that silently never sends. On Firebase those are your code. On Piezas they are ours — written once, and fixed under every app at the same time.

Firebase
What you get
Finished capabilities: user accounts, records and documents, bookings, invoicing, forms, scheduled work, notifications, audit trails.
Parts to build with: a database, sign-in, file storage, somewhere to run code, analytics, crash reporting, and Google's AI services.
How your data is held
Related records stay consistent with each other — an invoice and its line items cannot drift apart.
Flexible documents. Keeping related records consistent is your app's job, which means your AI tool's job.
Where the business logic lives
Inside the capabilities. Availability, double-booking, retries, and reminders ship built in.
In code you deploy and debug yourself.
What it costs
A flat monthly plan per number of apps. You can predict the bill.
Metered by usage. Powerful at scale, and famously easy for one runaway loop to turn into a surprise bill.
Signing in your customers
Accounts, sign-in, email verification, and lockout come managed, wired to everything else.
Firebase sign-in is genuinely best in class for consumer apps — social and phone sign-in, generous free tier.
Getting your data out
Your app talks plain web requests; records export as spreadsheet or JSON files.
The data model is Google's own. Moving off means redesigning how your data is stored.

When Firebase is the right choice

Consumer mobile apps that want the whole Google kit: analytics, crash reporting, push notifications.
Live, collaborative experiences — chat, presence, shared cursors.
You are already deep in Google Cloud and want one bill.
Prototypes riding the free tier.

When Piezas is the right choice

✓You have no backend engineer, and no plans to hire one.
✓Business software with records that relate to each other: bookings, invoices, cases, clients.
✓A predictable monthly bill matters more than metered scale.
✓You want an audit trail and each customer's data kept separate, without configuring it yourself.

Firebase's own homepage now says the future is you and AI tools building apps together. We agree. The only disagreement is what they should build on: parts someone still has to assemble correctly, or capabilities that are already correct.
