Firebase vs while: which one to choose when your AI agent deploys?

What changes between Firebase and while

What matters	Firebase	while
Who it’s for	Web and mobile apps built on Google’s services: database, sign-in, hosting1	People who build their apps with an AI agent, solo or as a team
Your AI agent	An MCP server with about 70 tools, which deploys and can delete Firestore data2	Connected over MCP, with OAuth: it deploys, creates the database, reads the logs and fixes things
What protects production	Your Firebase account’s permissions, and your approval in your AI tool2	Sensitive actions, like deleting a production database, wait for a person
The database	Firestore, or PostgreSQL through SQL Connect: daily backups and point-in-time recovery on the pay-as-you-go plan8, none during the free trial3	PostgreSQL in while, backed up every day, with point-in-time recovery
Who opens your app	No setting to protect a site: Firebase advises filtering visitors in the code4	Everyone, a password, or the company account with the Pro plan
In France	The database yes, if you create it in France. The server for dynamic apps no: the Netherlands is the closest5	Yes, with Nextmap, a French company
To get started	Free for a static site. A dynamic app requires the pay-as-you-go plan6	A trial without an account. Then €0 to get started, and €13.75 per month for an app and its database

Firebase, all of Google for your app

Firebase brings together what a web or mobile app needs: a database, user sign-in, and hosting on a global CDN with one-click rollback^1,7. For agents, Firebase has an MCP server with about 70 tools², remote servers and official skills.

With while, your AI agent does the rest

• No server to maintain. No system to update, no disk to watch, no certificate to renew: your agent deploys, and the rest is taken care of.
• Your databases are backed up for you. Every day, with point-in-time recovery, and a production backup tested every day.
• Nothing serious happens without you. Deleting a production database waits for your approval, before it runs, and every action is recorded in a signed activity log.
• Your keys stay secret. Your app uses them, your agent never sees them.
• Your colleagues sign in with the company account. Google Workspace or Microsoft 365, on the Pro plan, with no sign-in page to code.

Moving from Firebase to while

Take over your app

Your agent takes over your code, writes while.yaml and deploys the app.

Copy your data

Your agent exports your PostgreSQL tables, or your Firestore collections, then loads them into a PostgreSQL database on while.

Carry over your variables

Your agent carries your settings over to while. You enter your secret keys yourself: it never sees them.

Which one to choose

• Choose Firebase if your mobile app already lives on Google’s services: database, sign-in, notifications.
• Choose while if your web app must run in France, as it is, with its PostgreSQL database, and your AI agent must not break anything without you.

Next steps

• Deploy a Next.js app
• Deploy a Node.js API and its PostgreSQL database
