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

What changes between Upsun and while

What matters	Upsun	while
Who it’s for	Teams that want a multicloud PaaS, configured in a YAML file1	People who build their apps with an AI agent, solo or as a team
Your AI agent	An MCP server in beta, read-only by default2	Connected over MCP, with OAuth: it deploys, creates the database, reads the logs and fixes things
What protects production	Read-only by default. Once writing is turned on, it can delete permanently2	Sensitive actions, like deleting a production database, wait for a person
The database	Managed PostgreSQL, one backup per day kept for 2 days by default3	PostgreSQL in while, backed up every day, with point-in-time recovery
Who opens your app	A username and a password, or a list of IP addresses4	Everyone, a password, or the company account with the Pro plan
In France	Yes, in two regions5	Yes, with Nextmap, a French company
To get started	First project and first user free, under conditions. Beyond that, €9 per project and €10 per user, per month, plus resources6	A trial without an account. Then €0 to get started, and €13.75 per month for an app and its database

Try while on your app, without an account. Copy the instructions

Upsun, production cloned for each branch

Upsun clones all of production for each branch, database, files and services included: a real copy to try things out before merging¹. Born as Platform.sh in France, it runs on five major cloud providers, including two regions in France, with ISO 27001 and SOC 2^1,5.

With while, your AI agent does the rest

• Your agent deploys, over MCP. It writes while.yaml, creates the database, reads the logs and fixes things, with no command line to learn.
• 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.
• A mistake is quickly undone. In the 30 minutes after a deployment, the previous version comes back in a second, and your database goes back to a precise moment.

Moving from Upsun to while

Take over your app

Your agent reads .upsun/config.yaml, writes while.yaml and deploys the app.

Copy your PostgreSQL database

Your agent exports the database with pg_dump, then loads it into 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 Upsun if you want a proven multicloud PaaS, with a full copy of production for each branch.
• Choose while if your AI agent is the one deploying, and you want to be sure it can’t break anything in production without you.
