# The best French hosting providers for a B2B SaaS in 2026

Before signing, your B2B customers want to know where their data will be, and who will be able to touch it. Here are the French hosting providers that answer those questions, and what each one allows when your AI agent is the one deploying.

## The right choice depends on your app

- **Do your customers entrust you with health data?** Choose Scalingo: it offers health data hosting (source 1).
- **Does each branch need its own full copy of production, database included?** Choose Upsun: it clones production for every branch (source 2).
- **Do your customers ask for an audit log, and for their data in France?** Choose while: every action on production is recorded in a signed audit log, which the Enterprise plan keeps for 7 years.

## The comparison

| Host | In France | The company behind it | Your AI agent | To get started |
|---|---|---|---|---|
| Scalingo | Yes (source 3) | French, in Strasbourg (source 4) | No official MCP server: the command line | €7.20 for the container and €7.20 for the database, per month (source 5) |
| Clever Cloud | Yes, by default (source 6) | French, in Nantes (source 7) | A local MCP server, still young (source 8) | From €4.50 for the app (source 9), and the database free on DEV, then €4.90 (source 10), per month |
| Upsun | Yes, two regions (source 11) | French, formerly Platform.sh (source 12) | An MCP server in beta, read-only by default (source 13) | First project and first user free, with conditions. Beyond that, €9 per project and €10 per user, per month, plus resources (source 14) |
| while | Yes | French, Nextmap | An MCP server with OAuth: sensitive actions wait for your approval | €0 to get started, then €13.75 per month for an app and its database |

## Scalingo, built for compliance

Scalingo is built for compliance, with ISO 27001 and health data hosting, and it responds to critical incidents in under 15 minutes on average (source 1).

## Clever Cloud, in France by default

Clever Cloud runs your apps in France by default (source 6), in many languages.

## Upsun, production cloned for every branch

Upsun, formerly Platform.sh, clones all of production for every branch, database included (source 2).

## while, your SaaS in France, deployed by your agent

Your AI agent deploys your SaaS over MCP, and everything runs in France, with Nextmap, a French company. Sensitive actions, like deleting a production database, wait for your approval, every action is recorded in a signed audit log, and your keys stay out of your agent's reach. With the Enterprise plan, this log is kept for 7 years and goes to your SIEM: enough to answer your customers' security questionnaires.

## What while's contract says about your data

Your customers will ask for your host's data processing agreement. while's is annexed to its terms, as article 28 of the GDPR requires (sources 15 and 16):

- you are the controller, and Nextmap, which makes while, is your processor;
- your data is hosted in France; one of Nextmap's subprocessors may process it in another country of the European Union, and it only leaves the Union in compliance with the GDPR, after you have been informed;
- every new subprocessor is announced to you by email 15 days in advance: you can object, and terminate at no cost if Nextmap keeps it;
- a data breach is notified to you without undue delay, by email;
- you can audit while, first on documents, then on site once a year, at your expense, with 30 days' notice;
- at the end of the contract, you get your data back, then Nextmap erases it, backups included.

while does not accept health data: for that, choose Scalingo (source 1).

## Questions

### Is hosting in France enough for GDPR?

It's part of the answer: GDPR covers all of your data processing. But hosting in France, with a French provider, is often the first question your B2B customers ask.

### What can I show a customer who sends a security questionnaire?

On while, the signed audit log of every action on production, and with the Enterprise plan, its export to your SIEM and its retention for 7 years.

### Which ones are French?

All four: Scalingo, Clever Cloud, Upsun and while, made by Nextmap.
