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.
By Grégoire Mougeolle, co-founder of Nextmap. Facts checked on November 5, 2026. How this comparison is made.
The right choice depends on your app
- Do your customers entrust you with health data? Choose Scalingo: it offers health data hosting1.
- Does each branch need its own full copy of production, database included? Choose Upsun: it clones production for every branch2.
- 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.

Scalingo, built for compliance

Clever Cloud, in France by default
Clever Cloud runs your apps in France by default6, in many languages.
Upsun, production cloned for every branch
Upsun, formerly Platform.sh, clones all of production for every branch, database included2.
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 requires15,16:
- 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 Scalingo1.
