The best sovereign hosting for business apps in 2026

The right choice depends on your app

• Do your apps handle health data, or do your customers require certifications? Choose Scalingo: it is ISO 27001 certified and offers health data hosting¹.
• Does your team prefer to assemble its own European cloud? Choose Scaleway: containers, database and network are separate products there, with a region in France².
• Do your teams deploy with their AI agent, and does IT need to stay in control? Choose while: each app opens with the company account, and sensitive actions wait for a person.

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

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 average¹.

Upsun, production cloned for every branch

Upsun, formerly Platform.sh, clones all of production for every branch, database included¹³.

Scaleway, the European cloud you assemble yourself

Scaleway runs your containers from zero to 200 instances depending on demand, in a European cloud².

while, your teams’ apps under IT’s control

Your teams deploy their apps with their AI agent, over MCP, and IT stays in control. Each app opens with the company account, whether Google Workspace, Microsoft Entra or Keycloak, without a line of code. Sensitive actions, like deleting a production database, wait for a person, permissions go down to the table, and every action is recorded in a signed audit log. With the Enterprise plan, high availability is there by default, the audit log goes to your SIEM and is kept for 7 years, and a production deployment can require two approvals. Everything runs in France, with Nextmap.
