About Scalingo
Scalingo lets developers deploy at lightning speed while keeping data sovereign in Europe. It is the first European Platform as a Service certified for Health Data Hosting (HDS) and ISO 27001, with datacenters located in France and a SecNumCloud region for regulated workloads that require the highest French government assurance level.
The platform supports git-based deployments, autoscaling triggered by metrics, zero-downtime rolling releases, managed databases with point-in-time recovery, and automatic failover for high availability. Encryption at rest and in transit is on by default, and managed vector databases such as pgvector and OpenSearch KNN make Scalingo a natural fit for AI-driven applications built on PostgreSQL and MongoDB.
Key benefits:
- Git-based deploys that ship code to production in under a minute
- Autoscaling driven by CPU, memory, and request-rate metrics
- Managed databases with backups, point-in-time recovery, and HA failover
- Vector search through pgvector and OpenSearch KNN for AI workloads
- SecNumCloud region for public-sector and highly regulated applications
Scalingo is headquartered in Strasbourg, France, with all datacenters located on European soil and all data subject to European jurisdiction only. The platform holds ISO 27001 and HDS certifications, offers a SecNumCloud IaaS region, and is fully GDPR-compliant, making it a genuine sovereign alternative to US hyperscaler PaaS offerings.
Trusted by the French Ministère de l'Intérieur handling 20,000 requests per minute, Yespark with 20+ daily deployments, and healthcare AI platform Heloa Health.
Why choose Scalingo over Fly.io?
The decisive argument is data jurisdiction. Fly.io is headquartered in US, which means personal data processed through it can be subject to non-EU legal regimes: the US CLOUD Act, FISA 702, or similar laws depending on the provider. After the 2020 Schrems II ruling, EU organisations must carry out a transfer impact assessment for every such data flow.
Scalingo removes that overhead. As a France-based provider, it operates natively under GDPR, and data stays inside the EU/EEA by default. For regulated sectors such as health, public administration, and finance, that's not a nice-to-have but a requirement. For everyone else, it's concentration-risk insurance: you avoid depending on a single non-EU jurisdiction that can change the rules without warning.
