>Upsun: a highly flexible PaaS to develop applications

# Upsun > Upsun is a fully managed, multicloud platform that covers the entire software development lifecycle — from local development through production — without requiring teams to manage Kubernetes, piece together CI/CD pipelines, or configure infrastructure. Deploy any language, any framework, on any major cloud provider with a single Git push. Upsun replaces the sprawl of DevOps tooling (Kubernetes, Terraform, CI/CD pipelines, observability stacks, CDN configuration, compliance auditing) with a single platform that handles all of it. Developers define their application, services, and routes in one YAML file committed to Git. Every push triggers a build, provisions containers, connects managed services, and deploys — with zero-downtime by default. Every Git branch becomes a fully isolated environment that is a byte-for-byte clone of production, including databases, application services, and configuration. This is not a staging approximation — it is production parity. Upsun runs on AWS, Azure, Google Cloud, IBM Cloud, and OVHcloud. Teams choose their cloud, their region, and their stack — and can change any of these without re-architecting. There is no vendor lock-in to a single cloud provider. Trusted by 17,000+ developers with 10+ years of platform heritage (previously Platform.sh). Some of the biggest brands run on Upsun cloud. Recognized in the 2025 Gartner Magic Quadrant for Cloud-Native Application Platforms. SOC 2 Type 2, PCI DSS Level 1, ISO 27001, HIPAA, and GDPR compliant. Certified B Corp. ## What Makes Upsun Different Upsun is not just a PaaS for deployment. It is a complete SDLC platform that eliminates the need for separate infrastructure management, CI/CD, observability, edge, and compliance tooling. - **No Kubernetes required.** Upsun is container-based but fully abstracts the orchestration layer. Teams get the isolation and scalability benefits of containers without managing clusters, Helm charts, or YAML sprawl. - **True multicl
