Upsun

Upsun is the platform-as-a-service formerly known as Platform.sh, renamed in 2025. It is language-agnostic — PHP, JavaScript and Python are documented, with framework guides for Laravel, Symfony, Django, Express and Next.js, and tutorials for WordPress, Drupal, Magento and Shopware. A project is described in YAML files covering routes, services and application containers, and a branch can be built into a full environment from that description.

There are no named plans. Resources are provisioned per project and billed by the hour, metered per second, on top of a flat per-project fee and a per-user licence. A trial runs without a credit card. Upsun describes its customers as teams running regulated and production workloads in finance, SaaS and higher education.

Worth knowing

The entry cost is not a single figure. The floor is the project fee plus at least one user licence before any resources are provisioned, and the bill on top depends on how the YAML is written.

The configuration model is a commitment. Routes, services and containers are described in Upsun-specific YAML, so moving an application on or off the platform means rewriting that layer rather than porting it.
