What it does
Upsun Cloud is an application hosting platform built around Git workflows and declarative configuration. A project can define runtimes, connected services, and routes in a versioned YAML file, then deploy through the Upsun CLI or Console. GitHub, GitLab, or Bitbucket integrations can mirror an external repository and create preview environments for branch or pull-request changes. It is managed application hosting, not a general-purpose VPS.
Put the runtime configuration beside the code
The first-project guide asks for an Upsun account, a supported runtime, and Git installed locally. Create a project, run upsun init to generate .upsun/config.yaml, and use the file to describe the app, services, and routes. Commit the configuration with the application and deploy with the documented upsun push flow. Alternatively, connect an existing GitHub, GitLab, or Bitbucket repository; Upsun mirrors it and can create preview environments from branch and pull-request activity.
Reconcile project fees with resource use
Upsun's pricing page describes a 15-day trial and monthly credit for one project fee and one user license. It also states that provisioned resources are billed per second and lists separate project and user charges. The introductory credit is not evidence of a permanent free plan. Estimate a deployment using the project's actual runtime and service configuration; this listing does not calculate a workload bill.
Strengths
- Runtime, service, and route configuration can be committed in `.upsun/config.yaml` with the application.
- Repository integrations can produce preview environments from branches and pull requests while the external Git provider remains the source of truth.
- The official site documents Console, CLI, and API management paths.
Watch out for
- The documented local deployment path requires Git and a platform configuration file.
- A project fee and user charge sit alongside resource usage, so the service is not represented by one flat application price.
Best for
- Deploying a Git-managed web application with its runtime and connected services described in version control.
- Creating branch or pull-request preview environments while keeping an external repository as the source of truth.
- Teams seeking managed application hosting across the cloud providers listed by Upsun.
