Platform comparison

FlatRun vs Coolify

Both platforms deploy applications to servers you control. The difference is how they automate operations and preserve control as the server fleet grows.

Choose FlatRun when

  • Production changes must be previewed before they run.
  • Users and peer servers need deployment-level permissions.
  • Host and container limits should drive scaling decisions.
  • The same governed operations must work through the panel, CLI, CI, assistant, and MCP.
  • Deployments must remain ordinary Compose projects on disk.

Choose Coolify when

  • Your main workflow starts from a Git repository and application build.
  • You want Coolify Cloud as an alternative to running the control plane yourself.
  • You prefer to design multi-server load balancing outside the platform.
  • You already use Coolify resources and want its official CLI for automation.
