Kool
Command-line tool for Docker-based local development environments, with optional deployment of containerized apps to the cloud.
Kool is a command-line tool that runs Docker-based local development environments for web projects. The install script downloads the kool binary from the project’s GitHub releases to the developer’s machine, and the tool needs Docker Engine and Docker Compose running there. The docs cover Linux and macOS directly; Windows is supported only through WSL.
The CLI is MIT-licensed and maintained by Kool Dev, a company based in Brazil. The same company runs Kool Cloud, a managed cloud, and an option to deploy to a cloud or VPS the user brings. Those hosted products sit next to the open-source CLI and are separate from it.
Worth knowing
Windows users need a WSL environment with Docker available inside it before the CLI can run; the CLI does not run natively on Windows.
Kool Cloud is a hosted product with its own pricing reference page. The CLI is usable without it.
