A better development environment

Kool makes using Docker for local development easier, simpler, faster, and better.

Easier

Kool eliminates the learning curve and headaches of configuring Docker flags, fixing user permissions, and setting up local and global networks - to name just a few.

Simpler

Kool reduces the cognitive overhead of containerizing your stack by using a much simpler, more intuitive CLI interface for managing Docker containers and Docker Compose services.

Faster

Kool lets you spin up new local environments, switch between projects, share local changes with colleagues and clients, and deploy to the cloud – all in a matter of seconds.

Better

Kool provides custom Docker images optimized for local development and deployment, pre-built Presets with sane defaults for quickly setting up projects using popular frameworks – and more.

Any Language, Any Framework

Kool standardizes the way you work across all your tech stacks and projects.

Laravel
Symfony
Adonis
NestJs
NextJs
NuxtJs

A better development workflow

Kool CLI, Kool Scripts, and Kool Cloud work seamlessly together to create a more productive workflow for building and deploying containerized applications.
