Developer Experience Matters

Moving forward DX through Open Source

We are a community of developers passionate about open source and developer experience. We always seek new contributors to help us build the best open-source projects.

An open-source project born from the need to provide a better developer experience

The kool CLI: In the center of our efforts to improve DX, the kool CLI enables developers to work with Docker containers for local development environments. It offers a convergent approach to software development, where you can use the same tools and practices for local development and future cloud deployment.
Ecosystem that follows: We also have a growing ecosystem of companion tools and helpers that help you improve your DX, all of them open-source and available on GitHub. We always seek new contributors to help us build the best open-source projects. We have optimized Docker images for PHP, Node, Java, and we got Helm charts, useful containerized microservices, VPN/SSH tunneling through containers, and more.

Explore all of our open-source initiatives

It's a way to help evolve and spread our approaches for a better Developer Experience to a larger audience, supporting developers every step of the way from local development to cloud deployment.

Active maintainers: We continuously update and evolve our projects.
Documentation: In progress: documentation for all projects.
Community: We got a growing community over Slack.
Join us: Got something to contribute? You are most welcome!
