Programming Playgrounds 🧪

Remote sandbox environments for learning and experimenting without worrying about setup and cleanup. Run anything on vanilla Linux VMs, get a fresh Docker host or Kubernetes cluster in seconds, publish ports, collaborate via sharing terminal sessions, SSH from the command line, and more.

Pro Tip: Build your own playgrounds to automate repetitive setups, easily share reproducible environments with your teammates, or include in your blog posts, demos, conference talks, GitHub projects or issues.
