 Gitpod is a web-based IDE. As such one would think it only works for web-based projects or anything else that does not require a native UI. However, there’s still a plethora of native UI applications around and many of them are here to stay. In this article we’ll go through how to use Gitpod for developing native desktop UI applications.

 A few days ago [Gero introduced Docker builds to Gitpod](/blog/docker-in-gitpod) with which you can bring your own Dockerfile (instead of a pre-built image), and Gitpod will build the image for you. We’ll use that feature to setup a cloud-based development environment for native UI applications.

 Gitpod starts a new workspace, which is a Linux-based cloud container, and provides access to it via a VS Code powered online IDE. Workspaces are started on demand and automatically shut-down if you don’t use them. They are continuously replicated and never deleted, so you always can restart a workspace later from [your Gitpod dashboard](https://gitpod.io/workspaces/).

 ### Reviewing a Pull Request
 
 As I’ve mentioned at the beginning Gitpod treats each GitHub repository as a project. Actually, it is even smarter and can figure out from any GitHub URL which branch should be opened and how.
 
 Let’s go to the pull request page on GitHub and prefix its URL with gitpod.io/#, just like we did initially:

 ### Showcasing Node.js applications
 
 You can take a complete snapshot (clone) of your workspace, even including your IDE layout, and share it as a link. Think about workspace snapshots like code snippets on JSFiddle. It is useful in the same way: to share reproducible examples on issues, Stack Overflow answers, for tutorials and workshops. But at the same, you share the complete development setup and present it in the appropriate way.
