Contribute.dev is a new platform that aims to make open-source contributions easier by providing a list of welcoming projects with ready-to-code Gitpod setups. The setup for these listed projects is automated, allowing users to get a fully working developer environment within seconds using just their browser. Users can contribute to the project of their choice by clicking on the "Open in Gitpod" button and making changes directly from the full-featured IDE. If a desired project isn't available, users can file an issue with a link to their repository for assistance in setting it up.
