Instantly View and Run GitHub Code Online with a Single Keystroke

Online Code Viewing

Press the period key "." on any GitHub repository page and a VSCode‑like editor opens, allowing you to read source files directly in the browser. The service is accessed via https://github.dev/ without needing to navigate to the URL manually.

Online Documentation Preview

For HTML documentation files on GitHub, use https://htmlpreview.github.io/. Append the raw GitHub URL of the HTML file, for example

https://htmlpreview.github.io/?https://github.com/AdoptOpenJDK/openjdk-jdk8u/blob/master/README-builds.html

, to render the document nicely in the browser.

Online Code Execution

Use https://www.gitpod.io/ to launch a full cloud development environment for any GitHub repository. Enter the repository URL (e.g., the Spring‑Petclinic project) and Gitpod opens the project in an online IDE where you can install extensions and run the code.

Summary

github.dev

– press the period key to view source code instantly. htmlpreview.github.io – render GitHub‑hosted HTML files directly. gitpod.io – spin up a cloud IDE and run projects without local setup.
