Code reviews, editor updates and custom themes

CodeSandbox is becoming the all-in-one tool for faster code reviews! But that's not all that's new.
Code reviews, editor updates and custom themes

Hi there! We are very excited to be back with a fresh update (hopefully, fresh enough to help you beat the heat).

We will keep it short and sweet, so let's get going!

What's new?


Full code reviews in CodeSandbox 🔥

After talking with hundreds of developers, we came to realize that the typical code review process is... a mess. So, we are making CodeSandbox the all-in-one tool for code reviews. See our getting started video to try it out.


Update the cloud editor to use VS Code web

We have overhauled our cloud editor to use VS Code web, which brings several new improvements including: more complete language support; support for LSP actions that require multiple files; improved syntax highlighting; git dirty decorations; file navigation history.


Cloud editor layout updates

We have shipped a bunch of quality-of-life features to improve the DX of our cloud editor. These include automatically killing closed tasks and terminals; fixing panels for the editor, shells and DevTools; updating the default layout and introducing an alternative layout; adding UI shortcuts to split and collapse panels.


Custom themes for the cloud editor

This one was on top of our to-do list for a while. Now, you can change the theme in our cloud editor to a brand-new light theme or pick from a selection of other themes, including some GitHub defaults and some other crowd favorites like Poimandres, Vesper, and Dracula.
