Open Source

We at the Guardian try to be as open and transparent as possible. That means developing in public repositories where anyone can see our work. You can explore our source code on GitHub.

What we work with

Languages

• Scala
• TypeScript
• Kotlin
• Swift
• Python

Frameworks

• React
• Preact
• Play
• Astro (which we use for this very site!)

Tools

• Storybook
• Elasticsearch

There are plenty more where these came from, but they are good starting points. And if you want to see our code in action…
