Zeplin extensions are JavaScript modules that generate code snippets from various design elements. All code snippets you interact with in Zeplin are generated using extensions curated at extensions.zeplin.io.
All the way from a simple extension that counts the characters in a text layer for your copywriter to a full-fledged extension that generates code snippets from layers, colors, and text styles, extensions can examine pretty much all the data you see in Zeplin. All the built-in code snippets in Zeplin are implemented as extensions using the same infrastructure.
Check out the documentation to learn more about extensions' capabilities and how to create your first Zeplin extension. We've also prepared a tutorial to guide you through your first extension: https://github.com/zeplin/zeplin-extension-documentation/blob/master/tutorial.md.
Here are the open-source extensions that can help while building yours:
