Slate vs zeroheight: What are the differences?

Slate: Beautiful static documentation for your API, inspired by Stripe's and Paypal's API docs. Slate helps you create beautiful API documentation. Think of it as an intelligent, responsive documentation template for your API; zeroheight: UX design docs that stay up-to-date. Document your design system, together. Create beautiful living styleguides and document all your design system resources in one place.

Slate and zeroheight can be categorized as "Documentation as a Service &" tools.

Some of the features offered by Slate are:

• Clean, intuitive design — with Slate, the description of your API is on the left side of your documentation, and all the code examples are on the right side. Inspired by Stripe's and Paypal's API docs. Slate is responsive, so it looks great on tablets, phones, and even print.
• Everything on a single page — gone are the days where your users had to search through a million pages to find what they wanted. Slate puts the entire documentation on a single page. We haven't sacrificed linkability, though. As you scroll, your browser's hash will update to the nearest header, so linking to a particular point in the documentation is still natural and easy.
• Slate is just Markdown — when you write docs with Slate, you're just writing Markdown, which makes it simple to edit and understand. Everything is written in Markdown — even the code samples are just Markdown code blocks!

On the other hand, zeroheight provides the following key features:

• Sync with your favorite design tools
• Add interactive HTML and Storybook code
• Write, embed and organize content
