Continuing on last week’s post about RunKit – a Node.js prototyping environment for the browser – here are two interesting tools that make use of RunKit:

• GitBook is a collaborative documentation tool that allows you to create beautiful, version-controlled documentation for your software. It’s used by software components like Redux and it leverages RunKit to embed live, reactive code examples in your documentation.
• Fieldbook is a database creation tool thats touted as “A database with an API – as simple as a spreadsheet“. By employing RunKit Fieldbook lets you try out the API you created right in the browser.
