Gelato removes all the hassle of creating and maintaining technical docs, and makes onboarding developers easy. Gelato doesn't just give you amazing docs. You also get a
full-featured developer portal. Write your docs in Markdown with its live preview editor, use full-screen “zen” mode, include images and more code. Upload or sync with Github, up to you - and if you don't have a definition, just use its reference editor! Make your portal yours with a custom logo, colors, header, footer, and more. Define your API and it'll generate sample code in every language you need. Add more developers on your API with its super easy registration and SSO options.
Gelato was recently acquired by Mashape and is available as an on-premise option as well as a SaaS offering. It is free to use for open-source projects and has an Enterprise edition available for large scale applications.
