# Mosaico (Email templates)

> Mosaico is a free, open-source email template collection built with HTML. Mosaico - Responsive Email Template Editor. It has 1,784 GitHub stars and is released under the GPL-3.0 license. A live demo is linked from this page. Start a project with npx degit voidlabs/mosaico or clone the repository.

Mosaico is a JavaScript library (or maybe a single page application) supporting the editing of email templates. The great thing is that Mosaico itself does not define what you can edit or what styles you can change: this is defined by the template. This makes Mosaico very flexible.
