Markdown vs Mustache: What are the differences?
Markdown: Text-to-HTML conversion tool/syntax for web writers, by John Gruber. Markdown is two things: (1) a plain text formatting syntax; and (2) a software tool, written in Perl, that converts the plain text formatting to HTML; Mustache: Logic-less templates. Mustache is a logic-less template syntax. It can be used for HTML, config files, source code - anything. It works by expanding tags in a template using values provided in a hash or object. We call it "logic-less" because there are no if statements, else clauses, or for loops. Instead there are only tags. Some tags are replaced with a value, some nothing, and others a series of values.
Markdown and Mustache are primarily classified as "Languages" and "Templating Languages & Extensions" tools respectively.
"Easy formatting" is the primary reason why developers consider Markdown over the competitors, whereas "Dead simple templating" was stated as the key factor in picking Mustache.
Mustache is an open source tool with 13.1K GitHub stars and 2.3K GitHub forks. Here's a link to Mustache's open source repository on GitHub.
According to the StackShare community, Markdown has a broader approval, being mentioned in 749 company stacks & 702 developers stacks; compared to Mustache, which is listed in 231 company stacks and 18 developer stacks.
