Pretty Diff is a language-aware code beautifier and comparison tool written in TypeScript that supports many languages including HTML, JavaScript, TypeScript, CSS, XML, and Java. It can also minify code and perform other formatting-related transformations.

Use cases

• beautify and format html css and javascript code
• compare two versions of code with language-aware diffing
• minify javascript css and markup files
• format typescript and less files consistently
• diff minified code against source code
• clean up inconsistent indentation in xml and markup files

When to choose

• you need a single tool that both formats and diffs code across many languages
• you want language-aware diffs rather than plain line-based diffs
• you need minification alongside beautification in one library
• you work primarily with web languages like html css javascript and typescript

When to avoid

• you need actively maintained tooling with frequent updates and community support
• you prefer modern formatters like prettier with a large plugin ecosystem
• you need formatting for languages outside its supported set
• you require a permissively documented standard license for enterprise compliance
