Our verdict on js-beautify
js-beautify is an open-source code formatter for developers working with JavaScript, JSON, HTML, CSS, SCSS, and SASS. It suits individuals and teams that want one formatter across JavaScript and markup files, with access through a browser interface, Node.js command-line tools, a Python command-line package, and JavaScript or Python library APIs. Its configuration options cover indentation, line wrapping, brace styles, templating behavior, and other formatting rules. Ignore and preserve directives can keep selected code sections unchanged.
The published pricing model is open source, with a free plan and no paid tiers described. That makes js-beautify a practical fit for developers who want a formatter without subscription plans or tier-based feature differences. Configuration can be managed through .jsbeautifyrc and EditorConfig, allowing formatting behavior to be carried into development environments. The tradeoff is that teams seeking a guided, paid workflow with expanded service features may prefer a different category option.
Editor and development-environment coverage is a notable part of the product. Documented integrations include Visual Studio Code, Sublime Text, Vim, Emacs, Komodo IDE, Cloud9, Fiddler, Burp Suite, NetBeans, and Adobe Brackets. The combination of command-line, library, browser, and editor access gives developers several ways to add formatting to existing workflows. However, js-beautify does not provide AI features, and its positioning is focused on beautification rather than a broader development workflow. Choose it for configurable, multi-language formatting across common tools; look elsewhere if AI-assisted formatting or deeper workflow capabilities are priorities.
