Our Analysis
If you write JavaScript, TypeScript, CSS, HTML, JSON, or Markdown and your team argues about code formatting — tabs vs spaces, semicolons, line length — Prettier ends the debate by formatting everything automatically. It's opinionated on purpose: fewer config options means everyone's code looks the same. 51.7K stars, MIT license, JavaScript. The most widely adopted code formatter in the JS ecosystem. Supports JS, TS, JSX, CSS, SCSS, Less, HTML, Vue, Angular, GraphQL, Markdown, YAML, and more. Integrates with every editor, runs in CI, and has plugins for additional languages. Fully free. No paid tier, no premium plugins, no hosted service. Every language, every integration, every feature — $0. Every JavaScript/TypeScript team should use this. That's not a suggestion, it's the industry default at this point. Solo to enterprise: install it, add it to your editor's format-on-save, add it to CI. Done. The catch: "opinionated" means you don't get to customize much. If you hate Prettier's formatting choices (and some people really do), your options are limited to a handful of config flags. It also doesn't lint — it formats. You still need ESLint for catching actual bugs. And occasionally a new Prettier version reformats your entire codebase, creating massive diffs that pollute git history.
