Why look beyond Prettier
Prettier provides a largely unopinionated approach to code formatting, aiming to eliminate discussions around style by enforcing a consistent output. It excels in JavaScript and TypeScript environments, offering broad integration with development workflows. However, its strength in opinionated formatting can also be a limitation for teams requiring more granular control over specific style rules or those working with languages not natively supported by Prettier. For instance, while Prettier handles formatting, it does not perform static analysis or identify potential code errors, a function typically addressed by linters. Developers might also seek tools that offer a more integrated solution for both formatting and linting, or those specifically tailored to their primary programming language, such as Python or Go, where dedicated formatters are prevalent.
Teams might also look for alternatives when they need to migrate large legacy codebases with established, non-Prettier-compliant formatting conventions, as Prettier's aggressive reformatting can necessitate significant initial changes. Lastly, some projects may prefer a formatter that allows for precise customization of every rule, rather than relying on Prettier's minimal configuration philosophy.
Top alternatives ranked
-
1. ESLint — Pluggable JavaScript linter and formatter
ESLint is a powerful and highly configurable linter for JavaScript and TypeScript. While Prettier focuses solely on code formatting, ESLint provides a broader scope by identifying problematic patterns, enforcing best practices, and ensuring code quality beyond mere style. ESLint can be configured to integrate with Prettier, allowing Prettier to handle formatting while ESLint addresses linting rules. However, ESLint also has its own formatting rules, which can serve as a direct alternative for teams that prefer a single tool for both linting and formatting, or who require more fine-grained control over their formatting rules than Prettier offers. It supports custom rules and plugins, making it adaptable to almost any JavaScript project requirements.
ESLint is best for:
- JavaScript and TypeScript projects requiring extensive code quality checks.
- Teams needing highly customizable linting and formatting rules.
- Integrating formatting with static analysis and error detection.

2. Black — The uncompromising Python code formatter
Black is an opinionated code formatter for Python, designed to be uncompromising in its approach to style. Similar to Prettier, Black aims to eliminate style debates by providing a single, consistent format for Python code. It automatically re-formats code to adhere to the PEP 8 style guide, with some deviations for consistency and readability. Black's philosophy is to be "the uncompromising code formatter," meaning it offers very few configuration options, forcing a highly consistent style. This makes it an excellent alternative for Python projects that value consistency and want to minimize configuration overhead, mirroring Prettier's approach but for the Python ecosystem. Black integrates with various editors and version control systems.
Black is best for:
- Python projects seeking strict, consistent code formatting.
- Teams that prefer minimal configuration for code style.
- Enforcing PEP 8 compliance with additional consistency.

3. GoFmt — Go programming language formatter
GoFmt is the canonical formatter for the Go programming language, built directly into the Go toolchain. Much like Prettier, GoFmt is highly opinionated and provides almost no configuration options, ensuring a single, consistent style across all Go code. Its strict adherence to a predefined style is a core part of the Go language's design philosophy, promoting readability and reducing cognitive load. As an integral part of the Go development experience, GoFmt is automatically invoked by many Go tools and IDEs. For developers working primarily in Go, GoFmt serves as the default and most widely accepted code formatting solution, making it a natural alternative to Prettier in that specific language context.
GoFmt is best for:
- Go programming language projects.
- Enforcing a consistent, unconfigurable code style.
- Integration with the Go toolchain and development environment.

4. Stylelint — A mighty, modern linter that helps you avoid errors and enforce conventions in your styles
Stylelint is a powerful and flexible linter for CSS, SCSS, Less, and other CSS-like languages. While Prettier can format CSS, Stylelint goes further by enforcing coding conventions, catching errors, and promoting best practices within stylesheets. It offers over 170 rules, many with autofix capabilities, allowing for significant customization. For teams working extensively with styling, Stylelint provides a more comprehensive solution than Prettier alone, which primarily focuses on formatting syntax rather than stylistic correctness or error detection. Stylelint can be used alongside Prettier, with Prettier handling basic formatting and Stylelint enforcing more complex style rules and catching potential issues.
Stylelint is best for:
- CSS, SCSS, Less, and similar stylesheet languages.
- Enforcing detailed styling conventions and catching errors in stylesheets.
- Projects requiring highly customizable CSS linting rules.

5. EditorConfig — Maintain consistent coding styles for multiple developers working on the same project
EditorConfig is not a formatter or linter in itself, but rather a file format that helps maintain consistent coding styles for multiple developers working on the same project across different editors and IDEs. It allows defining basic coding styles like indent_style (tabs vs. spaces), indent_size, end_of_line, charset, and trim_trailing_whitespace. While Prettier takes a comprehensive approach to reformatting, EditorConfig addresses foundational aspects of code style that can prevent conflicts and ensure a consistent base. It's often used in conjunction with formatters like Prettier or linters like ESLint, but it can also serve as a minimal, editor-agnostic approach to enforcing basic style rules when a full formatter is not desired or when working with languages without a dedicated formatter.
EditorConfig is best for:
- Establishing basic, cross-editor code style rules.
- Ensuring consistency in indentation, line endings, and whitespace.
- Projects that need a lightweight, editor-agnostic style enforcement.
Learn more on the EditorConfig profile page or access the EditorConfig homepage.

How to pick
Choosing the right code formatting or linting tool depends on your project's specific needs, the languages you're using, and your team's preference for configuration versus opinionated defaults. Consider these factors when making your decision:
- Language Focus:
- If your primary language is JavaScript or TypeScript and you need comprehensive static analysis alongside formatting, ESLint is a strong candidate. It offers extensive rule customization and can even integrate with Prettier for a combined approach.
- For Python projects, Black is the de facto standard, providing an uncompromising, opinionated formatter that virtually eliminates style debates.
- In the Go ecosystem, GoFmt is built directly into the language toolchain and is the universal choice for Go code formatting.
- For styling languages like CSS, SCSS, or Less, Stylelint offers advanced linting and error detection capabilities beyond basic formatting.
- Level of Opinionation vs. Configurability:
- If you prefer a tool that makes most style decisions for you with minimal configuration, mirroring Prettier's philosophy, then Black (for Python) or GoFmt (for Go) are excellent choices within their respective languages.
- If your team requires granular control over every aspect of code style and needs to enforce specific conventions that might deviate from a formatter's defaults, ESLint or Stylelint provide extensive configuration options through custom rules and plugins.
- Scope of Tool: Formatting vs. Linting:
- Are you looking solely for formatting to ensure consistent visual style, or do you also need static analysis to catch potential errors and enforce best practices? Tools like Prettier, Black, and GoFmt are primarily formatters.
- Linters like ESLint and Stylelint offer both formatting capabilities (through autofixable rules) and crucial error detection. You might choose to use a dedicated formatter alongside a linter for a comprehensive solution.
- Cross-Editor Consistency:
- Even with a dedicated formatter, basic settings like indentation can vary between editors. EditorConfig is a valuable complementary tool that establishes fundamental code style settings (like tabs vs. spaces, line endings) that are respected across various IDEs and text editors, ensuring a consistent base for any formatter.
- Integration with Existing Workflows:
- Consider how easily the alternative integrates with your current development environment, CI/CD pipelines, and version control hooks. Most popular tools offer plugins for major editors and CLI interfaces for automation.
