CSharpier vs Prettier

CSharpier is a free, open-source formatter for C# and XML. It parses source files and reprints them using its own formatting rules, with only a few basic options rather than a broad set of style switches. The homepage states support through C# version 14. Configuration can be kept in .csharpierrc JSON or YAML files or in .editorconfig, covering print width, tabs, indentation, and line endings. CSharpier runs as a .NET tool, installed for one project or globally, and CSharpier.Core provides a NuGet API for formatting from code. It can check files and returns a failing exit code by default when formatting is incorrect. Automation options include pre-commit hooks, MSBuild builds, and CI/CD workflows. Integrations are listed for Visual Studio 2022 and 2019, Visual Studio Code, Rider, Neovim, Emacs, and Zed. It runs on Windows, macOS, and Linux. Code that cannot compile produces error diagnostics instead of being formatted.

Prettier is an open-source code formatter that parses source files and prints them in a consistent style while accounting for line length. Its built-in languages include JavaScript, JSX, Angular, Vue, Flow, TypeScript, CSS, Less, SCSS, HTML, JSON, GraphQL, Markdown, YAML, LWC, and MJML. The command-line interface can write formatted files with --write or check formatting with --check in continuous integration. Listed editor integrations include VS Code, Emacs, Vim, Helix, Sublime Text, JetBrains IDEs, Visual Studio, and Espresso; formatting can run from a shortcut or on save. Prettier has configuration options but keeps them limited. Plugins can add languages and formatting rules, and languages outside the built-in set require a plugin. For ESLint integration, the installation guidance recommends eslint-config-prettier to disable rules that are unnecessary or may conflict. Prettier supports browser and JavaScript API use, along with Linux, macOS, and Windows. The listed plan is free. Commercial support and maintenance are available through the Tidelift Subscription.
