Our verdict on CSharpier

CSharpier is an open-source formatter for C# and XML source code, aimed at developers and teams working across Windows, macOS, and Linux. It parses source code and reprints it according to its own formatting rules. Teams can install it as a local or global .NET tool, use command-line formatting and format checking, or connect it to supported editors. Its open-source distribution under the MIT License also suits projects that want a formatter without a paid licensing model.

Configuration and workflow controls are a major part of the product. Developers can configure CSharpier through .csharpierrc, YAML, JSON, or .editorconfig files, while .csharpierignore, .gitignore, and ignore comments provide several ways to exclude files or code. Formatting validation is designed to detect syntax-tree changes, which helps teams check formatting without treating the formatter as a simple text replacement. CSharpier.Core also provides programmatic formatting for applications or custom tooling.

Its integration range makes it practical for mixed-editor teams: official integrations and setup guidance cover Visual Studio 2022, Visual Studio 2019, Visual Studio Code, Rider, Neovim, Emacs, and Zed, with format-on-save support available through editor integration. The main trade-off is its focused scope and opinionated rule set: it targets C# and XML rather than multiple programming languages, and its formatting approach is defined by CSharpier rather than extensive style-rule selection. Choose it when a C# team wants consistent formatting across major IDEs and command-line workflows; consider another tool when broader language coverage or AI-assisted features are central requirements.
