CSpell CLI

cspell-cli is the command-line interface for cspell, a robust spelling checker specifically designed for codebases. It provides comprehensive functionality to lint files, check spelling, trace words, and manage dictionaries directly from the terminal. The package is currently on a major version 10.0.0, released in April 2026, and follows a frequent release cadence, often updating in lockstep with new versions of the core cspell library. These updates can sometimes introduce breaking changes. Its key differentiators include extensive configuration options for various file types and languages, seamless integration with pre-commit hooks, and strong support for custom dictionaries, making it an essential tool for maintaining high code quality and consistency across diverse projects.
