## What it is
CSpell is a fast, pure-JavaScript spell checker designed specifically for source code, available as a CLI tool, library, VS Code extension, and ESLint plugin. It supports dozens of programming and human languages, custom dictionaries, and configuration via cspell. files.

## Use cases
- spell check my codebase from the command line
- catch typos in documentation and comments in CI
- add a spell checker to my VS Code setup
- lint spelling errors in a monorepo with thousands of files
- add custom project dictionaries for domain-specific terms
- run spell checking in a GitHub Actions pipeline

## When to choose
- you need spell checking tuned for code identifiers and comments
- you want a pure JS tool with no external binaries or web services
- you need CI/CD, editor, and ESLint integration from one tool
- you need custom dictionaries and multi-language support

## Facets
- artifact type: library
- maturity: active
- function: linter, cli, developer-tools
- domain: developer-tools, text-editors, documentation
- platform: cli, cross-platform, editor-plugin
