GritQL is a declarative query language and Rust-based CLI for searching, linting, and rewriting source code using pattern matching over ASTs. It supports many target languages (JavaScript/TypeScript, Python, Java, Terraform, Rust, Go, SQL, and more) and includes auto-fix, custom lint enforcement, and a shareable pattern library.

Use cases

• find all console.log calls in a codebase
• rewrite console.log to winston.log across a repo
• migrate React class components to hooks
• convert Cypress tests to Playwright
• enforce team-specific lint rules in CI
• automate large-scale API migrations
• remove imports from a specific package

When to choose

• you need to search or refactor code across millions of lines
• you want codemods without learning each language's AST APIs
• you need custom lint rules with auto-fix in CI
• you want reusable, shareable code search patterns

When to avoid

• you only need simple regex find-and-replace
• your target language is not among the supported tree-sitter grammars
• you need a GUI-based refactoring tool
