Magika is an AI-powered file content type detection tool that uses a small, highly optimized deep learning model to identify 200+ file types within milliseconds on a single CPU. It is available as a Rust-based CLI, a Python package, and bindings for JavaScript/TypeScript, Rust, and Go.

Use cases

• detect the content type of a file
• identify mime type of uploaded files
• detect file type from bytes instead of extension
• scan directories to classify thousands of files
• route files to security scanners based on content type
• detect file types in the browser or nodejs

When to choose

• you need fast, accurate file type detection beyond simple extension or magic-byte checks
• you need to process large volumes of files at scale
• you need bindings across Python, Rust, JavaScript, or Go
• you need accurate detection of textual content types like source code

When to avoid

• you need to detect obscure file types outside its 200+ supported content types
• you cannot tolerate a small ML model dependency in a minimal environment
• you only need basic magic-number checks that libmagic already covers
