Whatlang is a lightweight Rust library for detecting the natural language of a text, supporting 70 languages plus script recognition. It is fast, pure Rust, and provides confidence and reliability information.

Use cases

• detect the language of a text in rust
• identify which language a user query is written in
• detect script like latin or cyrillic from text
• add language recognition to a search engine
• classify text by language before routing to translation
• filter out texts not in a supported language

When to choose

• you need fast, lightweight language detection in a Rust project
• you need both language and script identification
• you want a pure-Rust dependency with no ML runtime
• you need confidence/reliability scores for detection results

When to avoid

• you need detection for languages outside the 70 supported ones
• you need state-of-the-art accuracy on short or mixed-language texts
• your project is not in Rust and no port is available
