Language detection

lang.detect on https://fittings.sh. One endpoint, deterministic compute.

Detect the language of a text snippet: ISO 639-1 and 639-3 codes, the Unicode script, a confidence score and runner-up candidates. Latin and Cyrillic languages are separated by function-word profile, other scripts by script; answers 'und' rather than guessing when there is no evidence.
