Python bindings for LibreTranslate API
Decision gist · record as of 2026-08-14
Yes, if you are already using LibreTranslate and want a simple Python client. The package is permissively licensed, has no dependencies, and installs cleanly. However, verify that it works with your target LibreTranslate version before production use, given the 850-day gap since the last release. For new projects, consider whether calling the LibreTranslate API directly via requests or urllib is simpler than adding a dependency.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires a running LibreTranslate API endpoint (either self-hosted or a public mirror); the package itself is a client library and does not provide translation services.
- Low friction install with no runtime dependencies.
- Last release was in April 2024 and the repository remains active, though the package is aging—no updates in over 850 days.

What it is and what it does
LibreTranslate-py is a lightweight Python wrapper around the LibreTranslate API, a free and open-source translation service. It handles the HTTP communication with a LibreTranslate endpoint and exposes three main operations: translating text between language pairs, detecting the language of input text, and retrieving the list of supported languages. The package uses only Python standard library (urllib and json), so it has zero runtime dependencies and installs quickly.
You point it at a LibreTranslate endpoint—either a public mirror or a self-hosted instance—and call methods to translate, detect, or list languages. It's useful when you want programmatic access to LibreTranslate without building HTTP requests manually. The package is stable and permissively licensed, but has not been updated in over 850 days, so compatibility with the latest LibreTranslate API versions should be verified before relying on it in production.
Use it for
- Translate user-submitted text in a web application by calling a LibreTranslate mirror without managing HTTP requests directly.
- Detect the language of incoming messages to route them to language-specific processing pipelines.
- Query available languages from a LibreTranslate endpoint to populate UI dropdowns or validate language codes.
- Build a simple CLI tool that wraps LibreTranslate for batch text translation tasks.
