LibreTranslate

A free and open source machine translation API that runs entirely on your own server. No Google, no Azure — just open source Argos Translate under the hood.

What You Can Do After Deployment

1. Open the web UI — translate text between 30+ languages directly in the browser
2. Use the REST API — integrate translation into your apps via /translate endpoint
3. Auto-detect languages — the /detect endpoint identifies the source language
4. Add more languages — install additional language packs through the settings
5. Set API keys — optionally restrict access with API key management
