About LibreTranslate

LibreTranslate is a free and open source machine translation API that you can host yourself. It translates text between dozens of languages through a simple REST interface, works fully offline once language models are downloaded, and requires no API keys or third-party cloud services. Developers use it to add private, cost-free translation to websites, applications and internal tools.
