How to Install LibreTranslate on Your Synology NAS

How to Install LibreTranslate on Your Synology NAS

LibreTranslate is a free and Open Source Machine Translation API, entirely self-hosted. Unlike other APIs, it doesn’t rely on proprietary providers such as Google or Azure to perform translations. Instead, its translation engine is powered by the open source Argos Translate library. In this step by step guide I will show you how to install LibreTranslate on your Synology NAS using Docker & Portainer.

💡Note: This guide works perfectly with the latest LibreTranslate v1.5.6 release.
