LibreTranslate，免费开源机器翻译 API，完全自托管。不依赖 Google等专有提供商来执行翻译，它的翻译引擎由开源的 Argos Translate 库提供支持。本文提供搭建自已的翻译服务器的方法。

官网地址：https://libretranslate.com/
项目地址：LibreTranslate/LibreTranslate

官网直接就可以用。

部署

sudo git clone https://github.com/LibreTranslate/LibreTranslate
cd LibreTranslate
nano docker-compose.yml
sudo docker-compose up -d

docker-compose.yml

services:
  libretranslate:
    container_name: libretranslate
    build:
      context: .
      dockerfile: ./docker/Dockerfile
    restart: unless-stopped
    ports:
      - "5000:5000"
    ## Uncomment this for logging in docker compose logs
    # tty: true
    healthcheck:
      test: ['CMD-SHELL', './venv/bin/python scripts/healthcheck.py']
    environment:
      - LT_LOAD_ONLY=en,zh

此过程需要梯子。
