ninetymiles/file-bridge repository overview

⁠FileBridge

A DingTalk chat bot that automatically saves photos, videos and files sent in chats to your server.

Company members simply send files to the bot in DingTalk (group chat via @mention, or direct chat) — no VPN or extra apps needed. It runs with a WebSocket stream connection, so no public IP or domain is required.

⁠Features

• Auto-saves photos, videos and files sent to the bot
• Group chat: @ the bot with images; direct chat: all file types
• Duplicate files are detected automatically (SHA-256)
• Media info attached on save (photo time, aperture, shutter, ISO / video resolution, fps)
• Say "重建索引" to clean up stale file records — also runs automatically on startup
• Online/offline notifications to a group or a colleague

⁠Quick Start

docker run -d \
  --restart unless-stopped \
