Self-host Twitch VOD & live archiver with real-time chat replay and WebUI.

Core Features

  • Real-time chat playback: sync chat with VOD or live stream, rendered as separate video file
  • Automatic channel watching: set watched channels to archive future broadcasts and livestreams with filters
  • Complete management: manage channels, users, archives, playlists, and playback progress via WebUI
  • Friendly file structure: video + JSON chat stored in standard format, viewable without Ganymede
  • Custom processing: FFmpeg post-processing parameters, chat render styles, webhook notifications

What It Can't Do

  • •Large storage required: at least 50GB free; active archiving consumes more. 2. Must have Twitch developer application: register on dev.twitch.tv for Client ID and Secret. 3. Default password security: change admin password immediately after first login. 4. Limited Chinese UI: translation files need manual addition. 5. Docker-only: requires Linux or WSL2; not supported on Windows natively.

Use Cases

  • Twitch streamers or viewers to permanently archive streams with chat interaction
  • Content creators downloading Twitch footage for editing while preserving chat overlay
  • Archiving enthusiasts building a private video library for multiple channels

Detailed Introduction

Ganymede is a self-hosted platform for archiving Twitch VODs (past broadcasts) and live streams, featuring synchronized real-time chat playback. It provides a full WebUI for managing archives, channels, and users, with automatic watching of channels for new content. All files are saved in a standard format (video + JSON chat) so they can be viewed without Ganymede. It includes advanced features like SSO/OAuth authentication, custom FFmpeg parameters for post-processing, webhook notifications, and a recoverable queue system. Built with two Docker containers (server + Postgres), it requires a Linux environment and a Twitch application for API access. The project is actively maintained with regular releases and comprehensive wiki documentation.

Troubleshooting & FAQ (1)

Troubleshooting
How to fix 'unsupported protocol scheme ""' error when running Fetch JWKS task?

The error occurs because the OAUTH_PROVIDER_URL environment variable is empty or missing the protocol scheme. Set OAUTH_PROVIDER_URL to a valid URL starting with http:// or https:// (e.g., https://sso.example.com). Restart the container after updating the variable.
