Synchronized video viewing with chat and other features. Lightweight modern implementation and very easy way to run locally.

Default channel example: https://synctube.onrender.com/

New features

• Reworked layout and theme
• Multi-Language support
• Hotkeys (Alt-P for global play/pause, etc)
• Mobile view with page fullscreen
• Way to play local videos for network users (without NAT loopback feature)
• Playback rate synchronization (with leader)
• /30, /-21, etc to rewind video playback in seconds
• Links mask: foo.com/bar${1-4}.mp4 to add multiple items
• Override every front-end file you want (user/res folder)
• Native mobile client

Supported players

• Youtube (videos, shorts, streams and playlists)
• Raw mp4 videos and m3u8 playlists (or any other media format supported in browser)
• Iframes (without sync)

Setup

• Open 4200 port in your router settings (port is customizable)
• npm install ws in this project folder (NodeJS required)
• Run node build/server.js
• Open showed "Local" link for yourself and send "Global" link to friends

Setup (Docker)

• As alternative, you can install Docker and run:
• docker build -t synctube .
• docker run --rm -it -p 4200:4200 -v ${PWD}/user:/usr/src/app/user synctube
• (Docker container hides real local/global ips, so you need to checkout it manually)

Configuration

It's just works, but you can also check user/ folder for server settings and additional customization.

Plugins

• octosubs - ASS/SSA subtitles support
• qswitcher - raw video quality switcher

How to use

• Login with any nickname
• Add your video url with "plus" button below (youtube or direct link to mp4 for example)
• Now it plays and syncs for all page users, well done
• You can click "leader" button to get access to global video controls (play/pause, time setting, playback speed)
• If you want to restrict permissions or add admins/emotes, see Configuration above

Intergations

Heroku:

• Create app and commit repo to get build
• Remove user/ folder from .gitignore and commit it to change default configuration
• Add APP_URL config var with your-app-link.herokuapp.com value to prevent sleeping when clients online

Development

• Install Haxe 4.3, VSCode and Haxe extension
• haxelib install all to install extern libs
• If you skipped Setup section before: npm ci
• Open project in VSCode and press F5 for client+server build and run
