OpenAsar

An experimental open-source alternative of Discord desktop's app.asar

Features

🚀 Startup Speed: ~2x faster startup times (up to ~4x with experimental config)
📈 Performance: OpenAsar can make your client feel snappier (scrolling, switching channels, etc)
🖌️ Splash Theming: Easy theming for your splash which works with most themes for any client mod
🔌 Hotpluggable: Replace one file and it's installed, that's it (same with uninstall)
⚙️ Configurable: Adds many config options for Discord and OpenAsar enhancements (see config section)
🪶 Lightweight: <2% of Discord's original size (9mb -> ~150kb)
🛡️ No Tracking: Removes Discord's built-in tracking for crashes and errors in the asar (not app itself)

See FAQ for more details

Install Guide

Config

You can configure OpenAsar via settings.json (found in your Discord app data / user data), under a openasar object. Keep in mind most options are defaults for good reason.

OpenAsar Options

quickstart (bool, default false) - whether to use Quickstart (experimental)
themeSync (bool, default true) - syncs your modded client's theme with splash theming
autoupdate (bool, default true) - whether to autoupdate OpenAsar after Discord startup
updatePrompt (bool, default false) - whether to show update prompt after updating OpenAsar
splashText (bool, default true) - whether to show bottom right version info text in splash
ssoeAllowlist (bool, default true) - whether to use safer custom method of opening external urls (true) or normal Discord's method (false)

Extra Discord Options

multiInstance (bool, default false) - whether to enable multi-instance
skipStartupUpdateChecks (bool, default false) - skips startup update checking (Linux-only)

An example of a settings.json with OpenAsar config:

{
  "BACKGROUND_COLOR": "#202225",
  "IS_MAXIMIZED": false,
  "IS_MINIMIZED": false,
  "WINDOW_BOUNDS": {
    "x": 801,
    "y": 22,
    "width": 797,
    "height": 876
  },
  "MINIMIZE_TO_TRAY": false,
  "OPEN_ON_STARTUP": false,
  "openasar": {
    "quickstart": true
  }
}

Additionally there are some environmental variables you can use:

OPENASAR_QUICKSTART (bool, default false) - same as quickstart config option
OPENASAR_NOSTART (bool, default false) - if enabled halts starting after splash loads (for splash testing)
