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)

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)
