OpenAsar is an open-source replacement for Discord desktop's app.asar file that improves performance and startup speed.
The tool addresses the overhead of Discord's default application archive by providing a lightweight alternative that achieves approximately twice as fast startup times, with experimental configurations potentially reaching four times faster. It also enhances perceived responsiveness during normal use such as scrolling and channel switching. The approach works by replacing the single app.asar file with OpenAsar's optimized version, making installation and removal straightforward.
Developers and Discord users frustrated with startup lag or general client sluggishness should consider this tool. It suits anyone running Discord desktop who wants measurable performance gains without complex setup. The project includes configurable options for both Discord and OpenAsar-specific enhancements, accessible through a settings panel. It also removes Discord's built-in crash and error tracking within the asar itself, which appeals to privacy-conscious users. The installation is genuinely drop-in: replace one file and restart.
The project maintains active development with automated nightly builds. Work is distributed across multiple areas including performance optimization, configuration systems, and splash screen theming support. The codebase shows ongoing refinement of the core replacement logic alongside feature additions for customization.
