• The program makes heavy use of multithreading, and will work best on processors with a decent amount of cores.
• Made using Rust (backend) and Svelte (frontend)
• This is not an Electron app; this is a Tauri app. Big thanks to all the contributors to Tauri for their amazing work on finally killing Electron for good.
• gmpublisher uses the fantastic steamworks-rs library for interfacing with the Steamworks SDK
• The program is only about ~10 MB
