Bloxstrap is a custom game bootstrapper and configuration tool for Roblox. It replaces the standard launcher to enable advanced startup configurations, inject internal engine flags, and manage a specialized installation directory.
The project provides a client mod manager that allows users to override local assets, such as sounds, textures, and fonts, and ensures these customizations persist across game updates. It includes a configuration utility to unlock hidden graphics settings and engine parameters, alongside a server tracker that identifies the geographic location of active game servers and maintains a session history.
Additional capabilities cover social integration through rich presence updates for third-party platforms, performance optimizations like exclusive fullscreen enforcement and resolution downscaling prevention, and the ability to generate server invite deeplinks.
