Froststrap

Froststrap is an open-source Roblox bootstrapper and launcher forked from Fishstrap and Bloxstrap. It focuses on performance, customization, launcher control, and quality-of-life features for Roblox users. The project includes tools for managing FastFlags, Roblox update channels, process priority, multi-instance launching, regional server joining, and account handling. It also adds visual customization through themes, fonts, backgrounds, Aero, Acrylic, and Mica-style window effects. Froststrap includes mod support, community mod downloads, cursor customization, death sound changes, font replacement, and Roblox Studio Rich Presence features. It is mainly useful for Roblox players who want a more configurable launcher than the default Roblox bootstrapper.
