Why Choose Bloxstrap?

Unlock the best Roblox experience with advanced tools, powerful modding, and full control. Bloxstrap makes Roblox safer, smoother, and more fun for everyone.

Game & Server Tracking

Instantly see which Roblox game and server you’re connected to—no more guessing!
Why it matters: Know where you are, what game instance you’re in, and even which region’s server is hosting your session. This helps you avoid lag, troubleshoot connection issues, and play with friends on the same server more easily.
Who uses it? Perfect for competitive players, streamers, and anyone who wants to join or invite friends efficiently.

Multiple Clients

Launch and run several Roblox game windows at the same time—no advanced tricks needed.
Why it matters: Test different games, use multiple accounts, or develop and play simultaneously. Bloxstrap keeps each instance separate and stable, so you can switch tasks or test multiplayer scripts without relaunching Roblox every time.
Who uses it? Essential for developers, QA testers, and players who run alt accounts for trading or item management.

Custom Mods

Personalize Roblox with safe, user-friendly mods—add custom themes, sounds, cursors, or visual improvements.
Why it matters: Mods let you make Roblox feel unique to you, improve accessibility (high-contrast, font changes), and enable cool community-created features. Bloxstrap ensures mods are isolated and easily managed, so you never risk breaking the base game.
Who uses it? Popular among creative players, streamers, and accessibility-focused users.

Discord Rich Presence

Show your current Roblox game, status, and server live on your Discord profile. Friends can see what you’re doing and join with a single click.
Why it matters: No more copying links or game codes—your Discord presence updates in real time, making it easier to connect, play, or spectate with your community. It also displays extra info, such as playtime, session details, and more.
Who uses it? Ideal for friend groups, content creators, and communities that game together.

Region Server Switch

Instantly swap between different Roblox server regions from one place, without logging out or restarting.
Why it matters: Lower your ping by connecting to the server closest to you, or join friends in other regions for special events. Bloxstrap makes region-switching easy—great for international play or when Roblox auto-matches you to a laggy server.
Who uses it? Competitive players, streamers, and anyone playing with friends abroad.

Presets

Save your favorite Roblox settings (graphics, mods, themes, controls) as one-click presets.
Why it matters: Quickly switch between low-latency settings for competitive gaming, high graphics for visuals, or custom setups for different users on the same PC. Never waste time reconfiguring each time you launch.
Who uses it? Gamers with multiple devices or profiles, and families sharing a PC.

FastFlag Tweaks

Access and adjust Roblox’s hidden “FastFlag” developer settings for advanced graphics and performance control.
Why it matters: Unleash hidden features (like enabling/disabling new engine tech), troubleshoot rare bugs, or boost FPS on lower-end hardware. All flags are easily managed with a visual interface—no risky scripting.
Who uses it? Power users, tech enthusiasts, and developers wanting to experiment with Roblox’s internal options.

Safe & Open Source

100% open-source code, reviewed by the community and security researchers—no hidden spyware or unwanted extras.
Why it matters: You (and your parents!) can always see exactly what Bloxstrap does. It’s trusted by developers and safe for kids, schools, and privacy-conscious users.
Who uses it? Security-focused players, parents, and educators.

Advanced Customization

Unlock extra settings: UI tweaks, scripting hooks, launch options, and more for power users.
