Install in one command

Both scripts fetch the latest release from GitHub and set Xeonstrap up for you.

Windows 10 and above

PowerShell 5.1 or newer

irm https://xeonstrapp.pages.dev/quick-install | iex

The script downloads Xeonstrap.exe from the latest release and starts the setup. Prefer it manually? Grab the .exe and run it.

Linux and macOS

AppImage on Linux, disk image on macOS

curl -fsSL https://xeonstrapp.pages.dev/install.sh | sh

User-level install: nothing is written outside your home directory. Remove it later with --uninstall.

Shortcuts: /latest opens the newest release, /discord opens the community server, /news returns the in-app news feed as JSON.

Android restricts access to Roblox's files. Xeonstrap uses Shizuku, ADB or root to apply your FastFlags — see the setup guide.

Everything in one place

One app for the settings that Roblox never gives you. Open the menu above to see each one.

FastFlags, done right

A settings panel for the flags you actually use, plus a full JSON editor with an allowlist so you can see what changed.

Deployment control

Choose what happens on launch, keep caches clean, and control CPU and memory use while Roblox runs.

Appearance

Accent colour, background image, window roundness, snow, custom themes and a bootstrapper you can restyle.

Integrations

Activity tracking, server location, friend notifications and a Discord Rich Presence you can shape yourself.

Mods and files

Manage file mods for the client, browse community mods and explore the files in your Roblox install.

Linux through Sober

On Linux and NixOS, Xeonstrap manages Sober through Flatpak and applies your settings around it.

Manager and classic clients

Keep several installs side by side, update them, and launch classic clients straight from the app.

Extensions

Add community extensions to Xeonstrap, or read the source and write your own checks.

Xeonstrap is not an exploit. It does not inject cheats, exploit Roblox or bypass its security — it only manages launching and configuration. Multi-instance launching was removed in version 1.1.2.3 and will not come back.

Frequently asked questions

Can Xeonstrap get me banned?

No. Xeonstrap does not inject cheats, exploit Roblox or bypass its security. It only manages launching and configuration, so you are running the same client Roblox ships.

My antivirus flags Xeonstrap. Is it a virus?

That is a false positive caused by Windows and how it treats unsigned applications. The whole source is public, so you can read and build it yourself.

Which platforms are supported?

Windows 10 and above, macOS on Apple silicon and Intel, Linux through Sober (glibc and musl, x64 and ARM64) and Android 7 and above.

Can I run several Roblox clients at once?

No. Multi-instance launching was removed in version 1.1.2.3 and will not be added back.

Is macOS going to complain about the app?

The macOS build is not notarized by Apple, so Gatekeeper asks once. Open the app from your Applications folder with a right click and then Open, or clear the quarantine flag yourself.

How do I remove Xeonstrap?

On Windows, uninstall it from Apps. On Linux and macOS, run the installer with --uninstall, for example curl -fsSL https://xeonstrapp.pages.dev/install.sh | sh -s -- --uninstall.

Who makes Xeonstrap?

Xeonstrap is maintained by the Xeon Corporation Official team, and it is built on Bloxstrap by pizzaboxer. The Bloxstrap and Fishstrap notices stay in the package.
