Bunni is a keyless Lua script executor for Roblox that runs on Windows and Android. It reads and executes user-supplied Lua scripts inside the Roblox client, functioning as a script injector without a key system. The tool targets users who want a working setup with minimal configuration on PC or mobile.

The executor centers on Lua script execution with a built-in script editor and console output for reading results and errors. Reported behavior includes fast injection and low crash rates during typical sessions. Keyless operation removes the token or checkpoint step common to many Roblox exploit tools. A minimal interface handles attach and execution controls, and anti-detection methods are listed among its stated functions. Script compatibility is a primary focus, with support for standard Lua scripts sourced from common script libraries.
The script tool supports Windows PC and Android, giving it a multi-platform position across desktop and mobile. Compatibility claims across listings reference high UNC and sUNC coverage, often cited in a 95–99% range, which indicates how many standard functions execute correctly. PC and mobile builds differ in setup: desktop use may require administrator privileges, ZIP extraction, and firewall or antivirus exceptions, while the Android version runs as a packaged mobile client. Actual results depend on the current Roblox version and the specific scripts being run.
Roblox pushes client updates and Byfron-related patches that can break injection until the executor is rebuilt. Listings describe regular updates after Roblox patches to restore a working build. Update cadence and freshness are recurring signals in current 2026 references, though a build marked stable one week may need re-patching after the next Roblox update. Verifying that a download source is current and consistent reduces the chance of using an outdated or non-functional version.
Antivirus software may flag executor downloads as false positives, which is common for this software category and does not confirm the file is safe on its own. Confirm the source is legitimate, compare mirrored listings for consistency, and check that the version matches the current Roblox client before installing.
