| Name | Type | Detection Risk | Notes | |------|------|----------------|-------| | Krnl | Client-side (with server-side scripts via remotes) | High (often patched) | Most popular free executor, but not truly server-side. Requires key system. | | Electron | Client-side | Very high | Decent execution, often flagged as virus (false positive? risky). | | Fluxus | Client-side | High | Old favorite, now outdated for most server-side attempts. | | Oxygen U | Client-side | Extreme | Newer executor, but community reports many malware scans fail. | | Synapse X (cracked) | Client-side | Extreme (ban + malware risk) | Cracks are 99% viruses. Original Synapse is paid and discontinued. |

In the Roblox exploiting community, a "Serverside Executor" is the holy grail. Unlike clientside tools that only affect your local game client, a serverside executor runs scripts directly on Roblox’s servers. This allows you to manipulate the game for everyone in the server—spawning items, giving everyone admin commands, or even crashing the server.
But here is the catch: True, reliable, and free serverside executors are extremely rare. Most are either patched instantly, contain malware, or are paid "backdoor" passes.
