"Been through four executors this year — Bunni is the first one I stopped noticing. Attach is under a second, the hub covers every game I play, and v4.2.5 fixed the Android stutter from the last patch."

// About
What is Bunni Executor?
A keyless Roblox script executor for Windows, macOS, Android and iOS — 100% UNC, 0.8 s inject, patched within 24 h.
Bunni Executor is a Roblox script executor built for speed and stability: 100% UNC and sUNC coverage, injection in 0.8 seconds on average, and an auto-update that ships within 24 hours of every Roblox patch — 51 updates released in 2026 alone.
No key system, no ads, no surveys. Download in 40 seconds, install in 2 clicks, 84.2 MB on disk. Attach, paste a Pastebin script, press Execute — that is the whole flow.
How Bunni Executor works
An executor is a bridge between a Lua script and the Roblox client. When you press
Attach, Bunni injects a custom Lua environment into the running
game process. That environment exposes the full UNC/sUNC API set —
loadstring, game:HttpGet(),
hookfunctions and more — so scripts can read and modify the game the same way
Roblox's own code does.
Bunni then stays out of your way: the built-in hub indexes 500+ scripts and syncs them daily, the editor runs anything you paste from Pastebin, and the auto-updater pulls a fresh build within 24 hours of each Roblox patch — 6 hours median. You never re-download from scratch and never touch a key system.

// Safety
Is Bunni Executor Safe?
The official Bunni Executor v4.2.5 build is clean: 0 of 72 engines on VirusTotal flag it (scanned Oct 20, 2026). No miners, no data collection, SHA-256 published with every release. Check both independent reports yourself:
How to spot a fake Bunni Executor download
Bunni's name gets used to distribute malware. Five checks before you run any "Bunni" file:
- Domain. The only official source is bunni.icu/download/ — no mirrors, no "bunni-key.com", no .tk/.xyz clones.
- Key pages. Real Bunni is keyless. Any site asking you to "generate a Bunni key" through linkvertise checkpoints is fake by definition.
- File name & size. Official builds ship as Bunni_Executor_v4.2.5.zip, 84.2 MB. A 2 MB ".exe" named Bunni is a stealer.
- Direct messages. Nobody from the team sends installers in DMs. "Early access v5 test build" attachments are always malware.
- Hash. Compare the SHA-256 of your file against the one published with the release notes before running it.

What Players Say
152 ratings · 4.81 average — collected on the download page and in the community chat.
"Runs on my Android phone at 60 FPS with ESP on. No key, no checkpoint mazes — I downloaded it and was executing scripts two minutes later."
"Solid on Windows 11 — injects first try, CPU mode keeps frames stable. Four stars only because the iOS sideload still needs a re-sign every week."
"loadstring and game:HttpGet work out of the box, so my whole Pastebin folder just runs. The editor even flags my typos before Roblox does."
"ESP holds 60 FPS on a mid-range phone since the Low CPU mode landed. Auto-farm ran six hours straight, zero crashes."
"Auto-update pulled the new build seven hours after the Roblox patch — I didn't even notice a version had dropped. On a Mac, that's unheard of."

Upgraded from v4.2.0 — attach feels instant again. If your hub list looks empty after updating, press Sync once, it re-indexes in a second.
PSA for Android users: allow installs from your browser before running the installer, saves you the "App not installed" error. Works great on a Pixel 7.
Been running auto-farm 4–5 hours a day on an alt since v4.1. Zero crashes, zero FPS dips with Low CPU mode on. The 4.81 average is earned.
