What Makes Us Best
We respect the competition — here's an honest look at the top executors of 2026 and why Cosmic still wins.
MacSploit
Great on MacMacSploit is genuinely the best executor for macOS and iOS — native Apple Silicon support, a solid editor, and a huge script cloud. But it's Apple-only, and it still relies on a key/license system. If you're on Windows — which is where 95% of Roblox players are — Cosmic gives you 100% Luau support, a zero-key experience, and weekly Hyperion patches, completely free and forever.
Delta
Great on mobileDelta is a strong multi-platform executor with a polished mobile app and an enormous script hub — there's a reason it's so popular. The catch is the 24-hour key system on mobile, which forces daily Linkvertise-style tasks, and its native PC build has lagged behind the mobile versions. Cosmic skips the key ritual entirely: download, inject, execute. On desktop we're patched weekly with a full Luau VM, so you're never stuck on an outdated build.
Potassium
Strong Windows enginePotassium is a capable Windows executor with a built-in decompiler, multi-instance support, and fast patch turnaround — honestly good engineering. But it uses kernel-level injection, which can force a PC restart after use and carries real stability risk, and it has been flagged in past banwaves. Cosmic uses a safer user-mode stealth driver, ships weekly updates, and stays invisible — no restarts, no BSOD lottery, no banwave roulette.
Xeno
Popular & open-sourceXeno is a popular free, keyless, open-source executor with a clever in-game ImGui menu — great for tinkerers who want to read the source. Its UNC score sits around 88%, there's no official support channel, and the clone-site problem in its ecosystem is genuinely dangerous (several fake domains distribute malware). Cosmic offers 100% Luau compatibility, a proper external editor with a vetted Script Hub, and an official Discord with real human support — without the malware-bait minefield.
Velocity
Clean & keylessVelocity is a clean, keyless Windows executor with a Monaco-based editor and impressively fast updates — respect where it's due. But it's Windows-only with no real mobile path, and its script library is on the smaller side. Cosmic matches its keyless convenience while adding a richer vetted Script Hub, cloud sync, and a true 100% Luau VM — and we're already laying the groundwork for Android in late 2026.
Madium
Promising newcomerMadium is a promising young executor — keyless, ~96% UNC, ambitious cross-platform goals, and a modern UI. It simply isn't battle-tested yet: it's much newer, the community is smaller, and its compatibility still trails a full 100% Luau VM. Cosmic has been running since March 2024 with 1.4M+ users, a 99.8% stability record, and weekly updates you can set your watch by. Experience matters.

Frequently Asked Questions
Quick answers to the questions we hear most.
Is it free to download in 2026?
Yes — 100% free, with no keys, no surveys, no premium tier, no payment of any kind. Download here.
Does it require a key system?
No. Unlike most free Roblox executor tools, this one is fully key-free. Just download, inject, and run.
Is it safe and undetected?
Yes. Every build is scanned on VirusTotal and our domain passes Google Safe Browsing checks — see the safety section. The Hyperion bypass is updated weekly, so the injector stays undetected. AV flags are unavoidable for any executor — see step 1.
What operating systems are supported?
Windows 10 and Windows 11 (64-bit). An Android beta is planned for Q4 2026, with more platforms after that.
How often is it updated?
Weekly updates, typically within hours of any Roblox client patch, so you're never stuck with an outdated executor.
Does it support Luau and major script libraries?
Yes — full Luau VM support, plus Owl Hub, Infinite Yield, Dark Hub, Hydroxide, and most Scriptblox libraries out of the box.
Can I get banned for using a Roblox script executor?
Bans are always possible when modifying any game client. The Hyperion bypass minimizes risk, but for max safety use an alt account, never your main.
Which Roblox games are supported?
Every major experience — Blox Fruits, Pet Simulator 99, Da Hood, Arsenal, MM2, Adopt Me, Brookhaven, Bedwars and thousands more. See the full list here.
Is Cosmic Executor Safe?
Yes — and we can prove it. Every release of Cosmic Executor is scanned before it goes public, and our latest v2.6.2 build is verified clean. The getcosmic.net domain also passes Google Safe Browsing site-status checks, which means no malware, phishing, or deceptive content has ever been detected on it. Both are public tools — you can run your own scan on the downloaded file any time you like.
One honest note: like every script executor, our installer can trigger antivirus false positives. Injectors use the same low-level techniques as some malware, so behavior-based scanners sometimes flag them — not because the file is malicious. If your AV raises an alert, scan the file on VirusTotal first, then follow step 1 of the install guide.
Pros and Cons of Cosmic Executor
We don't sugarcoat. Here's exactly what you get — and what you don't.
Pros

- Full Luau VM — 100% UNC support, runs 99%+ of public scripts without edits
- Built-in vetted Script Hub with cloud sync, auto-update, and one-click execute
Cons
- Windows only for now — no native macOS build yet; Android beta lands in Q4 2026
- Antivirus false positives — you must temporarily disable real-time protection to install
- Ban risk — any executor can get an account banned; we recommend an alt account
- Script Hub is 600+ vetted scripts — smaller than giant auto-curated libraries with thousands
- Requires administrator rights to inject — some restricted or corporate PCs block it
