Madium Executor (2026): Free, Working — and the Key-System Dispute

Quick Answer (If You’re in a Hurry): Madium Executor is a free Windows script executor for Roblox, and the live status tracker says it is working right now on version 2.9.0, checked November 11, 2026, with 100% sUNC and 98% UNC. Here is the problem: the same tracker says Madium runs a key system, while nearly every other page calls it keyless. The tracker also flags it as detected, last banwave May 26. There is no verified Madium file on this site — so this page has no download button. But honestly? Read the full breakdown before you download anything.

I have tested a lot of executors on real devices, and Madium is the one where the sources fight each other the hardest. The name is new, the pages all disagree — not about small details, but about the version number, the key system, the platforms, and whether Roblox has flagged it. The pitch underneath the noise is simple: a free Windows executor with top compatibility scores, from a 2026 newcomer that rose fast. That pitch is mostly true. The part nobody tells you: the sources cannot even agree on whether you need a key to open it.

One thing before anything else: nobody on this site has run Madium. I have not installed it, and I am not going to pretend I have. Everything in this guide comes from sources I read on November 12, 2026 — the live status tracker, the comparison pages, the sites that present themselves as Madium’s home, and the security scans of the domains that offer it. Where the sources disagree, I show you both sides. No sponsored rankings, no affiliate bias. Just what actually happened, and what I could not confirm.

1. What Is Madium Executor?

Madium Executor is a free Windows script executor for Roblox: a tool that injects into the Roblox client and runs Lua scripts, the same job Delta and KRNL do. You open Madium, attach it to a running Roblox game, and run a script inside the game. What makes Madium different is the combination: free, Windows-only, top compatibility scores, and a name that appeared in 2026 and rose fast.

Madium scores near the top of the compatibility tests: 100% on sUNC and 98% on UNC, according to the ZekeHub status page I read on November 12, 2026. Those numbers matter, but only for what they measure. UNC and sUNC are compatibility ratings, not safety scores: they tell you scripts will run without errors, nothing more.

The tracker lists Madium as a free key-system executor on Windows, version 2.9.0, by a developer it names as Olemad. The comparison pages agree on the shape — free, Windows, script hub, six themes — but call it keyless, and list 96% UNC instead of 98%. That split is the whole story of this guide.

The tracker lists the same capabilities as for the other serious executors: a decompiler, multi-inject, a client mod bypass, RakNet, and the key system. ZekeHub says Madium runs most of its script across 61+ games, at 70% compatibility — the core features work, a few advanced ones may not. That 70% is the honest number: a near-perfect compatibility score with a partial script run means some scripts will still fail.

2. Which “Madium” Is This? The Name and Domain Problem

Search for Madium and you will find at least four different sites presenting themselves as its home. The first, madium.org, calls itself the only official domain. It lists version 1.7.3, released October 21, 2026, free and keyless, on four platforms — Windows, macOS, Android, and iOS — and names a developer called pkopevs. The second, madium.com.de, is a fan-style site from January 2026, updated in April. It lists version 3.4.1 on the same four platforms, and calls Madium undetected.

The third is madium.net, a download site flagged in 1 out of 92 engines on a November 6, 2026 scan, first seen September 5, 2026. That is a caution signal, not a verdict — but a flagged download page on a two-month-old domain is not a source you trust with your PC.

The fourth is a page on itch.io, which describes Madium as a keyless Windows-only tool for Windows 10 and 11, and cites a 96% UNC figure from ranking pages. It names no version, no developer, and no official domain. The live tracker itself names no official domain either. So here is the honest position: no independent source I read confirms which domain, if any, is Madium’s real home.

Both sites that claim to be Madium’s home tell readers to weaken their own protection instead of verifying the file. Do not do that, and do not trust a page that tells you to. Weakening the protection that watches for malicious files is not a setup step — it is the fastest way to let a bad file run free on your PC. Keep your antivirus and Windows Defender protection on.

One real user report: a MalwareTips thread from October 2026 describes a user whose Madium download was flagged four times by antivirus software. The advice given there was blunt: do not complete the installation, delete the file, and run a full Defender scan. Four flags do not prove a file is malware — executors get flagged because they inject into another program — but four flags on an unsigned installer from an unconfirmed domain are not a reason to push through either.

One more honest note, about the site that claims to be official. Its own page claims a 4.83 out of 5 rating from 973 reviews, and a clean scan with zero engines flagging it. Neither number appears anywhere else I could check, and the page shows no verifiable report behind the scan claim. I am not using either number as a fact: a rating nobody else can verify is a slogan, not evidence.

3. Price: Free — and the Key Question

Madium is free. Every source I read agrees on that much: the tracker, the comparison pages, the fan sites, and the site that claims to be official. No weekly fee, no monthly fee, no paid tier in any source. The site that claims to be official says it has no premium tier, and that anyone selling a paid version of Madium is scamming you. That warning matches every other source: Madium costs nothing, so nobody should be charging you for it.

The real question is not the price. It is the key. The live tracker says Madium runs a key system: you complete a short link or ad flow to get a session key before injecting. Nearly every other page says the opposite: keyless, no key system, no surveys, no waiting rooms. The comparison page, the itch.io page, the fan site, and the site that claims to be official all say keyless.

Here is why I follow the tracker anyway. It is the only source with a dated check behind its claim — version 2.9.0, last checked November 11, 2026 — and it refreshes its status feed every few minutes. The keyless pages give no check date, and several contradict the tracker on the version number too. A key system is also the normal way a free executor pays for itself. But I will not pretend this is settled: if you open Madium and it asks for a key, that matches the tracker. If it opens straight into the editor with no key, that matches the fan pages — and the build you have is not the build the tracker checked.

Here is the part nobody tells you: the key question is the price, even when the price is zero. If the tracker is right, you pay with your time before every session. If the fan pages are right, you pay nothing at all. Either way, never pay for a Madium key, license, or premium build — no source lists a price for one, because no such product exists.

4. Is Madium Working Right Now?

Yes, according to the live tracker — and this is the freshest fact on this page. The ZekeHub Madium status page, last checked November 11, 2026, lists Madium as Working on version 2.9.0, built for the current Roblox release. A second listing page agrees: updated, free, and keyless, on version 2.8.4 — one build behind the tracker, or one build counted differently.

But read the version numbers, not just the verdict. The site that claims to be official lists version 1.7.3, released October 21, 2026. The fan site lists 3.4.1. A directory page lists 1.5.4. Four version numbers for the same tool, all read on the same day. Only the tracker gives a number with a check date behind it: 2.9.0, checked November 11, 2026. ZekeHub adds: Madium is built for Roblox version-4ea8e85481e34f46. If your Roblox has already updated past that build, Madium stops working until Madium updates too.

But read the date, not just the verdict. Checked November 11, 2026, and Roblox ships a new client roughly every week. A “Working” verdict from that check is a fact about that build, not a promise about tomorrow’s. Check the live status yourself before you download anything.

5. Is Madium Detected?

Yes — flagged as detected, right now, by the same live feed. WEAO currently flags Madium as detected, and ZekeHub states it plainly: accounts using it are at risk in banwaves. The last banwave was May 26, and a second listing page agrees. Working and detected are not opposites: an executor can run scripts perfectly and still be flagged, because detection is about whether Roblox’s systems have marked the tool.

ZekeHub adds: Madium bypasses client modification bans, but can still be hit by banwaves — a sweep that hits many accounts at once. Your account is not banned the moment you inject. It is at risk when the next sweep comes.

Here is where the fan pages fail you. The fan site calls Madium undetected. The site that claims to be official tells readers they can run it on their main account without issues. Neither matches the live feed, which says detected with a dated banwave behind it. A marketing page is not a status report. No executor guarantees 100% ban safety. Test on an alternate account, use private or VIP servers, and never run a file you have not verified first.

One gap to name honestly: the tracker gives the banwave as May 26, with no year attached, and I am not going to add one. Detected with a May 26 banwave still means detected.

6. Madium Executor Features, Honestly

Every feature below comes from the tracker listings, the comparison pages, or the sites that present themselves as Madium’s home, read on November 12, 2026. I have not tested any of them myself.

100% sUNC, 98% UNC. ZekeHub lists 100% on sUNC and 98% on UNC, and a second listing page lists the same pair. The comparison page and the directory page list 96% UNC instead. The 96% figure is the one this site’s own audit recorded in October; the tracker’s 98% is fresher, checked November 6. Remember what the numbers measure: compatibility, not safety.

Decompiler, multi-inject, client mod bypass, RakNet. The tracker lists the same capabilities it lists for the other serious executors. A decompiler turns compiled script bytecode back into readable Luau — a real developer tool, and the feature most likely to be oversold, because a decompiler shows you what a script does, it does not make it safe. Multi-inject runs scripts across more than one game instance at once. All four are tracker claims, not things I tested.

70% compatible across 61+ games — the number with a catch. ZekeHub says Madium runs most of its script across 61+ games. The core features work, a few advanced ones may not. It tells you plainly that some scripts will not run fully. Read it next to the 100% sUNC score: the two numbers measure different things, and both are true at the same time.

Built-in script hub, six themes, auto attach. The comparison page lists a built-in script hub and six built-in themes. A directory page adds auto attach — the client connects when Roblox is ready — custom color themes, and support for Infinite Yield, the well-known admin command script. Those are claimed functions, not guarantees.

What I am not listing as features. The fan site claims Madium is undetected. The site that claims to be official claims four platform builds, a clean scan with zero engines flagging it, and a 4.83 out of 5 rating from 973 reviews. None of those come with a version, a date, or a test I can verify. A feature without a source is a slogan. Every source agrees Madium is free, and the live tracker says it works right now. Everything past that is a claim with a question mark on it.

7. Requirements and Platforms

Madium runs on Windows. That is what the live tracker says, and the directory page and the itch.io page agree: Windows 10 and 11 on desktop. The tracker lists no macOS, mobile, or Linux version. If a page offers you Madium for Android or iOS, it is not describing the Madium the tracker describes. No source states a minimum Windows version, and I am not going to invent one.

The shape of the requirement is a Windows PC, the Roblox client installed, and a Madium build that matches your Roblox version: 2.9.0 is built for Roblox version-4ea8e85481e34f46. The key is part of the requirement if the tracker is right. If the fan pages are right, there is no key at all — but you cannot know which is true until you open the build you downloaded, which is why the version check in the next section matters more than any promise on a landing page.

The site that claims to be official lists Windows, macOS, Android, and iOS builds, with file sizes per platform and an iOS sideload note. The fan site lists the same four. The tracker, the directory page, and the itch.io page all say Windows only — three sources against two, and the three include the only one with a dated check. Until a mobile or Mac build is verified by a source with a check date, treat Madium as Windows-only.

8. How to Check Madium Safely Before You Download or Pay

This section has no install steps, and that is deliberate. There is no verified Madium file on this site, no download page, and no VirusTotal scan — because no file has been verified through the freshness pipeline yet. Here is the check-list I would run myself first.

Step 1: Check the live status first. Open the executor status hub on this site, then the ZekeHub Madium page. Confirm the version is still 2.9.0 or newer, the status is still Working, and the Roblox build matches yours. If the status is Down, do not download.

Step 2: Accept that no official domain is confirmed. The tracker names none. One site calls itself the only official domain, two others present themselves as Madium homes, and a fourth hosts a Madium page. If a download page cannot show you a version with a check date behind it, close it.

Step 3: Expect the key question, and do not trust a page that hides it. The tracker lists a key system. Nearly every other page says keyless. If a page offers you Madium with no mention of a key at all, it is describing the fan pages’ version of Madium, not the tracker’s.

Step 4: Confirm the version is 2.9.0. The tracker checked version 2.9.0 on November 11, 2026. If the page you are on lists 1.7.3, 3.4.1, or 1.5.4, it is not the tracker’s build.

Step 5: Use an alternate account, from the first run. No executor guarantees 100% ban safety, and Madium is flagged as detected with a dated banwave. Never test an executor on your main account.

Step 6: Start on a private server. Private or VIP servers significantly reduce the chance of being reported. Do not run scripts on public servers with lots of players.

Step 7: If Windows flags the file, stop and verify — never weaken your protection. Executors often get flagged by antivirus because of how they inject into another program. That flag is information, not an instruction. Keep your antivirus and Windows Defender protection on. A user report from October 2026 describes a Madium download flagged four times — and the advice was to stop, delete the file, and scan. There is no VirusTotal scan for Madium on this site yet.

Step 8: Check the name on the file, not just the name on the page. Madium shares its name across four domains that disagree about the version, the key, and the platforms. Before you run anything, confirm the file’s version is 2.9.0.

9. Madium Executor vs Delta, Arceus X, CodeX, and Fluxus

Here is the comparison against the four executors this site has verified through its own freshness pipeline — Delta, Arceus X, CodeX, and Fluxus — versions as of the November 5, 2026 freshness run. Every cell was checked against this site’s own live guides.

Executor	Price	Platform	Current version	UNC / sUNC	Key system	Best for
Madium	Free (no paid tier in any source)	Windows only	v2.9.0 (checked Nov 11, 2026)	98% UNC / 100% sUNC	Key system (tracker; keyless per fan pages — disputed)	Free PC scripting with top scores
Delta	Free	Android, iOS, macOS, Windows, VNG	v2.745	100% UNC	Key system	Cross-platform, mobile-first
Arceus X Neo	Free	Android, iOS, VNG	v5.1.6.5	98% UNC	Key system	Beginners on mobile
CodeX	Free	Windows (emulator), Android, iOS	v2.731.944	Level 8 (UNC not stated)	24-hour key	Same UI on PC and mobile
Fluxus	Free	Android, Windows, iOS	V701	UNC not stated	24-hour key	Mobile-first scripting

Read the table from the key column first. Madium is the only free Windows-only executor here with a 100% sUNC score and a key system nobody can agree on. Delta posts 100% UNC with a verified file and a VirusTotal scan behind it. Madium posts nearly the same numbers with no verified file and no scan. Start with the Delta guide and the how to use scripts in Roblox guide, and come back to Madium when a file is verified — not before.

10. Who Should Use Madium — and Who Should Not

Use Madium if: you script on a Windows PC; you want a free executor and you accept that the key question is unresolved — you may face a key flow, or you may not; you run scripts that need top compatibility scores; you use an alternate account and private servers; you check the live status every time Roblox updates; and you are comfortable verifying a file yourself, because this site has not verified one.

Do not use Madium if: you play on mobile, Mac, or anything that is not Windows; you want a keyless executor and will not fetch a key if one is asked for; you run scripts on your main account; you need a verified file with a VirusTotal scan before you download anything; or the only Madium you have found is on a domain that cannot show a version with a check date. In that case, use a verified executor from this site.

Here is the part nobody tells you: the best executor is the one that matches how you actually script, not the one with the best numbers on a tracker page. Madium’s numbers are excellent, its price is free, and its live status is fresh. Its detection flag is real, its key system is disputed by almost every page about it, it only runs on Windows, and nobody here has verified its file. If you can hold all of those facts at the same time and still want Madium, you are making an informed choice.

Good luck out there.
