What an executor is
An executor is a program that injects into a running game and executes custom code inside it. On Roblox that means Lua: you load a script, the executor runs it in the game process, and whatever that script does happens. The important part is that an executor is a script runner, not a cheat. It ships no aimbot and no ESP of its own. It gives you an environment, and someone else's script provides the features.
That is why executors and scripts are sold as separate products. You buy Wave or Potassium to execute, then load a hub like the ones covered in our Steal A Brainrot script guide to actually do something in a specific game. How many of those scripts run without errors comes down to the executor's sUNC score, the single most useful spec on any executor listing and the subject of our sUNC and UNC explainer.
Prices sit at the low end of the market because competition is fierce. Wave sells a 1 Day key at $2.47 and a 7 Day at $5.97, Real starts at $2.99 for 7 days, and lifetime options run $14.97 on Cosmic or $22.97 on Potassium. Every current option and its live update state sits on the Roblox executors hub.
What an external is
An external never touches the game process. It runs as a separate program that reads game memory from outside and acts on what it finds, drawing an overlay or nudging your mouse. Nothing is injected, which is exactly why externals like Matcha tend to survive detection waves that take injected executors offline for days at a time.
The trade-off is that you get features, not freedom. An external ships a fixed toolkit, typically aim assist, silent aim, ESP and movement options, and you cannot extend it by loading someone else's script. If your goal is running public scripts, an external is the wrong purchase no matter how quiet it stays.
Externals are also the only route on some platforms. Socrate at $5.99 lifetime is the one genuine macOS option for Roblox, because Mac has no real executor scene, which our Mac executor guide goes into. On Windows Roblox, Matcha is $9.99 lifetime and Severe is $19.97 lifetime. In CS2, Pellix starts at $1 for a day and Predator CS2 at $1.49.
What an internal is
An internal is injected into the game process like an executor, but instead of running your code it is the cheat. The aimbot, the visuals, the exploits, all of it ships inside the injected module and runs with full access to the game's memory and functions. That access is why internals have the deepest feature sets in any shooter: prediction, anti-aim, backtracking and similar tricks an external cannot reach reliably.
The cost is exposure. Injected code is precisely what modern anticheats are built to find, so internal providers compete on update speed, staggered rollouts and loader hygiene rather than on promises. When a game ships a big anticheat update, internals are usually the first category to go dark and the last to come back.
In CS2 the internals we track are Nixware from $1.97 for a day and Fecurity CS2 from $3.49 for a day, both listed on the CS2 cheats hub and ranked in our best CS2 cheats roundup. In FiveM, Lumia is $22.99 for 30 days or $34.99 lifetime.
Executor vs external vs internal at a glance
One table, four product types, because script hubs get mixed into this conversation constantly and they are not a fourth kind of software so much as content that needs an executor to run.
| Type | Where the code runs | What you get | Example and price from |
|---|---|---|---|
| Executor | Injected into the game process | Runs any script you load, no built-in cheat features | Wave from $2.47 for 1 day |
| External | Outside the process, reads memory | Fixed toolkit: aim assist, ESP, visuals | Matcha at $9.99 lifetime |
| Internal | Injected into the game process | Purpose-built cheat with the deepest feature set | Nixware from $1.97 for 1 day |
| Script hub | Inside your executor, not the game | Ready-made scripts, useless without an executor | Runs on any sUNC executor, see Roblox executors |
Which type should you buy?
Work through this in order. Most bad purchases in this market come from picking a product before picking a type.
- 1Start with the game. Roblox is an executor and external market. CS2, FiveM, Fortnite and Call of Duty are external and internal markets with essentially no executor scene. Open the right hub first: Roblox, CS2, FiveM, Fortnite, Call of Duty or Marvel Rivals.
- 2Decide whether you need to run other people's scripts. If the answer is yes, only an executor will do, and no external will ever substitute for one.
- 3Set your risk line honestly. If the account holds anything you would miss, lean external and script on an alt anyway. Our ban risk guide covers what actually triggers action.
- 4Check live update status on the status page before you spend anything. A detected or outdated product is worthless today regardless of its type.
- 5Buy the shortest plan available first. A $2.47 day key or a $1 day key tells you more than an hour of reading, and weekly vs lifetime covers when to commit to a one-time payment.
- 6Compare sellers before checkout on the price comparison. The key is identical whoever you buy from, only the number changes.
Is an external actually safer than an internal?
Structurally, yes, and it is worth being precise about why. An anticheat hunting injected modules, hooked functions or tampered memory has a large and obvious surface to scan on an internal or an executor, and very little to scan on an external sitting in its own process. That difference is real and it is why externals historically ride out detection waves that flatten injected tools.
But safer is not safe, and nobody should sell you otherwise. Externals still read game memory, which some anticheats catch through handle monitoring, and they still move your mouse in ways behavioural analysis can flag. Reports from other players do not care about your architecture at all. Every category on this site carries a genuine ban risk, which is the honest premise behind our undetected CS2 cheats piece, where the short version is that the word undetected is marketing.
What actually moves the needle more than type is update discipline. A currently updated internal beats a stale external every single time, which is why we track live state on the status page and document our checks on how we test.
How much does each type cost in 2026?
Type does not set the price as neatly as people expect. Entry prices overlap heavily and the biggest spread is between sellers of the identical product, not between categories.
- Executors, cheapest entry: Wave at $2.47 for 1 day, Real at $2.99 for 7 days.
- Executors, lifetime: Cosmic at $14.97 and Potassium at $22.97, compared in weekly vs lifetime executors.
- Externals on Roblox: Socrate at $5.99 lifetime for Mac, Matcha at $9.99 lifetime, Severe at $19.97 lifetime, Serotonin at $9.97 for 30 days.
- Externals in shooters: Pellix from $1 a day, Predator CS2 from $1.49 a day, Scientist External from $4.99 a day.
- Internals: Nixware from $1.97 a day, Fecurity CS2 from $3.49 a day, Lumia at $22.99 for 30 days.
- Same product, different shop: reseller prices move constantly, so check the comparison page before you check out.
Five mistakes people make picking a type
- Buying an external and expecting to load script hub scripts into it. Externals do not run Lua, and no update will change that.
- Buying an executor for a game with no executor scene. CS2, Fortnite and Call of Duty are external and internal markets, full stop.
- Treating external as a synonym for undetected. It means smaller detection surface, not zero, and it does nothing about player reports.
- Ignoring update status because the feature list looked good. Check the status page first, every time, whatever the type.
- Committing to a lifetime key on a type you have never used. A day key on Wave or Pellix costs less than a coffee and answers the question properly.
