If you've been hunting for a way to get roblox multiple instances free, you already know how annoying it is when the game closes your first window the second you try to open another one. It's one of those limitations that feels a bit outdated, especially when so many games today encourage you to have alt accounts for trading or grinding. Whether you're trying to farm coins in Pet Simulator 99 or you just want to move items between accounts in Adopt Me, being stuck with one window at a time is a massive bottleneck.
The good news is that the community has been working on workarounds for years. You don't have to pay for some sketchy "premium" tool or jump through impossible hoops. There are several reliable ways to get those extra windows open without spending a dime.
Why the Official Client Blocks Multiple Windows
Before we dive into the "how," it's worth a second to talk about the "why." By default, Roblox uses something called a "singleton mutex." It's basically a little piece of code that tells your computer, "Hey, if there's already a version of me running, don't let another one start."
Roblox does this mostly for stability. Running two or three copies of a 3D game takes a toll on your CPU and RAM. If your computer isn't powerful enough and you accidentally open five tabs, your whole system could freeze. But for those of us with decent gaming rigs—or even just a mid-range laptop—we know we can handle more than one instance.
The Best Way: Bloxstrap
If you ask anyone in the community right now what the best method for roblox multiple instances free is, they're probably going to tell you to download Bloxstrap.
Bloxstrap isn't a "cheat" or a "hack." It's an open-source bootstrapper that replaces the standard Roblox launcher. It gives you a ton of cool features, like choosing your lighting engine or seeing which server location you're actually connected to. But the biggest draw for most people is the built-in multi-instance support.
Setting it up is pretty straightforward. Once you install it, you just go into the Bloxstrap Menu, find the "Roblox Settings" or "Integrations" tab, and look for the option that says "Allow multi-instance launching." You toggle that on, hit save, and you're basically done. From then on, you can just keep clicking "Play" on different accounts from the website or the app, and it will just keep opening new windows instead of closing the old ones. It's honestly the cleanest way to do it because it feels like a native feature.
The Classic Route: Multi-Roblox
Before Bloxstrap became the go-to, everyone used a tiny little program called "Multi-Roblox" or the version hosted on WeAreDevs. It's a very simple tool that specifically targets that "mutex" I mentioned earlier and kills it.
The way it works is a bit different. You usually have to open the Multi-Roblox tool before you open your first game window. Once the tool is running in the background, it sits there and prevents Roblox from realizing that another instance is trying to start.
One thing to keep in mind with this method is that because it's a third-party tool that "hooks" into how Roblox launches, some antivirus software might give you a warning. Usually, it's a false positive, but you should always be careful and make sure you're downloading it from a reputable source. If you're nervous about that, Bloxstrap is definitely the "safer" feeling alternative since it's widely used and open-source on GitHub.
Using Different Platforms
If you don't want to download any extra software at all, you can actually get roblox multiple instances free just by using the different versions of Roblox available on Windows.
Most people use the version downloaded directly from the Roblox website. However, there is also a version available on the Microsoft Store (the "UWP" version). These two versions are technically different applications.
You can log into your main account on the browser/web version and then open the Microsoft Store version to log into your alt. It's a bit clunky because the Microsoft Store version can sometimes be buggy or have different keybindings, but it works perfectly if you only need two accounts running at once. It's the "official" way to do it without actually breaking any rules or using third-party mods.
How to Handle the Performance Hit
Just because you can run five instances doesn't mean you should without making some tweaks. Each instance of Roblox is going to eat up a chunk of your RAM and put a load on your graphics card. If you start seeing your frames drop to single digits, here's how to manage it:
- Lower the Graphics: This sounds obvious, but go into the settings of every instance and slide that graphics quality all the way down to 1. If you're just AFK farming, you don't need the game to look pretty.
- Use an FPS Unlocker: Ironically, sometimes unlocking your FPS or capping it at a very low number (like 15 or 30) for background windows can help save resources.
- Minimize Windows: If you aren't actively looking at an account, minimize the window. Some systems are better at "throttling" minimized apps, which frees up power for the account you're actually playing on.
Is This Allowed?
This is the big question everyone asks: "Will I get banned?"
To be totally honest, Roblox's Terms of Service are a bit of a gray area here. They don't specifically say "thou shalt not open two windows." However, they do have rules against "exploiting" or "automating" gameplay.
In practice, though, I've never heard of someone getting banned just for having two accounts open to trade items to themselves. Thousands of players do this every single day. The risk usually comes in if you start using "multi-boxing" software that mirrors your mouse clicks across all windows (which is definitely against the rules) or if you use it to bot a game server. If you're just sitting there with two windows open, you're generally going to be fine.
Common Issues and Fixes
Sometimes, even with the right tools, things go wrong. If you're trying to get roblox multiple instances free and it's still crashing, check these things:
- The "Account Kick" Error: If you try to join the same exact server with two accounts from the same IP, some games will kick you. This isn't a Roblox limitation; it's a script the game developer put in to prevent farming. You might need a VPN for one of the windows, but that gets complicated.
- Memory Leaks: Roblox isn't exactly the most optimized game. If you leave four instances running for 24 hours, don't be surprised if your computer starts acting sluggish. It's a good idea to restart all the windows every once in a while.
- Updates: Whenever Roblox pushes a major update (which happens almost every week), tools like Bloxstrap or Multi-Roblox might break for a few hours. Usually, the developers are quick to fix them, so just keep an eye out for updates.
Wrapping Up
Getting roblox multiple instances free is honestly a game-changer once you get it working. It makes those long grinds in simulators so much more bearable when you can have an alt account holding your extra items or helping you farm.
Whether you go with the "pro" route of using Bloxstrap, the classic Multi-Roblox tool, or just the simple Microsoft Store trick, you've got options. Just remember to keep an eye on your PC's temperature and don't push your hardware too hard. Happy farming!
