You’ve been there. A new trailer drops for a game that looks absolutely stunning, but your PC is basically a glorified toaster from 2019. You head over to Google, type in the name of the tool everyone uses, and then pause. A thought hits you: is Can You Run It safe to use, or are you about to hand over the keys to your digital life just to see if you can play Cyberpunk 2077 at 30 frames per second?
It’s a valid worry. We’re taught from day one never to download random .exe files from the internet. Yet, System Requirements Lab—the actual name of the site—has been around since the early 2000s. Millions of people use it. But longevity doesn't always equal security.

Let's be real about what’s happening under the hood. When you click that button to "View Requirements," the site asks you to download a small desktop applet. That’s the moment most people get the "ick." Why can't it just read your specs through the browser? Well, modern browsers are sandboxed for security. They aren't allowed to poke around your hardware components like your GPU's exact VRAM or your BIOS version. To get that data, the site needs a foot in the door.
Breaking Down the Security of System Requirements Lab
The tool, technically called the Detection App, is a small piece of software that scans your hardware. People often ask, "is Can You Run It safe for my privacy?" Here is the deal: the applet looks at your CPU, your graphics card, your RAM, and your DirectX version. It doesn't go through your browser history. It isn't looking at your tax returns or your weirdly specific folder of cat memes.
The software is digitally signed by Husdawg, LLC. This is a big deal in the tech world. A digital signature means the file hasn't been tampered with since it was created by the developer. If a hacker tried to inject malware into that specific download, the signature would break, and Windows would scream at you with a bright red warning.
I’ve looked at the behavior of this app using basic network monitoring tools. It’s quiet. It runs, it gathers the hardware strings, it sends them back to the web server, and then it basically goes dormant or closes. It’s not a persistent background process that eats your CPU cycles like some sort of crypto-miner.
Why the Antivirus Sometimes Freaks Out
Sometimes, your antivirus might flag it. This is what we call a "false positive." Because the tool acts like a "system information gatherer," security software like Norton or Bitdefender might think, "Hey, this thing is snooping!" Technically, it is snooping—but you asked it to. It's the difference between a doctor checking your pulse and a stranger grabbing your wrist on the subway.
The Accuracy Trap: Why "Safe" Doesn't Always Mean "Right"
Safety isn't just about viruses. There is also the "safety" of your wallet. If the site tells you that you can run a game, and you spend $70 on Steam only to find out it runs like a slideshow, that’s a different kind of danger.
System Requirements Lab compares your hardware against the "Minimum" and "Recommended" specs provided by the game developers. Here is the secret: those specs are often total guesswork. Developers usually target a specific resolution, like 1080p. If you’re trying to play on a 1440p monitor, the "Recommended" specs on the site might actually be "Minimum" for you.
- The VRAM Issue: The tool is great at seeing how much memory your GPU has. It's less great at understanding the architecture. An old 4GB card is not the same as a modern 4GB card.
- CPU Bottlenecks: It might say your i7 processor is "Pass," but if that i7 is ten years old, the instructions per clock (IPC) won't keep up with a modern budget i3.
- Driver Status: It checks your driver version, which is actually super helpful. Old drivers are the number one reason games crash on launch.
Honestly, the site is a bit of a blunt instrument. It's awesome for a quick "yes/no" vibe check, but it’s not the Bible of PC performance.
Privacy Concerns and Data Collection
Is Can You Run It safe regarding your personal data? They do collect information, but it’s mostly aggregated. They want to know "What percentage of our users have an RTX 4090?" This data is incredibly valuable for hardware manufacturers and game devs. It’s a trade-off. You get a free service; they get to see the hardware trends of the gaming public.
If you’re the kind of person who uses a VPN for everything and clears their cookies every hour, you probably won't like the idea of the applet. But for the average gamer? It’s significantly safer than downloading "cracked" software or using sketchy "PC Optimizer" tools that pop up in shady ads.
Better Alternatives for the Tech-Savvy
If you still feel uneasy about downloading the detection tool, you don't actually need it. You can check your specs manually and compare them. It takes three minutes.
- Press Windows Key + R.
- Type
dxdiagand hit enter. - Look at the "System" tab for your RAM and CPU.
- Look at the "Display" tab for your GPU.
Once you have that, go to a site like PCGameBenchmark or even just look at the Steam store page. Another fantastic resource is YouTube. Seriously. Type your GPU and CPU name into the YouTube search bar followed by the name of the game (e.g., "GTX 1650 Ryzen 5 3600 Cyberpunk benchmark"). You will see actual gameplay footage of someone with your exact setup. That is a thousand times more useful than a "Pass/Fail" bar on a website.
Common Misconceptions About the Tool
I've seen people claim that using the site slowed down their computer. That’s almost certainly a coincidence. The applet is tiny. It doesn't install a service that runs at startup. If your PC is slow after using it, you might want to check your Chrome tabs or see if Windows Update is running in the background.

Another myth is that it's a "scam" to get you to buy new parts. While the site does have affiliate links to Amazon or Newegg for upgraded parts, that's just how they pay the bills. They aren't lying to you about your specs just to make a buck. If it says your GPU is old, it’s probably because your GPU is old.
The Browser-Only Version
Did you know you can use it without the download? You can. You just have to manually type in your specs. It’s more tedious, but it completely bypasses the security concerns. If you’re asking is Can You Run It safe, and your gut says "maybe not," just use the manual entry. Your peace of mind is worth the extra thirty seconds of typing.
Expert Verdict on System Requirements Lab
After two decades in the industry, the consensus is clear. System Requirements Lab is a "Legacy" site. It’s old-school. It’s cluttered with ads. It looks like it hasn't been redesigned since 2012. But it isn't malicious.
The danger isn't a virus. The danger is the "Recommended" settings giving you a false sense of security. Games today are notoriously unoptimized at launch. Even if the site says you "Pass," always check the recent Steam reviews to see if the game is a broken mess for everyone.
Actionable Steps for Safe Performance Checking
If you want to check your gaming compatibility without risks, follow this protocol. First, use the manual search on System Requirements Lab if you are worried about the applet download. This gives you the data without the software. Second, always verify the results against YouTube benchmarks of your specific hardware; seeing real FPS (frames per second) is better than a checkmark. Third, keep your graphics drivers updated via GeForce Experience or AMD Software, as the site often flags "Fail" simply because your drivers are out of date. Lastly, if you do use the detection tool, you can simply delete the .exe file immediately after the scan is finished. It doesn't need to stay on your system to work for that session. By following these steps, you ensure your PC stays clean while getting the info you need to avoid wasting money on games you can't actually play.
