how to find out the RAM and GPU information of my visitors?

Question

I want to know how much RAM my visitors have and all the information available about their GPU. Is there any way to achieve this via JavaScript or maybe ActionScript (Flash)?

Highly unlikely JavaScript can do this, and it's a little shady to use otherwise pointless Flash (which might be able to do this but I'm not really sure) to determine private system configuration data. – Capsize

Why not just have users download and run a survey app if they want to give you this data, the way Steam does it? Or upload a dump from an existing tool for this like CPU-Z. – Capsize

Answer 1

JavaScript, Browser extensions and Plugins are heavily sandboxed that they have limited, to no access to the system for security purposes. Only limited hardware can be accessed directly (with the user's consent), like camera and microphone for JavaScript's getUserMedia or Flash.

The nearest you can get is to have the user install something on the PC that interacts with the browser, like a Java applet. Can You Run It uses this method to check the user's PC if it matches game requirements.

Answer 2

Use

navigator.deviceMemory

To find the device RAM in gigabytes.

See browser support.

Just here to point out. navigator.deviceMemory only returns the approximate amount of system memory, it is used to identify classes of devices (low-end, mid tier, and good tier) – Applecart

Answer 3

To determine the client's RAM, use navigator.deviceMemory To get GPU information you can use some tools like: https://github.com/pmndrs/detect-gpu/tree/master
