When a game, a 3D viewer or a graphics heavy application misbehaves, the first question a support team asks is what graphics hardware the machine actually has. The browser can answer part of that question through WebGL, the graphics API it uses for 3D content: the renderer string typically names the graphics processor and driver path the browser is using. This checker reads that renderer and vendor information where the browser exposes it, and reports whether WebGL is available at all. Where the information is masked or unavailable, which is increasingly common for privacy reasons, the page says so plainly instead of guessing a model name from a generic string.
Quick Answer: Click Check GPU Info. The WebGL renderer and vendor strings appear where available, or a clear message explains that they are masked.

GPU Info Checker
Your browser’s WebGL renderer and vendor, where exposed.
How to Use the GPU Info Checker
- Click Check GPU Info in the browser you want to inspect.
- Read the renderer string, which usually names the graphics processor the browser is using.
- Read the vendor string and the WebGL support status alongside it.
- If the strings are masked, compare with another browser or check your operating system’s display settings for the full model name.
- Share the renderer string, not a screenshot of the whole page, when reporting a graphics problem.
Key Features
- WebGL renderer reporting, giving the graphics processor name as the browser sees it.
- Vendor string reporting, identifying the graphics driver provider behind the renderer.
- WebGL support detection, confirming whether 3D graphics are available in this browser at all.
- Honest masked data handling, with a clear message when the browser withholds detailed strings.
- Private local reading: graphics information is displayed on your screen and sent nowhere.
Best Practices and Tips
- Check in the browser where the problem occurs, since different browsers may report different renderers on the same machine.
- A renderer mentioning SwiftShader or a software renderer usually means hardware acceleration is disabled or unavailable.
- Keep graphics drivers updated when 3D content fails, since many WebGL problems are driver problems, not application bugs.
- Use the renderer string for support reports, because a model name alone does not identify the driver version in use.
Common Mistakes to Avoid
- Assuming a masked renderer string means the graphics hardware is broken, when it usually means the browser is protecting privacy.
- Treating the browser’s renderer as a complete hardware specification, when it omits memory size and driver version details.
- Comparing renderer strings across operating systems and expecting them to match character for character.
Frequently Asked Questions
What is a WebGL renderer string?
It is a text label the browser’s graphics system reports for the GPU and driver path in use, for example a model family name from the graphics vendor. Applications read it to decide which rendering features to enable, and support teams use it to identify the hardware involved in a graphics problem.
Why is my renderer masked or generic?
Browsers increasingly mask detailed graphics strings to reduce device fingerprinting, where a precise hardware label helps track a device across sites. A masked string protects privacy but still confirms that WebGL works, and your operating system’s settings remain the source for the exact model.
Does this check my graphics card’s memory or speed?
No. It reports identity and availability only. Memory size, clock speed and benchmark performance need operating system tools or dedicated hardware utilities, which a web page cannot reliably measure.
What does a software renderer mean?
It means the browser is drawing 3D content with the processor instead of the graphics card, usually because hardware acceleration is off or the GPU is blocked. 3D content will still work, but it will be slower and may struggle with demanding scenes.
