Graphics Card Exposure Test

Sometimes, your graphics card's details are exposed to the web. Yours are not right now, though, which is good. Try opening this page in different browsers – I found Chrome had much more information than Firefox, for example.

The Code

//Function to grab GPU data. const getGPU = () => { const ctx = document.createElement('canvas').getContext('webgl') const ext = ctx.getExtension('WEBGL_debug_renderer_info') return { card: ctx.getParameter(ext.UNMASKED_RENDERER_WEBGL), vendor: ctx.getParameter(ext.UNMASKED_VENDOR_WEBGL), } } //Put the GPU data into the web page. const gpu = getGPU() document.getElementById('graphics-card-test-output') .textContent = `Yours is ${gpu.vendor}'s ${gpu.card}.` tags: webgl, privacy, demo, web dev
