Record your screen in the browser
Recording your screen for a demo, tutorial or bug report is a common need. This tool records your screen, a window or a browser tab, with optional microphone audio, directly in your browser.
Why in-browser recording helps
Screen recording usually means installing software, but the browser can capture your screen, a specific window, or a single tab, with your microphone audio, using built-in capabilities. This is ideal for a quick demo, a tutorial, or capturing a bug to show someone, without installing anything. Recording in the browser also means the capture stays on your machine, you save the resulting file locally, rather than being uploaded to a service. It covers the common screen-recording needs simply, for anyone who does not want to install a dedicated tool.
Capture without installing
It runs entirely in your browser, so nothing you enter is uploaded and it works without an account, keeping your data on your own machine.
