Screen
Recorder

Yes — completely free, no account, no watermark, no time limits, and no usage caps. Recording uses your browser's native screen-capture API, and the video is encoded locally with MediaRecorder, so there is no server to pay for or limit you.

Nowhere but your device. The recording is encoded in your browser's memory and downloaded directly to your computer as a WebM file. It is never uploaded, stored, or processed on a server — which matters when you're recording sensitive dashboards, client calls, or unreleased work.

The recorder outputs WebM (VP8 or VP9 video with Opus audio), the format your browser's MediaRecorder produces natively. WebM plays in Chrome, Firefox, Edge, and most modern players; it also imports directly into DaVinci Resolve and other editors. On Safari the recorder falls back to MP4 where supported.

Yes. When you pick 'browser tab' as the capture source, you can enable 'Share tab audio' in the browser's share dialog to record the tab's sound (music, video, presentations). System-wide audio from other apps is restricted by browser security — for that you would need OBS or an OS-level tool.

Screen capture and microphone access are sensitive permissions, so the browser shows a confirmation dialog every time — by design. The dialog lets you choose what to share (entire screen, a window, or a tab) and whether to include audio. You can stop sharing at any time by clicking the browser's 'Stop sharing' indicator.

OBS is a powerful desktop app but has a steep learning curve and needs installation. Loom is cloud-based: your recordings are uploaded to their servers and free accounts have limits and watermarks. This tool is the middle ground — one click to start, native browser quality, zero install, zero upload, and your video stays on your machine.
