// BROWSER-BASED · NO DOWNLOAD · NO EXTENSION · INSTANT
An online screen recorder that actually works without downloading software or installing a browser extension. This tool runs as a standard web page and uses the getDisplayMedia API built into Chrome, Edge, and Firefox. No plugin, no desktop app, no signup form. The moment you open this page, you are ready to record.
The recording happens entirely in your browser. When you click Start, the browser shows a native dialog that lets you choose what to share: your full screen, a specific application window, or a single browser tab. Optional microphone input lets you add narration. The output is a WebM video file created locally on your device, never uploaded to any server. You can record as long as you need, at up to 2.5 Mbps quality, and download the result instantly when you stop.
The tool is built on three Web APIs. First, getDisplayMedia captures the visual content of your screen, window, or tab as a video stream. Second, getUserMedia optionally captures microphone audio. Third, the Web Audio API mixes these streams together if both are active.
A MediaRecorder object receives the combined stream and collects data in chunks as the recording progresses. When you stop, the chunks are assembled into a Blob and wrapped in a WebM container with VP9 video and Opus audio codecs.
The resulting file is made available through a local object URL. You can preview it in the built-in video player and download it with one click. No data is transmitted to any server during or after the recording.
Quick recordings that do not justify installing dedicated software. If you need to capture a 2-minute walkthrough of a web page, firing up OBS or Camtasia would take longer than the recording itself. An online tool lets you start immediately.
Shared or restricted computers where you cannot install software. Work machines with IT policies, library computers, or borrowed laptops all have browsers that support screen recording natively.
Remote collaboration where you need to show your screen asynchronously. Instead of scheduling a video call, record your screen with commentary and share the file. The recipient watches on their own time.
Desktop screen recorders require installation, updates, and sometimes substantial disk space. OBS alone is over 200 MB. Browser-based recording uses zero disk space, receives no updates (the browser handles that), and is available on any device with a modern browser.
Cloud-based recorders like Loom upload your video to their servers, which raises privacy concerns for sensitive content and introduces upload wait times. This tool keeps everything local. Your recording never leaves your device unless you explicitly choose to share it.
