  • Open browser DevTools Console & Network tab before starting capture.
  • Drag downloaded WebM directly into GitHub PRs or Slack threads.

About This Tool

Recording quick screen captures for bug tickets, software demos, and technical pull requests shouldn't require installing heavyweight desktop software or uploading sensitive proprietary code to third-party cloud recorders. This browser-based recorder taps directly into the standard Screen Capture and MediaRecorder APIs.

Capture entire displays, application windows, or isolated browser tabs with optional synchronized voice narration. All video frames are encoded directly into memory on your computer, producing high-fps WebM videos ready for instant download and sharing.

Key Features

  • Zero cloud uploads: Video frames never leave your local computer; recording and encoding execute strictly in browser memory.
  • Full tab, window, or monitor capture: Select exactly what you want to share using your browser's native privacy-isolated picker.
  • Microphone audio mixing: Optionally record synchronized voice narration alongside system audio.
  • Zero watermarks & no limits: Completely unconstrained recording with no brand overlays, forced subscriptions, or artificial limits.
  • Instant WebM download: Exports standardized WebM video streams directly compatible with Slack, GitHub, Jira, and Discord.

Frequently Asked Questions

Are my screen recordings stored or uploaded anywhere?
No. The recording is held solely in local browser memory (RAM) as a Blob. Nothing is uploaded, tracked, or relayed through our servers.
How do I attach my recording to a GitHub issue or pull request?
GitHub natively supports WebM and MP4 video attachments up to 100MB. Simply download the recorded video and drag it directly into the issue comment box.
Can I capture internal system audio along with my screen?
Yes. When choosing a browser tab or whole screen in Chrome, Edge, or Firefox, check the "Share system audio" or "Also share tab audio" checkbox in the browser prompt.
Is there a duration limit on recordings?
There is no artificial limit. Duration is bounded only by your machine's available RAM. Recordings up to 30 minutes are smoothly handled on standard laptops.
