What is it?

Web ScreenRec is a lightweight screen recorder that runs in the browser, so users can record their screen without installing a native application. It works across platforms as long as a supported browser is available.

The tool can record the screen, microphone and desktop audio at the same time. Recordings can be converted to MP4 with ffmpeg using a single button. It can be run by opening the public/index.html file directly in a browser, or started with Docker Compose.

Because recording permissions depend on CORS headers, the site must be served by its included web server rather than a plain static HTTP server. Accessing it over the internet requires HTTPS/TLS.

Key features

  • 01Records screen, microphone and desktop audio simultaneously.
  • 02Requires no installation and runs in the browser on any supported platform.
  • 03Converts recordings to MP4 with ffmpeg via a single button.
  • 04Can be launched by opening a local HTML file or with Docker Compose.

Use cases

  • Quickly recording a demo or tutorial on a machine where installing software is not allowed.
  • Capturing screen and voice narration together without setting up a separate recording app.
  • Self-hosting a private screen recording page for a team with Docker.
