Show HN: A screen recorder/editor that runs in browser

Demoreel, a screen recording and editing tool that runs entirely in the browser, launched on Show HN. The project was shared by the creator, mehrant, as a demonstration of what's possible with in-browser recording and video editing.

The tool allows users to record their screen and edit footage directly in a web interface, eliminating the need to download software or use desktop applications. By running in the browser, Demoreel removes friction from the capture-and-edit workflow for demos, tutorials, and other screen-based content. The application is accessible at demoreel.app.

The launch on Show HN reflects growing interest in web-based creative tools that shift processing and storage away from local machines. Browser-based editors have become increasingly viable as web standards improve and JavaScript performance strengthens, particularly for media work. Screen recording and editing are workflows traditionally dominated by desktop applications like ScreenFlow, Camtasia, and OBS Studio, each requiring installation and often substantial computing resources.

The post appeared on Hacker News on September 12, 2026, where it was shared by its creator as a working prototype rather than a funded venture or established company.
