Free open-source GPU-accelerated screen recording/demo editor for Windows, macOS and Linux.

What is OpenScreen?
OpenScreen is a free, open-source desktop app for recording the screen and turning the recordings into product demos and walkthroughs. It runs on Windows, macOS and Linux, is released under the MIT license, and requires no account and adds no watermark. It records a window or a full display with microphone and system audio, plus an optional webcam in picture-in-picture, dual frame or vertical stack layouts; a Full Camera mode expands the webcam to full screen for part of the timeline.
New recordings are zoomed where the user clicked, using a fixed rule rather than AI, and the pointer is recorded separately from the screen pixels so its size and style can be changed afterwards. The editor adds backgrounds, padding, shadows, motion blur, 3D camera moves, device frames, blur regions, annotations, and crop, trim and speed controls. Captions are transcribed on the user's machine with whisper.cpp, and deleting words in the transcript cuts the timeline.
Exports are MP4 (H.264, 720p up to source, at 24, 30 or 60 fps) or GIF, in aspect ratios including 16:9, 9:16 and 1:1, with GPU encoding and an automatic CPU fallback. An optional AI chat assistant applies edits such as cuts, zooms and speed ramps after the user connects a provider with their own API key; it is off by default. A headless command-line interface and an MCP server let scripts, CI and coding agents record, edit and export videos, and an openscreen-demo skill lets a coding agent attach the finished video to a pull request.
OpenScreen continues the original project created by Siddharth Vaddem, which was archived after v1.5.0; the community-maintained continuation is led by Etienne Lescot. The publisher states that the app is free for personal and commercial use, with no paid tier or premium features.
Pricing: Free and open source (MIT) for personal and commercial use; no paid tier, premium feature, account or watermark
