Free, open-source alternative to Screen Studio for recording product demos and walkthroughs. No subscriptions, no watermarks, free for commercial use. Self-described as "a much simpler take, just the basics" rather than full Screen Studio parity.
What it does:
- Capture specific windows or full screen
- Auto or manual zoom effects with adjustable depth
- Record mic + system audio simultaneously
- Crop, trim, adjust playback speed per section
- Motion blur on pan/zoom transitions
- Annotations: text, arrows, images
- Backgrounds: wallpapers, solid colors, gradients, custom
- Export in multiple aspect ratios and resolutions
Tech stack: Electron, React, TypeScript, Vite, PixiJS (for graphics rendering), dnd-timeline (for the timeline UI).
Platform notes: macOS needs screen recording + accessibility permissions (and Gatekeeper bypass without dev cert). Linux needs PipeWire for system audio. Windows system audio works out of the box.
