Screenize
Free, open-source Screen Studio alternative for macOS
Record your screen. Let auto-zoom do the rest.
You record a demo, a tutorial, or a quick walkthrough. Screenize watches your cursor and clicks, then zooms, pans, and adds effects on its own. No manual keyframing needed.
Unlike paid alternatives, Screenize is **free** and gives you **control** over every zoom, transition, and effect through a timeline editor.
## Project Status (May 22, 2026)
Development of Screenize is currently paused.
I started Screenize because there was no open-source Screen Studio-style app with automatic editing features. I wanted to build something useful for myself and other indie hackers. Since then, newer open-source projects such as [Recordly](https://github.com/webadderallorg/Recordly) have appeared and raised the quality bar for screen recording and editing tools.
Because the original reason for continuing Screenize is no longer as strong, I do not plan to actively develop it for now. Screenize will remain open source. If these alternatives move in a commercial-only direction, I may return to active development.
## Why Screenize?
**You don't need to pay $89+ for polished screen recordings.**
- **Auto-zoom that gets it right.** Two smart camera modes: one follows your cursor in real time with spring physics, the other plans zoom levels per activity (typing, clicking, scrolling, dragging). Both are customizable down to the smallest detail.
- **Timeline editor, not a black box.** Don't like how a zoom turned out? Edit it. Every auto-generated keyframe is visible and adjustable on a multi-track timeline.
- **Click effects & keystroke overlays.** Ripple animations on clicks, keyboard shortcut badges (⌘C, ⇧⌘Z) on screen. Your viewers see what you're doing.
- **Make it look good.** Gradient backgrounds, rounded corners, shadows, custom cursors, motion blur on fast transitions. The result looks like you spent hours on it.
- **Export your way.** MP4, MOV (ProRes), or GIF. Up to 4K, up to 240fps. sRGB, Display P3, BT.709, BT.2020. Save presets for your workflow.
- **Capture everything.** System audio + mic, screen or single window, 720p to 4K, variable frame rate for smaller files.
- **6 languages.** English, Korean, Chinese, Japanese, French, and German.
## Install
**Homebrew (recommended)**
```bash
brew install --cask thedavidweng/tap/screenize
```
**Manual download**
Grab the latest `.dmg` from [GitHub Releases](https://github.com/syi0808/screenize/releases) and drag Screenize into Applications.
> **First launch on macOS:** Since Screenize isn't notarized with Apple yet, macOS will show a warning. Right-click the app, select **Open**, and confirm. You only need to do this once.
### Permissions
On first launch, Screenize asks for four permissions:
| Permission | Why |
| --- | --- |
| Screen Recording | Capture your screen |
| Microphone | Record audio |
| Input Monitoring | Track clicks and keystrokes |
| Accessibility | Detect UI elements for smart zoom |
## How It Works
1. **Pick a screen or window** and hit record
2. **Do your thing.** Screenize tracks your cursor, clicks, and keystrokes in the background
3. **Open the editor.** Auto-generated zoom and effects are already on the timeline
4. **Tweak if needed.** Adjust any keyframe, add click effects, change cursor styles
5. **Export.** One click, done
### Keyboard Shortcuts
| Shortcut | Action |
| --- | --- |
| `Cmd+Shift+2` | Toggle recording (global hotkey) |
| `Cmd+N` | New recording |
| `Cmd+R` | Start/stop recording |
