After months of building, testing, and refining, MouseViz is here.

MouseViz is a native macOS app that records and visualizes mouse activity in real time. It shows where you click, how you move, and where you hesitate — rendered as heatmaps, trails, click pulses, spotlights, and dead zones directly on your screen.

Why we built this

UX researchers and designers have always relied on web-based tools to understand user behavior. But what about native apps? Desktop workflows? Complex multi-window setups?

There was no good answer. Existing tools either required browser extensions, worked only on websites, or produced static reports hours after the session ended.

MouseViz works differently. It captures mouse events system-wide — across every app, every window, every screen — and renders the visualization live, as an overlay on top of whatever you're doing.

What you can do with it

Record sessions with a floating control bar inspired by Screen Studio and CleanShot
Visualize in real time with five modes: heatmap, trail, click pulses, spotlight, and dead zones
Run UX studies with task scripts, session markers, and AI-powered analysis
Compare sessions side by side to spot behavioral differences
Export high-resolution images and videos of your recordings

Built for the Mac

MouseViz is a true macOS citizen. It lives in your menu bar, uses native AppKit and SwiftUI, and respects your system permissions. No Electron, no web views, no server required. Everything runs locally on your Mac.

What's next

We're just getting started. The roadmap includes session replay, webhook integrations, team collaboration features, and deeper AI analysis. Follow along on the changelog or check the roadmap for what's coming.
