Lumiko

Lumiko is a Chrome-based screen recorder that edits footage automatically while you record. It tracks your cursor and clicks to build smooth zoom and pan moves without keyframes, and includes a browser timeline for trimming, splitting, and reordering clips. Additional tools include Smart Blur for hiding sensitive text, a webcam bubble, custom backgrounds, click effects, and exports up to 4K. It runs locally with no account or upload queue and is free to start.
