A workshop, not a product line

Small tools, built local-first and let loose.

Sudama Labs is where standalone software experiments get a home. Each one runs entirely in your browser — no accounts, no uploads, nothing to install. This is the first.

Local-first — your data never leaves the device Zero-install — open a page, that's it Single-file — the whole app is one HTML document

Experiment 01

Webcam Studio

● Live

A high-quality webcam and screen recorder that runs in a single browser tab. Record yourself, your screen, or both — with a teleprompter that listens to your speech and highlights the next words as you say them, so you can read a script without ever looking away from the lens. Everything is captured and saved locally; nothing is uploaded.

Webcam or screen share, with live picture-in-picture overlay
Speech-following teleprompter (or steady timed scroll)
Adjustable pace, font size & highlight — live, mid-recording
Burned-in watermark, previewed exactly as it records
MP4 (H.264/AAC) or WebM up to 4K / 60fps, pause & resume
Every setting and your script saved on-device
