I'm the builder of Threelane. Here's how I made it and why.

Hey Product Hunt,

I'm the builder behind Threelane, shipping it from Dubai.

Why I built it

I make a lot of product demos and tech reels. Every smooth multi-cam tool I tried was either subscription-locked, cloud-locked, or both. Loom is fine for talking heads but breaks once you want a second camera. Riverside is great but pricey and online-only. ScreenStudio nailed cursor zooms but it's Mac-only and paid. Nothing was free, local, AND multi-cam. I got tired of waiting for someone to build it, so I did.

How I built it

The challenge wasn't recording. Capturing a screen and a webcam is solved. The hard part was making your phone act as a sync'd second camera over WiFi without capture cards, NDI boxes, or extra hardware. I built a small companion PWA that runs on the phone. Scan a QR from the desktop app, and you've got a synced second cam streaming over your local network. The desktop side is Electron with native capture APIs, with a custom multi-track timeline editor on top.

Shipped under MIT, no premium tier, no signup, no cloud. Footage never leaves your laptop.

Would love feedback, especially from anyone who's wrestled with multi-cam workflows. What am I missing?
