I didn't want to pay $20/mo for a screen recorder, so I vibe-coded one

I've been paying for screen recording tools for years. Loom, Screen Studio, the usual lineup. Every time I hit the free-tier ceiling I'd grumble, pay, and move on.

A few weeks ago I stopped grumbling and opened Claude Code instead.

Threelane is what came out - a desktop screen recorder with a built-in editor. Three things I wanted that nothing else gave me in one app:

• Three lanes, one recorder. Screen + webcam + iPhone (paired over WiFi via QR) recording into a single timeline.

• Cursor-following zoom lanes. The Screen Studio feature I actually pay for. Drop a zoom lane, it tracks your cursor automatically.

• One recording, every aspect ratio. Re-crop the same take for Shorts, YouTube, and square social without re-recording.

The whole thing is local-first nothing leaves your laptop, no account, no upload. And it's MIT licensed and free forever because honestly, this shouldn't be a subscription.

What vibe-coding actually changed for me: I would never have started this two years ago. A native cross-platform desktop app with multi-cam capture, video encoding pipelines, and a timeline editor was a "nope, not my stack" project. With AI in the loop, the activation energy collapsed. I shipped Mac, Windows, and Linux builds.

Would love your feedback especially on the editor UX.
