If macOS says the app is damaged on first launch, paste this in Terminal:
xattr -rd com.apple.quarantine /Applications/Threelane.app
Threelane is open source and signed ad-hoc (no Apple Developer certificate yet). This command clears the quarantine flag so the app opens normally.

Your phone is the second camera, in sync

Per-scene layouts
Screen. Camera. Phone. Split. Screen + camera bubble. Change any time. No re-recording.
Zoom & cursor follow

Desktop-grade, not browser-grade.
Native Mac app. Recordings don't stutter. Long sessions don't crash a tab.

MP4 export with ffmpeg
Industry-standard encoder. Clean output. No "processing…" spinner eating your afternoon.
Projects are just folders

Reels today, a YouTube tutorial tomorrow, a square clip for LinkedIn next week.
Portrait
Reels, Shorts, TikTok. Screen sits in a cover frame with your face in a bubble. No dead bars.
Landscape
Long-form YouTube. Screen + camera side-by-side. Cursor-follow zoom for the code-walkthroughs.
Square
LinkedIn, Instagram feed, podcast clips. Balanced framing that works everywhere.
Short answers.
Is it free?
Yes. No paywall, no trial, no credit card.
Does it work on Intel Macs?
Yes. Apple Silicon is the primary target, but Intel is supported.
Windows? Linux?
Not yet. Mac only. Multi-platform is on the radar, not the roadmap.
How is it different from Loom or Riverside?
Local-first. Multi-cam. Your phone as a second camera. Nothing ever uploaded, nothing gated behind a login.
Do I need to install anything on my phone?
No. Scan a QR code, open the PWA in your phone's browser, and hit record. Works on iOS and Android.
Where are my recordings stored?
~/Movies/Threelane/. Each project is a plain folder. Inspect it, move it, delete it.
Is this trying to replace Premiere?
No. It's the 90% case for creators who make one video a week and want it to look great in ten minutes.
Built with tools that respect your machine.
Three lanes. One click. Zero cloud.
Download Threelane and record your next video in ten minutes, end to end.
