Hey Product Hunt 👋 I built Spantop because I often wanted a second monitor without carrying one around. Spantop lets you turn another computer or device into a real second monitor for your Mac over Thunderbolt or WiFi. It is made for people who travel, work from cafés, use multiple screens, or just want more space without buying extra hardware. The goal was simple: open the app, connect another screen, and extend your Mac workspace. Would love your feedback — especially from Mac users who use multi-monitor setups, travel often, or work across multiple devices.

@aditya_dewaskar congrats with the launch! What features are free and what require a paid update? It would be nice to see the app in action somehow, maybe even captured from your POV using an iPhone, I think that might boost interest/conversion for you. Good luck!

nice! does it work with windows? I mainly use mac for work, but still sometimes switch to windows for creative work, and connecting mac as a second monitor was always difficult with third party software.
