Hey 👋
Spantop turns any spare Mac or Android tablet into a wired/wireless extended for your Mac.
Use a second Mac or Android tablet as a HiDPI monitor over Wi-Fi, Thunderbolt, or USB-C. Powered by LZ4 for near-zero-latency streaming, with your screen staying local.
Sidecar only works with iPads. Spantop works with Macs and Android tablets too.
Free forever. Feedback welcome!
