Sill

Sill is a free, open-source remote desktop application that displays and controls individual Mac windows or an entire desktop from an iPhone or iPad. It streams captured content using Apple's ScreenCaptureKit and HEVC video encoding for responsive visual performance. Users can interact with Mac applications through touchscreen gestures, Apple Pencil, virtual trackpads, and connected keyboards. The software supports local network connections, USB cables, direct wireless links, and remote access through a personal VPN. TLS 1.3 encryption protects supported connections without requiring cloud accounts or intermediary servers. Additional capabilities include bidirectional text clipboard sharing, adjustable window sizing, and optional virtual displays. Sill runs on Apple silicon Macs with macOS 14 or later and mobile devices running iOS or iPadOS 17 or later. It emphasizes privacy and low-latency remote interaction.
