Description
Hi HN, like many of you talented folk, I’ve been building more, faster than ever. I built Saggar after my terminal stopped feeling like a tool and started feeling like a tab-management problem. Let me know you think!

Could you build this?
No Building a high-performance native macOS terminal emulator with PTY session multiplexing, terminal sequence parsing, process lifecycle monitoring, and low-latency mobile companion sync requires deep systems programming.
What it would actually take: Built with Swift/AppKit or Rust (Metal/CoreText rendering engine) managing pseudo-terminals (POSIX PTYs) and ANSI/VT100 state machines. The core complexity lies in real-time heuristic process inspection to classify waiting/working states, crash-safe terminal emulation, and secure WebRTC/WebSocket relay to the mobile companion.
