AI Analysis

●●SolidNiche GemSlick

tmux alternative with live GPU monitoring, but mosh and tmux already solve persistence.

Strengths
  • •Tauri + Rust build means lighter than Electron terminals like Warp or Tabby
  • •Open-source ~4MB daemon handles PTY sessions independently of SSH connection
  • •Real-time GPU utilization and VRAM tracking per session is genuinely useful for ML work
Weaknesses
  • •Session persistence isn't novel — tmux, screen, and mosh have done this for years
  • •AI agent orchestration feels tacked on rather than core to the terminal experience
Target Audience

ML engineers, backend developers managing remote GPU clusters

Similar To

Post Description

Hey HN! I built Haven because I wanted the feeling of the native MacOS terminals with all of my work across different remote GPU machines. Before Haven I had multiple vs code windows SSH'd into different machines, each running tmux. I'm now 100% on Haven and my token usage has nearly doubled since the switch (in a good way), and seems to reduce my cognitive load with managing multiple agents. Still early development but would love to get some feedback from SSH-heavy devs & ml eng. - Christian
