Show HN: Haven – persistent SSH sessions without tmux

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

Love this already using the mac version and it has helped me keep tabs on my agents even when I'm in transit

Interesting—what’s the failure mode compared to tmux/screen? With tmux I mostly rely on the server-side persistence, so even if my client drops completely I can just reattach. Are you maintaining state client-side, or is there still something running server-side to keep sessions alive?

Server-side yes - the app ships with its own open-source remote daemon that gets setup when you connect to the server
