Mobile Tmux/Shell Access Portal

A lightweight, secure mobile app that lets developers access long-running terminal sessions (tmux, shells, background processes) from their phone with TLS encryption and optional Tailscale integration. Solves the gap between SSH/Mosh and mobile terminal access without security compromises.

Tailscale's explosive growth and the broader zero-trust networking shift have made secure remote access a genuine developer priority rather than an afterthought, which creates real timing for a polished mobile-first layer on top of that infrastructure. Blink Shell on iOS and Termius already occupy this space with paying userbases, so the question isn't whether demand exists but whether differentiation on tmux-specific UX and Tailscale-native integration is enough to displace entrenched habits. The $2k–10k/mo revenue band is plausible but tight — this is a tool developers will pay $8–15/month for, which means you need hundreds to low thousands of subscribers to hit the ceiling, and churn will be brutal the moment a free alternative improves. The biggest risk is that Termius or a well-resourced open-source project ships Tailscale integration and collapses the differentiation entirely before a defensible user base is built.
