Opportunity score
42/100
A neatly executed niche utility with a clear audience but limited revenue potential due to one-time pricing and reliance on a single ecosystem.
Founder verdict
MAYBE
A beautifully executed micro-tool solving a real headache for Tailscale power users, but too niche to become a high-growth business on its own.
What is TailMux?
TailMux is a lightweight, CLI-first utility that enables developers and IT professionals to access resources across multiple independent Tailscale tailnets concurrently from a single macOS or Linux machine. It uses hostname-suffix-based routing through embedded tsnet nodes, ensuring hard isolation without modifying the system's official Tailscale client. The product addresses the common pain point of juggling accounts or spinning up VMs when working with separate work, personal, and lab tailnets.
