TailMux.

TailMux

TailMux enables macOS and Linux users to access multiple independent Tailscale tailnets simultaneously without switching accounts or creating conflicting VPN interfaces. By routing traffic based on hostname suffixes, it maintains strict isolation between profiles while keeping your official Tailscale client session untouched—making it ideal for developers and IT professionals who need seamless access to work, personal, and client networks from a single machine.

Product Highlights

• Concurrent Multi-Tailnet Access: Connect to resources across multiple independent Tailscale networks at the same time without account switching or VM overhead.
• Hostname-Based Routing: Automatically directs traffic to the correct profile using hostname suffix matching, with hard isolation preventing cross-profile leaks.
• Embedded tsnet Architecture: Each profile runs its own isolated Tailscale node with separate state, keys, and sockets—no system-wide VPN conflicts.
• Zero-Config Browser Integration: Auto-generated PAC proxy settings enable seamless Safari and browser access with no manual network configuration.
• CLI-First Design: Complete control through a comprehensive command-line interface, with optional menu bar and web GUI wrappers for convenience.
• Secure Service Tunnels: Pin databases, RDP, SMB, and other services to fixed local ports with persistent connections and SSH bastion support.

Use Cases

• Multi-Account Development: Developers working across client, employer, and personal infrastructure can access all environments simultaneously without constant re-authentication.
• DevOps & Platform Engineering: Operations teams managing resources across segregated production, staging, and internal networks maintain clean separation with transparent routing.
• Security-Conscious Consulting: IT consultants accessing sensitive client tailnets alongside their own infrastructure benefit from enforced isolation and audit-friendly connection logging.
• Hybrid Work Environments: Remote workers connecting to both corporate VPN resources and personal home labs eliminate the friction of native account switching.

Target Audience

TailMux is designed for technical professionals—software engineers, DevOps practitioners, system administrators, and security-conscious consultants—who regularly work across multiple Tailscale networks and need reliable, scriptable, and isolated access without the complexity of VMs or the limitations of native account switching.
