Tailscale is a powerful app that protects users on random Wi-Fi networks, offers convenient ways to connect to their devices, and creates a private network for accessing files and data. It's open source software with an easy install process and clear documentation, making it accessible to developers and individuals alike. Tailscale is free, unlike many VPNs which can cost anywhere from $5 to $30 per month. Users can access their home devices remotely, share files, and access sensitive data securely, without relying on a business or company's logging of traffic. The app also offers private secure networking, protecting users' online activities from being tracked or monitored by third parties. With Tailscale, users can create an exit node to protect themselves on public Wi-Fi networks and access their home network remotely, making it an ideal solution for those who need to stay connected and productive on the go.
