remotely ssh Raspberry Pi in web browser

Devs often use SSH to manage RPi or IoT devices. SSH (Secure Shell) is a network protocol for establishing terminal sessions to connect to other computers. SSH is typically used for local network machines or servers with public static IPs. However, IoT devices are often behind firewalls blocking all inbound traffic for data security. This makes accessing/managing devices deployed at remote sites behind firewalls challenging. Troubleshooting may require sending techs to the field for on-site connections, which significantly increases IoT device management complexity and cost.
