I'm Abner, solo developer in Brazil. Fieldhand gives you a shell in the browser, health data and fleet commands for Linux devices already in the field: kiosks, signage, lockers, gateways on 4G.
Those devices sit behind CGNAT and customer firewalls, so nothing can connect in. The agent is one static Go binary that dials a single WebSocket over TLS on 443. You install it on the OS that's already there, no reflash.
Remote shell, health monitoring, alerts and fleet commands for Linux devices in the field (kiosks, digital signage, lockers, EV chargers, IoT gateways), behind 4G, CGNAT and firewalls. One static agent, outbound-only, no reflash.
