What it does
Drive
Keyboard, mouse or your own gamepad, through a small input device on the console's USB port. On-screen Joy-Con light up with every press.
Let agents drive
An HTTP API and an MCP server with 23 tools. You see every agent action live, and one switch blocks agent input.
Test
Repeatable JSON tests with screenshots and a clip of the moments before any failure. A doctor tells you which part is broken.
Offline by design
An optional console network answers only the connectivity test. No forwarding, no NAT, no internet, and it can't be turned off.
Yours
Light, Peach, Dark and OLED themes and 11 languages. Everything stays on your computer; nothing is uploaded.
How it connects
Linux board
Luckfox, Raspberry Pi Zero 2 W, Pi 4/5. Every button, including C, GL and GR in Pro Controller mode. Keyboard and mouse.
Raspberry Pi Pico
The cheapest controller option, with a 3.3 V USB-to-UART adapter. Keyboard and mouse too.
CH9329
A keyboard and mouse for the console, no controller.
View only
Just a capture card: watch, record, take screenshots and read text.
For AI agents
The MCP server is built into the app. Add it to Claude Code, Codex, opencode or any MCP client, then ask your agent to open a menu, read the screen or run a test, and watch it work.
