Write Frothy, run complete forms on a connected board, and inspect its live words from the browser.

1. Plug in a board that runs Frothy over USB. Supported ESP32 and RP2040 boards work.
2. Choose Connect and select the board.
3. Run File runs the open file, splicing in its include directives; running main.fr starts from a clean board. Run Line runs the line at the cursor, or the whole block from its opening or closing line.
4. Edits and the project title save automatically.

Board stuck in a saved loop? Connect and choose Interrupt and connect when offered. On an ESP32 board, you can also hold the BOOT button right after you press EN to skip saved code.

Web Serial requires a desktop Chrome, Edge, or Opera browser.
