Antigravity Serial Monitor

Features

Everything the desktop app can do — organized around how you actually debug hardware.

Board Profiles

Select ESP32, Arduino AVR, STM32, RP2040, Teensy, nRF52, Pico, or generic serial. The UI unlocks tabs based on board capabilities.

Serial Console

High-speed UART monitoring with filters, pause/resume, auto-scroll, reset, copy, export, and quick command macros.

Serial Plotter

Turn key=value, CSV, or numeric lines from the monitor into simple live charts — great for sensor tuning.

Device Info

Live chip details when connected, firmware hints (Improv, MicroPython, CircuitPython, ESP-AT), and profile info when idle.

Firmware Flash

Flash presets, full backup/erase, region-scoped erase, and register access for ESP32 family boards via WebSerial esptool.

Partition Map

Visualize bootloader, app, NVS, and filesystem partitions. Inspect integrity and download flash regions on demand.

Filesystem Browser

Unified hub for SPIFFS, LittleFS, and FATFS — upload, download, rename, and manage files on supported ESP boards.

NVS Inspector

Browse and edit Non-Volatile Storage entries when your partition table includes NVS — useful for configuration debugging.

Desktop Flash Tools

Arduino and other profiles invoke bundled or system tools (avrdude, bossac, st-flash, picotool). Reconnect after flash in one click.

Flexible Baud Rates

Standard and custom baud rates with board-aware defaults. Higher-baud suggestions when your hardware supports them.

Light & Dark Themes

Glass-inspired UI with light and dark modes — readable on the bench, in the lab, or at 2 AM.

Browser & Desktop

Chromium Web Serial for Espressif maintenance in the browser. Full flash-tool support requires the desktop build.

Every tab exists for a reason. If it doesn’t help you ship firmware faster, it doesn’t belong here.
