Why FirmHub?

Everything you need to flash firmware — nothing you don't.

Zero-Trust Security

All firmware operations happen locally in your browser. No data ever leaves your machine — not even telemetry.

Precision Flash Engine

Advanced flashing with integrity verification, memory mapping, multi-partition staging, and automatic baud-rate detection.

Full Transparency

Real-time serial logs, live signal monitoring, and complete visibility into every byte written — exportable at any time.

Universal Device Support

ESP32, ESP8266, RP2040 Pico, Arduino AVR, and NVIDIA Jetson — one unified platform for all your boards.

Built-In Capabilities

Professional-grade tools, zero compromises.

Multi-Binary Staging

Stage bootloader, partition table, and application binaries with custom hex offsets.

Live Serial Monitor

Real-time serial plotter with baud-rate switching and log export.

Memory Mapping

Visual flash memory layout showing partitions, free space, and firmware segments.

Performance Metrics

Live write speed, ETA countdown, data throughput, and verification status.

Web Serial API

Direct hardware access through Chrome/Edge — no drivers, no installs, no middleware.

ScriptForge IDE

Built-in code editor for editing config files, scripts, and partition tables.

Supported Boards

Flash these boards directly from your browser.
