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.
