Important
PicoForge is an independent, community-developed tool and is not affiliated with or endorsed by the official pico-fido project. This software does not share any code with the official closed-source pico-fido application.
Check application Installation Wiki for installation guide of the PicoForge app on your system.
PicoForge only supports v7.2 of the PICO FIDO series of firmwares. Support to v7.4 and above is WIP.
PicoForge is a modern desktop application for configuring and managing Pico FIDO security keys. Built with Rust and GPUI, it provides an intuitive interface for:
- Reading device information and firmware details
- Configuring USB VID/PID and product names
- Adjusting LED settings (GPIO, brightness, driver)
- Managing security features (secure boot, firmware locking) (WIP)
- Real-time system logging and diagnostics
- Support for multiple hardware variants and vendors
BETA Status: This application is currently under active development and in beta stage. Users should expect bugs and are encouraged to report them. The app has been tested on Linux and Windows 10 with the official Raspberry Pi Pico2 & ESP32-S3 and, currently supports Pico FIDO firmware version 7.2 only.
- Device Configuration - Customize USB identifiers, LED behavior, and hardware settings
- Security Management - Enable secure boot and firmware verification (experimental and WIP)
- Real-time Monitoring - View flash usage, connection status, and system logs
- Modern UI - Clean, responsive interface built with Rust and GPUI
- Multi-Vendor Support - Compatible with multiple hardware variants
- Cross-Platform - Works on Windows, macOS, and Linux
Check the official PicoForge Wiki for installation info of the application.

To contribute to PicoForge, you'll need:
- Rust - System programming language (1.80+)
- PC/SC Middleware:
- Linux:
pcscd(usually pre-installed) - macOS: Built-in
- Windows: Built-in
- Linux:
git clone https://github.com/librekeys/picoforge.git
cd picoforgeTo run the application in development mode:
cargo runTo build for production:
cargo build --releaseThe compiled binary will be available in target/release/picoforge (Linux/macOS) or target/release/picoforge.exe (Windows).
Nix provides developers with a complete and consistent development environment.
You can use Nix to build and develop picoforge painlessly.
Follow the Installation Guide and NixOS Wiki to install Nix and enable Flakes.
You can build and run PicoForge with a single command:
nix run github:librekeys/picoforgeOr simply build it and link to the current directory:
nix build github:librekeys/picoforgeTip
You can use our binary cache to save build time by allowing Nix to set extra-substitutes.
Download the package definition:
curl -LO https://raw.githubusercontent.com/librekeys/picoforge/main/package.nixRun the following command in the directory containing package.nix:
nix-build -E 'with import <nixpkgs> {}; callPackage ./package.nix { }'The compiled binary will be available at: result/bin/picoforge
You can enter a developement environement with all the required dependencies.
nix develop github:librekeys/picoforgeYou can use the shell.nix file that is at the root of the repository by running:
nix-shellThen you can build from source and run the application with:
cargo runpicoforge/

Warning
PicoForge is experimental software and still in the Beta stage! The app does contain bugs and is not secure by any means.
It does not support all the features exposed by the pico-fido firmware and pico-hsm.
