PiForge

Visual project planning, engineered for Raspberry Pi.
Free, fully offline, and open-source desktop planner for RPi boards and GPIO wiring accessories.

PiForge sits at the intersection of hardware wiring, sprint planning, and system dependencies visualization — combining the wiring clarity of Fritzing, the sprint tracking efficiency of Linear, and the infinite visual design freedom of Excalidraw into a single offline-first workspace.

🎨 Features & Capabilities

• 🍉 Interactive SVG Canvas: An infinite panning and zooming stage. Drag-and-drop Raspberry Pi motherboard diagrams (Pi 5, 4B, Zero 2W, Pico, Pico W, etc.) and click individual pin headers to draw curved vector wires to sensors, relays, and OLED displays.
• 🛡️ Real-Time Hardware Diagnostics: An on-canvas schematic validator that alerts you to:
  • GPIO Pin Conflicts: Triggering warnings when multiple accessories are wired to the same physical pin.
  • Power Mismatch Errors: Warning if a 5V high-torque actuator (e.g. SG90 Servo, Relay) is incorrectly powered by a 3.3V rail.
• 💻 Firmware Code Scaffolding: Cross-compiles physical visual wiring directly into ready-to-run scripts.
  • Supported Standards: Python (gpiozero OOP, RPi.GPIO classic) and C++ (WiringPi).
  • Broad Catalog Coverage: Generates pin-accurate setups and operations for all 13 built-in accessories—including LEDs, Push Buttons, Rotary Encoders, DHT22 sensors, HC-SR04 sonars, SG90 servos, Relays, Buzzers, I2C OLED screens, Character LCD1602 screens, L298N H-bridges, MCP3008 ADCs, and DS18B20 1-Wire temperature sensors.
• 📋 Tactile Sprint Kanban: Columns dashboard utilizing native HTML5 drag-and-drop card trackers. Click a sprint card to access checklist task properties, timeline estimates, and calendars.
• 📝 Tabular Tasks Ledger: Spreadsheet-like ledger with instant inline priority adjustments and filter widgets.
• 🕸️ Force-Directed Graph: Uses Cytoscape.js to map your project's components and tasks as relational nodes, illustrating hardware layouts and software sprint blocks at a glance.
• 📚 Sanitized Documentation Editor: Markdown notes compiler that uses a split-pane layout to show HTML previews sanitized by DOMPurify.
• 📊 Bill of Materials Generator: Aggregates all canvas sensors to auto-generate a component list printable as vector PDFs or shared as Excel CSV sheets.
• 🔒 Off-Grid Sovereign Security: Completely offline and privacy-first.
  • Locks down scripts with a strict Content Security Policy (CSP) blocking external frames or script execution.
  • Features a 100% clean audit pass (0 vulnerabilities found via dependency checks and 0 warnings via strict Rust clippy static analysis).
• 📦 Local Portability (.piforge): Completely offline. Imports and exports self-contained sharing JSON archives representing your entire workspace.

⚙️ Technology Stack

• Desktop Shell: Tauri v2.x (Rust-based system IPC & tray orchestration)
• Frontend Compiler: SvelteKit v2.x in Single-Page Application (SPA) mode
• Reactive Engine: Svelte 5 (reactive stores & components bindings)
• Styling Compilation: Tailwind CSS v4.x
• Local Persistence: Offline SQLite database file via native Rust rusqlite
• Dependency Graph: Cytoscape.js

🚀 Dev Setup (macOS Apple Silicon)

Follow these simple instructions to initialize the developer environment:

1. Install System Dependencies

Install Node.js 20+, Rust toolchains, and package managers via Homebrew:

# Install Homebrew if missing
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

# Install Node & package manager
brew install node@20 pnpm git

# Install Rust toolchain
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
source ~/.cargo/env
rustup default stable
rustup target add aarch64-apple-darwin

2. Scaffold and Run Development Servers

Clone the repo, install packages, and boot up:

# Clone the repository
git clone https://github.com/pallab-js/PiForge.git
cd PiForge

# Install frontend libraries
pnpm install

To run a lightweight mockup browser server (great for rapid UI checking using localStorage fallbacks):

pnpm dev
# Opens http://localhost:5173

To launch the native Tauri desktop app (using the SQLite database inside application support):

pnpm tauri dev

📦 Bundling & Packaging

Compile the static client-side distribution folder and trigger the Tauri compiler to package native binary installers (e.g. .dmg on macOS, .msi on Windows, or .AppImage on Linux):

pnpm build
pnpm tauri build
