A visual node-graph editor for building PowerShell scripts. Drag, connect, run.

What is PoSHBlox?

PoSHBlox lets you visually compose PowerShell scripts by wiring together nodes on a canvas. Each node represents a cmdlet, control-flow block, or custom script fragment. Connections between nodes define the data pipeline. When you're done, export a clean .ps1 file.

Features

• Node palette with 50+ built-in cmdlet templates across 9 categories (File/Folder, Process/Service, Registry, Network/Remote, String/Data, Output, Control Flow, Custom, Annotation)
• Control flow containers -- If/Else, ForEach, Try/Catch, While loops, Functions, and Labels -- with support for nesting containers inside containers
• Live script preview and one-click Run in a PowerShell 5.1 window
• Pipeline-aware code generation -- chains piped cmdlets, assigns variables at branch points, and detects cycles
• Module import -- import cmdlets from installed PowerShell modules to extend the palette
• 10 sample projects included to demonstrate common patterns
• Keyboard shortcuts -- P (palette), F5 (run), Ctrl+S (save), Ctrl+E (export), Del (delete node), / (search), and more
• Dark theme with a custom node-graph renderer (pan, zoom, Bezier wires)

Getting Started

Prerequisites

• .NET 10 SDK

Build & Run

git clone https://github.com/obselate/PoSHBlox.git
cd PoSHBlox
dotnet run

Publish

Build a self-contained single-file executable:

dotnet publish -c Release -r win-x64 --self-contained

Output lands in bin/Release/net10.0/win-x64/publish/ — just the exe, Templates, and Scripts folders.

How It Works

1. Add nodes from the palette
2. Connect output ports to input ports by dragging wires
3. Configure parameters in the right-side properties panel
4. Preview the generated script, then Run or Save as .ps1
