Joxblox

Joxblox is a cross-platform Fyne desktop app for exploring Roblox assets, scanning files and places for asset references, and working with the results in a desktop UI.

Features

The app currently includes five main workflows:

• Single Asset: inspect a Roblox asset, preview supported content, browse referenced child assets, and view raw response data
• Scan: scan folders or .rbxl/.rbxm files, diff results, filter/search rows, preview selected assets, and save or load JSON result sets
• Heatmap: turn .rbxl/.rbxm asset references into weighted map views with diff support and per-cell breakdowns
• Optimize Assets: find large image usage in a place file, filter candidates, resize them, and optionally upload optimized replacements
• Image Generator: generate PNG images in bulk and optionally upload them through Roblox Open Cloud

Other app features include:

• Mesh preview support for model assets
• Drag-and-drop JSON result importing
• Optional authenticated Roblox requests using .ROBLOSECURITY
• Embedded changelog and license info in release builds

Requirements
