Built with .NET 10 and Avalonia UI, it works on Windows, macOS, and Linux.

Features:

• Smart updates: Change title, description, tags, or visibility without re-uploading your mod content or preview image. The app tracks file path, size, and modification date: only uploads when something actually changed!
• Multi-game support: Manage mods for multiple Steam games (switch between workshops easily)
• Visual editor: Edit title, description, tags, and preview image
• Drag & drop: Simply drop your mod folder to create a new item
• Changelog management: add changelogs with each update
• Auto-fetched tags: Workshop tags are automatically retrieved for each game
• Custom tags: Add your own tags per game
• Multi-language: English, French,... supported
• PlainText or BBCode: Customize your description and changelogs with the tags currently offered by Steam.

• Steam must be running
• .NET 10 Runtime (framework-dependent builds)
