Built with .NET 10 and Avalonia UI, it works on Windows, macOS, and Linux.
Features:
- Home dashboard: KPI cards plus a list of your recent mods, all on the new top-bar shell
- 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)
- Worker-process Steam: Steam runs in a separate process, so switching between sessions does not freeze the UI
- Visual editor: Edit title, description, tags, and preview image — Info / Changelog / Versions tabs in a card-based layout
- Drag & drop: Simply drop your mod folder to create a new item
- Changelog management: add changelogs with each update
- Multi-version support: declare which game versions a mod is compatible with (when supported by the game)
- Real game names: fetched from the Steam Store API instead of bare AppIds
- 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
- Optional usage statistics: opt-in telemetry feeds the public dashboard at swm-stats.com — pseudonymous, no Steam ID, full opt-out from Settings → Privacy
- Steam must be running
- .NET 10 Runtime (framework-dependent builds)

Usage statistics are opt-in and pseudonymous: every record is tied to a per-install random UUID with no link to a real-world identity. Telemetry is dispatched only after explicit consent through the setup wizard (new installs) or a privacy-preferences modal (upgrades from previous versions).
What is sent: instance UUID (random, generated locally), operating system + version, application version, UI language, event types (app launch, mod created/updated/deleted, session added), Steam AppId per event, two-letter country code resolved at the Cloudflare edge.
What is not sent: Steam IDs, Steam usernames, account information, mod titles or descriptions, file paths, or any personal information.
The aggregated public dashboard lives at swm-stats.com. The full policy and the deletion request workflow are documented at swm-stats.com/Privacy. Telemetry can be toggled at any time from Settings → Privacy, and the per-install UUID is displayed there with a copy button so it can be quoted in deletion requests.
