RimModFetch

A lightweight, native C++ Win32 GUI utility to batch-download Steam Workshop mods for RimWorld directly via SteamCMD.

Features

• Native Win32 GUI with zero bloated dependencies.
• Extracts Steam Workshop IDs automatically from raw links, text, or number lists.
• Removes duplicate mod IDs before downloading.
• Automatically reads About.xml and displays actual mod names in the status log.
• Copies downloaded mods straight into your RimWorld Mods directory.

Requirements & Setup

1. Download SteamCMD from Valve's official site and extract it (default path: C:\steamcmd\).
2. Run steamcmd.exe once to let it download its core files.
3. Launch RimModFetch.exe.
4. Verify paths to steamcmd.exe and your RimWorld Mods folder.
5. Paste Workshop URLs or IDs into the text box and click Download & Install.

No Steam credentials needed mod downloads use anonymous authentication.
