ValiMod

ValiMod is an advanced server security and synchronization tool for Fabric that ensures connecting clients match the server's required mod environment.

Features

• Automated Handshake: Verifies client mod lists, version numbers, and active resource pack SHA-1 hashes during login.
• Anti-Bypass Protection: Enforces a 10-second connection timeout—clients that drop or ignore the handshake request are automatically kicked.
• Configurable Enforcement: Define required mods, exact versions, allowed mods, or blacklisted mods in config/valimod.json.
• Smarter Kick Messages: Displays stylized disconnect notices with optional clickable links so players can quickly download missing modpacks.
• Hot-Reload Support: Reload configuration files instantly using the /valimod reload command without restarting the server.
• Warning Mode: Toggle enforceKicks to false to log violations without kicking players—perfect for auditing client environments safely.

Configuration

Edit config/valimod.json on your server to set your rules:

{
  "enforceKicks": true,
  "downloadUrl": "[https://modrinth.com/modpack/your-modpack](https://modrinth.com/modpack/your-modpack)",
