Hidder is the Fabric client companion to ModSeeker. It reports your mods and, when requested, a detected launcher label to the server you join. The server owner decides which mods and launchers are allowed.
|
ModSeeker is required on the serverPlayers install Hidder on their client. Server owners install the ModSeeker Paper plugin to use its reports and enforce their rules. |
Features
| Feature | Description |
|---|---|
| Automatic verification | Responds to the server's checks when you join, without player commands or a separate app. |
| Protected mod reports | Signs and encrypts mod reports for the connected server. |
| Bundled native library | Includes its Windows library; no separate OpenSSL or C++ runtime installation is needed. |
Compatibility
Client platform: Windows x64 · Mod loader: Fabric · Dependency: Fabric API
Choose a Hidder JAR for your Minecraft version. Each supported target accepts Fabric Loader 0.19.3, 0.19.5 or 0.20.1; you do not need a different Hidder file for each of those Loader versions.
| Minecraft version | Java |
|---|---|
| 1.21, 1.21.4, 1.21.7, 1.21.8, 1.21.9, 1.21.10, 1.21.11 | 21 |
| 26.1.2, 26.2, 26.3 | 25 |
The download labelled mc26.1 is for Minecraft 26.1.2. Fabric API must also match your Minecraft version. Other Fabric Loader versions are not supported by this release.
Getting started
- Create a Fabric instance for your Minecraft version and select one of the three supported Loader versions above.
- Download the matching Hidder JAR and Fabric API.
- Put both files in that instance's
mods/folder, then launch Minecraft. - Join a server running ModSeeker v3. Verification happens automatically.
If a server rejects a mod or launcher, follow its disconnect message or contact the server owner. The server's policy determines what is allowed.
What Hidder sends
Reports go to the Minecraft server you join, through the existing game connection. Hidder does not use a separate telemetry service.
| Data | When it is sent |
|---|---|
| Mods | IDs and version strings during mod verification, including entries found in declared bundled mod JARs. |
| Mod file hashes | When the server requests advanced verification. These SHA-512 hashes let ModSeeker check approved files. |
| Launcher | In response to a launcher challenge. ModSeeker requests this when launcher verification is enabled; the result is a launcher label or unknown. |
| Verification | Hidder presence, version information, request IDs, signatures and verification errors. |
Hidder reads mod JARs and launcher information locally. It does not upload JAR contents, local file paths or raw process details. It does not report hardware IDs, resource packs or shader packs.
Server administrators can read these reports. ModSeeker logs mod lists to its console by default, and server owners can also enable Discord notifications.
