Liberty
by ThiefOfEden
Liberty is a client-side privacy and anti-griefing toolkit for Fabric that players install to limit what their game sends and receives.
What it does
Liberty works through a set of configurable filters that run on the player's own client. Its options are organized into five core domains with more than 60 settings in total. The filters can block telemetry, screen network payloads that look dangerous, hide streamer information, and throttle packet spam. Masking of usernames and skins, coordinate overlays and F3 screen edits are cosmetic, and they are handled on the local machine, so no data is sent to external servers.
The mod is built around a local-first approach. Saved data stays on the machine it was created on. Liberty is a client-side mod, so it is installed only on the player's side and is not needed on a dedicated server. It requires Fabric API, and Cloth Config API and Mod Menu are optional dependencies that add configuration screens. The files cover 26.2 only and are released under All rights reserved, so the mod is not open source.
Key features
Telemetry blocking
Outbound telemetry traffic to Microsoft and Mojang is stopped before it leaves the client.
Packet filtering
Dangerous network payloads are filtered and packet spam is throttled, limiting unwanted traffic.
Draft protection
Draft chat messages, including command drafts that begin with a hyphen, are prevented from being sent to the server by accident.
Cookie isolation
Cookie data is kept from being shared across server transfers.
SSRF sandbox
Resource pack URLs are scanned, and requests that point to private, local or loopback IP addresses are blocked.
Secure player skins
Skin retrieval is restricted to trusted Mojang domains over strict HTTPS, which blocks tracking through custom asset servers.

How it compares
GhostMode is a client-side mod for Fabric with an MIT License, open source and published for 1.21.11. Streamer Mode is also client-side only and open source under the CC0 1.0 Universal license, with files for 1.20 – 26.2. Local Identity is client-side and covers only 1.21.11, and its MIT License is not paired with open source here, since it is not open source.
