AntiFreecam
by Kesuaheli
AntiFreecam is a Fabric mod that lets a server decide whether players can use collision-free camera movement, regardless of what each client has set.
What it does
The server sets its own collision rules from a config file that can be reloaded, and the mod enforces them on every player who joins. The server cannot tell whether a player has a freecam mod installed, because the freecam mod does not communicate with the server, so the rule applies to every player, including those without any freecam mod. When a player joins, the server notifies the client that collisions are always enforced, and the client's own settings are overridden.
AntiFreecam runs on both the server and the client, so the client side is needed to honor the forced collisions. Players must install it to join a server that uses it, and the mod merges client code from the Freecam mod to do so. Files are published for Fabric only, with 1.0.5 for 26.2 as the latest build, and the source code is open source under the MIT License. Fabric API is required, and Freecam is optional. The mod covers 1.21.5 – 26.2 across seven release versions, and the author lists some features as planned for the future.
Key features
Forced collision checks
The server forces collision checks on clients, so freecam movement through solid blocks is not allowed in play.
Reloadable server config
The config file can be reloaded without a server restart, and it decides which collisions are allowed.
Freecam prevention
Freecam use can be blocked altogether, rather than only turning off collisions for one player.

Use cases
Who it’s for: Server owners running Fabric who want to control collision behavior, and players who join those servers. Players must install the mod on the client to connect.
How it compares
Vigils Anti-Cheat is a server-side only Fabric mod for 26.2, released under the MIT License, so players join it without installing anything. OFF Client is a client-side only Fabric mod for 1.21.11 – 26.3 under All rights reserved, so it changes nothing on the server. AntiFreecam is client and server, open source under the MIT License, and covers 1.21.5 – 26.2.
