No Elytra Boost
by Sputniknull
No Elytra Boost is a server-side Fabric mod that stops firework rockets from boosting players gliding with an elytra.
What it does
When a player uses a firework rocket during elytra flight, the mod cancels the boost, and the rocket is consumed. The check runs as an event callback that intercepts the use action before the game processes it, rather than through a datapack, which keeps the tick processing simple and avoids race conditions. Because the mod only adds a single callback, its effect on server performance is described as zero by the author.
The mod targets servers that want to encourage other forms of travel, such as walking, boats, minecarts or the nether network, instead of rocket-assisted flight. Only the server needs it, so players join without installing anything. It requires Fabric Loader and Fabric API, and the files cover Minecraft 1.21.11 only.
Installation means dropping the jar into the server mods folder and restarting the server. The license is CC0 1.0 Universal, which places the work in the public domain, so it is not open source under the usual definition.
Key features
Rocket boost blocking
Firework rockets used during elytra flight no longer add speed, so gliding keeps its normal pace.
Rocket consumption
Each rocket used is consumed anyway, so the item is still spent when the boost is cancelled.
Event-based check
The mod intercepts the rocket use action before the game handles it, instead of changing a datapack.
Server-only install
Only the server runs the mod, so no client-side installation is needed for players to join.

Use cases
Alternative transport
Server owners who want players to travel by foot, boat or minecart can keep rockets from doing that work for them.
Who it’s for: Server owners who run Fabric servers on Minecraft 1.21.11 and want rocket-assisted gliding turned off. Single-player players and clients on other versions do not need it.
How it compares
No Firework Boosting is also server-side only and covers 1.20 – 1.21.5 under CC0 1.0 Universal, so it reaches more versions but ends at 1.21.5. No Wasting Rockets is a client-side Fabric mod for 1.21.1 under the GNU General Public License v3.0 only, which is open source; it works on the client and does not affect servers.
