YUNG's Better Strongholds

YUNG's Better Strongholds is a world-generation mod created by YUNG. Completely overhauls vanilla strongholds with sprawling layouts, grand libraries, armouries, and prison cells. As a world gen mod it concentrates on terrain, biomes, and the shape of the world itself, and it has been downloaded around 20 million times, which puts it among the options players reach for in this space.

YUNG's Better Strongholds is built for players who want strongholds redesigned as memorable dungeons. It replaces the maze-like vanilla stronghold with a grander structure full of new rooms, loot, and atmosphere on the way to the End. It is approachable enough to drop into a world and use right away, with little setup required.

The mod is available for Forge, Fabric, and NeoForge, so it fits a range of modpacks and launchers. It currently supports Minecraft 1.20.1 and 1.21.1, spanning the 1.20.1 to 1.21.1 releases. It runs on both the client and the server, so on a multiplayer server every player who connects needs it installed alongside the server itself.

YUNG's Better Strongholds works particularly well alongside YUNG's API. It depends on YUNG's API, so those must be present and on the same loader and version. Because it ships for both Fabric and Forge-family loaders, it slots into most popular modpacks regardless of which side they are built on.

YUNG's Better Strongholds has a modest footprint for what it adds and is widely used in modpacks without notable performance concerns.

If you are comparing options, similar mods include YUNG's Better Dungeons and YUNG's Better Mineshafts. They cover comparable ground, so the right choice usually comes down to your loader, version, and the rest of your pack.
