compressy
by strixun
Compressy lets players stack blocks into denser compressed versions, up to 32 tiers, with the compressed blocks still usable in recipes and automation.
What it does
Standard recipes work for each compression tier, so hoppers and machines can feed the chain. Compressy detects vanilla blocks and modded blocks automatically, which removes the need to configure each one by hand. Placed compressed blocks keep their compression when broken, so a stack of storage does not shrink on the way down.
Each tier is marked with Roman numerals and a darkening effect, and tooltips are color-coded with the block count they hold. Compressed blocks have an enchantment glint so they stand out in a storage room. The mod is open source under the MIT License and is published for Fabric only, on 1.21.11. Every player and the server need a copy of the mod. A premium plugin for MC v26.2 is listed alongside it as a separate product.
Key features
Up to 32 compression tiers
Each recipe compresses nine blocks of the previous tier, so one block can represent a very large number of originals.
Visual tier indicators
Roman numerals and a darkening effect show the tier of each compressed block at a glance.
Color-coded tooltips
Tooltips show the tier and the block count in color, so the amount inside a stack is readable without counting.
Automation-friendly recipes
Standard crafting recipes are used for every tier, so hoppers and machines can compress and decompress items.

Use cases
Long-term storage
Players who gather large amounts of one resource can keep it in a few compressed blocks instead of many chests.
Who it’s for: Players who run storage systems and server owners who want a compact way to hold large stacks of blocks. The mod needs basic operator commands on a server.
How it compares
Compression is a separate mod that also compresses blocks, but it is published for Fabric and NeoForge over 1.21.8 – 1.21.11 and is not open source. Chronos Timer is a client-side only Fabric mod on 1.21.11 under the MIT License, so it adds no compression and needs nothing on the server. Enchant Tooltips is open source under the MIT License, client-side only, on Fabric for 1.20.4 – 1.21.
