ChatStack

by betterclient

ChatStack groups repeated chat messages on the client, so a message sent several times shows once with a count beside it.

FabricClient-side onlyMIT LicenseOpen source1.16 – 1.21.5

What it does

When the same message arrives more than once in a row, ChatStack places the copies on top of each other instead of listing them. A number next to the line shows how many times it appeared, and the count is colored so repeats stand out at a glance. The grouping happens only on the player's own screen and changes nothing on the server.

The mod runs on Fabric for game versions 1.16 – 1.21.5, across 29 release versions, and is released under the MIT License as open source. Because it is client-side only, players install it in the mods folder and servers need nothing. The latest Fabric build, 1.1.0, targets 1.21.5 and was published on 2025-05-17, three days after the first release on 2025-05-14.

Key features

  1. Message stacking

    Identical chat lines that arrive back to back are merged into one entry at the top of the chat.

  2. Stacked message numbering

    Each grouped line carries a counter showing how many copies were received.

  3. Colored counts

    The repeat counter is colored, so grouped messages can be told apart from single ones.

  4. Chat-only change

    Grouping applies to the chat window alone, leaving the rest of the client interface as it was.

How it compares

Full comparison

Compact Chat is also a client-side chat tweak under the MIT License, but it is published for both Fabric and NeoForge across 1.17.1 – 1.21.11. Stacked Actionbar Messages applies the same stacking idea to the action bar rather than the chat, and is limited to 26.2 – 26.3 on Fabric. Fabric Brand Fix is unrelated to chat and changes the brand string sent to servers.
