Slackbridge
by transcental
Slackbridge relays chat between a Minecraft server and a Slack channel, and posts join, death, advancement and start or stop notices there.
What it does
Messages typed in the game chat are forwarded to a configured Slack channel, and Slack messages are sent back into the server chat. Threads in Slack are excluded from the relay, so only top-level channel messages cross over. The bridge is a simple Fabric mod built for chat exchange and nothing else.
Beyond chat, the mod posts server events to Slack: player joins and leaves, deaths, advancements, and the server starting or stopping. It is server-side only, so players join without installing anything. Slackbridge is published for Fabric alone, with a single build, 1.0.0 for 1.21.1, on the beta channel since 2024-09-28, and its source is open source under the MIT License.
Public links exist for the source code, the issue tracker and the wiki. Releases are distributed through GitHub, where each build is published alongside its notes.
Key features
Two-way chat relay
Game chat is posted to a Slack channel, and messages sent in that channel appear in the server chat.
Thread filtering
Slack thread replies are not relayed, which keeps the in-game chat limited to channel-level messages.
Join and leave notices
Player joins and leaves are announced in the Slack channel as they happen.
Death and advancement posts
Player deaths and advancements are sent to Slack, giving a record of notable events on the server.
Server start and stop messages
The channel receives a message when the server starts and when it stops.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
Use cases
Community servers
Server owners who keep a Slack workspace for their players can see chat and events in the same place as the rest of the team.
Who it’s for: Server owners and administrators who already use Slack for their community or staff chat. Because the mod runs only on the server, players need nothing installed to take part.
How it compares
Just Chat Range is a Fabric mod for 1.21.11 that is server-side only, and its license is All rights reserved, so its code is not open source. No Join Leave Messages is a server-side Fabric mod for 1.21 – 1.21.11 under the GNU General Public License v3.0 only, and it is open source. Blocketing is server-side only and open source under the MIT License, but it targets 1.21.5 – 1.21.10 instead of 1.21.1. Slackbridge is the only one of these that posts to Slack.
