ServerLogViewer
ServerLogViewer lets a player read a Paper server's logs from the Fabric client, with search and filtering by log level.
What it does
Server logs are normally only visible on the machine running the server. This Fabric mod adds a menu to the game that shows those messages on the client, so a player can view them without opening the server console. Installing it needs a matching Paper plugin on the server, and the plugin's configuration has to be set up before the logs reach the client. After changing that configuration, the plugin usually needs to be touched again.
The mod is aimed at developers and server staff who check output while playing. Messages can be searched quickly and filtered by log level, and the menu explains what each control does. Each message can be traced back to its origin plugin. The client part depends on oωo (owo-lib), which must be installed alongside it. Only the client needs the mod; the server side is handled by the separate Paper plugin.
Files are published for Fabric on Minecraft 1.21.8 and 1.21.10, with 1.0.1 for 1.21.10 as the latest release, dated 2025-11-23. The project is open source under the MIT License, and its source code is public.
Key features
Log viewer menu
A menu inside the game lists the server's messages, and a short description explains what each control does.
Search and level filters
Messages can be searched and narrowed by log level, so a specific warning or error is quick to find.
Plugin origin
Each message can be queried by the plugin that produced it, which helps when several plugins write to the log.
Installation pairing
The Fabric client and the Paper plugin are installed as a pair, and the installation details are kept on the plugin's page.
