Client-side Fabric mod that tells you everything your client can work out about the server you're on — where it's hosted, what software it runs, which plugins and mods it has, and how well it's ticking. One command, no server-side install.

Command

/serverinsight — Sends all details of the server in an organized structure

Features

Country flags in the server list: each server in the multiplayer list gets its host country's flag on the right-hand side. Hover it for the city, region, ISP, network operator and timezone.
Server details: address, MOTD, version, protocol, player count, difficulty, your permission level
Location: /serverinsight also reports where the address points, with the same details on hover
Server software: identifies Paper / Purpur / Folia / Spigot / Fabric / Forge / vanilla from the brand, with version, and tells you whether the server can run plugins at all. Detects when you're connected through BungeeCord, Waterfall or Velocity.
Server-side mods: lists mods the server declares network channels for — something no other client-side mod surfaces
Plugins, detected three ways and labelled by confidence:
- Reads namespaces from the command tree
- Tab-completes every plugin-listing command the server advertises (/version, /plugins, /pl, …)
- Recognises ~85 well-known commands (/lp → LuckPerms, /co → CoreProtect) — these are guesses, shown greyed out with a ? and counted separately as guess:
- Includes a copy button for the detected list and individual plugins
- Color codes popular plugins and security/anticheat plugins
Player details: gamemode, ping, coordinates
World details: dimension, biome, time, weather
Performance estimate: TPS, measured from the server's own tick counter

Note

TPS is an estimate, measured from the tick counter in the time packets the server sends. If a server doesn't send them, the mod says unknown rather than inventing a number.
Plugin detection is not guaranteed — many servers intentionally hide or restrict this information. The cmd: / tab: / guess: breakdown tells you where each result came from; anything marked guess: was inferred from a command name and is not confirmed.
Mod detection is a lower bound. A server-side mod that never talks to clients is invisible to it.
Flags show where the address points, not necessarily where the server hardware is. Anything behind a proxy, CDN or anycast network geolocates to the edge node.
Country lookups use a public geolocation API. Only addresses shown in your server list are looked up, results are cached, and private/LAN addresses are never sent. If you are offline or the lookup fails, flags simply don't appear.
This mod is client-side and does not need to be installed on the server.

1.2.0Релиз26.2 · 3 августа 2026 г.

Minecraft 26.2. Requires Fabric Loader 0.19.3+ and Java 25+.

Added

Country flags in the server list. Every server shows where it's hosted, to the right of the scrollbar. Hover a flag for the city, region, ISP, network operator and timezone.
Server software identification. Instead of a raw brand token, /serverinsight now names the software — Paper, Purpur, Folia, Spigot, Fabric, Forge, vanilla — with its version, and tells you whether the server can run plugins at all. Detects when you're connected through BungeeCord, Waterfall or Velocity.
Server-side mod detection. Lists mods the server declares network channels for.
Location line in /serverinsight, matching the server list flags.
Player count, protocol number, difficulty and your permission level.

Improved

Plugin detection now uses three methods instead of one, and tells you how much to trust each result. Alongside namespaced commands it tab-completes every plugin-listing command the server offers (/version, /plugins, /pl, and others), and recognises ~85 well-known commands such as /lp or /co.
The summary breaks results down as cmd: / tab: / guess:. Anything under guess: was inferred from a command name and is shown greyed out with a ? — a command name is a hint, not proof.
"None detected" now explains itself. On a vanilla or modded server, no plugins is the correct answer rather than a sign the server is hiding something.

Fixed

TPS no longer invents a number. It used to report a confident 20.00 whenever it had no data, so servers that don't send timing packets looked perfect. It now says unknown. The estimate itself is also measured properly, from the server's own tick counter rather than assuming a fixed packet interval.
Removed ms/t. It was calculated as 1000 / TPS — the TPS reading restated and presented as a second measurement. Real ms/t is server-side tick time, which a client cannot see.
No more freeze on slow DNS. The address lookup ran on the render thread and could hang the game for seconds; it now happens in the background.
Fixed a timing bug that counted every server tick update twice.

Notes

Flags show where the address points. Anything behind a proxy, CDN or anycast network geolocates to the edge node, not the machine running the game.
Country lookups use a public geolocation service. Only addresses in your server list are looked up, results are cached, and private/LAN addresses are never sent. Offline, flags simply don't appear.
Mod detection is a lower bound — a server-side mod that never talks to clients is invisible to it.
