Server Insight

Command

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

Features

• Server details: address, MOTD, version, brand (when available)
• Plugins:
  • Reads namespaces from the command tree
  • Checks Tab-completion
  • 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 + ms/t (derived from server time update packets)

Note

• TPS and ms/t are estimates, based on timing packets the server sends.
• Plugin detection is not guaranteed — many servers intentionally hide or restrict this information.
• This mod is client-side and does not need to be installed on the server.

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.
