Player Last Seen
by KURONAMI
Player Last Seen records when each player last logged in or out and lets anyone query that history with a command on the server.
What it does
The mod tracks login and logout events on the server and keeps the last three sightings for each player. These records are stored as persistent world data, so they survive server restarts. A single command reports when a player was last online, and the output is localized into nine languages.
Vanilla servers on NeoForge and Fabric have no built-in last-seen command, and the EssentialsX plugin only runs on Paper and vanilla servers, which leaves a gap for other setups. Player Last Seen fills that gap with a server-side listener and a mixin-based configuration for blocks and items. Single-player sessions also populate the records when a player leaves and re-enters the world. Fabric API is required on Fabric, and the mod is published for Fabric, Forge and NeoForge files covering 1.20.1 and 1.21.1.
Installation is server-side only, so players join without installing anything. The mod is free to use in modpacks, and its source code is public, though it is not open source and remains under All rights reserved.

What the author says
/seen [player] — when was this player last online? The last-seen lookup that vanilla NeoForge and Fabric servers don't have. Vanilla has no last-seen, and the plugin that does (EssentialsX) only runs on Paper, not on vanilla NeoForge/Fabric servers. This adds the command as a mod.
