Player Last Seen

Find out when a friend last played without searching server logs.

Use /seen <player> to check whether someone is online or see up to three recently recorded login and logout times. The records survive restarts, starting from when the mod is installed.

Any player can look up this activity; it is not limited to operators.

Server-side — install on the server only.

Player Last Seen

/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.

/seen Steve  → Steve is online right now.
/seen Alex   → Alex was last seen 2026-05-15 14:30 (about 1 day ago).
                 also seen 2026-05-13 22:10 (about 3 days ago)

It tracks login/logout server-side, keeps the last 3 sightings per player, and persists across restarts. /seen is open to all players, like EssentialsX's — anyone can query anyone's last-online, so it does reveal players' activity windows server-wide. In single-player, leave and re-enter the world to populate it. Output is localized in 9 languages.

It's a login/logout listener, persistent world data, and one command — no mixin, no config, no blocks or items.
