Potion seeker

by GRIZZLY_DEV

Potion seeker shows the status effects of nearby loaded players as icons floating above their heads, a client-side view of effects that vanilla does not display.

What it does

Potion seeker draws effect icons above other players who are close enough to be loaded on the client. The icons use the same style as the vanilla HUD, so they read like the effects already shown on the player's own screen. Where the server sends exact status-effect packets, the icons list the real effects; where it does not, the mod falls back to entity metadata that Minecraft 1.21.11 sends for potion swirls, and to the particle data of the effects.

Two optional displays extend this view: a through-wall rendering mode, and a marker for players with no effects that helps when troubleshooting visibility. A self-effect display can be shown above the hotbar. Settings are handled by a Mod Menu configuration screen. The mod requires Fabric API and runs on Fabric for 1.21.11 only, with the latest file, 1.7.3, published on 2026-06-12. It is released under All rights reserved and is not open source.

Key features

  1. Effect icons above players

    Active effect icons appear above nearby loaded players, using vanilla HUD-style icons.

  2. Exact effect data

    When the server sends exact status-effect packets, the mod lists the real effects on each player.

  3. Fallback detection

    Without exact packets, effects are inferred from potion swirl metadata and visible vanilla effects, which can be less precise for stacked effects.

  4. Optional rendering modes

    Through-wall rendering and empty-player markers can be switched on, along with a self-effect display above the hotbar.

Questions

Does Potion seeker need Fabric API?

Yes. Fabric API is a required dependency, and the mod runs on Fabric only.

Does the server need to install Potion seeker?

No. Only the player's game needs it, and servers run without it.

Why might some effects look different from the exact list?

When the server does not send exact status-effect packets, the mod uses the fallback data, which cannot always tell stacked effects with identical visuals apart.

What the author says

The fallback is reliable for common visible vanilla effects, but stacked effects or effects with identical visual particle data may not always be distinguishable perfectly.
