Sidebar Potion display
by c10udburst
Sidebar Potion display shows the status effects active on a player in a compact sidebar on the server, and the sidebar updates on its own as effects start and end.
What it does
The mod runs on the server and lists each player's active potion effects in the sidebar, hiding itself when no effects are active. Each line can show the effect name, its color, its potency and its remaining duration, and each option is set in a configuration file with a default value. Editing the file and running the reload command applies changes without a restart.
Effect icons can be drawn in two ways. Without Polymer, the sidebar uses colored potion icons. With Polymer installed on the server, the sidebar shows the effect icons used by the game, and vanilla clients see them without a client resource pack, since clients stay vanilla. Polymer support is optional, and the mod also works with a Polymer port in place of the original.
The mod runs on a dedicated server, a single-player world or an integrated server. Clients need the mod as well, which is what the author notes say. Sidebar Potion display is open source under the Apache License 2.0 and is published for 1.21.8 only, as Fabric build 1.0.0.
Key features
Sidebar effect list
Active status effects appear in a sidebar that updates automatically and hides itself when the player has none.
Colored and named lines
Lines can show the effect name and be colorized by effect type, which makes the list easier to scan.
Potency and duration
Each line can show the effect amplifier, so a higher potency is visible next to the effect.
Vanilla HUD hiding
An option hides the default potion effect display so only the sidebar remains on screen.
Icon options
Effect icons come from Polymer when installed, or from colored potion icons when it is not, and forceCompatIcons chooses between them.
Modded effects
Effects added by other mods are listed along with the vanilla ones.

How it compares
Polymer Patch for Stacked Blocks is a Fabric mod for 1.21.8, server-side only, under the MIT License, and it is not open source. Ocean's Delight (Polymer Port) is a Fabric mod for 1.21.6 – 1.21.11, server-side only, under the MIT License, and it is open source. Better Potions HUD is a Fabric client mod for 1.21.11 – 26.3, client-side only, and it is not open source, so it puts a potion list on each player's screen instead of the server.
