   Fluxer vs Stoat Chat Comments

   Positive comment by 4thy · May 24, 2026

   Stoat has a Discord-like appearance but Fluxer's UI has been built to immitate Discord almost 1:1, down to the last detail. (Even the way the Settings menu is formatted)

   The UI is nearly indistinguishable so it's immediately familiar and using it is effortless for Discord users since there's literally zero friction.

   You can also import Server Templates from Discord and it will automatically add Channels/Categories/Roles.
