Frameless

The Frameless mod unlocks new decorative possibilities in Minecraft by allowing you to create invisible item frames. To activate this feature, simply hit a regular item frame with a glass pane.

One of the key advantages of this mod is its server compatibility. You can install Frameless only on the server, and it will work even with clients using the vanilla version of Minecraft without mods. This is especially convenient for multiplayer servers.

The resource usage mechanics are also well thought out. Players in creative mode don't consume glass panes when creating invisible frames, which follows standard item consumption logic. When an invisible frame is broken, the glass pane automatically returns to the player's inventory.
