EasyPortal

Portal frames are drawn on a grid in the Portal Designer, with left-click to paint and right-click to erase, and click-and-drag works for filling larger areas. The block palette is taken from the player's own inventory, and a frame material is chosen from it. A reset button clears the canvas for a fresh start. A player walks into a finished portal gateway and is teleported automatically, since the mod detects the position and triggers the jump.

Portals can be one-way, pointing at a saved coordinate, or bidirectional, connecting two portals so travel works both ways. A 1:1 linking rule lets each portal pair with only one other portal at a time, while multi-linking is allowed across the network. The destination is resolved from the portal's name, so coordinates are worked out without manual entry. A block requirement screen on the HUD shows what a portal still needs compared with what is in the inventory, and survival play requires those blocks to be gathered first.

The mod runs on the client and on the server, so both sides need it. It is for Fabric on Minecraft 1.21.1 only, and the code is under All rights reserved, so it is not open source. A Portal Network Dashboard lists, searches, deletes and creates portals, and a configuration file named easyportal.json sets the portal limit per player, claim protection and periodic frame checks.
