DexArcana

DexArcana is a set of free browser tools for Dungeon Masters, so there's nothing to install. Its Dungeon Master Screen keeps turn order, fog, dice rolls, notes and cue cards on one page during a session, and players don't see the Dungeon Master's notes. The screen also has a dice tray with d4 to d100, plus advantage and disadvantage on the d20, and encounter tables under Extras: roll one and the monster or NPC drops straight onto the open map. A soundboard and ambience layers are there too. The map builder lets a Dungeon Master lay down floors, walls, furniture and lighting to make a battle map without drawing skills. Fog and lights decide what players see, and maps can be exported as PNG or JSON. The world notebook links lore entries so places, people and factions stay connected. Players join from their own Player Screen, where they keep their sheet, the party list, chat and dice. Players need a free account to join. Every tool is free on every plan. Paid plans only add saving space: Dungeon Master is $5 a month and Guild is $12 a month. The free plan needs no card. It works for in-person tables using a second screen and for online games.
