Track everything in a D&D encounter — initiative, HP, conditions, lair actions, legendary resistances and spell slots. Supports 5e and D&D 2024 rules. No download, no account.
What is it
A D&D encounter tracker is a digital tool that replaces the paper, spreadsheets, and sticky notes a DM uses to run combat.
An encounter tracker keeps initiative order, tracks each combatant's HP, manages conditions that expire after a set number of rounds, and handles special mechanics like lair actions and legendary resistances — all in one interface.
Combat Companion is a free encounter tracker that runs in your browser. It supports D&D 5e (2014) and D&D 2024 rules. No virtual tabletop, no maps — just the mechanical tracking a DM needs mid-fight.
Everything saves automatically to your browser. Reload the page and your encounter is still there. Bookmark it on your phone for quick access at the table. Free forever for all core encounter tracking features.
