It supports online sessions and in-person play without internet, and imports information from Hero Lab and PC Gen. A free Guest License lets a player join when the host has an open guest seat. The Player License is $10 as a one-time purchase; the GM License is $42 as a one-time purchase. It runs on Linux, macOS, and Windows.

Owlbear Rodeo is a browser-based virtual tabletop for running tabletop encounters. Its shared battle map workspace includes maps, tokens, images, drawing, text, and fog tools. Scenes use an infinite canvas with square, hexagonal, or isometric grids, and can hold multiple maps, images, and drawings. The app runs in a browser without requiring a software download and is responsive across mobile and desktop operating systems. Players can enter a room from a link without an account, request to join, and wait for the game master’s approval. Game masters can set layer permissions for creating, updating, or deleting items and limit character interaction to owners. Extensions add tools such as dice, initiative tracking, character sheets, and dynamic fog; listed integrations connect D&D Beyond and Pixels Dice. The free Nestling plan costs nothing and includes two rooms with random room names and backgrounds. Fledgling and Bestling offer custom room names and backgrounds, with 5GB and 10GB storage respectively; their prices are shown in checkout. Owlbear Rodeo offers campaign tools and API access, but no rules compendium or mobile apps.
