What Digital D20 is
Digital D20 is a free framework for creating linked role-playing game modules and a virtual tabletop. Its authoring framework connects rules, maps, and scenes, and the maker’s repository points to Twine for building RPG adventures. The adventure directory includes a free option for custom adventures in English and Spanish. The virtual tabletop lets users create or continue a room. A Chrome extension can connect a D&D Beyond character sheet, roll dice for D&D Beyond monsters, and show their stats. Users can add links to their own music and sound effects, with Tabletop Audio recommended. The board page suggests using Zoom, Discord, Skype, or Google Duo for conferencing. Digital D20 runs on the web and has Android and iOS apps. The VTT is a Node project that can be self-hosted; its repository says 99% of code runs locally while the server sends messages to people using the same URL. Both projects are described as free software, with a GPL-3.0 repository license.
