Tabletop gaming has developed a robust ecosystem of digital tools — virtual tabletops for online play, character builders that automate the math, scheduling apps for coordinating groups, and community platforms that keep gaming groups connected between sessions. These tools don't replace the table but they extend the hobby into the spaces between gaming sessions and make it more accessible when physical gathering isn't possible.
Virtual Tabletops
Roll20 is the most widely used virtual tabletop — free tier is functional for most games, plus subscription adds features. It has the largest player base and the most published content available as integrated modules. Good for: D&D and Pathfinder with official content, pickup games through the LFG system, groups who primarily use VTT for maps and dice.
Foundry VTT is a one-time purchase ($50) that runs on your own computer or a hosting service. More powerful than Roll20 with better performance and a passionate modding community that has created free systems for hundreds of games. Good for: groups that want the best VTT experience and are willing to do some setup. The Foundry community is extremely active with free modules for almost every major RPG system.
Fantasy Grounds Unity is the premium option with the most integrated official content for D&D and Pathfinder specifically. More expensive than alternatives but the most polished experience for D&D specifically.
Character Building Tools
D&D Beyond is the official D&D 5e character builder and rules reference — subscription unlocks the full rules, free tier covers the basics. The mobile app is useful at the table. Digital sourcebook purchases on DDB are tied to your account and accessible anywhere.
Pathbuilder 2e (mobile app) is the standard Pathfinder 2e character builder for most players. Free, comprehensive, and updated regularly as new content releases.
Archives of Nethys has the complete Pathfinder 2e rules for free in a searchable format — the Paizo-sanctioned rules reference that most Pathfinder players use.
Scheduling and Group Management
When2meet is the simplest scheduling tool — share a link, everyone marks their availability, see the overlap. Works for finding game sessions across complex schedules. Doodle is more feature-rich but similarly functional. Discord is the primary community platform for most gaming groups — channels, voice chat, scheduling bots, dice bots, and the persistent community infrastructure that helps groups stay connected.
Board Gaming Digital Tools
Board Game Arena is the leading browser-based board gaming platform with a library of 600+ games playable online. Free tier has most content; premium subscription adds more games and features. Excellent for learning games before buying them physically.
Tabletop Simulator (Steam, ~$20) provides a physics sandbox with thousands of fan-created game implementations available through the Steam Workshop. Flexible but requires more setup than BGA.
BoardGameGeek (BGG) is the definitive board game database, review aggregator, and community forum. The BGG app and website are the standard reference for game selection, ratings, rules questions, and community discussion.
