Roll20 vs. AI DM: Which Is Right for Your D&D

Roll20 vs. AI DM: Which Is Right for Your D&D

Roll20 is a virtual tabletop (VTT) for groups playing D&D remotely. AI DMs like The Endlessness run D&D for solo players.

They're different categories of product. Here's how to pick.

What Roll20 Is

Roll20 is a VTT platform. You join a "room" with a group (DM + 2-5 players). The DM sets up maps, tokens, and content. Players roll dice in the shared space.

Features:

• Shared virtual tabletop. Map tokens, fog of war, rulers.
• Character sheets. Roll-integrated.
• Voice/video chat. Built-in.
• Marketplace. Official D&D content ($20-40 per adventure).
• Free tier: Basic functionality.
• Paid tiers: $5-15/month for extra features.

Roll20 facilitates group D&D. It doesn't run the game. You still need a human DM.

What an AI DM Is

An AI DM runs D&D itself. No human DM needed, and no group needed either, though you can bring one: a table here holds two to seven players including the host, and everyone plays a hero.

Features (for The Endlessness specifically):

• Full SRD 5.2.1 rules enforcement.
• 12 classes, 9 species, 339 spells.
• Initiative and combat tracking.
• Persistent world state.
• Pre-built and sandbox campaigns.
• Free tier. Paid tiers for expanded capacity.

AI DMs enable solo D&D, and they also run the game for a group when nobody in it wants to be the DM. What they don't replace is a good human DM you already have.

When to Use Roll20

• You have a group.
• You have a DM (or you're the DM).
• You want to play remotely with friends.
• You want shared maps and tokens.
• You enjoy the social aspect of group D&D.

When to Use an AI DM

• You don't have a group.
• You have a group but nobody wants to DM.
• You want to play solo.
• You play at irregular hours.
• Your group can't find an evening and wants to take a turn a day instead.

Cost Comparison

Roll20:

• Free tier available (limited storage, basic features).
• Paid: $5 (Plus), $10 (Pro) per month.
• Official D&D content: $20-40 per adventure.
• Plus a DM who's also paying for content.

The Endlessness:

• Free tier available.
• Paid: $9.99 (Adventurer), $24.99 (Legend) per month.
• All content included.

Total cost for a group on Roll20 (with a Pro DM + $30 adventure) vs. The Endlessness: comparable monthly, but The Endlessness doesn't need a DM paying extra.

Can You Use Both?

Yes. Many players:

• Play group D&D on Roll20 on weekends.
• Play solo on The Endlessness on weeknights.

Different tools for different gaming needs.

What Roll20 Doesn't Do

• Run D&D without a DM.
• Automate rules enforcement (your DM interprets).
• Generate content dynamically.

What The Endlessness Doesn't Do

• Facilitate group D&D sessions.
• Replace the human DM experience for groups.
• Let multiple real players share a campaign (solo for now).

For Different Player Types

Solo player: The Endlessness.

Group player with a DM: Roll20 (or similar VTT).

Group player without a DM: You're stuck. Find a human DM or use an AI DM solo while looking for a group.

DM running a game: Roll20 or Foundry VTT.

The Endlessness Advantages

• Always available (24/7).
• Free tier is a real game, not a demo.
• No scheduling.
• Rules enforced consistently.
• Infinite content.

Roll20 Advantages

• Real friends in real time.
• Shared maps and theater-of-the-mind.
• Social drinking games.
• Community.

Final Takeaway

Roll20 for a group that has a DM. The Endlessness for a group that doesn't, or for playing alone. Use both if you need both.

Try The Endlessness for free if you don't have a group, don't have a DM, or want to play between group sessions. If it's the DM you're missing, our guide to playing with friends when nobody wants to run it is the place to start.
