D20PRO vs TaleSpire

D20PRO is a multiplayer virtual tabletop for role-playing games, with automated play tools and controls that leave the Game Master able to approve or delay actions, adjust rules, and create scripts. It supports D&D 5E, 3.5 and 4th Edition, Pathfinder, and Starfinder, and can be extended to other systems. Combat automation covers attacks, damage, ongoing effects, initiative, movement, saving throws, checks, and area effects. Maps support fog of war, hidden areas, distance and line-of-sight measurement, map libraries, and drawing from images. Game Masters can share private notes and files as handouts. 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.

TaleSpire is an online tabletop for playing pen-and-paper role-playing games with friends. Game Masters and players can construct and revise campaign boards as a session unfolds, with updates synchronized in real time. The core game does not prescribe a ruleset; it is designed for games played on a square grid with standard seven-set RPG dice. Tools include dice, rulers, area markers and emotes, as well as modes for turn-based combat and cinematic sequences. Up to 16 players can be online in a campaign, and multiple players can receive Game Master privileges to build together. Players can browse and upload slabs through in-game mod.io, and share creations through TalesBazaar and TalesTavern. Symbiotes can interact with the game through an API. The free Guest Edition lets users join a campaign when a one-time seat is available, even if its owner is offline; guests cannot create campaigns or buy seats. The full game costs $24.99, paid once, with no subscription for the base game or server access. Official support covers Windows and Apple Silicon macOS; Linux works under Proton 7 and later but is not fully supported.
