The Foundry VTT software devs create a Year in Review blog annually. Here's the one for 2026:
foundryvtt.com
Starting in 2024, the Year in Review began including usage statistics for game systems. I find these numbers pretty interesting. Please see my notes below on Foundry's userbase. These users do not represent all GMs or players.
2026 Top 20 Game Systems
Dungeons & Dragons Fifth Edition
2024 was Foundry VTT's first year with an official Dungeons & Dragons game system. Because of the extremely recent partnership with D&D, Foundry VTT only has the SRD content + Tasha's/Tomb of Annihilation/Phandelver for the 2014 ruleset, and otherwise focuses on releasing 5.5 books.
Despite this, 2014 and 5.5 usage numbers are combined as "Dungeons & Dragons Fifth Edition". When you download the system, you automatically receive the SRD content for both rulesets.
D&D was installed by 66.5% of users in the 2024 Year in Review, and 64.3% of users in the 2025 Year in Review.

2026 Top 20 Game Systems
The heartbeat of gameplay on Foundry VTT are the exceptional game systems that you, our community of developers, have created for the platform. We have 475 approved game systems on the platform, growth of +30% since this time last year. Of these 475 approved systems, 144 are already advertised as Version 14 compatible.
The following table reports game systems ordered by which were the most-played over the past year, defined as the system used by the game world that had the largest amount of playtime for each user. We also report the percentage of users who have each system installed. The "Change" column is the change in most-played order since this time last year.

Major new systems
- Daggerheart (#9) had a license-based (non-official) implementation added about 9 months ago. Several fanmade implementations existed before that.
- "[The Foundry VTT system] is not associated with Critical Role or Darrington Press, but is made possible thanks to the Darrington Press Community Gaming License."
- Cosmere RPG (#19) was added around 9 months ago.
- Draw Steel (#27) was added around 14 months ago.
Notes on FoundryVTT if you are unfamiliar with the software
- "Users" are people who paid $50 to buy the Foundry VTT software, so primarily GMs. Players join through a browser and do not download any software.
- Foundry VTT is an extremely complex software with a steep learning curve. Owlbear Rodeo or DNDB Maps it is not.
- Foundry does have a 30-day refund policy, so if someone still owns the software they probably navigated their way through the early stages of learning to use it.
- A specific user number is not given, but "Foundry VTT has a lot of users, so even a fraction of a percentage point represents a significant number of people for whom each of these game systems is their absolute favorite!"
- Foundry VTT does not support mobile platforms at this time.
- Some add-ons can make battlemaps usable for in-person games, but I would not be shocked if the majority of Foundry games are played entirely online.
- The typical Foundry user does not purchase any premium content such as the D&D 5.5 PHB ("the typical (median) user has 1 game system installed, 19 modules installed, and does not own any premium content").
- Modules are unofficial add-ons. A popular one is Dice So Nice, which adds 3D dice to the screen. Some modules must be purchased or require Patreon subscriptions, but most are free.
