The Commons
Updated July 2026
The Commons is where players and GMs share homebrew content with each other — individual Compendium entries, or a whole campaign packaged up for someone else to run.
Getting here
Open the Community tab and switch to the Commons wing (Boards is the other wing — that's for finding a table to play at, a separate feature). You'll see a "New from creators you follow" rail up top, your own published works and installs below it, and a Browse the Commons entry into the full catalogue. You can also reach browsing from any Compendium screen's own Browse the Commons footer link.
Browsing and installing
The browse screen has search, filters by type and system, and three sort chips: Top (most installed), Newest, and Updated.
Tap any listing to open its detail page — the creator's name (tap it for their creator page), a pitch line, what's inside, and an Install button.
Installing copies the listing's contents into your own Compendium (or, for a campaign pack, creates a new campaign in your GM library — see below). What happens when you tap Install depends on how much room you have left:
- Room to spare — installs immediately.
- Right at your cap — you'll see how many entries this install adds and what you'd hold afterward, with a chance to confirm before it goes through. You get exactly one install past your limit; after that, new installs pause until you're back under.
- Already over your cap — blocked. You'll see exactly how many entries you're holding against your limit, and your options: make room, reset to your system's base entries, or go Pro.
Entries you hold past your cap are never deleted — they just become read-only until you're back under your limit.
Publishing your own work
Open any Compendium entry you own and tap Share to the Commons — or start fresh from the Commons screen's own publish button. Pick which of your entries to bundle in (one or several), write a title and a one-line pitch, and confirm the attestation checkbox: "This is my own work — it doesn't reproduce published rules text." You can't publish without checking it.
Free accounts can have 3 live listings at a time — a note on the composer shows how many of your three you're using.
Once published, your listing appears on the browse screen and shows a from the Commons tag on the entries it came from wherever they appear in your own Compendium.
Publishing a campaign pack (Pro)
From a campaign's own detail screen, look for The Commons section — it opens the same publish composer, pre-loaded with that campaign's snapshot (name, system, level) instead of individual entries. You can still optionally bundle Compendium entries into the pack alongside it, or publish the campaign's primer on its own with nothing attached.
Publishing a pack needs Pro. Installing one is free for everyone — Free-tier players and GMs can install any pack a Pro creator publishes.
If your campaign has a GM secret written into its primer, publishing a pack asks you to separately confirm you understand the secret becomes public along with everything else — packs don't have a way to keep part of a campaign private.
Installing a pack creates a brand-new campaign in your own GM library, primer and secret intact, plus any bundled entries in your Compendium. You'll need GM mode enabled to install one.
Following creators and their work
Every listing's author name opens a creator page — their track record, a Follow button, and a shelf of everything else they've published. Follow a creator and their new work shows up in your "New from creators you follow" rail without you having to go looking for it.
Keeping up with updates
If a creator republishes something you've installed, you'll see a small amber dot on that entry in your Compendium, and an Updates filter chip appears if you have any pending. Open the entry to see the creator's own note on what changed, then choose:
- Update — replace mine — takes the new version. Any changes you'd made to your own copy are lost, so this asks you to confirm first.
- keep mine — dismisses the dot for this version only. The next version the creator publishes will knock again.
Campaign packs don't have an update path — a pack you've installed stays exactly as it was installed.
Reporting or blocking
Both a listing and its creator have a Report option, reached from the overflow menu on their respective screens. Reporting a listing flags the content itself (including a specific option for "reproduces published rules text"); reporting a user flags the person. You can also block a creator from their creator page if you'd rather not see their work at all.
