Campaign wiki and rules engine
Write your world in a wiki where you choose, paragraph by paragraph, which player sees what. Run the game on a rules engine that handles spells, conditions and combat at the table. The DM pays one subscription and the players join free.
The demo is a real campaign and needs no account. The trial runs 14 days and needs no card.
Every screenshot below comes from the public demo, and every link opens that demo. You do not need an account to look around.
Most campaign wikis hide whole pages or keep one DM-only block. In Hearthmoot you address any paragraph to any single player, right in the text.
One page can hold what everyone knows, a note only the rogue has found, and a section you wrote weeks ago and have not revealed yet. Each player reads the same page and sees their own part of it. When the story catches up, you change who can see that paragraph.
Character sheets run on a rules engine. Spell slots, conditions, item effects and rests work themselves out, so nobody stops the scene to do arithmetic.
Each campaign starts from the 2014 or the 2024 rules and then takes your table’s decisions on board.
Start from the 2014 or the 2024 rules, and switch later if the table changes its mind.
Offer the 2024 Fighter next to the 2014 Ranger in the same campaign.
Override a single rule inside the edition you picked and keep everything else as written.
Off, warn or block. A spell with a costly component needs it in the character’s inventory, and a component the spell consumes is removed when it is cast.
Build an encounter from your actual party and run it five hundred times before the session, so you know the odds before you commit to it.
On the night, the tracker runs initiative, damage and conditions, and each player follows the fight from their own screen.
When a player can react, their screen asks them, with a countdown you set.
Four ways to count critical damage, from rolling the dice twice to taking the maximum.
Set the difficulty and decide who sees the rolls: the whole table, only you, or the player.
Players can see a monster as Bruised, Hurt or Dying while you keep the numbers.
The campaign runs on an in-world calendar you design, and the rest of the system reads it.
When you move the clock forward, spell effects and conditions run out on time. When you call dawn, abilities that recharge at dawn come back and injuries heal another day. Shops restock on the same calendar.
Months, weekdays, moons and festivals, including festivals that fall on a full moon.
Advance by hours, days or weeks, and see which festivals you are about to skip. Dawn and dusk are their own step, so recharges happen when you say the sun is up.
Stock a shop by hand or generate one: a blacksmith, an alchemist, a general store or a curiosity shop, at four levels of wealth.
Sell to a character at a price you can adjust on the spot, buy their loot back, or have a shop scribe a spell for a wizard.
Every campaign starts with the free 2024 and 2014 rulebooks installed: 339 and 319 spells, 330 and 317 monsters, 443 and 437 items.
Material from books you own, and everything you invent, you enter through the Create forms: spells, items, monsters, feats, subclasses, species, backgrounds, conditions, loot tables and calendars. A content pack installs whole, and installing one never overwrites a page you have changed.
Most tables keep their world in one app and their character sheets in another, and the calendar, the shop prices and the loot end up in a notebook. Hearthmoot holds all of it in one campaign, for one subscription.
or €110 a year, two months free.
Tax included. This is the price charged in the country you pick.
14 days free, no card needed. When the trial ends nothing is deleted: subscribe and your campaign comes straight back. There is no free tier.
Add-ons are billed per campaign on the same subscription and the same cycle as the plan.
If you ever leave
When a subscription ends, for any reason, this is what happens to your campaign:
Paid period ends
The campaign stops running. Nothing is deleted, and a payment brings it straight back.
Until day 30
Your full export, every page plus the campaign database, stays one click away on your account page.
Day 60
The campaign is deleted from our live systems. This cannot be undone.
Day 90
It is gone from the backups too, and the key that encrypted them is destroyed.
No. The DM’s subscription covers the whole table: six players, or twelve with the larger-table add-on. A player joins with a name and a passcode you give them, and needs no account or email address.
Yes, by moving the content over yourself. There is no import from other sites. If your notes are digital, copying and pasting them into pages is the quickest route; the Create forms take spells, items, monsters and the rest one at a time.
Nothing to install. Hearthmoot runs in the browser, on a computer, a tablet or a phone, for you and for your players.
Yes, by entering it yourself: type it or paste it into the Create forms or into a page. Hearthmoot does not import from other services. The 2024 and 2014 open rulebooks come installed, so the common spells, monsters and items are already there.
Only you and the players you let in. Each campaign is private on its own address, and inside it every player sees only the parts of a page you have shown them.
Yes. The demo is a real campaign called Emberwick, running on the real product, with no account and nothing to fill in. You can read it as the DM or as either of its two players and see what each of them is shown. It is read-only and resets every night.
Yes, at any time and from your account page. You get every page you wrote as text files, which open in any editor, plus a full export of the campaign’s database.
You keep your work. The export above is yours to take at any time, and the pages are plain text files that open without Hearthmoot. Take a copy whenever you like; it costs nothing.
On servers in Europe. Nothing you write is used to train AI.
Backups run automatically. None is kept for longer than ninety days.
Your campaign stops running at the end of the period you paid for. After that the steps are fixed:
5e- and 5.5e-compatible play. Every campaign comes with the free 2024 and 2014 rulebooks installed (339 and 319 spells, 330 and 317 monsters, 443 and 437 items).
No. There is no battle grid with tokens to move. Hearthmoot holds everything around it: the world, the characters, the rules, the fights and the record of what happened. You can use it next to a virtual tabletop or a physical map.
