Tarrasque.io v0.31.0: See Online Players & Custom Grid Distance

New update with a couple of small new features to help smoothen out your next session. Enjoy!

What's New:

  • You can now see online players in the Chat panel and the dashboard! The Chat shows players as online only if they are on the same map you are, so that's a good way to know if you're all looking at the same thing!

  • Custom grid distance and units. 10 ft maps? Prefer metres instead of feet? Not a problem. Works with the Measure tool. Also, a new grid settings design!

Bug fixes:

  • Fixed a bug with the grid not updating on map switch or when manually edited.

Tarrasque.io v0.30.1

Hi everyone! This update brings a couple of improvements to the new Measure tool, some performance improvements, and a new subreddit! Enjoy!

What's New:

  • Tarrasque.io Subreddit. Get your Tarrasque.io news directly from the place where you likely heard about Tarrasque.io! Post tips & tricks, send feedback, start DM conversations, share battle maps, or anything else you can think of! https://www.reddit.com/r/tarrasqueio
  • Distance will now be automatically measured while dragging a token!


  • The measure tool label now scales based on your zoom level so that you can still measure distances when fully zoomed out.

Bug fixes:

  • Fixed a bug with CPU usage while in combat relating to the active combatant animation, things should be a bit smoother now!
  • Fixed an issue where token handles would stay behind for a couple of seconds before moving to the new location.
  • Changing the grid settings will no longer freeze your device. There's now a slight delay to the inputs to avoid rerendering the grid while typing.

Tarrasque.io v0.30.0: Measure Distance & Bring to Front/Send to Back

Today's update brings THE most highly requested feature: distance measuring! Also, as promised, bring to front/send to back. Enjoy!

What's New:

  • Measure distances. Well this was a long time coming. You can now measure distances using the brand new Measure tool on your top-left corner Toolbar. This doesn't take into account diagonals yet as there are a few different preferences to implement (5, 7, 5-10-5, etc.), but that will be coming soon!

  • Bring to front/Send to back. No more losing tokens behind other tokens. You and your players can now reorder creatures on the map so that they appear in front or behind other tokens.


  • The email address for your account can now be found in the User Settings dialog.

Bug fixes:

  • Fixed a bug where you couldn't add creatures to the combat if you had first added an Object Token.
  • Fixed an issue with the cache still listening to changes on a previously-visited battle map.

Tarrasque.io v0.29.0: Object Tokens & Hide Monster Names

This week's update brings two heavily-requested features, more control over token overlays, and a few bug fixes! Enjoy!

What's New:

  • Object tokens. You can now add tokens for furniture, props, and other assets that require a token to be visualized on the map, but don't have a stat block attached to them!

As with Adventurers and Monsters, you can drag and drop these onto your map or click the "Add to Map" icon to create an object token.

  • Campaign settings for creatures are now split by creature type, which means you can now show HP bars and nameplates for adventurers but not for monsters!

  • Hide Monster Names. As shown on the screenshot above, there's a new entry in the campaign settings, which, when unchecked, will allow you to hide monster names from players in the Combat Tracker!


  • Tooltips are now light in Light Mode!

  • Changed the Shape tool icon to be more consistent with the rest of the UI.

  • The Adventurers, Monsters, and Objects panels are now disabled for players if there's no token in those categories that they can control.

Bug fixes:

  • Fixed a bug where you couldn't post to Chat until a dice roll was triggered first.
  • Fixed a bug where the token toolbar would remain visible after deleting the selected token(s).
  • Fixed issues with emails ending up in spam.

Tarrasque.io v0.28.2

Hi everyone! This update brings more player permissions, more streamlined Campaign Settings and Share modals, chat notifications, and more. Enjoy!


  • Added permissions for forbidding players to use the Draw tool and the Shape tool. No more unwanted distractions while trying to describe a scene. Also, reorganized the Campaign Settings to flow better.

  • You can now differentiate between sharing a map publicly and sharing it just with players. It should also be a bit clearer now that players don't enter a password to join a map.

  • You can now click the icon next to the battle map name on the dashboard to open the Share modal. Also, it's a bit more informative when you mouse-over it.

  • Added a chat notification bubble to let you know when someone posted a message or rolled some dice!

  • The Dice Roller now closes when you hit Escape 🎉

Bug fixes:

  • Fixed a bug with search results not being ordered correctly.
  • Fixed an issue with the Reveal tool keyboard shortcut not working in Chrome.

Tarrasque.io v0.28.1

Today's update has a few changes to make your experience a little bit smoother and ease the learning curve for new users. Also, Terry merch! Enjoy!

What's New:

  • New helpdesk! All articles have been updated to take into consideration new features. I've also merged a bunch of articles to make it easier to navigate the helpdesk and added tips & tricks on how to use each feature.

  • New merch! You can now get Terry the Tarrasque shirts, mugs, and stickers!

  • New status page! This will let you know if something is going on that's affecting Tarrasque.io.

  • Live Help. Found a bug or had an idea in the middle of the session? Or just wondering how to do something? Don't put it off for later - let me know right away. I may even give DM advice if you'd like 😁


  • You can now change campaign settings from the battle map - no need to go back to the dashboard. This is more in-line with how Combat Settings used to work, but is global for all maps of a campaign.

  • The previous update made it so that players needed to wait their turn before being able to move their assigned tokens. As some of you prefer more flexibility, this has now been turned into a Campaign Settings option. Freedom of Movement is now turned on by default. If you'd like to restrict movement based on turn order, simply disable this in your Campaign Settings.

Tarrasque.io v0.28.0: Player Controls

Hi everyone! 👋 Lots more player functionality to take the load off your hands in this release! Enjoy!

What's new:

  • Players can now draw lines and shapes with the Draw tool and the Shape tool respectively! That's less work for you as a DM!
  • When in combat, players will now only be able to move their tokens if it's their turn. It's still free-range when out of combat.
  • Also, players can now edit the HP of creatures they control directly from the Combat Tracker!

  • You can now choose to share an individual dice roll to chat without committing to sharing all of your dice rolls.

  • Chat history can now be deleted. To do that, just click the icon at the top right of the Chat panel.


  • Updated the keyboard & mouse shortcuts overlay for players since they now have access to more options!
  • Changed the way that the Draw tool eraser works - it should now behave more reliably for removing drawn lines.

Bug fixes:

  • Fixed an issue with chat messages appearing in the wrong order after a refresh.

Tarrasque.io v0.27.0: Public Dice Roll Sharing & Chat

Hi everyone! Today's release brings the long-awaited public dice rolls, a chat system, a few more QoL improvements, and a couple of bug-fixes. Enjoy!

What's new:

  • Public dice roll sharing & Chat. Now everyone can see who rolled what and when! And you can now chat with your friends straight from Tarrasque.io! The chat is campaign-wide, and as such will persist when you switch between maps.

  • Show GM Dice Rolls to players. Fudging rolls is a thing, so this is off by default, but I know a lot of you are huge believers in sharing your rolls with your players. Simply toggle on this feature in your campaign settings and you're good to go!


  • The chat panel listens to the keybind "C", which was previously used by the Combat Tracker. The Combat Tracker will from now on listen to "T".
  • The search field is now automatically focused when you open a panel, in order to make it easier to find what you're looking for! (you can press Escape to quickly unfocus the search field)

  • Navigation and panels are now slightly faded so that they don't completely cover what's going on behind them on the map.
  • The combat tracker header is now always shown in Player and Present views.
  • Added icons in the keyboard/mouse shortcuts.

Bug fixes:

  • Fixed an issue where searching for battle maps in the app would also show you maps from other campaigns.
  • Fixed a bug where clearing all the shapes on a map would allow you to undo the action but not redo it.

Tarrasque.io v0.26.0: New Colors, Terry, & QoL Improvements

Hi there! I'm about to start work on dice roll sharing, but before I do, here's a new quality-of-life update! Enjoy!

What's New:

  • New colour scheme and fonts. A whole new set of dark mode and light mode colours. The text should be more visible now in both modes, and there are a couple of new fonts to give the app a more distinct look! Also, dark mode is darker, and light mode doesn't burn your eyes out anymore.
  • Terry the Tarrasque is here! Finally have a logo that isn't just text! Terry was initially a command-line tool I wrote to help me do some admin tasks, so I'm glad he gets to be seen for his contributions! 😂


  • Made the colour picker faster, and updated its interface to be more minimalistic. Also, added some commonly-used colours at the bottom - you'll be able to customize these soon!

  • You can now switch between Draw tool brush and erase modes by tapping its hotkey (4), much like you can with the Shape tool.
  • Made the "Clear All" icon different from the "Delete" icon so that it's clearer that this action will delete all shapes/drawings.
  • When hovering over a Fog of War resize handle, your mouse cursor will now switch to the Resize cursor to indicate that you can drag the circle to resize. This should alleviate issues where you might accidentally move a FoW area.
  • Token markers can be hovered while using the Pan tool. Now you don't have to switch to the Select tool to hover (or attempt to memorize) every icon to know what it means!
  • Made the stat block opaque for consistency with the rest of the UI.
  • Removed the ability to change the background of a token that uses an image. It had no effect anyway! The feature still remains for tokens without an image.

Bug fixes:

  • Fixed a bug where drawn shapes would start at the top left corner of the closest square. They should now start at the corner closest to your mouse cursor.
  • Fixed a bug where drawing a circle by dragging to the left didn't work as expected.

Tarrasque.io v0.25.0: Snap to Grid for Area of Effect

Snap to grid and resizing for shapes is finally here! I swear this feature took longer than multiplayer to implement 🤯️. I hate maths 😁️. Enjoy!

New features:

  • Snap to Grid for Area of Effect. New shapes will now automatically snap to the grid when drawn!

  • Resize Shapes. You can now finally resize circles and rectangles! Triangle resizing should be coming in the next update too :)
  • Mobile Web App. Tarrasque.io can now be installed on your phone or tablet! Open Tarrasque.io on your browser, click the browser menu icon, and click "Add to Home Screen". This will add a shortcut to your home screen that will launch Tarrasque.io as a standalone app!


  • Shapes can now be selected and moved using the Select tool as opposed to the Shape tool. The Shape tool is reserved for just drawing shapes.
  • You can now draw a shape inside another shape since the Shape tool doesn't select underlying shapes.
  • After drawing a shape, you'll automatically be switched to the Select tool so that you can continue with selecting it.
  • You can now draw Fog of War areas and Area of Effect shapes outside the map boundaries. This should help with hiding areas more easily and not needing to draw shapes elsewhere before moving them where you want.

Bug fixes:

  • Fixed a bug with the request timing out when importing monsters and spells via JSON/XML.
