Tarrasque.io v0.33.0: Temporary HP, Quick Token Actions & Diagonal Measurements

Yet another packed update! Lots of new features and improvements, as well as some more quality-of-life updates. Enjoy!

What's New:

  • Temporary HP. Well, this has been a long time coming. Temp HP is now a thing, and persists across maps for adventurers! Also, you can no longer heal a creature to more than its maximum HP or damage it beyond 0 HP. Dead is dead!

  • Quick Token Actions. You can now change the HP and markers of a creature directly from its token without having to right-click it or go to the Combat Tracker!

  • Out of Combat HP. You can now see (and edit!) the HP of any creature, regardless if it's in combat, simply by clicking on it to reveal its HP bar and the Quick Actions.

  • Diagonal Measurements. The PHB, the DMG, and Euclid walk (diagonally) into a bar. You decide how diagonal movements should be measured now. Oh, and this works with chained measurements as well (right-click while measuring).

  • Persistent Token HP. Tokens now remember their HP in and out of combat. No more accidentally resurrecting creatures when finishing combat.
  • Persistent Token Counter. When adding 3 goblins to combat, and removing the 1st, the remaining goblins would have their top-right creature counters updated to match the new order. This led to confusion because what was once Goblin 2 is now Goblin 1. No more of that - tokens now remember their number until the last token of that creature has been removed from combat.
  • Combat Reset has a new home. Since tokens now remember their HP, there's no reason not to use this to quickly reset combat! This will ask for a confirmation before proceeding so don't be afraid to test it out!


  • Grid settings have been merged under one button to make them a bit simpler to use. Also, some inputs are hidden when Snap to Grid or Visible are unchecked so as not to overwhelm you with fields that you don't need to fill out!

  • Added missing Cancel buttons to some confirmation modals.
  • Changed the measurement indicator to appear higher when moved using touch to avoid being covered by the dragging finger.
  • Lots of general performance improvements, especially relating to combat and the Measure tool!

Bug fixes:

  • Fixed a bug with monster and object tokens not updating their images in real-time when their respective assets change.
  • Fixed issue with grid getting temporarily misaligned when making changes to the grid.
  • Fixed an issue with tokens becoming unbound when right-clicking on them during a drag operation.
  • Fixed a bug that allowed players to delete their assigned tokens using the keyboard shortcut.

Tarrasque.io v0.32.0: Chain Measurements, Custom Markers, Shape Ruler & Player Spells

Well, this is one of the most packed updates in a while. Enjoy!

What's New:

  • Chain measurements. You can now cut through corners and chain measurements together by right-clicking on the map while using the Measure tool.

  • Measure tool for shapes. Shapes have never been easier to draw on a grid. All shapes now automatically measure the draw distance for you while being created.

  • Custom markers. There are a ton more markers available now, which should cover most use-cases. And if not, well, you can now create your own markers!

  • Player Spellbooks. Players now have their own spellbooks to create and import their favourite spells into! I never wanna hear the phrase "what does my spell do?" again.


  • Token bar and token menu have been merged. Token actions were split between two places and it felt clunky, so now all your token controls are available by right-clicking on a token. Also, it's a tad bit more organized now.

  • Merged Hide and Reveal tools. Speaking of being organized, the Hide and Reveal tools have now been merged into one Fog tool. As with the Draw and Shape tools, you can switch between different modes (Hide and Reveal) from the action bar, by clicking on the Fog tool icon, or by tapping the hotkey (3).

  • Battle Map Quick Icons. I've listened to your feedback about the Share & Present actions being too important to be hidden in a menu, and I'm here to make amends. The in-app battle maps panel now features quick icons under the battle map name to allow you to be as productive as possible!

  • Info buttons. As you can see from the panel screenshot above, nearly every panel and dialog now has an Info button attached to it. Clicking this will open up the appropriate Helpdesk article for that panel, to help you get the most out of the app.

Bug fixes:

  • Scaling handles. If you've ever uploaded a map that's under 1000x1000px, you've probably come across the issue where resize and rotate handles for tokens, shapes, and Fog of War, as well as the Measure tool popups, were far too big. Well, no more. Everything should scale properly now depending on map dimensions and zoom level. I'm genuinely more happy about this than I am about anything else in this changelog!
  • Fixed a bug with dice notations that had a +0 modifier not being recognized as valid dice notations.
  • Fixed marker placement on tokens when combat is inactive.
  • Fixed the size of the shown dice notation while rolling dice. It was smol.
  • Fixed a bug where you couldn't mouseover the "+3" markers notation with the Pan tool to show the marker tooltips.

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 v0.28.0: 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.
