Tarrasque.io v0.40: Stat Block Links & Selectively Import Monsters/Spells

This update brings the ability to create external links in stat blocks, a better upload experience, and a new way to import individual monsters/spells from large JSON/XML files! Enjoy!

What's new:

  • Stat Block Links. You can now quickly create links to external URLs from a stat block! Next up, links to spells!

  • Selectively Import Monsters/Spells. Gone are the days of manually editing JSON/XML files or importing hundreds of creatures you'll never use. You can now select which monsters and spells to import when uploading a JSON or XML files!


  • Uploading of large files should now be much more reliable and should complete much faster!
  • Imported monsters and spells are now assigned to the active campaign to avoid polluting your global asset library with campaign-specific assets.
  • Images will now only load when they're in view - gotta save those kilobytes!

Bug fixes:

  • Fixed a bug with tokens snapping into a previous position after changing their HP from the Combat Tracker.
  • Fixed a bug with notes not saving properly.
  • Fixed an issue with long map names not wrapping to a new line.
  • Fixed a bug with users being unable to restart a paused subscription due to multiple failed payments.
  • Fixed a bug where the token color picker would sometimes not show after clicking on it.

Tarrasque.io v0.39: Enhanced Stat Block Formatting, Lock Shapes, Bring to Front Fog of War and more!

I've been working on this one for quite a while! This update is full of small high-impact features and improvements - hope you enjoy it!

What's new:

  • New stat block look-and-feel. The stat blocks have been redesigned to better fit with the rest of the app's design.

  • You can now click the Edit icon on the top-right of a stat block to quickly jump into edit mode without having to scroll through the assets list to find it.

  • You can now copy-paste stat block content with its formatting intact - no more manually making text bold/italic after pasting. Oh, and if you're copying text with links, they get pasted too - perfect for linking to spells!

  • You can now rearrange Fog of War polygons to bring them to the front or send them to the back of the FoW layer. This should make it much easier to fix FoW mistakes instead of having to start from scratch.

  • You can now lock shapes in place so that they can no longer be moved or selected until they've been unlocked. Also, you can rearrange them much like Tokens and Fog of War so that one is on top of the other.

  • There's now a "Heading 3" and "Strikethrough" option in the Rich Text Editor.

  • You can now see a creature's image on their stat block!


  • Maps on the dashboard now take up a lot less space to give you the best screen real estate.

  • Dice roll notations will now become automatically highlighted while editing stat blocks to indicate that they will be clickable upon saving.

  • Shapes and drawings can now only be controlled and manipulated by the user who created them or the DM.
  • Adding a token to a map now scales the token according to the map dimensions, even while the grid is disabled. This should fix situations in big maps where newly-dropped tokens were too small to be seen.
  • Changed the background of the app to match the Fog of War color while in Player/Guest view, so that your players don't accidentally metagame by knowing where the map ends and where your fog begins :)

  • Stat blocks can now be edited on mobile and tablet devices without an insane amount of horizontal scrolling.
  • Improved the experience on devices with virtual keyboards. Text fields such as ability scores, HP, and initiative now properly only show numbers as valid input.
  • Removed the light mode option from the app. This was used by less than 0.6% of users and was causing major delays during feature design as I had to design for two viewing modes. So it's gone now! Long live dark mode.
  • The non-square grid warning now appears beneath the columns/rows fields to avoid interrupting your flow.
  • Moving tokens across the grid should feel a little bit more snappy now while also allowing more free-form movement.

Bug fixes:

  • Fixed a bug where you could accidentally show/hide a campaign's map on the dashboard by clicking on the right side of the campaign name text.
  • Fixed a bug which caused double-click to ping location not work while using the Measure Tool.
  • Fixed an issue where the text field content wouldn't be selected when pressing Tab in a stat block to move to the next field.
  • Fixed a bug where token multi-selection wasn't very reliable.
  • Fixed a bug where there would be a delay and a visible jump in values when editing the HP of an adventurer.
  • Fixed an issue where certain window panels would appear behind existing ones and would need to be reopened to become visible.
  • Fixed a bug where the window panels would move to different locations across the screen when the browser window was resized or moved to a different monitor.
  • Fixed an issue where the user image in the Settings dialog wouldn't scale to its full width.
  • Fixed an issue with crashing due to the grid allowing negative numbers.

To all 4000 of you: thank you for being here with me on this journey. Keep the suggestions and feedback coming - let's make the best virtual tabletop out there together :)

Tarrasque.io v0.38: Tutorial and Help Center

Today's update brings a few improvements, bug fixes, a new help center with videos, and, finally, a tutorial on getting started and getting the most out of Tarrasque.io!

What's new:

  • A new Help Center with a lot of new guides, as well as a tutorial to help you get the most out of Tarrasque.io. Also, a few videos with the best practices on aligning the grid, hiding parts of your map, and more!


  • The Circle and Triangle shapes can now be drawn in the middle of a grid square, allowing for effects to target individual creatures or begin from a point that's not an angle.

  • When using a grid with non-square dimensions, you will now get a warning to let you know that this might affect the measurement accuracy.

Bug fixes:

  • Fixed a bug where creatures with low hit dice (e.g. 1d4 - 1) had a chance to enter the map already dead 😂 
  • Fixed an issue where real-time updates didn't kick in when giving control of creatures to players. Your players should now be able to see and control adventurers and monsters they are assigned to.
  • Fixed a bug with the Chat always showing the DM and players as offline. You should now be able to see who's looking at each map!
  • Fixed the messaging on the Manage Plan dialog for canceled subscriptions/failed payments.
  • Fixed a bug with the "Update Payment Details" button sometimes not working.

Tarrasque.io v0.37: UI Customization

The other day I noticed my DM struggling with the toolbar being hidden by the Combat Tracker, and it made me realize how annoying this must be for some of you working on smaller screens. So this is for all you guys. Enjoy!

What's new

  • You can now resize UI panels and move them anywhere you want! No more having to close the Combat Tracker to be able to see the underlying tools, or choosing between showing Chat or the Adventurers panel.

  • Stat blocks are now consistent with the other UI panels, and have their own top bar where you can drag them around from.


  • The Dice Roller will now stay on screen after you have typed in a roll so that you can keep rolling without having to reopen it! You can also drag it around like the other panels, but not resize it.
  • Dice rolls in the chat will now show the full dice breakdown.

  • You can now click anywhere on a stat block to bring it to the front of other stat blocks and panels.
  • The chat text field no longer suggests previously typed entries.
  • The scrollbar is now thicker to make it easier for point-and-click scrollers.
  • Hitting Escape while on the Dice Roller text field will now remove focus from the text field.

Bug fixes

  • Fixed a bug with "Send to Back" requiring a refresh to see the changes.
  • Fixed a bug where the Dice Roller would disappear as soon as you started typing on mobile/tablet.
  • Fixed a UI bug where a long combatant's name would overflow and be hidden behind the Notes and Stat Block buttons.
  • Fixed a bug on mobile where you couldn't click-and-hold a token to bring up its token actions menu.
  • Fixed an issue where the 0 ft distance was being shown when holding a token.
  • Fixed a bug that was causing too many rerenders and causing the app to crash.

Huge thanks to Prodigy for being an awesome test subject and unknowingly giving me feature ideas! 😁

Tarrasque.io v0.36: More Player Controls & Quality of Life fixes

Lots of fixes and improvements in this update, plus a few more things to give more control to the players and ease the load on the DM. Enjoy!

What's new:

  • Players can now add their controlled creatures to the map! This works just like on the DM side, either through drag-and-drop or by clicking the Add to Map button.

  • Players can now see and control their hidden tokens, as well as hide or show them themselves! Previously, if a token was hidden, only the DM could manipulate it regardless of who else had access to it.

  • Added a new chain icon for map privacy settings, for when a map is shared by link but not visible in the players' dashboards.

  • You can now select a token on the map by clicking the respective combatant on the Combat Tracker.
  • Your group will now be notified when viewing a map without being signed in so that they can log in to control tokens. Also, the sign-in page now redirects you to the last place you were trying to access before signing in.


  • Campaigns now automatically update on your dashboard when you're added or removed from one.
  • Setting a creature alignment's in a stat block is now optional.
  • For maps that are only shared by link, the battle map name is no longer shown in the browser title to avoid metagaming. Instead, the campaign name is shown.
  • Combat Tracker will no longer scroll to a combatant when it's being highlighted or selected to avoid annoyances with things scrolling unnecessarily!
  • When the DM disables the Draw tool or Shape tool from campaign settings, players that are currently using the tool will be forcefully switched away from it.
  • Changing the total grid dimensions no longer messes with the square dimensions or column/row count.
  • Added more Adventurer races to the multi-select field.

Bug fixes:

  • Fixed a bug where importing a monster whose name is partly owned by another monster, would also import that monster.

  • Fixed an issue where certain touch gestures were being overridden on Windows tablets, causing you to accidentally swipe back to the previous page.
  • Fixed a bug where the leading 0 would remain when changing a numeric field like a combatant's initiative or HP.

  • Fixed an issue where the app would crash if you used a 0d0 dice notation.
  • Fixed a bug where users who switched from Titan to Standard would have a limited number of battle maps.
  • Fixed a display bug with the movement measurer being displayed after deselecting a token.
  • Fixed some browser bugs with the rich text editor.
  • Fixed an issue where you'd be switched to the Select tool after using the middle mouse button to pan the map, even though you had the Pan tool selected previously.
  • Fixed an issue where tokens would bug out when right-clicking them during movement.

Tarrasque.io v0.35.1

A warm welcome to the 1200+ DMs who signed up to Tarrasque.io for the Open Beta! Here's the first round of improvements and bug fixes from your feedback. Enjoy!


  • Moved the Dashboard button from the Battle Maps panel to the bottom bar of the app so that it's easier to get to!

  • Added a close (X) button to the top right of every surface.

  • Changed the look & feel of dialogs and panels for easier identification of actions and content through darker shades.

  • Moved the round information in the Combat Tracker under the combat controls so that it's more visible when hovering over the buttons.
  • Added a confirmation dialog to the Roll Initiative button on the Combat Tracker so you don't accidentally reroll initiative for everyone mid-combat. Also moved the Reset Combat button to the top as it's not one of the main combat controls.
  • Player email addresses now get partially hidden after a user joins a campaign for privacy reasons.

  • Merged first name and last name into a single "name" field for privacy reasons. No more last name requirement if you don't feel like it!
  • Changed login session expiry from 7 to 15 days so that your group doesn't get logged out mid-session!
  • Added the Note tool to the Keyboard Shortcuts.
  • Change submit button wording from "Edit" to "Save" in update modals.

Bug fixes:

  • Fixed a bug where the autocomplete input would not auto-select the first entry, and required you to manually select it before adding it to the list.
  • Fixed a bug where error messages wouldn't show up when editing a stat block, thus making it impossible to save when there were errors.

  • Fixed an issue with messages in chat that have special characters not rendering correctly.

  • Fixed a bug where the app would pop up with a warning that said you were reconnecting to the server every few minutes, even though no disconnection had happened.
  • Fixed an issue where an invalid error would pop up when trying to send back a token that was already at the back.
  • Fix a Firefox bug with spacing between the battle map search field and the Sort/Filter buttons on the dashboard.

Tarrasque.io v0.34.1

The big rewrite of the backend and the underlying infrastructure is finally finished! Development pace will go back to normal now 🙂  Enjoy!

What's new:

  • The Big Rewrite. For the nerds among you, Tarrasque.io is now running in secure containerized microservices, with the ability to scale as traffic demands, and the security of a Stone Golem! As a result of this and a few other optimizations, things should feel much snappier!
  • Multiple monster and spell imports from the SRD. Gone are the days of importing each creature one-by-one! Prepare your adventures efficiently by importing the creatures you need all at once!


  • A warning message is now shown when the connection to the server is lost, either due to an update or something else going wrong. This should let you know if you're not receiving real-time updates and need to refresh!

Bug fixes:

  • Fixed an issue with the chat toggle showing a negative number of unseen messages when chat history is deleted.

Tarrasque.io v0.34.0: Map Notes & Grid Alignment Tool

Today's update brings a few highly-requested features, some bug fixes, and a couple quality-of-life improvements. Enjoy!

What's new:

  • Grid alignment tool. You can now accelerate your grid setting-up process even further! Zoom in as much as possible on your map, open up Grid Settings, click on the Alignment Tool icon, and draw a rectangle covering a grid square. The drawn grid dimensions will be rounded up, but that should get you close enough for any further modifications.

  • Map notes. Mark a secret door, add points of interest, write flavor text, or remember to spring your traps. You can now switch to the Note tool on the Toolbar and click anywhere on the map to add a note for just about anything in your games. Only for the DM's eyes!

  • Constrain grid proportions. If you know you have a square grid, click the chain icon to make your cell width and height follow each other's values. This should make it a tiny bit faster to set up maps with consistent grids.


  • Skip dead combatants. Tarrasque.io will now automatically skip creatures in the Combat Tracker that are dead! This excludes adventurers who may be rolling death saving throws.
  • Rich text editor toolbar. The editor toolbar is now always visible above any rich-text editable area.
  • Redirect to map for password-protected maps. You can now redirect viewers to any map, regardless of if it's been shared with your players or is password-protected.

Bug fixes:

  • Fixed a bug where multi-selected combatants of the same creature would get added into combat with the same counter.
  • Fixed a bug on the Chat which caused autoscrolling to the last message not to work properly.
  • Fixed a UI bug on the Chat where player avatars were pushing the content down, thus hiding the text box.
  • Fixed an issue with the Previous button being active during the first turn of the first round of combat.

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.
