10/8/2026
Highlights
- A new, cleaner look that works on phones and tablets, with 10 themes and a Large text option.
- Campaign Rolls: a dice button on every page and a shared rolls panel for your campaign. Rolls are made on the server, so nobody can fake them.
- A rebuilt GM Board, a new home page, and a Characters page with portraits.
- All six calculators now run instantly in your browser.
- Import characters straight from GURPS Character Sheet (GCS 5) files.
- Counters on the character sheet for ammo, durations, Luck and more.
New look
- Every page has been redesigned: calm cards, clear titles with the Basic Set page reference, and a quiet Help link.
- Works properly on phones and tablets: bigger tap targets, no sideways scrolling, a Menu button on small screens.
- 10 themes based on well-known editor palettes: GitHub Light, Rosé Pine Dawn, One Dark, Dracula, Tokyo Night, Noctis, Green phosphor, SynthWave '84, Amber CRT and High contrast, plus Match my device. Your old theme choice moves to the closest new one.
- A separate Large text setting that works with every theme.
- A new "3d" logo and site icon.
- Smoother page changes in modern browsers, and pages load faster when you hover a link.
- The site's own confirm dialogs replace the browser's pop-ups, and follow your theme.
Home page
- A real home page: jump back into your recent characters, see your campaigns and their latest rolls, open any tool, and catch up on what's new.
Campaign Rolls
- A floating dice button on every page rolls 3d.
- A Campaign Rolls panel shows every roll in your campaign: sheet rolls, attacks, defenses, spells, calculator rolls and GM Quick Checks. Docked on the right on a computer (and resizable), a bottom sheet on phones.
- Rolls posted to the campaign are made on the server, so nobody can fake them.
- GMs can roll in private: a Public/Private button for their panel rolls and their Quick Checks.
- "Playing as" in the top bar: pick which character (or GM) you are rolling as, across all your campaigns. Opening your character switches it automatically.
- Calculators: Roll on your own screen, or Roll to campaign to share the result.
GM Board
- Rebuilt around a Party table: click a character (or press 1-9) to see their skills and armor; sort by name, HP, FP or Speed (turn order).
- Quick Check rolls an attribute, sense or Fright Check for the whole party in one click, as one message in Campaign Rolls.
- Search the whole party's skills at once.
- Characters joining or leaving the campaign show up without reloading.
- Pick and manage your campaigns from the GM Board.
Characters
- Import your characters straight from GURPS Character Sheet .gcs files (GCS 5).
- The Characters page shows portrait tiles, or a sortable table, split into Player characters and NPCs & monsters.
- Share any character with a link: anyone with the link can view it.
- Counters on the character sheet: ammo, durations, days, Energy Reserve, Luck or anything else, one tap to change, with suggestions from the character's weapons and traits.
- Character sheet tidied: notes show once, long text wraps, page references and points line up.
- The combat rules follow the Basic Set more closely: critical hits and misses, damage caps, minimum injury, fractional armor divisors, posture for unarmed attacks, and hit locations rolled on 3d.
Calculators
- All six calculators run in your browser and update as you type: no waiting on the server.
- A Reset button on every calculator, and results appear once you start.
- Work/Study: hours already spent count as real hours.
- Hiking: skates cancel the ice weather penalty, and an empty party no longer causes an error.
- Collision and Fall: only the fields for the type you pick are shown.
Settings and account
- One Settings page: account, display and rules together, saved as you change them.
- Remember me keeps you signed in for 30 days.
- Stronger password storage, upgraded automatically the next time you sign in.
- Report a bug or request a feature from inside the site.
- A new About page.
Support the site
- A support meter on the home page and About: this month's running costs and how much is covered, then the features supporters help bring sooner. Anything beyond running costs goes toward the next feature on the roadmap.
- Support on Patreon moved from the top bar to the Settings menu.
Bugs and security
- Many fixes across calculators, the GM Board, characters and campaigns.
- Protection against cross-site request forgery and unsafe text in character data.
- Saves that failed now say so instead of looking successful.
Features removed
- The Tracker page: character Counters replace it, and attacks are rolled from the character sheet.
- The Monster Repository: share characters by link instead.
- Character tags and the Combat Effectiveness Rating (CER): characters are now Player characters or NPCs & monsters.
- The Music page.
- The automatic "Default Campaign": GMs create campaigns and share them with their players.
- Importing from GURPS Character Assistant (GCA) and GCS 4: open the character in the current GCS and save it again.
Fixes since launch
- Shotguns and other multiple-projectile weapons (RoF 2x9): the weapon shows its RoF as written, you choose Trigger Pulls, and the pellets count for Rapid Fire and hits (B409). Before, RoF 2x9 came in as 0.
- Extremely close range: within 10% of 1/2D, each trigger pull is one hit with damage dice and the target's DR multiplied, as the Basic Set describes (B409). The Distance box decides it, so a shotgun rolled at the default 1 yard is extremely close.
- A Recoil box in the Attack dialog. Split recoil like 1/7 (shot/slug) starts at the first number; enter the second for slugs.
- Rapid-fire attacks score every extra hit the margin earns; before, extra hits stopped once the roll plus recoil reached 17.
- Rolling an attack no longer blanks the weapon's range, shots, bulk, accuracy, block and parry. Characters uploaded before these fixes are repaired when they load, with no re-upload needed.
- Selected rows and the HP/FP status warnings are highlighted again in every theme, and pages no longer scroll on their own.
- Deploys no longer sign everyone out.
