Read full descriptionHide full description
Borealis Builder is a free, open-source character builder for fifth edition tabletop roleplaying games. Build a hero step by step, level up from 1 to 20, track your sessions and print a clean character sheet. No account, no ads, no tracking: your characters stay on your device. BUILD STEP BY STEP • Choose a species or race, class, background, ability scores, languages, proficiencies, feats and equipment, in the order you would at the table. • Roll your ability scores, use point buy or take the standard array. • Level up from 1 to 20, with subclasses and multiclassing. TWO RULE SETS IN ONE APP • The 2014 rules (SRD 5.1) and the 2024 rules (SRD 5.2.1) are both included. • Pick the rules for each character; a character keeps its rules all the way to level 20. SPELLS • Choose cantrips and spells for every caster, keep a wizard's spellbook, prepare the day's list and read every spell in full. • Spell slots follow your levels, including multiclass casters and Pact Magic. AT THE TABLE • Track hit points, spell slots, concentration, resources, conditions and your own trackers on the Play tab. • Short Rest and Long Rest are one tap away. • Tap a number to see where it comes from. CHARACTER SHEETS • Create a PDF character sheet with stats, skills, attacks, features, spell pages and cards. • Colour or ink-saving, fillable or flattened, Letter or A4. YOUR OWN CONTENT • Import content you own or are licensed to use: Aurora files (.xml and .index), .dnd5e character files, 5etools-format JSON, .zip archives and index links. • See a preview before anything is installed. Files are converted on your device by plain parsing, with no AI involved. • Homebrew sits in the compendium next to the included rules and can target either rule set. YOUR DEVICES, NO CLOUD • Send characters and content to your other devices over your own Wi-Fi by scanning a QR code. No cloud and no relay server. • Characters are files you can copy, back up and share. PRIVATE BY DESIGN • No account, no sign-up, no ads, no analytics. • Borealis goes online only when you ask it to, for example to update an index link you added.

Verdict
The clearest difference is in-app purchases: Borealis Builder at none against Hidden's 3. Borealis Builder also leads on ads (none vs shown) and update cadence (every 3 days vs every 6 weeks). On price, device support and iOS requirement there is nothing between them.
