Sanctum

Sanctum is an all-in-one campaign manager for D&D 5e Dungeon Masters. Every part of your game (characters, NPCs, combat, maps, quests, lore) lives in a single fast, offline app that runs entirely on your own machine. No account, no cloud, no subscription. Your campaign is a file on your computer, and it stays yours.

🎲 Everything for the table

• Characters & NPCs. Track PCs, currency, hit dice, magic items, and a full bestiary of stat blocks.

• Combat tracker. Initiative, concentration tracking with DC prompts, and a live combat log, plus an encounter builder.

• World & maps. Organize locations and drop in your own battle/region maps.

• Quests, factions & rumors. Keep your plot threads, power players, and table talk straight.

• NPC relationship graph. See who loves, hates, and owes whom at a glance.

• Handouts. Prep player-facing images and reveal them when the moment's right.

• Shops, calendar & story timeline. Inventories, in-world dates, and your campaign's history.

• Session notes. Markdown notes and session prep, all in one place.

🖥️ Player Screen

A separate player-facing view for a second monitor or TV. Show your table only what they should see.

⚡ Built for speed at the table

• Global search + command palette (Ctrl+K) to jump anywhere instantly.

• Built-in D&D 5e rules quick-reference.

• One-click campaign export/import and automatic daily backups. Your data is portable and safe.

🔒 Local-first & open source

Sanctum keeps 100% of your data on your device (%APPDATA%\Sanctum). It works fully offline and is free and open source under AGPL-3.0.

 This is an early release. I'd love your feedback!

I'm sharing Sanctum to hear what real DMs think. What's useful? What's missing? What felt clunky? Drop a comment. Every bit helps shape where it goes next.

 Note: Sanctum isn't code-signed yet, so Windows may show a blue "Windows protected your PC" screen on first launch. Click More info → Run anyway. It's safe. The full source is linked above.
