Threadfall Party Sync

About

Threadfall Party Sync is the official one-click party sync for Game Masters running campaigns on D&D Beyond and tracking them in Threadfall.

WHO IT'S FOR
Game Masters who want the party roster from their D&D Beyond campaign mirrored into a Threadfall campaign they already own — without copy-pasting JSON or asking each player to send their character. Designed for "import once when you start the campaign, refresh after every level-up."

HOW IT WORKS (two clicks)
1. Open a D&D Beyond campaign you GM. The extension's toolbar icon shows a teal dot, so you know it's relevant for this page.
2. Click the toolbar icon. The popup detects the D&D Beyond campaign, auto-matches it against the Threadfall campaigns you GM, and shows you the party with every character pre-checked. Hit "Export to Threadfall."
That's it. Each character refreshes in place if you've imported it before, or lands as a new PC in your Threadfall campaign if it's new. Class, level, stats, inventory, spells, features, backstory — everything D&D Beyond knows.

SMART AUTO-MATCH
The extension fuzzy-matches your D&D Beyond campaign name against the Threadfall campaigns you GM. It auto-selects at 75% confidence (so "Sisters of Phandalin" matches "Sisters of Phandelin" without effort). If it picks wrong, you can override with a dropdown. If you're targeting an unfamiliar campaign, a confirmation prompt asks "sure this is the right one?" before any data lands.

NO ONBOARDING FRICTION
You're already signed into Threadfall. The extension reads your existing session — no API keys, no DevTools, no copy-paste. Sign in once, you're done.
DESIGNED AROUND D&D BEYOND'S PERMISSION MODEL
The extension never bypasses D&D Beyond's access control. It uses the same authentication flow D&D Beyond's own character-sheet app uses. If a player hasn't shared their character with the campaign in D&D Beyond, the extension skips it silently and reports back which players need to enable sharing — no scraping fallbacks.

PRIVACY
• No analytics. No tracking. No third-party SDKs.
• Only network calls: D&D Beyond's own APIs (using your session) and your Threadfall server.
• Your token and import history are stored in chrome.storage.sync — synced across your Chrome instances but never sent to any third party.
• Full privacy policy linked in the listing.

REQUIREMENTS
• A Threadfall account at https://thread-fall.com.
• Game Master role on at least one Threadfall campaign.
• A D&D Beyond account with at least one campaign you manage.
• Player characters set to "share with campaign" in D&D Beyond if you want them imported.

NOT AFFILIATED WITH WIZARDS OF THE COAST OR D&D BEYOND
This extension is an independent tool. D&D Beyond is a trademark of Wizards of the Coast LLC. The extension only reads campaign rosters and character data D&D Beyond already shows to the signed-in user through D&D Beyond's own authenticated API.
