Manually transferring creatures, spells, items, and dice rolls from 5etools into Foundry VTT is tedious and error-prone. Rivet automates this by relaying data from the 5etools webpage directly to the Foundry VTT instance running in another browser tab.

User browses 5etools in one tab → clicks a send button next to an entity or rolls dice → Rivet content script captures the event → service worker finds the Foundry VTT tab (localhost:8080/game) → relays data to Foundry VTT's Plutonium module for import

Target users: D&D 5e players and DMs who use both 5etools and Foundry VTT / Game masters running Foundry VTT sessions who reference 5etools content

Cannot verify Foundry VTT side (Plutonium module) behavior as it runs outside the extension
Extension is very small (~42KB) with minimal code; straightforward message-passing architecture

Monetization

No paid features detected

No payment integration, no premium feature gating, no upgrade UI, no billing/subscription/checkout code. All keyword hits for 'pro' are false positives from JavaScript Promise constructors. The 'license' hit is the MIT open-source license file. The extension provides all features freely with no tiered access.

Confidence: 98
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension operates entirely locally as a message bridge between the 5etools website DOM and Foundry VTT browser tabs. It uses no authentication, no login UI, no account creation, and no external service requiring credentials. The only external host is localhost:8080 (standard Foundry VTT local server). The 'jwt' keyword hit is from base64-encoded content hashes in the Chrome Web Store metadata file, not authentication. The 'auth' hit is from the MIT license warranty disclaimer.
