Jellyfin Interactive Integration Plugin

April 19, 2026 · View on GitHub

A Jellyfin plugin that synchronizes funscript playback with Buttplug-compatible devices via Intiface Central.

Features

Funscript indexing — scans your media library and indexes .funscript files alongside their corresponding video files
Device control — connects to Intiface Central via WebSocket and drives Buttplug-compatible devices in sync with video playback
Script auto-load — automatically loads the best-matching funscript when a video starts and a device is connected
Playback transforms — offset, remap, limit, and half-speed controls for fine-tuning script output
Video OSD integration — funscript heatmap and live debug meter overlaid on the Jellyfin video player
Self-contained — no external plugin dependencies; script injection into the Jellyfin web client is handled by a built-in ASP.NET Core middleware

Download the latest release zip from the Releases page
Extract the contents into a subfolder under your Jellyfin plugins directory (e.g. plugins/interactiveintegration/)
Restart Jellyfin
Open Dashboard → Plugins and verify that Interactive Integration is listed and active

Open Dashboard → Interactive Integration to configure:

Script scan paths — additional directories to scan for funscripts beyond the media library
Intiface WebSocket URL — the address of your Intiface Central server (default: ws://localhost:12345)

After changing the scan paths, run Scan Interactive Script Index from the scheduled tasks page to rebuild the index.
