JellyFlare — announcement banners for Jellyfin [Plugin]

JellyFlare — announcement banners for Jellyfin

I manage a Jellyfin server for about 30 users and kept running into the same problem: no way to tell them anything. Maintenance windows, library changes, holiday notices — nothing. The only options I found were raw CSS hacks or hand-written JS Injector scripts that break the moment you want to change a message.

So I built JellyFlare — a plugin that adds a configurable announcement banner at the top of the Jellyfin UI.

What it does:
- Rotating messages with per-message colour, optional link, and scheduling (fixed date range, annual, weekly, or daily time window)
- Permanent banner mode for urgent notices — overrides rotation in one click
- Full admin UI: add, edit, reorder messages from the dashboard, no file editing, no restarts
- Dismiss controls (× per message, hide-all button) configurable by the admin
- Hides itself on admin pages so it doesn't get in your way

Honest caveats: requires JS Injector and File Transformation as prerequisites, and is currently locked to Jellyfin 10.11.6+.

Happy to hear feedback — especially on scheduling modes or anything you'd want that's missing.

That looks cool. I'm not able to try it as I'm not migrating past 10.10.7 quite yet but from the short clip on the GIT I'm wondering if you can have an option for the banner to always be on, or have the space reqerved, The bump down, move up, bumpb down would annoy me ay a user level. Maybe down the road be able to add in other notices built around the library like listing new content namees/episodes, current time and weather widgets, maybe even sports trackers. Just tossing quick ideas out. Amazes me how so many can think these things up and then have the skills to bring them to life!

Hi! Thanks for your feedback!
Yes there is an option for permanent banners or a set of rolling ones. The demo has a quick refresh on purpose, but everything is configurable and default to a minute of display then 2 of cooldown, which does the job without annoying users on a daily usage.

Good ideas! For now, the goal is about manually typed announcements, but variables like ${RECENTLY_ADDED_MOVIE} would be nice. I prefer the home sections for this use and currently uses the banners for special spotlights of individual movies or shows. Worth thinking about it!

Yes, for now the plugin features are only supported on the web-based clients (desktop, ios, android,...). To have maximum compatibility would mean to use Jellyfin message API but is currently limited and not handled by every client still.

But thanks for the heads up!

I've noticed users aren't, well, smart enough, to look at the recently added section all that often. Plus just having something in the banner for a quick read is easy to check. Especially if this banner continues across various pages and isn't locked oto just the main page. Just my observation. It's hte 10,000 channels and nothing's on syndrome.

Adding more features is just a cool idea. For sure get this working well the way you want before stretching yourself to far.

That is a fair point, a quick glance at a banner is much lower friction than scrolling through a section. The banner does follow users across pages by the way, it is not locked to the home screen.

Yeah just my thoughts. I use the Spotlight plugin which cycles movie info, fanart and trailers on the main page which shows random movies and TV shows and it's spurned me to remember lots of things that get burried deep into my library and I get more ideas to watch things. Basically it's advertizing that works!
