Show HN: A faithful recreation of the Plex UI for Jellyfin

A developer released jellex, a single-page Plex Web-style client for Jellyfin that was written entirely by an LLM (Claude) in directed sessions, according to the project's Show HN post. jellex talks to the Jellyfin API directly from the browser with no backend, deploys to Cloudflare Workers via `npx wrangler deploy`, and can be run locally with `npm install` and `npm run dev` at http://localhost:32400. The project includes an AGENTS.md file for further documentation.

A Plex Web-style client for Jellyfin.

Note

jellex was written entirely by an LLM (Claude) in directed sessions.

jellex is a single-page app that talks to the Jellyfin API directly from the browser: there is no backend to run. It deploys to Cloudflare Workers; point it at your server and sign in.

npm install
npm run dev

Then open http://localhost:32400 and sign in to your Jellyfin, or use "Try the Jellyfin demo" to sign in to Jellyfin's public demo server. npm run build builds it, and npx wrangler deploy deploys it (wrangler.jsonc). See AGENTS.md for more.
