JDownloader 2 — KasmVNC and Dark Mode edition for Unraid

The complete download manager in your browser — monochrome Carbon dark, nothing to set up.

   

What is this?

JDownloader 2, the full-featured download manager, running as one Unraid container and streamed to your browser via KasmVNC — no native install, no SSH. The entire GUI (download list, link grabber and the Advanced Settings table) is rendered in a clean monochrome IBM Carbon (#161616) dark theme, with light, readable progress bars and a green speed graph. It auto-installs and themes itself on first start and is configured entirely from the Unraid template.

Highlights

• Complete dark UI — monochrome IBM Carbon #161616 across the whole interface, not just the menu bar; one variable flips it to a matching light theme

• KasmVNC web desktop — hardware-accelerated rendering, real browser clipboard, native file upload/download, high-DPI

• Turnkey — auto-installs JDownloader, auto-confirms its first-run prompts, and the theme self-heals after JD's own updates

• Update-safe — all config, links and session state live in /config; even hidden columns and column layout survive a restart

• My.JDownloader-ready — pair it once and manage downloads remotely

• Optional WebUI login (CUSTOM_USER / PASSWORD), or leave it open on your LAN

• One container, multi-arch (amd64 + arm64), built on LinuxServer's baseimage-kasmvnc

• Image: ghcr.io/junkerderprovinz/jdownloader:latest

Requirements

• Unraid 6.10+

• Open the WebUI over HTTPS (port 3001) for the seamless browser clipboard — accept the self-signed cert once

• First start: JDownloader installs itself, so the WebUI stays black for a few minutes — wait for the JDOWNLOADER IS READY banner in the container log before opening it, and don't restart during the install

Posting a bug report

Please post:

• Unraid version (Settings → System Information)

• Image tag (latest or a pinned vX.Y.Z)

• Output of docker logs --tail 200 JDownloader

• Browser + OS you're using

• Whether you changed JD_THEME, the WebUI ports, CUSTOM_USER/PASSWORD, or the /config / /downloads mounts

GitHub issues with the same info are also welcome: github.com/junkerderprovinz/jdownloader/issues

Built on LinuxServer's baseimage-kasmvnc and KasmVNC. JDownloader 2 is by AppWork. The dark theme is our own IBM Carbon palette, applied through JDownloader's native colour config plus a patched FlatLaf — see the repo for details. If this saved you a setup evening, you can buy me a coffee.

Thanks! Yes, this is the full JDownloader 2, just running its native GUI in your browser via KasmVNC, so all of JD's normal captcha handling works exactly like on the desktop:

• When a filehost shows a captcha, JDownloader pops its captcha dialog right in the web GUI — you solve it there (click/type), same as desktop JD.

• All of JD's built-in options are available under Settings → Captcha: JAntiCaptcha (built-in OCR for simple image captchas), the interactive browser solver for reCAPTCHA/hCaptcha, and external solver services (9kw.eu, etc.).

• You can also link the container to MyJDownloader to get captchas forwarded to your phone/browser.

Nothing is stripped or changed in the container, it's stock JDownloader 2, so its captcha features behave identically.
