Nettle 0.3.0 (formerly Slopfin) — beta

A fast, beautiful Jellyfin client for Windows and Linux, built on mpv. Direct play only: Nettle never asks your server to transcode.

Note

Slopfin is now Nettle. Same app, new name and a new sea nettle logo.

  • Already on Slopfin 0.1 or 0.2? Use Settings → Updates → Check now. Your settings, saved sign-ins and theme come along automatically, and your Start-menu / desktop shortcuts are renamed to Nettle.
  • The logo takes the colours of whichever theme you pick, including the window and taskbar icon.

Warning

The Linux build is untested for a short while. The Linux test bench is being reconfigured, so this release was only tested by hand on Windows. The Linux AppImage still passes the automated decode tests on clean Ubuntu, Debian, Fedora and Arch machines, and hands-on Linux testing will follow soon. If you're on Linux, a test report would really help.

Note

Entirely AI-coded, single-user tested. All of Nettle's code was written by an AI coding assistant (Anthropic's Claude), directed and reviewed by one person, and so far tested only by that person.

About the name change

Nettle was called Slopfin for its first two releases. It was renamed in 0.3.0, partly because an unrelated project with a very similar name (a Jellyfin client for PS5 consoles) kept causing confusion.

Why "Nettle": it's named after the sea nettle (Chrysaora), a jellyfish, as a nod to Jellyfin. The new logo is a sea nettle silhouette that takes your theme's colours.

What happens when you update from Slopfin:

  • Nothing to reinstall. Settings → Updates → Check now installs Nettle over Slopfin.
  • Settings, saved sign-ins and theme come along. On first start, the data folder moves from Slopfin to Nettle. If the old folder is in use, it's copied instead and the original is left alone.
  • Shortcuts:
    • Windows: Start-menu and desktop shortcuts are renamed to Nettle, and the app shows as Nettle in Windows' Apps list. Taskbar pins keep working.
    • Linux: your applications-menu entry is updated in place, so a dock pin stays pinned.
  • Your Jellyfin server shows the app as "Nettle (Windows)" or "Nettle (Linux)", and you stay signed in.

What still says "Slopfin" (on purpose): the update packages below (SlopfinApp-…nupkg) and the Windows install folder (%LOCALAPPDATA%\SlopfinApp). The updater finds existing installs by that internal ID, so keeping it is what lets everyone update without reinstalling.

The repository moved too: it's now devall96/Nettle. Old devall96/Slopfin links, and the update address saved in Slopfin's settings, redirect here automatically.

What's new in 0.3.0

  • New name: Nettle. Named after the sea nettle, a jellyfish (a nod to Jellyfin).
  • New logo, a sea nettle silhouette that follows your theme's colours everywhere: the sidebar, and the window and taskbar icon.
  • Data saved under the old name moves over by itself on first start, so nobody is signed out:
    • On Windows: %LOCALAPPDATA%\Slopfin → %LOCALAPPDATA%\Nettle.
    • On Linux: ~/.local/share/Slopfin → ~/.local/share/Nettle, and the applications-menu entry is updated in place.

Everything from 0.2.0 is unchanged: still-watching prompt, scrubbing previews, audio passthrough, Seerr season picker, 16 themes and the rest.

Install on Windows

  1. Download Nettle-win-Setup.exe below and run it. It installs for your user only, with no admin rights needed.
  2. Windows may show "Windows protected your PC" because Nettle isn't code-signed yet. Click More info → Run anyway.

Prefer not to install? Use Nettle-win-Portable.zip.

Install on Linux

  1. Download Nettle.AppImage below and make it executable (right-click → Properties → Allow executing as program, or chmod +x Nettle.AppImage).
  2. Double-click it. Nettle offers to add itself to your applications menu.

Already using the Slopfin AppImage? Settings → Updates updates it in place.

Which file do I download?

You're on Download
Windows Nettle-win-Setup.exe (or Nettle-win-Portable.zip to run without installing)
Linux Nettle.AppImage

Ignore the other files. The .nupkg and .json files and RELEASES are read by the built-in updater. They still carry the old internal name (SlopfinApp), so existing installs keep finding their updates. "Source code" is added by GitHub to every release.

Both builds include mpv and the libraries it uses (FFmpeg, libplacebo and others), unmodified. Their licenses and source locations are listed in THIRD_PARTY_NOTICES.md.
