What Happened to Plex Meta Manager?

On April 25th 2024, the Plex Meta Manager name was officially retired and replaced with Kometa. This change was essential to avoid a trademark issue with Plex.

Kometa (formerly known as Plex Meta Manager) is a powerful tool designed to give you complete control over your media libraries. With Kometa, you can take your customization to the next level, with granular control over metadata, collections, overlays, and much more.

Kometa Defaults

Want your library to look like the above images? With the Kometa Defaults you can! These powerful and modular files were designed by the Kometa team to make it simple to create a personalized, one-of-a-kind media collection without the hassle of manually defining each one.

Want to see what the community has to offer? Check out the Kometa Community Configs repository on GitHub to see user-submitted configuration files, or even add your own to the mix!

With Kometa, you can also manage metadata for all your media types, from movies and shows to music and more. And since your metadata is managed outside your libraries, you'll never have to worry about losing your customizations in the event of a media server database loss, you can simply reapply them! It is also easy to move your customizations between servers if you need to.

Getting Started

To get started with Kometa, follow these simple steps:

  1. Install Kometa on your device. You can find the installation instructions for a variety of platforms here.

  2. Once you have installed Kometa, create your Configuration File. This file contains important information such as URLs and credentials needed to connect to services like Plex and TMDb

  3. After creating the Configuration File, you can start updating Metadata and building automatic Collections by creating a Collection File for each Library you want to work with. If you'd rather use some of our pre-made Collection Files, take a look at the Kometa Defaults

  4. Finally, check out the Wiki, you'll find new and exciting ways to truly unlock the potential of your libraries.

Step-by-Step Guides

If you're a beginner to the concepts of Python, Git and/or Kometa and find the above steps challenging, don't worry. We've got some step-by-step guides that can help you get started. These guides will take you through the process of installing Kometa, creating your Configuration File and getting some basic Collections up and running.

For those who need full installation walkthroughs, please refer to the following walkthrough guides:

If you are using unRAID, Kubernetes, QNAP, or Synology refer to the following basic guide to Docker container setup for each system:

this doesn't cover the Kometa setup specifics found in the guides above with regard to creating the config file and collection file, so you may want to go through the Docker Walkthrough first on your computer to gain that understanding.

Example Usage

Kometa puts you in control of your media library by letting you create custom Collections that make discovering and organizing your content a breeze. With powerful search and filtering options, you can build Collections based on popular builders like TMDb, IMDb, Trakt, and many more.

Imagine having Collections like these at your fingertips:

  • Trending and Popular (based on TMDb, IMDb, Trakt, etc.)
  • Streaming Services (like Netflix, Disney+, and more)
  • Networks
  • Studios
  • Genres
  • Actors
  • Decades

Kometa gives you endless possibilities to curate and organize your media library any way you want. Create custom Collections and Overlays that fit your unique preferences and make discovering your content effortless.

But if you don't want to spend time manually creating Collections and Overlays, we've got you covered. Check out the Kometa Defaults - a handcrafted selection of tried-and-tested Collections and Overlays made by the Kometa team.

Alternate Branches

The Develop and Nightly branches are "beta" versions of Kometa that are updated more frequently than the stable version (Master branch). These branches are where bug fixes, new features, and other changes are added before being released to the Master branch.

However, these branches (especially Nightly) are recommended for more technical users who don't mind updating frequently to get the latest changes. Keep in mind that these beta branches may have bugs or other issues that could cause problems with Kometa or your media server. So, if you're not comfortable with technical issues, it's best to stick with the Master branch.

Develop Branch (click to expand)

Develop GitHub commits since latest stable release (by SemVer)

The develop branch has the most updated documented fixes and enhancements to Kometa. This version is tested and documented to some degree, but it is still an active Develop branch, so there may be rough edges.

Switching to develop:

Add ":develop" to the image name in your run command or configuration:


In the directory where you cloned Kometa:

git checkout develop
To switch back:
git checkout master

If switching to the develop branch, it is recommended to also use the develop branch of the wiki, which documents any changes made from the Master branch.

Nightly Branch (click to expand)

Nightly GitHub commits since latest stable release (by SemVer)

This branch will have squashed commits which can cause git pull/git fetch to error you can use git reset origin/nightly --hard to fix the branch.

The nightly branch has the absolute latest version of Kometa, but it could easily break, there is no guarantee that it even works, and any new features will not be documented until they have progressed enough to reach the develop branch.

Switching to nightly:

Add ":nightly" to the image name in your run command or configuration:


In the directory where you cloned Kometa:

git checkout nightly
To switch back:
git checkout master

As this branch is subject to extreme change, there is no promise of the feature being documented in the nightly branch of the wiki and all discussions relating to changes made in the nightly branch will be held within the Kometa Discord Server.

lmxl Variants for Unsupported Hardware

In March 2024, lxml, a prerequisite for operating Kometa, ceased support for older CPUs. This impedes users from running Kometa on unsupported hardware.

To address this issue, we have implemented 'lxml' variants for each Kometa branch (master, develop, and nightly). These variants resume compatibility with older hardware by freezing lxml on a previous version which has wider hardware support.

To transition to the lxml branch, simply prepend 'lxml-' to the branch name you are currently utilizing. For instance, Kometa-Team/Kometa:lxml-master, Kometa-Team/Kometa:lxml-develop and Kometa-Team/Kometa:lxml-nightly.
