Plex vs. Jellyfin on UGREEN NAS: Which Should You Use?

Choose Plex when your household needs broad client support, simpler account-based sharing, and easier remote viewing—and you accept its paid remote-streaming and hardware-transcoding features.

Choose Jellyfin when you want free hardware acceleration, local user accounts, and greater control over the server—and you are comfortable configuring clients and secure remote access yourself.

Can Your UGREEN NAS Run Plex or Jellyfin?

Check the NAS model before comparing software features. Plex and Jellyfin both depend on container support on UGREEN NAS, including the Jellyfin application available through the UGREEN App Center.

If your current NAS cannot run the server you need, you can browse and filter UGREEN NAS models before deciding whether to run the server on another device or change hardware.

Where does UGREEN Theater fit? UGREEN Theater is the native UGOS Pro media-library and playback application. It can be the simpler option when you want to organize and watch media through the UGREEN ecosystem. Plex and Jellyfin become more relevant when you need their broader client ecosystems, separate user accounts, remote streaming, plugins, or advanced server controls.

Once the hardware is eligible, the choice becomes less about the NAS enclosure and more about how the people in your household will use the library.

Plex vs. Jellyfin at a Glance

Both platforms organize a personal media library and stream it to supported devices. The practical difference appears when a television cannot Direct Play a file, a family member connects from outside the home, or the server owner wants complete control over accounts and networking.

Start with the Devices That Will Play Your Media

The client device determines whether a video can play directly or must be converted by the NAS.

Direct Play occurs when the client supports the file’s container, video codec, audio codec, and subtitles. The NAS sends the original stream with little processing. This produces the best quality and places the smallest load on the server.

Transcoding begins when part of the file is incompatible with the client:

• A video codec the television or streaming device cannot decode
• Unsupported audio such as certain lossless or multichannel formats
• A container the client does not accept
• Image-based subtitles that must be burned into the video
• A remote-streaming limit lower than the original video bitrate

Before choosing a server, list the devices that will actually play the media: smart TVs, Apple TV, Roku, Fire TV, Android TV, phones, tablets, browsers, or game consoles.

Plex is generally the easier starting point for a household with many device types and users who do not want to enter server addresses or manage connections manually. Its centralized account system also makes sharing a library with relatives more familiar.

Jellyfin offers clients for many platforms, but client availability and feature maturity can differ by device. Check the exact application available for your primary television or streaming box. The Jellyfin client documentation also explains how codec and subtitle support affects Direct Play.

Choosing media formats that match your clients reduces the need for either server to transcode. H.264 video and SRT subtitles remain broadly compatible choices for older playback devices, while high-bitrate HEVC, lossless audio, and image-based subtitles are more likely to expose differences between clients.

Local playback can make Plex and Jellyfin feel similar. Remote streaming makes their cost and setup models much easier to distinguish.

Remote Streaming Changes the Cost and Setup

Plex Media Server is free to run for local playback. Under Plex’s current rules, remote personal-video playback requires one of the following:

1. The server owner has an active Plex Pass.
2. The viewer has an active Plex Pass.
3. The viewer has a Remote Watch Pass.

When the server owner has Plex Pass, other users with access to that server can stream its personal video library remotely without buying a separate Remote Watch Pass.

Plex simplifies account-based discovery, but it cannot eliminate every network limitation. CGNAT, double NAT, router settings, and insufficient upload bandwidth can still prevent a direct connection or reduce streaming quality.

Jellyfin does not charge for remote streaming. Because it is fully self-hosted, you must create the secure route into your home network. A VPN is a good starting point for personal access. A properly configured HTTPS reverse proxy is more suitable when several users need conventional app access.

Jellyfin advises against forwarding its service port directly to the public internet. Its networking documentation recommends protected access methods and HTTPS for internet-facing deployments. Our guide to securing a UGREEN NAS and home network covers the account, firewall, and remote-access controls that should surround any self-hosted service.

Upload speed affects both platforms. A home connection with 40Mbps of upload bandwidth cannot reliably deliver a 60Mbps video remux without reducing the stream bitrate. Plex or Jellyfin can transcode the file to a lower bitrate, but that moves the workload back to the NAS.

Hardware Transcoding Changes the Server Requirements

Hardware transcoding uses a processor’s video engine to convert compatible media with less CPU load than software transcoding. It becomes important when clients cannot Direct Play, remote bandwidth is limited, or several users request incompatible formats simultaneously.

On UGREEN NAS, Plex hardware transcoding requires all three of these conditions:

1. A compatible Intel Quick Sync processor
2. Graphics access enabled for the Plex container
3. An active Plex Pass

This makes Intel DXP models the clearest choice for a UGREEN Plex server expected to transcode video. The DH4300 Plus and AMD-based GT models can run Plex, but they do not provide the same recommended Intel Quick Sync path. Direct Play should therefore carry more weight when evaluating those models for Plex.

Jellyfin does not charge for hardware acceleration. It supports several acceleration methods, including Intel Quick Sync, AMD VA-API under Linux, and Rockchip RKMPP. The correct method depends on the NAS processor, container, device access, drivers, codecs, and optional stages such as HDR tone mapping. Jellyfin’s hardware-acceleration documentation explains those different paths.

Hardware acceleration does not make every transcode effortless. Subtitle burn-in, unsupported profiles, HDR tone mapping, and audio conversion can leave part of the job on the CPU. Two files with the same resolution can therefore place very different loads on the NAS.

For most households, the best sequence is:

1. Select clients that Direct Play the library’s common formats.
2. Use hardware transcoding for exceptions.
3. Test the actual high-bitrate, HDR, audio, and subtitle combinations used at home.

After performance, the remaining difference is who controls the accounts, metadata connections, and remote-access path.

Privacy Depends on Accounts, Metadata, and Remote Access

Plex uses Plex accounts to claim a server, manage access, and connect clients. Its services process account and server-related information under the Plex Privacy Policy. Optional integrations and playback-data settings can increase the information exchanged with Plex services.

Jellyfin accounts are created and stored on the server. The server can run without an internet connection, and access does not depend on a centralized Jellyfin account service.

That does not mean a Jellyfin server sends no external requests. Metadata providers need internet access to retrieve posters, descriptions, ratings, and other library information. Plugins may contact their own services, and remote users still exchange traffic with the server through the access method you configure.

The practical privacy distinction is control:

• Plex provides a managed account and remote-access ecosystem.
• Jellyfin gives the administrator more control over accounts, networking, plugins, and metadata sources.
• Both still require strong passwords, updates, protected remote connections, and restricted permissions.

For a household that values convenience, Plex’s external account layer may be an acceptable tradeoff. For someone building a self-hosted environment specifically to control accounts and network paths, Jellyfin is the more natural fit.

Which One Fits Your Household?

Plex is the stronger default when the people watching the library should not need to understand how the server works. Jellyfin is the stronger default when the person operating the server wants control and is comfortable maintaining the access path.

The choice is also reversible. You do not need to migrate or duplicate the entire media library just to find out which experience works better.

Try Both Before You Migrate

Plex and Jellyfin can use the same media folders. Give each server its own configuration directory, database, port, and container. Mount the shared media folders as read-only where possible so neither application can modify the original files.

You can then test both servers with the household’s actual devices and media:

• Open the same 4K video on the primary television.
• Test the subtitles your family uses.
• Try local playback and a controlled remote connection.
• Check whether the server Direct Plays or transcodes.
• Ask a nontechnical family member to sign in and find a movie.
• Compare how each client handles posters, collections, watch progress, and user profiles.

Monitor memory while both servers run, especially on a NAS with 8GB of fixed memory. Library scanning, thumbnail generation, and metadata processing can temporarily increase CPU and memory use.

Plex and Jellyfin keep separate databases. Watch history, users, posters, collections, and server settings do not transfer automatically between them. Back up each server’s configuration before removing a container or committing to a migration.

When you have made the decision, follow the dedicated setup guide:

• Install Plex on UGREEN NAS
• Install Jellyfin on UGREEN NAS

Frequently Asked Questions

Is Jellyfin completely free?

Yes. Jellyfin is free and open-source, including its server software, remote-streaming functions, and hardware-acceleration features. You may still incur costs for the NAS, drives, electricity, network equipment, domain name, VPN, or other infrastructure used to operate it.

Does Plex require Plex Pass?

Plex does not require Plex Pass for running a server and streaming personal media on the local network. Plex Pass is required for Plex hardware-accelerated streaming. Remote personal-video playback also requires Plex Pass or Remote Watch Pass under Plex’s current access rules.

Can the UGREEN DH2300 run Plex or Jellyfin?

No. The DH2300 does not support Docker, so it cannot host Plex Media Server or the containerized Jellyfin application from the UGREEN App Center. It can store media for a Plex or Jellyfin server running on another computer or compatible NAS.

Can Plex and Jellyfin use the same media folders?

Yes. Both servers can scan the same movie, television, music, and photo folders. Give each application a separate configuration directory and mount the shared media folders as read-only when possible. Their users, watch history, metadata databases, and server settings remain separate.
