Jellyfin vs Plex: Which Media Server Needs the Bigger Server?

Jellyfin vs Plex comes down to who controls your server: Jellyfin is free software with no paid tier, while Plex is a free app that charges for remote streaming and hardware transcoding. As a result, on a rented server, where every viewer is a remote viewer, that difference decides the bill. Meanwhile, the hardware each one needs is almost the same.

This guide compares cost, remote access, transcoding and the server each one asks for. It uses the Jellyfin documentation, Plex’s published CPU guidance, CPU benchmarks and our own arithmetic, and it ends with how many streams each Swify plan can handle.

Jellyfin vs Plex: What Is the Difference?

Jellyfin is free, open source software, while Plex is proprietary software with a free tier. The Jellyfin documentation says it has no premium licences or features. Wikipedia adds that it began on 8 December 2018 as a fork of Emby, after Emby closed its source, and that it uses the GPLv2 licence.

By contrast, Plex works the other way round. The server software is free to start, but the extras sit behind a paid subscription called Plex Pass.

Table comparing Jellyfin and Plex: Jellyfin is GPLv2 free software with no paid tier, local accounts, free remote streaming and free hardware transcoding; Plex is proprietary with a free tier, Plex Pass from 6.99 dollars a month, a Plex account, remote streaming that needs a Plex Pass or Remote Watch Pass, and hardware transcoding as a Plex Pass feature.

Jellyfin vs Plex Cost: What Do You Pay on a Server?

Jellyfin costs nothing, but Plex costs a Plex Pass or a Remote Watch Pass as soon as anyone streams from outside your network, which on a rented server means every viewer. The server itself is the larger bill, so the Jellyfin vs Plex cost question is what each option adds on top of it.

Why Does Remote Streaming Matter on a Rented Server?

A server in a data centre is never on your home network, so every stream counts as remote. Plex began requiring a Plex Pass or a Remote Watch Pass for remote streaming of personal media on 29 April 2025, and has extended the rule to more apps since. If the server owner holds a Plex Pass, everyone the owner shares with streams at no extra charge.

Jellyfin’s remote access is free, but you set it up yourself, with a domain name and TLS in front of the server.

What Does Each Plex Option Cost?

A Plex Pass costs $6.99 a month, $69.99 a year, $249.99 for five years or $749.99 for life, and a Remote Watch Pass costs $2.99 a month for each viewer.

Table of costs in US dollars: Jellyfin is free for any number of viewers; Plex Pass costs 6.99 monthly, 69.99 yearly, 249.99 for five years or 749.99 for lifetime, which takes 10.7 years of yearly fees to break even; the Remote Watch Pass costs 2.99 a month or 29.99 a year per viewer and covers one account only.

Jellyfin vs Plex: What Do Five Years Cost?

Over five years, Plex costs between $249.99 and $749.99 for one server owner, depending on the plan, and Jellyfin costs nothing.

Horizontal bar chart of five-year costs for one server owner in US dollars: Plex Pass monthly over 60 payments costs 419.40, yearly over five payments costs 349.95, the five-year plan costs 249.99, the lifetime plan costs 749.99, and Jellyfin costs nothing.

Prices change often, so check Plex’s own page before you buy. For scale, a Swify Dedicated 1 costs €120 a month, or €1,440 a year, so the pass is a small part of the total. However, the real difference is that Jellyfin has no per-viewer or per-feature fee at all.

How Many Streams Can Each Server Plan Handle?

It depends on whether a stream plays as it is or gets converted: direct play is limited by the port, and transcoding is limited by the CPU. Both apps follow the same physics, so the Jellyfin vs Plex answer is nearly the same.

Jellyfin vs Plex Direct Play: How Many Streams Fit in One Port?

One 1 Gbps port carries about 100 direct-play streams of 1080p, 25 of 4K SDR and 20 of 4K HDR. A direct-play stream sends the file untouched, so it costs bandwidth and almost no CPU. Plex’s guidance uses 10 Mbps for a 1080p file, 40 Mbps for 4K SDR and 50 Mbps for 4K HDR, and every Swify plan has an unmetered 1 Gbps port.

Horizontal bar chart of direct-play streams on a 1 Gbps port at full line rate: about 100 streams of 1080p at 10 Mbps, 25 streams of 4K SDR at 40 Mbps and 20 streams of 4K HDR at 50 Mbps.

Jellyfin vs Plex Transcoding: How Many Streams Can the CPU Handle?

Depending on the plan, the CPU handles from 7 to 20 transcodes of 1080p, and from none to 3 of 4K. Plex’s own rule is about 2,000 PassMark points of CPU for each 1080p transcode, but 12,000 for a 4K SDR file and 17,000 for 4K HDR, but 12,000 for a 4K SDR file and 17,000 for 4K HDR. These figures come from Plex’s support page. Then divide a CPU’s benchmark by them to get a rough ceiling.

Also, the benchmark scores come from PassMark: 15,739 for the Xeon Gold 5215 and 23,189 for the Xeon Gold 6138. In addition, the dual-CPU plans score 23,889 and 40,845.

Table of software transcodes each Swify plan can run by Plex’s rule: Dedicated 1 and 2 with a Xeon Gold 5215 score 15,739 and run 7 transcodes of 1080p, 1 of 4K SDR and none of 4K HDR; Dedicated 3 and 4 with two of those CPUs score 23,889 with 11, 1 and 1; Dedicated 5 and 6 with a Xeon Gold 6138 score 23,189 with 11, 1 and 1; Dedicated 7 and 8 with two of those CPUs score 40,845 with 20, 3 and 2.

What Does Hardware Transcoding Change?

It frees the CPU, and that is where Jellyfin and Plex differ most. The Jellyfin documentation lists Intel Quick Sync, AMD and NVIDIA acceleration with no licence, while in Plex it is a Plex Pass feature. The chart then shows what the plans manage in software alone.

Horizontal bar chart of simultaneous 1080p software transcodes by plan: 7 for Dedicated 1 and 2, 11 for Dedicated 3 and 4, 11 for Dedicated 5 and 6 and 20 for Dedicated 7 and 8.

Jellyfin does not publish an equivalent table. However, both apps convert video in software when no graphics hardware is available, so treat the figures as a ballpark for either one. Meanwhile, the standard Swify plans have no graphics card, so the hardware advantage does not apply to them.

Jellyfin vs Plex: Which One Fits Your Server?

Choose Jellyfin for a server with many remote viewers and no per-viewer cost. Choose Plex if you already use its apps and are happy to hold a Plex Pass. On a CPU-only server, the Jellyfin vs Plex choice does not remove the cost of transcoding.

Table matching five situations to Jellyfin or Plex: many remote viewers with no budget for fees points to Jellyfin; existing Plex apps and libraries point to Plex with a Plex Pass; wanting no vendor account points to Jellyfin; many 4K HDR files that need converting favour neither on CPU alone; and mostly direct play of files your devices can play makes either app fine.

Can You Run Jellyfin and Plex on the Same Server?

Yes, because each one listens on its own port and can read the same media folders. Running both for a month is the cheapest Jellyfin vs Plex test, with your own files and your own viewers.

The cost is a little RAM and disk, and some CPU while each one scans the library. Also, keep the folders read-only for both, so neither can change your files. Finally, use the server only for media you own or have the right to share.

Jellyfin vs Plex: The Short Version

Neither needs the bigger server: the hardware depends on how the video is played, not on the app.

Jellyfin vs Plex is a choice between free software and a freemium service, on the same hardware. Jellyfin costs nothing, but Plex costs a Plex Pass once viewers are remote, which is always true on a rented server.

• Direct play is limited by the port: about 100 streams of 1080p on 1 Gbps.
• Transcoding is limited by the CPU: from 7 to 20 streams of 1080p across the Swify plans.
• A GPU, available on request, is what makes 4K transcoding practical.
