Why Jellyfin wins the media server migration battle

Jellyfin provides the most complete media server experience for users abandoning Plex in 2026. The software includes hardware transcoding, Live TV, DVR, and watched-status sync in the base product without any subscription requirements. Users migrating from Plex often face a massive price jump, as the lifetime Plex Pass rose from $249.99 to $749.99 on July 1. Jellyfin avoids this entirely by remaining free and open source. You should definitely make the switch if you want total control over your data.

The Jellyfin 10.11 release changed the backend by using an EF Core migration to consolidate the legacy library.db into a single unified jellyfin.db file. This change simplifies backups to one file and improves query performance for large libraries, though users with over 10,000 items might notice slower loading speeds during client-side enumeration. The 10.11 branch bundles FFmpeg 7.1, which improves AV1 hardware encoding quality for NVIDIA RTX 40 series and Intel Arc hardware. Jellyfin also supports hardware acceleration for Intel Quick Sync, NVIDIA NVDEC/NVENC, and AMD AMF.

Security flaws drive users away from Plex

Plex faces significant security pressure after releasing updates to address undisclosed flaws. On September 1, Plex urged users to update to Plex Media Server 1.43.3 and Plex Desktop 1.115.0 to patch several security issues. One fix, labeled PM-5766, prevents the TranscoderH264Options and TranscoderH264OptionsOverride preferences from being modified over the network. Another fix, PM-5763, addresses a potential vulnerability in the CompanionProxy. These updates arrived before the company assigned public CVE identifiers to the issues.

The attack surface for media servers remains large because they process complex media files. A critical vulnerability called PixelSmash, identified as CVE-2026-8461, affects the FFmpeg media framework used by many self-hosted servers. This flaw allows Remote Code Execution via a heap out-of-bounds write in the MagicYUV decoder. Security researchers demonstrated that uploading a 50 KB AVI file could achieve remote code execution on a Jellyfin media server through an automatic library scan. This vulnerability affects any system with the MagicYUV decoder enabled, which researchers found on every distribution package they tested before version 9.0.

Jellyfin simplifies the self-hosted life

Jellyfin works perfectly for local media streaming on any device. The server runs on a NAS, a mini PC, or a desktop, and users can access content on Android, iOS, Android TV, Fire TV, and Roku. While Plex handles remote access via its own infrastructure, Jellyfin requires you to manage your own networking through a VPN, port forwarding, or a reverse proxy like Caddy or Nginx. This setup demands more work from the user, but it keeps the connection private.

The Jellyfin client ecosystem is growing with specialized apps like Streamyfin for Android. Streamyfin allows users to manage server sessions, request media through Seerr/Jellyseerr, and configure Chromecast settings directly from a phone. The app provides more settings than other Jellyfin clients, including options to skip intros and manage media quality. The Jellyfin team also released Swiftfin 1.4 for Apple devices in January 2026, which overhauled navigation and routing.

The transition to Jellyfin 12.0 will likely introduce a new Web UI as the default for non-TV devices. This version aims to fix performance issues with large datasets and finalize the CSS variable support for themes. Will the new interface satisfy those who preferred the stability of the 10.11 branch? The software remains the best choice for those prioritizing privacy and zero subscriptions.
