Third-party client for self-hosted media servers

What to build

A lightweight, native cross-platform media client (desktop, mobile, Android/Apple TV) that connects to Plex, Jellyfin, and Emby servers through one unified app, aimed at self-hosted media server owners who no longer trust Plex's official apps to stay maintained.

Plex gutting its player team has spooked the self-hosted media community right as official apps are reportedly breaking (4K DoVi/HDR10 playback bugs), opening a window for a fast, no-bloat third-party client that isn't tied to Plex's roadmap.

Demand

Self-hosted media users (r/PleX, r/jellyfin, forums.plex.tv) are already reporting broken playback in current Plex apps and are anxious about further stagnation now that the player team is gone — they want a reliable alternative that isn't at the mercy of Plex's internal priorities.

• Hacker NewsEngagement

  Thread on 'Plex laid off the whole player team' reached 121 points and 89 comments on Hacker News, with high engagement at the source forum thread about a concurrent iOS/tvOS 4K DoVi/HDR10 playback bug.

  Signal flagged under the arbitrage opportunity category with no historical match found, indicating this is a fresh, un-milked opportunity rather than a recurring complaint.

Stack

• Flutter or Kotlin Multiplatform (single codebase for mobile/TV/desktop)
• Plex Media Server API
• Jellyfin API
• Emby API
• ExoPlayer / MPV for hardware-accelerated playback
• Jellyfin's open-source client code as a reference implementation

Solo + AI difficulty

The hard part is handling three different auth/transcoding/DRM schemes and getting smooth hardware-accelerated playback across desktop, mobile, and TV — that's a real multi-month effort even with AI pair-coding, not a weekend MVP. Easiest path: start with Jellyfin/Emby only (open APIs, no DRM friction) and add Plex support later once the UI shell and playback engine are solid; a usable single-platform (e.g. Android TV) MVP is realistic in 4-8 weeks solo.

Entry threshold

Low capital barrier; a solo developer can build a basic client on top of open Plex/Jellyfin APIs within weeks, though polishing playback across many device types (smart TVs, mobile, casting) takes sustained iteration.

Counter-signals & risks

• A player team layoff may not actually degrade app quality if Plex outsources the work, consolidates roles, or simply needs less active development on a mature codebase.

• Plex, Jellyfin, and Emby have different APIs, DRM/transcoding requirements, and auth schemes, making a genuinely unified client technically complex and expensive to maintain long-term.

• Established third-party clients like Infuse, Swiftfin, Finamp, and Kodi plugins already serve this niche, shrinking the opportunity window and raising competitive risk.

• No independent source corroborates the layoff claim beyond the single aggregated signal, so the underlying premise itself still carries verification risk.
