Navidrome is written in Go and released under GPL v3. It opens a Subsonic interface so a hundred and two existing clients connect, adds transcoding, several libraries and plug-ins, and the current release is 0.64.2.

A self-hosted open media server that files films, series and music into a library for playback on many devices, supports server-side transcoding and plugins, and can give each person in the household their own account; the current release is 12.2.

An open media centre for the living room that scans local films and music into one library with artwork and descriptions, designed for a remote control on the sofa, and extended through community add-ons; the current stable release is 21.3 Omega.

mpv is a free open source cross-platform media player built around the command line, with a deliberately minimal interface and video output covering colour management, interpolation and HDR. Version 0.41.0 makes gpu-next the default.

Anyone still collecting local music in the streaming era cares about two things, sound quality and order. Strawberry plays lossless files without complaint and organises a library by album, artist, genre and year, however many thousands of records it holds.

IINA wraps the mpv engine in a native macOS interface, so awkward containers and high bitrate 4K files open without codec packs while dark mode, picture in picture and trackpad gestures still work as expected.

Subtitle Edit is a free, open-source subtitle editor that has been maintained since 2001, now cross-platform, with Whisper transcription and OCR for burned-in text.

An open-source utility that detects speech in a video audio track and shifts a mismatched subtitle file back into place, correcting frame rate drift as well, usable from the command line or in a browser page.

An open-source player built for watching a series rather than opening a single file: local video plays with a danmaku track overlaid, subtitles load alongside, the interface stays out of the way, and it runs on five platforms.
