Ambry is a personal audiobook streaming server that keeps a collection you own on hardware you control, ready to stream to any browser or phone. Upload your audiobook files once, and the library becomes streamable to any device through a browser or the native mobile application. The server reads durations, tags, and chapter markers straight from the audio files, so a long novel arrives with its structure intact instead of as one anonymous ten-hour blob, and the original files are served untouched. First boot walks you through creating the initial administrator account, after which the instance restarts ready for listening. Households can open registration to family members or close it entirely, keeping the library an invitation-only shelf. Forgotten passwords and registration messages go out through the configured mail provider, so account recovery works without manual intervention. The collection itself lives in PostgreSQL with uploads on a persistent volume, and the whole service runs from a container image on a configurable port. Put a commute listen on your phone, a history title on a kitchen tablet, and a shared family library behind one address, all served from hardware you control. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.
