spotify_monitor

Powerful real-time tracker for Spotify friend music activity: monitor listening habits, auto-sync playback to your local client, detect skipped tracks and receive instant notifications for every beat your friends play.

🚀 Quick Install & Run

Python from PyPI

New to Python or unsure what is installed? Follow the Python install walkthrough first.

pip install spotify_monitor

Run setup wizard:

spotify_monitor --setup

Docker image - fastest container setup

macOS or Windows

Use a macOS shell or Windows PowerShell with a Docker-compatible runtime that provides the docker CLI.

docker run --rm --pull=always -it --init -v "${PWD}:/data:z" misiektoja/spotify-monitor:latest --setup

In Windows Command Prompt replace ${PWD} with %cd% above.

Linux

Run the container with your numeric user and group IDs (--user "$(id -u):$(id -g)" below). This lets the container write files that your host account can edit.

docker run --rm --pull=always -it --init --user "$(id -u):$(id -g)" -v "$PWD:/data:z" misiektoja/spotify-monitor:latest --setup

Docker Compose - shorter recurring commands

Download the Compose file:

curl -fsSLO https://raw.githubusercontent.com/misiektoja/spotify_monitor/refs/heads/main/docker-compose.yml

Linux container engine requires to export your numeric user ID and group ID so files created in the current directory belong to you instead of root.

export SPOTIFY_MONITOR_UID="$(id -u)"
export SPOTIFY_MONITOR_GID="$(id -g)"

Docker-compatible runtimes on macOS and Windows normally do not need these values.

Run setup wizard:

docker compose run --rm --pull=always spotify_monitor --setup

For the manual single-file method, optional extras and upgrade commands for every method, see Installation.

Before Monitoring

Spotify only shows a person's listening activity when both of these conditions are met:

1. The Spotify account used by Spotify Monitor follows the person you want to monitor.
2. That person has enabled listening activity sharing in Spotify.

The setup wizard checks whether the monitoring account follows the target. It can send the follow request after you confirm. To follow manually, open the target's profile in the Spotify desktop or mobile app. You can use Share > Copy link to profile and paste the complete link into the wizard. You do not need to extract the user ID. See Following the Monitored User.

Common Commands

Use Quick Install & Run above for first-time setup. The table uses PyPI commands. For manual script, direct Docker and Docker Compose equivalents, see Run Individual Commands.

Running the tool with no arguments offers the wizard if you have not saved a target. If a target is already saved, it starts monitoring that target.

For authentication, saved targets, configuration backups and setup recovery, see the full Setup & First Run guide.

For browser profiles, manual cookie extraction, Docker authentication, email and webhook setup, see Configuration. For notification choices, playback controls and output files, see Usage.
