GitHub - glocker-app/glocker: Distraction blocker and usage tracker for Linux: blocks sites, content and apps on a schedule, hard to switch off, with optional accountability alerts

A distraction blocker for Linux. It blocks sites and apps on a schedule, makes turning it off slow and deliberate, and logs your usage.

Features

Site blocking through /etc/hosts, always or during set windows, with logged temporary unblocks.
Program blocking: listed programs are killed during their windows.
Sudo window: sudo only works during the hours you choose (Debian, Ubuntu, Fedora, Omarchy, Arch).
Browser extension for Firefox and Chrome that blocks pages by keyword.
Screen lock after repeated violations (glocklock).
Slow uninstall: a stated reason and a typing challenge.
Usage tracking of the focused window (X11, GNOME, KDE Plasma, Hyprland), viewable in the glockpeek dashboard.

On amd64:

curl -fsSL https://glockerapp.com/glocker-installer.sh | sh
glocker -status

To change the config afterwards, use the built-in editor inside your sudo window (without sudo it opens read-only):

Or edit the file by hand and restart:

sudoedit /etc/glocker/config.yaml
sudo systemctl restart glocker

To build from source (Go 1.26+, python3 for the blocklist script):

make init            # write conf/conf.yaml from the sample
$EDITOR conf/conf.yaml
make full-install

Uninstall with sudo glocker -uninstall "reason".

Requires Linux with systemd and root to install. The content-blocking extension needs Firefox or Chrome/Chromium.
