Inspired by classic X11 window tree and attribute inspector utilities. Independent open-source Linux tool, not affiliated with any third-party vendor.
FEATURES • Crosshair Window Picker & Live XQueryTree Hierarchy: click any X11 or XWayland window with an interactive crosshair cursor or browse the full parent-child XQueryTree hierarchy with instant XID, WM_CLASS, and PID filters. • EWMH Atom & Property Decoder: enumerate attached X11 atoms via XListProperties and inspect WM_CLASS, _NET_WM_PID, _NET_WM_STATE, _NET_FRAME_EXTENTS, WM_PROTOCOLS, and WM_NORMAL_HINTS values in real time. • Live XClientMessageEvent & Geometry Controller: apply move_resize bounds, toggle above, shaded, sticky, fullscreen, or maximized states, adjust window opacity, activate windows, and export JSON or CSV inspection snapshots. • Bilingual UI: starts in English by default with instant Vietnamese toggle.

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
If you’re running Ubuntu 16.04 LTS (Xenial Xerus) or later, including Ubuntu 18.04 LTS (Bionic Beaver) and Ubuntu 20.04 LTS (Focal Fossa), you don’t need to do anything. Snap is already installed and ready to go.
For versions of Ubuntu between 14.04 LTS (Trusty Tahr) and 15.10 (Wily Werewolf), as well as Ubuntu flavours that don’t include snap by default, snap can be installed from the Ubuntu Software Centre by searching for snapd.
Alternatively, snapd can be installed from the command line:
sudo apt update
sudo apt install snapd
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
To install X11 Window Tree Inspector, simply use the following command:
sudo snap install x11-window-inspector
Browse and find snaps from the convenience of your desktop using the snap store snap.
