About

GSE Profiler is a GTK4 desktop application for managing, debugging, and profiling GNOME Shell extensions. It communicates with a bridge extension running inside gnome-shell to provide live function timing, a flame graph visualizer, a filterable log viewer, and a read-only state inspector. Features: - Extension manager with enable/disable toggle and state badges - Live log viewer with UUID filter, log-level filter, and full-text search - Flame graph profiler with per-function highlighting and call table - Inspector for browsing extension stateObj properties at runtime Why this app needs the listed permissions: - GNOME Shell extensions folder — to install the bridge extension and extensions fetched from GitHub. - User runtime folder gse-profiler — Unix socket used by the bridge extension to talk to the app. - System journal (read-only) — to show GNOME Shell and extension logs in the built-in log viewer. - org.gnome.Shell — to list, enable, disable and inspect installed extensions via the org.gnome.Shell.Extensions interface. - org.gnome.SessionManager — to log out the session after the bridge is installed or removed, so GNOME Shell picks up the change. - Network access — to download GNOME Shell extensions from GitHub on user request and to check whether an installed GitHub-sourced extension has a newer upstream commit. Used only for explicit user actions and a one-shot update check at app start; no telemetry or background traffic.
