Dendro

Dendro is a fast, modern graphical package manager and interactive dependency tree visualizer built natively for Fedora Linux (RPM / DNF). Designed for both power users and system administrators, Dendro empowers users to explore complex package relationships, query reverse dependencies, safely detect orphans, inspect installed package files, and simulate administrative transactions.

Key Features: • Multi-Level Interactive Dependency Tree: Visually explore full dependency graphs (direct requirements, sub-dependencies, and virtual RPM capabilities) with DAG cycle detection. • Reverse Dependency Explorer ("What Requires This?"): Query which packages depend on a specific shared library before removing it, preventing accidental system breakage. • Pre-Flight Dry-Run & Safety Guard: Simulates queued changes (--assumeno) to warn users immediately if essential Fedora core components (kernel, systemd, glibc, gnome-shell) might be accidentally removed. • Live Package File Inspector: Browse installed files (/bin, /etc, /usr) for any package with real-time path search and filtering. • DNF History & Rollback: View past system update/install transactions and safely revert changes with a one-click rollback. • Smart 20+ Categorization Engine: Automatically organizes packages into Desktop Apps, CLI Tools, Language Runtimes (Python, Rust, JVM, Node.js), Kernel Modules, Systemd Services, and Leaf Orphans. • Native Polkit Elevation: Executes operations securely with standard system authentication (pkexec dnf5/dnf) and real-time terminal progress streaming.
