PyAppExec is a cross‑platform open-source launcher and installer that makes Python apps feel native. It locates or installs the required Python runtime, provisions an isolated virtual environment, installs your project’s pip requirements, and handles any external tools requirements or dependencies (e.g., FFmpeg) with version checks and auto-download/extract on Windows/macOS/Linux. The Qt-based installer can scaffold pyappexec.ini, copy/rename the launcher, and (on macOS) bundle a self-contained .app with icons. The optional run-time GUI captures logs, while CLI mode stays lean for automation. Config is driven by a simple INI per OS, so app IDs, entry points, requirements, and paths are declarative. PyAppExec also manages user-level caches/state, log rotation, and GUI suppression preferences letting you ship Python apps without asking end users to touch Python, virtualenvs, or package managers.
