dbus-fast
A faster version of dbus-next
Decision gist · record as of 2026-08-14
Yes. dbus-fast is actively maintained, has no runtime dependencies, supports current Python versions, carries permissive MIT licensing, and fills a genuine need for performant D-Bus integration on Linux. Install friction is modest (optional Cython extension with pure-Python fallback). Suitable for production use in desktop and system integration projects.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires a running D-Bus daemon (typically present on Linux desktop/mobile systems); not functional on systems without D-Bus.
- Medium install friction due to optional Cython extension bundled in wheels; pure-Python fallback available via SKIP_CYTHON=1.
- Actively maintained with recent commits and no runtime dependencies.

What it is and what it does
dbus-fast is a D-Bus library for Python that lets you communicate with system services and desktop environments on Linux. It provides three layers: a high-level client interface for calling methods and listening to signals on remote services, a high-level service interface for exporting your own D-Bus objects with decorated methods and properties, and a low-level message API for direct D-Bus protocol work. The library emphasizes performance through an optional Cython extension for marshalling, supports multiple I/O backends including asyncio and GLib, and requires zero runtime dependencies in pure-Python mode.
Typical use cases include desktop application integration (implementing standard interfaces like MPRIS for media players), scripting system services, and building custom D-Bus interfaces for inter-process communication. The library targets modern Python versions and aims for complete D-Bus type system coverage without type guessing.
Use it for
- Control media players or other desktop services via standard D-Bus interfaces like MPRIS
- Export custom D-Bus services from Python applications for other processes to call
- Write system administration scripts that interact with D-Bus services like NetworkManager or systemd
- Integrate Python applications into Linux desktop environments via D-Bus standard interfaces
- Build asyncio-based D-Bus clients for non-blocking GUI application development
