If you’ve ever gone looking for a more advanced, or use-case-specific Crazyflie example (something beyond the basic single-feature ones), you’ve probably ended up digging through the cflib and crazyflie-firmware example folders. That’s about to change.
We’ve created a new repository: crazyflie-demos. It’s a dedicated place where both us at Bitcraze and the broader community can host self-contained, well-described Crazyflie demos.
Why a new repository?
The examples in the core Bitcraze repositories were meant to be kept focused: demonstrating one feature, one API, or one subsystem at a time. But real demos tend to grow beyond that pretty quickly. Once you start combining positioning systems, swarming, custom firmware apps, external sensors, or other integrations, things stop fitting naturally into the firmware or library repos.
crazyflie-demos gives those larger, more practical examples a proper home, and finally provides a good answer to the question: “where should I put this cool thing I built?”
Why not just a folder of examples?
We want to avoid the fate of some older example collections that gradually turned into an unmaintained pile of half-working demos and missing context.
The goal with crazyflie-demos is that every demo should be properly documented and actually runnable. That means clear descriptions, listed dependencies, and enough context to understand what’s going on without digging through source code for an hour.
Another important part is reproducibility: each demo is self-contained and uses pinned dependencies, so an example you clone two years from now should still work.
What’s in there already?
The repository is organized by demo type:
- scripts/cflib: Host-side Python scripts using crazyflie-lib-python, covering the full Crazyflie API.
- scripts/rust: Rust demos using crazyflie-lib-rs, showcasing its high-performance and native async support.
- scripts/cflib2: Early demos for our new Python library, crazyflie-lib-python-v2, built on top of the Rust library. cflib2 doesn’t have a release yet, but we’re already writing demos for it to test the API and the performance.
- firmware: Out-of-tree firmware apps that are flashed directly to the Crazyflie. Each demo carries its own crazyflie-firmware submodule so you’re always building against the right version.
- hybrid: Demos that combine onboard firmware with a host-side script working together.
A place to share your work
A big motivation behind crazyflie-demos is making it easier to share work with the community.
If you’ve built something useful, or just a fun experiment using our products, this is the place for it. Not everything needs to live in its own repository or branch. A well-described demo here makes it easier for others to find, understand, and build on your work, and most importantly, to get inspired by it.
We’ll also be using this repository as the go-to reference whenever people ask for more use-case-specific examples, so good demos here will naturally help more people discover what’s possible with the Crazyflie ecosystem.
