Crossbar.io comes with ready-to-run demos that show off different features of Crossbar.io.
The complete demo bundle is available as a Python package which you can install into your existing Crossbar.io installation and try yourself - see below.
For installation of Crossbar.io itself, please see the Getting Started.
The source-code for the demos can be found in the repository here and is open-source licensed under the Apache 2.0 license. This allows you to reuse the code even in commercial projects for use as starting points in your development.
