And much more!

Try it without installation with Binder or JupyterLite:

| --- | --- | --- |
| Binder | [![Binder](https://mybinder.org/badge_logo.svg)](https://mybinder.org/v2/gh/jupyterlab/plugin-playground/main?urlpath=lab) | [![Binder Notebook v7](https://mybinder.org/badge_logo.svg)](https://mybinder.org/v2/gh/jupyterlab/plugin-playground/main?urlpath=tree) |
| JupyterLite | [![JupyterLite](https://jupyterlite.rtfd.io/en/latest/_static/badge-launch.svg)](https://jupyterlab-plugin-playground.readthedocs.io/en/latest/lite/lab/) | [![JupyterLite Notebook v7](https://jupyterlite.rtfd.io/en/latest/_static/badge-launch.svg)](https://jupyterlab-plugin-playground.readthedocs.io/en/latest/lite/tree/) |

We are still polishing the UX and fixing some minor bugs, but we will likely move to beta and RC quick - with a lot depending on community feedback.

I would be super interested in feedback from you all!
