We are hoping for pyodide integration soon, which would allow fastplotlib to be run strictly in the browser!

Thanks. That will be very cool.

In the browser only jupyter for now, you can use voila to make a server based application using jupyter: https://github.com/voila-dashboards/voila

As Caitlin pointed out below pyodide is a future goal.

This is very nice. But thinking more along the lines of, can I embed a single interactive widget in a blog post.

Not today, it requires wgpu-py to support running on WASM / pyodide, which it doesn't yet (unfortunately)
