Weirdly my Django SQL Dashboard project may fit the bill a bit here: you can build up a "dashboard" (which is a tiny bit notebook-like if you squint at it the right way) with multiple SQL queries on it, and save that either as a bookmark or as a "saved dashboard" with a URL.
In my own work I've been using it for the kind of things that I would normally use a Jupyter notebook for - gathering together research on problems I'm trying to solve.
