Sabela – A Reactive Notebook for Haskell

Sabela is a reactive notebook for Haskell where cells automatically respond to each other on change, enabling interactive and exploratory programming. Initially designed as a data analysis tool, it has proven valuable for pedagogy, making it useful for educators and learners who want to experiment with Haskell code in a live, responsive environment. Its interest lies in bringing the reactive notebook paradigm—common in languages like Python—to Haskell, bridging the gap between functional programming and interactive development.
