PsychNotebook was a web platform for students and scientists providing access to shareable and reproducible programming environments including RStudio and JupyterLab. It was developed and operated by Leibniz Institute for Psychology between 2019 and 2023.

In this talk I will review why PsychNotebook was built, which components we used and built ourselves, why we chose them and how they interacted with each other as well as how the platform was kept running. I will also discuss why, ultimately, the service was shut down and what can be learned from its technical and organizational design.
