Zasper is a high-performance IDE inspired by Jupyter, designed for massive concurrency with minimal memory usage and exceptional speed. It uses one fourth of RAM and CPU compared to JupyterLab. Developed by Prasun Anand, Zasper was created to work seamlessly on local machines, utilizing available resources efficiently. Built with Go for enhanced concurrency and performance, Zasper is available as both an Electron app and web app. Future development aims to support custom data apps and easier integration with existing tools. Licensed under AGPL-3.0, Zasper offers a free and open-source alternative to proprietary tools like Databricks Notebooks and Deepnote Notebooks.
