SkyPortal is a web application that stores and interactively displays astronomical datasets for annotation, analysis, and discovery. It is designed to be modular and extensible, so it can be customized for various scienti c use cases. It is released under the Modi ed BSD license.

SkyPortal was designed with time-series survey data from the Zwicky Transient Facility, and eventually The Large Synoptic Survey Telescope, in mind.

By default, it aims to provide a useful, rich user experience, including light curves of named astronomical events/transients, spectra, live chat, and links to other surveys. But the intent, ultimately, is for the frontend to be modi ed to best suit the speci c scienti c problem at hand. The current UI/UX was inspired by that developed for the Palomar Transient Factory (PTF) Marshal (Law et al., 2009).
