The ESO Data Processing System (EDPS) is a new system to run the ESO data reduction pipelines. It will replace EsoReflex as the recommended way to process ESO raw data in 2026. An Alpha version of the Graphical User Interface has been released and can be used to run ESO pipelines for any of the currently active VLT instruments. While the documentation is still incomplete, the software itself is fully functional. It is significantly more performant than EsoReflex, and in some cases delivers better results due to better data organisation, default setup or workflow. ESO encourages the use of the EDPS GUI for new data reduction projects. Requests for support or any feedback can be submitted via the ESO support page.
