Welcome to the official GitHub organization of Freva, the Free Evaluation System Framework — a powerful, modular, and open-source platform designed to unify data access, analysis tools, and reproducible workflows for Earth system science and beyond.
Freva is a community-driven software framework originally developed for the atmospheric and climate science communities. It provides:
- Unified data access across distributed storage systems and institutions
- A plugin system to integrate custom analysis tools
- Provenance tracking to ensure fully reproducible scientific workflows
- Multiple interfaces: Command-line, REST API, and Web UI
- Support for HPC environments, Docker/Podman, and Kubernetes
If you want to try out Freva locally, install our deployment tool and spin up an instance with just a few commands:
pip install freva-deployment
deploy-freva cmd --local📖 Full instructions in the Freva Deployment Documentation

- DKRZ – German Climate Computing Center
- MPI-M – Max Planck Institute for Meteorology
- JSC – Jülich Supercomputing Centre
