This year marks the 10th anniversary of KEEPER, the Max Planck Society’s secure service for storing, sharing, and managing research data. Over the past decade, KEEPER has grown into a central component of the MPG’s digital research infrastructure, supporting thousands of researchers across its institutes and disciplines.
Developed and operated by the Max Planck Digital Library, as part of Max Planck Information and Technology, KEEPER provides researchers with a secure, institutionally hosted alternative to commercial cloud storage platforms. Users can also enrich archived data with metadata, obtain a Cared Data Certificate for good scientific practice, or even assign a DOI to a dataset to make it citable within research outputs. With generous storage, cross-platform synchronization, version control, and powerful collaboration features, it has become an essential tool for scientific workflows across the Max Planck Society.

A Decade of KEEPER
Reflecting on the milestone, Vladislav Makarenko, developer of KEEPER, emphasizes the project’s core mission: supporting the scientific community of the Max Planck Society.
“A decade of KEEPER—for and with the scientists of Max Planck Society. It gives me great joy to have been involved from the very beginning and to be part of a project that helps researchers in a tangible way. Congratulations!”
Friederike Kleinfercher, developer of KEEPER, recalls its origin and purpose: “Our mission from the MPDL 2015 Research Coordinators Symposium: a tool for the long-term archiving of research data. The result was KEEPER: secure, sustainable, and efficient storage for MPG scientists—seamlessly usable in your everyday work, without media disruptions and without extra steps.”

MPG Researchers Celebrate KEEPER
For KEEPER’s 10th anniversary, many Directors and researchers of the MPG sent their congratulations, reflecting on its value in supporting research and collaboration.
A System Built for Research Needs
According to Dietmar Harhoff, Director at the Max Planck Institute for Innovation and Competition, KEEPER’s success lies in how well it fits the research environment:
“A system that perfectly suits the needs of our research.”
Researchers also value KEEPER as a trusted alternative to commercial file-sharing platforms.
“KEEPER has everything to be a suitable Dropbox replacement (sharing, syncing, and apps for every platform), but with the additional benefits of having 1TB of free storage, hosted on our own servers.”
— Erik Buunk, Data Science Officer at the Max Planck Institute for Innovation and Competition
Enabling Secure and Efficient Collaboration
For many research groups, KEEPER plays a key role in organizing complex datasets and collaborating with partners worldwide.
“KEEPER has become an indispensable platform for managing and organizing our scientific data, providing secure storage and a well-structured workflow. It significantly enhances collaboration by making data sharing with partners seamless, efficient, and dependable.”
— Knut Finstermeier, Head of Bioinformatics at the Max Planck Unit for the Science of Pathogens
At the Max Planck Institute for Polymer Research, KEEPER supports large-scale collaborative projects.
“With KEEPER, we can organize complex, data-intensive projects across groups and institutes and still be confident that our final datasets are properly curated, citable, and stored within the Max Planck Society.”
— Mischa Bonn, Director at the Max Planck Institute for Polymer Research
“Having recently joined the MPI for Polymer Research, we immediately transitioned to using KEEPER for our collaborative work and have found it both efficient and user-friendly.”
— Frauke Gräter, Director at the Max Planck Institute for Polymer Research
Voices from different institutes describe KEEPER as their digital backbone for collaboration, data sharing, and long-term archiving.
“KEEPER has become an essential part of how we organize research in our lab. It helps us keep track of projects, streamline communication within the team, and share data efficiently. It also plays a crucial role in preserving knowledge across generations of lab members, which is essential for maintaining high scientific standards over time.”
— Yen-Ping Hsueh, Director at the Max Planck Institute for Biology Tübingen
“KEEPER has become our digital backbone. At the Scientific Coordination Office of the Max Planck Institute for Intelligent Systems, we rely on KEEPER for internal and external collaboration, secure archiving, and much more, making it an essential part of our project management.”
— Matthias Tröndle, Head of Scientific Coordination Office at the Max Planck Institute for Intelligent Systems
“We use KEEPER for all daily work routines in the photographic collection, from keeping track of work in spreadsheets to documenting meetings, from revising documents to preparing slides, from archiving reports from HPC jobs to sharing data deliveries with our users. Sharing and collaboratively working on files and folders feels very easy and secure with all we need to do our work individually and in the team without any other alternative. KEEPER is integrated in all our workflows and thus a vital part of our toolset.”
— Pietro Liuzzo, Senior Information Scientist at Bibliotheca Hertziana, Max Planck Institute of Art History
Everyday Tools that Make a Difference
Beyond large-scale collaboration, researchers appreciate practical features that make daily work easier.
“The new wiki feature will revolutionize our work. It's exactly what we have been waiting for.”
— Michael Rose, Senior Research Fellow at the Max Planck Institute for Innovation and Competition
“KEEPER is completely integrated in my workflow: I use the SeaDrive folder on my laptop as my work folder and everything is synced all the time. This is extremely useful when working with collaborators, as I can easily invite them and know they are working on the latest version. Any mishap, and the versioning saves the day. Once a project is closed, you can archive it and generate a DOI. KEEPER has become a stable and indispensable partner in my daily work.”
— Elisa Bastianello, Digital Publications Manager at Bibliotheca Hertziana, Max-Planck Institute for Art History
Looking Ahead
As KEEPER enters its second decade, the platform continues to evolve to meet the growing demands of data-intensive science.
“I’m still exploring the full range of what KEEPER can do, and I truly appreciate the role it plays in supporting our research ecosystem. Happy 10 years!”
— Veit Schwab, Scientific Coordinator at the Max Planck Institute of Psychiatry
Over the past decade, KEEPER has helped Max Planck researchers manage their data securely, efficiently, and sustainably—from individual file sharing to large-scale collaborations.

We are excited to announce that
The Max Planck Society is thrilled to mark the 25th anniversary of its Scientific Information Provision ("Literatur-Grundversorgung"), the core service provided by the Max Planck Digital Library that gives our researchers near-universal access to the literature they need to advance their work, while ensuring their results reach a wide audience.
But the significance of the Scientific Information Provision extends beyond mere convenience. It reflects a larger mission: not just to access existing knowledge, but to amplify the research produced by the Max Planck Society and make it accessible to as many people as possible. This vision aligns with the goals of the
