Keep CHARMM-GUI Free for Scientists Worldwide
Dear CHARMM-GUI Community,
I am writing to you not only as the developer of CHARMM-GUI, but as someone who has spent many years building and maintaining this resource for the scientific community. I need your help.
CHARMM-GUI now supports more than 70,000 users in more than 9,000 institutions from more than 140 countries worldwide. Every day, researchers rely on it to prepare complex molecular systems, accelerate simulations, and enable work that would otherwise take far more time and effort. For many groups, it has become a critical part of their research workflow. For many universities, it has been used as an essential tool for teaching. We also see fast-growing numbers of publications using CHARMM-GUI: Google Scholar Citations.
Since 2006, our team has continuously worked to expand capabilities, improve reliability, and respond to the needs of a rapidly evolving field. We maintain and update the platform, integrate new methods, support users, and ensure that it remains freely accessible. This has been a sustained effort — and one we are proud of. But we have reached a critical juncture.
The infrastructure currently supporting CHARMM-GUI is no longer sufficient for the scale of usage we are seeing. Without an upgrade, users will begin to experience slower performance and reduced availability, directly impacting ongoing research and teaching across many labs and universities worldwide.
If CHARMM-GUI has been part of your research, I ask you to consider supporting this effort. This is a direct investment in the continuity of a resource that many of you depend on. It will allow us to maintain performance, reduce interruptions, and continue supporting the scientific community that relies on CHARMM-GUI. Here is how you can help:
