LabKey Server is open source software that helps scientists manage, analyze, and share complex datasets. It supports tandem mass spectrometry, flow cytometry, assays for neutralizing antibodies, Luminex, observational studies, and secure, Web-based collaboration. The software is modular, configurable, and customizable. It can be installed in your institution on any modern hardware and operating system. It is designed to integrate with your existing systems, instruments, and work flows, and to be readily adapted by skilled programmers to novel methods of inquiry. The project is under active development by a team of professional software engineers and a community of active contributors. New versions are released about four times per year.
