About the Open Science Index

What is the Open Science Index?
A curated directory of scientific software — genomics, structural biology, chemistry, microscopy, neuroscience, medical imaging, astronomy, climate, physics, and more — filterable by domain, language, and format.
Which domains are covered?
Life sciences first (genomics, chemistry, structural biology, microscopy, neuroscience), plus medical imaging, astronomy, Earth/climate, physics, engineering, lab notebooks, and scientific databases.
Do you host the software?
No. Each card links to the project’s official site or GitHub. Install from the maintainers.
How is this different from an Awesome list?
Awesome lists are markdown dumps. This index is filterable by language, I/O, and maintenance status, and it sits next to Bibby’s writing tools.
