A curated list of open source software for any stage of a rigorous, systematic research project — not limited to any single discipline or method.
This list is method- and discipline-agnostic. If a tool is open source and supports some part of the research lifecycle — collecting data, managing it, analyzing it, making the work reproducible, writing it up, or reviewing existing literature — it belongs here. Social sciences, natural sciences, health sciences, digital humanities: all welcome, as long as the software itself is open source.
