A list of research software registries (also known as catalog, index, warehouse, repository, hub, platform, and other terms).

We define a registry as any publicly accessible website where research software can be registered, and that employs Search Engine Optimization such as the addition of metadata to help promote discovery of the research software that is published on the registry. Websites do not necessarily have to retain their own copies of the research software itself in order to be included in the list below.

• By country
