Open Science Framework (OSF), provided from the Center for Open Science (COS), is a free and open source project management tool that supports researchers throughout their entire project lifecycle in open science best practices. OSF promotes open, centralized workflows by enabling capture of different aspects and products of the research. As a flexible repository, it can store and archive research data, protocols, and materials.

Features & Specifications
Data Size and Format
