Open Science Framework (OSF) is a free, web-based platform developed by the Center for Open Science that supports the entire research lifecycle from study design to publication. It enables researchers to manage projects, collaborate with team members, preregister studies, store and share data, and connect with other research tools through integrations. OSF promotes transparency and reproducibility in research by providing version control, persistent identifiers, and public sharing capabilities. The platform serves as a central hub for open science practices, making research more accessible and collaborative across disciplines.
