How can it be free? How will OSF be useful to my research? What is a registration? Get your questions about OSF answered here.
OSF is maintained and developed by the Center for Open Science (COS), a 501(c)3 non-profit organization. COS is supported through grants from a variety of supporters, including federal agencies, private foundations, and commercial entities. Read more about our finances.
COS established a $250,000 preservation fund for hosted data in the event that COS had to curtail or close its offices. If activated, the preservation fund will preserve and maintain read access to hosted data. This fund is sufficient for 50+ years of read access hosting at present costs. COS will incorporate growth of the preservation fund as part of its funding model as data storage scales. For information about OSF backups and technical preservation details, see the OSF Backup and Preservation Policy.
OSF integrates with the scientist's daily workflow. OSF helps document and archive study designs, materials, and data. OSF facilitates sharing of materials and data within a laboratory or across laboratories. OSF also facilitates transparency of laboratory research and provides a network design that details and credits individual contributions for all aspects of the research process. To see how it works, read our Guides.

Security and privacy
You’re always welcome to deactivate or delete your account. You should be aware that information that you've shared with others or that others have copied may also remain visible after you have closed your account or deleted the information from your own profile. In addition, you may not be able to access, correct, or eliminate any information about you that other users have copied or exported out of the Websites, because this information may not be in our organization's control. Your public profile may be displayed in search engine results.
Security is extremely important for OSF. When you sign up and create a password, your password is not recorded. Instead, we store a bcrypt hash of your password. This is a computation on your password that cannot be reversed but is the same every time it is computed from your password. This provides extra security. No one but you can know your password. When you click "Forgot your password," OSF sends you a new random password because it neither stores nor has the ability to compute your password.
Transfer of data to OSF Storage is encrypted with SSL (external storage add-ons may have their own policies). Data at rest is encrypted on OSF Storage. You can also use the Amazon S3 add-on and implement server-side encryption on S3.
OSF Storage uses Google Cloud for both active and archival storage. Files uploaded to OSF Storage are stored in various storage locations, configurable per user. We keep MD5 hashes for files and use cyclic redundancy checks to prevent and mitigate any data corruption. File backups are hosted in regional coldline buckets, and there are twice daily backup jobs performed. Please refer to Google Cloud documentation for details about the other robustness features Google Cloud provides.
The OSF database is backed up via streaming replication 24 hours a day, and incremental restore points are made twice daily. Further, the OSF database is maintained in encrypted snapshots for an additional 60 days. Database backups are verified monthly.
Operational data for other OSF services are backed up in primary cloud file storage for 60 days.
Logs are primarily stored in Google Cloud cold storage indefinitely. In certain cases a third- party aggregation service is used for up to 90 days, then backed up to Amazon S3 indefinitely.
Unfortunately, no. When a user deletes a file or project from OSF, access to this content is removed for all users.
OSF is designed to support both private and public workflows. You can keep projects, or individual components of projects, private so that only your project collaborators have access to them.
OSF is not HIPAA compliant. If you use a HIPAA-compliant storage provider that is available as an OSF add-on, we recommend using that service connected to your OSF project to meet your HIPAA requirements. Please refer to your institutional policies regarding specific security requirements for your research.
The United States is the default storage location for OSF Storage. You can set a global storage location for newly created projects going forward; different locations can be set on a per-project basis upon creation. Setting a global storage location is not retroactive: All existing projects will continue to be stored in the United States. As of now, the storage locations available are
- United States
- Canada - Montréal
- Germany - Frankfurt
- Australia - Sydney
Files connected to third-party storage add-ons are not stored or backed up on OSF; please refer to the provider's server locations for information on where this content is stored.
OSF supports many third-party add-ons. For storage, you can connect to Amazon S3, Bitbucket, Box, Dataverse, Dropbox, Figshare, Github, GitLab, Google Drive, OneDrive, and Owncloud. For citation management, you can connect to Mendeley and Zotero. OSF also has its own default storage add-on, OSF Storage, if you choose not to connect to any third-party add-ons. Please refer to the Add-ons section of our Guides for more information on how to use add-ons.
Currently, there is no applied limit on storage per project, and there is no applied overall cap on the amount of OSF Storage per user. Each project is created with a default OSF Storage enabled. Each project can additionally have any number of add-ons connected to their project to extend its usability and allow access to existing data/materials.
The limit of add-on storage options varies by provider. We recommend users utilize the storage option that is ideal for their data (e.g., with respect to accessibility or security) and connect that service to their OSF project(s) rather than transfer the data to OSF storage.

Log in to OSF with the email address and password of the account you created, and there will be a link to resend the confirmation email.
From your "Account Settings" page, you can add additional email addresses to your account, and select which of these is your primary email address. Any of these emails can be used to log in to OSF.
Log in to the account you wish to keep and navigate to your "Account Settings" page. There, enter the email address associated with your other OSF account. You will receive a confirmation link via email. Clicking the link will merge the projects and components into one account.
A folder can be used to organize files within a project or component - just like a folder on your own computer groups files together. A component is like a sub-project to help you organize different parts of your research. Components have their own privacy and sharing settings as well as their own unique, persistent identifiers for citation, and their own wiki and add-ons. You can also register a component on its own, without registering the parent project.
To apply a license to your OSF project, visit the project's "Overview" page and select one from the "License picker" in the top left of the page below the project's description. You can select from a variety of commonly used licenses or upload your own.
DOIs are available for public projects and registrations. To get a DOI, first create a project or registration. Then click the "Create DOI" link, located in the top left of the page below the project title. A DOI will be automatically created.
To delete a project or component, navigate to the project or component and click on Settings in the gray navigation bar. There you will see a red Delete button. If the project or component has nested components, you must delete the nested components before you can delete the parent project or component.
A globally unique identifier, or GUID, is a unique string only assigned to one object on OSF. All files, projects, registrations and users on OSF receive a GUID. Privacy settings of the project, component, or registration dictate who can see the metadata about files, projects, components, or registrations. If a file is deleted, the GUID will always resolve to a page that provides metadata about the removed file (file name, storage provider, if the deletion occurred on OSF or on an add-on service, name/GUID of user who deleted the file, and timestamp of file deletion). For projects, components, registrations and users the GUID will resolve and inform that the content has been removed. Non-deleted or withdrawn files, links, and metadata are persistent as described above.
A registration is a frozen version of your project that can never be edited or deleted, but you can issue a withdrawal of it later, leaving behind basic metadata. The project can continue to be edited and updated, providing you the option to register your project at different points throughout the research cycle.
When you create the registration, you have the option of either making it public immediately or making it private for up to four years through an embargo. A registration is useful for certifying what you did in a project in advance of data analysis, or for confirming the exact state of the project at important points of the lifecycle, such as manuscript submission or the onset of data collection. Read more about registrations here.
Registering is an optional feature of OSF.
You can rename a project or component by clicking on its title in the top left of the project or component "Overview" page.
You can move files between components and add-ons (provided the components and add-ons are a part of the same project) by simply dragging and dropping from within the "Files" section on the project "Overview" page or in the "Files" tab via the project navigation bar. The Dataverse add-on does not currently support this functionality.
You may have been removed from the project by one of the administrators. You can get in touch with one of the administrators to ask if you were deleted and whether they can re-add you to the project.
Yes, send us an email with your DOI and the new location of your materials and we will update the URL associated with your DOI.
You can view, download, delete, and rename any files uploaded into OSF Storage. Plain text files can be edited in your browser. All files are assigned unique, persistent identifiers, suitable for use in citations.
Files in third party storage add-ons might have restrictions on renaming or deleting.
The best way to create a lab or organizational group on the OSF is to create a project for that group. Then, individual projects within the lab can either be organized into components of the lab project or into their own projects which are linked to the lab group project. For an example, check out the Reproducibility Project: Psychology.
You may be in the project rather than the registration. To go to your registration, open the project that you registered, and click the Registrations tab in the navigation bar. You'll be taken to the "Registrations" page, where all registrations associated with the project will be listed. Select the registration you want to view from the list.
Alternatively, you can access all your registrations by clicking the My Projects tab in the navigation bar, then clicking All my registrations from the sidebar, and selecting the registration from the list.
It isn't possible to move projects to be nested below one another at this time. However, you can simulate this structure by adding links to the desired projects from the main project, and the links will appear on the project page under "Components" — see our help guide for step-by-step instructions.
You can search for content using the main search feature in the navigation bar. Simply click the Search tab, and type in your search criteria using Lucene search syntax. For example:
You can then filter results using the sidebar options, e.g. projects, files, users, preprints, registrations, etc.

After submitting your registration, you would have received an email titled "Registration pending for one of your projects" in which there will be a link to approve your registration. If you didn't receive this email, try checking your spam or quarantine folders to see if the email was sent there.
All admins on the registration can approve the registration by clicking the link. If an admin disapproves the registration, the registration will be canceled. If the admins do not take action via the email, the registration will become registered automatically after 48 hours.
The 48-hour cycle runs from midnight on the day you submitted the registration to midnight on the second day. Try checking back at midnight.
If you need to register before midnight, you would have received an email titled "Registration pending for one of your projects" in which there will be a link to approve your registration. If you can't find this email, try checking your spam or quarantine folders to see if the email was sent there.
Try checking your spam and quarantine folders to see if the email was sent there. If you still don't find it, please submit a request to user support, and we will help you.
The privacy settings of projects and registrations are independent from each other. Making your project public will not affect the embargo on the registrations. The only way to make a registration public is to actively end the embargo.
Once a registration has become public, it cannot be made private. However, if you need to, you can create a new, embargoed registration, and then withdraw the original one. For transparency best practices, please provide a link to the new registration in the justification for withdrawal and provide a brief explanation of the reason for withdrawal.
