Notice: The OSF will be undergoing scheduled system maintenance and unavailable on Friday September 12, from 0:00 to 4:00 UTC, [Thursday September 11, from 8:00pm - 12:00pm EDT]. We thank you for your patience.

Effective 8/25/2025, we will be suspending submissions to this generalist server hosted by OSF Preprints. This does not affect the other community-run preprint services hosted by OSF Preprints. This suspension will allow us to review how the service is being used and moderated, and the impact it's having for advancing open scholarship. We will use this to inform our strategy for how best to position our services to support the research community. 

This is only a suspension for new submissions. We will continue hosting all existing preprints on this generalist server. Authors who need to revise their preprints will still be able to do so.


We understand this may be inconvenient for some. To help, here is a list of alternative preprint services on OSF and hosted on other platforms. If you have questions or need assistance, please contact our support team at support@cos.io. We will share updates as they are available on OSF Support.
