OSF Backupper

OSF access token (optional)

Works without one. A token (read scope is enough) raises your limit from 100 to 10,000 requests a day and skips the CORS proxy below.

Shows public projects, or your own private ones too if you paste your own token. Always open your downloads afterwards to check they worked.
