PsiTransfer is a self-hosted file sharing service for distributing files through a browser without requiring individual user accounts. It provides an alternative to hosted transfer services by keeping uploaded files on infrastructure managed by the server administrator. Users create upload buckets containing one or more files, then share the associated download link with recipients. The responsive interface works on desktop and mobile browsers.
The application supports large files and resumable transfers, reducing the need to restart uploads when a connection is interrupted. Administrators and uploaders can configure expiry behaviour, while recipients can download files individually or as compressed archives. PsiTransfer also provides optional password protection for upload access and download lists. Its design focuses on temporary file delivery rather than long-term synchronisation or collaborative document editing. Transfers are not end-to-end encrypted, so deployment security and appropriate access controls remain important.
This is free and open source software.
