What is it?

SFTPGo is a configurable file transfer server that exposes storage through the protocols many teams already use: SFTP, FTP/S, HTTP/S and WebDAV. Users connect with standard clients, while files are stored on the local filesystem, an encrypted local filesystem, S3-compatible object storage, Google Cloud Storage, Azure Blob Storage, or another SFTP server.

It is aimed at exchanging files internally or with business partners without changing existing workflows. The project includes a web administration interface and a user-facing web client, and it supports multi-factor authentication, Prometheus metrics, PROXY protocol, and data-at-rest encryption. Docker images and portable builds are available.

The Community edition is licensed under AGPL-3.0 and includes the core protocols, storage backends and web interfaces. A commercial Enterprise edition adds features such as high-availability tuning, virtual folders for archiving, and email attachment ingestion.
