Client file sharing, rebuilt from the ground up: a private area per client, resumable uploads, folders, groups and categories, sharing with expiry dates and download limits, comments, file versions, an activity log, a REST API, and sixteen languages. This repository begins here. ProjectSend 2 was developed privately, and that development history is not published — the previous generation remains available, with its own history, at projectsend/legacy. Free software under the GNU General Public License v2, or (at your option) any later version.
