LinShare gives organizations a file sharing service they run themselves, where every upload, share, and download is accounted for instead of scattering across inboxes nobody can audit, retract, or find six months later. Your personal space keeps files organized and versioned, ready to share by link or email with the people who should have them and no one else. Teams work in shared spaces with roles, nested folders, and shared drives, so a project keeps one canonical copy instead of eleven emailed variants. Need files from someone outside? Send an upload request and they drop documents into a secure, expiring drop box without ever getting an account. Regular external collaborators become guests with restricted, time-limited accounts, and contact lists make recurring groups of recipients reusable in one click. Administrators see the whole picture in activity logs that trace every download, share, and change, while antivirus scanning checks files as they move through the system. Previews spare everyone the download-just-to-check dance, and directory integration with LDAP and OpenID Connect single sign-on means accounts follow your existing identity rules. Everything an administrator can click, automation can call through the REST API, and an MCP server even lets AI assistants manage files, shares, and guests on your behalf. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.
