XBackBone is a self-hosted file and media sharing platform that turns your own server into a tidy home for screenshots, clips, and PDFs, giving each file a clean short link with rich embeds for chat and social apps instead of expiring file-transfer links. Capture tools plug straight in: generate a ready-made uploader config for ShareX, ScreenCloud, ishare, Spectacle, Xerahs, the macOS Share sheet, or a CLI script, and new screenshots land on your instance with the link copied. The dashboard previews images, video, audio waveforms, PDFs, and syntax-highlighted code in the browser, and pastes plus link shortening cover text and URLs. Make any upload public or private, add a password, or set an expiration date, and identical files are stored once thanks to content fingerprinting. Storage stays flexible across local disk, Amazon S3 and compatible services, FTP, and SFTP. Admins manage users with roles, disk quotas, and usage statistics, review a searchable activity timeline, and toggle registrations or themes without redeploying. Accounts support email verification, password resets, two-factor codes, and passkeys. A guided web installer handles first setup, and admins can apply updates from the browser. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. Apache-2.0 licensed.
