XBackBone

XBackBone is a self-hosted platform for uploading and sharing images, video, audio, PDFs, code and other files through short links with rich embeds. It supports inline previews for images, video, audio waveforms, PDFs and syntax-highlighted code, along with pastes and link shortening. Content-addressed storage de-duplicates uploads by content fingerprint, and per-resource visibility can be set to private or public with optional password protection and automatic expiration.

The platform includes a versioned REST API with token authentication and auto-generated OpenAPI documentation, modern authentication with registration, email verification, password reset, two-factor auth and passkeys, and user management with admin roles, per-user disk quotas and usage statistics. Storage backends include local disk, Amazon S3 and S3-compatible services, FTP and SFTP. A guided web installer sets up the database, storage and admin account from the browser, and runtime settings allow toggling sign-ups and the default theme without redeploying. It offers first-class ShareX uploader configuration, daisyUI themes, localization, and legacy import with transparent link redirection. XBackBone is released under the Apache 2.0 License.
