SkySend is a self-hostable, end-to-end encrypted file and note sharing service for sending files and notes without exposing their contents to the server. It is designed around ciphertext-only handling on the server side, and its copy says that no accounts or tracking are involved.
Files and notes are encrypted client-side with AES-256-GCM before upload, so the server only receives ciphertext. The decryption key stays in the share link’s URL fragment, which browsers do not send to servers by design. SkySend also describes this as zero-knowledge, and says that even the person running an instance cannot read what is shared through it. The page also presents AES-256-GCM and Argon2id as documented standards rather than a custom cipher.
The service is self-hostable and the page includes a Docker example for running it. It also mentions public SkySend instances that can be used right away, along with their live limits. Other listed features include a CLI and TUI client, 13 languages, 2 storage backends, and support for files, notes, and automation.
SkySend is released as open source under the AGPL-3.0 license. The page links to GitHub and documentation, and its wording identifies the project as an end-to-end encrypted file and note sharing tool.
