Open-Source Alternatives to WeTransfer

Send is an end-to-end encrypted file sharing service that encrypts files on the sender's device before upload, ensuring the server never sees plaintext content. It generates secure download links that are designed for single use, automatically removing access after the first successful download, and associates each share with a time-limited access token that expires after a set duration. The service operates without requiring user accounts, lowering friction for ephemeral sharing, and uses cryptographic key derivation to generate decryption keys from the download URL, eliminating server-side

Send is a self-hosted file transfer service designed for end-to-end encrypted file sharing. It provides a privacy-focused data transfer solution and ephemeral file storage where uploaded content is automatically deleted after a specified number of downloads or a set amount of time. The service ensures private file sharing by utilizing client-side encryption to protect data before it is uploaded. Decryption keys are distributed to recipients via URL hash fragments to ensure the server never has access to the keys. The platform supports encrypted data transfer and temporary file hosting.

Linsa.io is an end-to-end encrypted cloud storage service and zero-knowledge data vault. It functions as a private content sharing platform that encrypts files and data on the client side, ensuring only the owner can access the stored content. The project employs a local-first approach, processing data updates and encryption on the local device before syncing encrypted blobs to a remote persistence layer. It uses a zero-knowledge architecture where the service provider cannot access decryption keys or view the plaintext content of stored files. The platform provides capabilities for private

Microbin is a self-hosted file sharing application and encrypted pastebin written in Rust. It provides a platform for hosting text snippets and binary files via unique links, functioning as both a secure file drop and a URL shortener. The system features client-side end-to-end encryption, ensuring the server does not see plaintext data before it is transmitted. It includes secure postbox portals for collecting documents from external clients and supports password-protected access control to restrict content visibility. The platform manages the upload lifecycle through time and view-based exp

KodExplorer is a web-based file manager and remote server administration tool that provides a desktop-like interface for organizing and managing files in a browser.
