Wormhole
Wormhole is a secure, open-source file transfer tool that enables users to send files directly between devices using end-to-end encryption without storing data on intermediate servers. It operates via a web interface or command-line tool, generating unique, time-limited links for sharing files, which are transferred peer-to-peer when possible. Developed by the team behind Magic Wormhole, it emphasizes simplicity, privacy, and cross-platform compatibility for quick, one-off file transfers.
Developers should use Wormhole when they need to securely share files, code snippets, or configuration files between machines without relying on cloud storage or email attachments, especially in scenarios requiring privacy or avoiding file size limits. It is ideal for collaborative debugging, distributing build artifacts, or transferring sensitive data during development workflows, as it minimizes exposure and requires no account setup.
