Score: 7.0/10 (Innovation: 7, Technical: 7, Documentation: 8, Utility: 6)

Tubo is a zero-install, end-to-end encrypted file transfer tool designed for locked-down servers where root access or binary installation is impossible. It uniquely leverages only curl and openssl via a POSIX shell fallback, making it usable on noexec file systems, while the relay server acts as a blind pipe that never sees the encryption key.

Target audience: devops, backend devs, system administrators, security engineers
