croc is a Go CLI tool that lets any two computers securely transfer files and folders peer-to-peer with end-to-end encryption via PAKE, falling back to a relay when needed. It supports resumable transfers, multiple files, IPv6-first networking, proxy/Tor usage, and a browser client compatible with the CLI.

Use cases

• send a file to a friend without setting up a server
• transfer files between Windows and Mac securely
• resume an interrupted large file transfer
• send files without port forwarding
• transfer files over Tor for privacy
• receive files in the browser from a CLI user

When to choose

• you need simple, encrypted, cross-platform file transfer between two machines
• you cannot configure port forwarding or run a server
• you want resumable transfers over flaky connections

When to avoid

• you need to share files with many recipients or host public downloads
• you need a GUI-first workflow or managed cloud storage
• you need transfer within an air-gapped network without any relay
