LocalSend3DS is an unofficial LocalSend-compatible client for the Nintendo 3DS family.

It supports bidirectional discovery and one-file transfers with official LocalSend clients. Incoming transfers use HTTP, while outgoing transfers support HTTP and fingerprint-pinned HTTPS with mutual TLS.

Real-hardware interoperability has been verified with macOS, Linux, and Android.

PIN-protected recipients, multiple files, folders, text, clipboard transfers, and incoming HTTPS are not currently supported.
