What It Does

Details

Onionlink is a small C++20 Tor v3 onion-service client that communicates directly with Tor relays, builds necessary circuits for v3 access, and supports raw data exchange or HTTP requests with the service. It omits extensive security features present in standard Tor clients to focus on interoperability.

Why It Matters

Why this one made the cut

Onionlink provides a tool for developers and researchers interested in interacting with onion services without relying on full-fledged Tor client implementations. It aids understanding of the underlying protocol mechanisms involved in accessing onion services.

Differentiator

What makes it different

While many Tor clients are complete software solutions, Onionlink focuses narrowly on connecting to v3 onion services using minimal libraries, making it a valuable tool for educational and experimental purposes.
