Connect any two devices on the planet

Iroh gives you an API for dialing by public key. You say “connect to that phone”, iroh will find & maintain the fastest connection for you, regardless of where it is.

“In stark contrast to other p2p & dweb technologies we've played with - which are exciting due to their implications for the future - Iroh brought instant gains in our present."

Smaller is better

In the upcoming v0.26.0 release, We're doubling down on iroh's networking stack as “what iroh is”, describing everything else as a custom protocol
