  • Show HN: Rayfish, Peer-to-peer mesh VPN with no server to trust
    1 project | news.ycombinator.com | 25 Jun 2026
    - A "ray connect" flow links two people directly with no shared room, like a friend request between keys.

    It is a single binary with a daemon and a CLI. `ray up`, then `ray create` or `ray join `, and you have a private network.

    Honest limitations: it is early. The mesh protocol is gated at the transport layer, so we break compatibility between releases when we need to. There has been no third-party security audit yet. Mobile is not there. It runs on Linux and macOS today.

    Code: https://github.com/rayfish/rayfish

    Happy to get into the addressing scheme, the iroh transport, the admission and coordinator model, or anything else.
