rift-sdk

High-level SDK for building applications with the riftd P2P protocol.

Part of the riftd project — serverless P2P voice + text chat over UDP.

What's in this crate?

rift-sdk is the easiest way to add P2P voice and text chat to your app:

• Simple API — High-level abstractions over the mesh
• Auto Discovery — mDNS + DHT peer finding
• NAT Traversal — Just works™ (hole punch + TURN fallback)
• E2EE by Default — All messages encrypted end-to-end
• Voice Calls — Opus-encoded voice with QoS adaptation
• Cross-Platform — Desktop, mobile (via FFI), and WASM

Usage

use rift_sdk::{RiftConfig, RiftClient};

#[tokio::main]
async fn main() -> Result<()> {
    let config = RiftConfig::default();
    let client = RiftClient::new(config).await?;

    // Join a channel
    client.join("my-channel").await?;

    // Send a message
    client.send_chat("Hello, world!").await?;

    // Start a voice call
    client.start_call(peer_id).await?;

    // Handle events
    while let Some(event) = client.next_event().await {
        match event {
            RiftEvent::Chat { from, message } => println!("{}: {}", from, message),
            RiftEvent::CallStarted { peer } => println!("Call with {}", peer),
            _ => {}
        }
    }

    Ok(())
}
