🎉 Introducing fastn-context: Hierarchical Debugging for fastn Applications

[amitu]

We're excited to announce fastn-context - providing immediate operational visibility into your fastn applications with zero boilerplate!

🔍 Live Production Debugging

See exactly what's running and what's stuck:

$ fastn status
✅ global (2h 15m, active)
  ✅ remote-access-listener (1h 45m, active)
    ✅ alice@bv478gen (23m, active)
      ❌ stdout-handler (12m, cancelled) ⚠️ STUCK

Context trees build automatically as your application runs. Get immediate answers to "Why is my service stuck?" with precise operation identification and timing.

🚀 Zero Boilerplate Setup

#[fastn_context::main]
async fn main() -> Result<()> {
    let ctx = fastn_context::global();
    
    ctx.spawn_child("p2p-server", |server_ctx| async move {
        // Automatically tracked with timing and cancellation
        // Appears in live status tree immediately
    });
}

Production ready with hierarchical cancellation, distributed tracing, and comprehensive testing. Perfect for debugging P2P services, async operations, and complex distributed systems.
