What I learned building Hyerix — a Tauri v2 + async-nats desktop app for NATS infrastructure. Covers IPC backpressure, cross-platform signing pain, and the local-first AI architecture.

I built Hyerix — a desktop app for managing NATS infrastructure (JetStream streams, KV buckets, Object Store, consumers, cluster topology). It's Tauri v2 + Rust + React/TypeScript, talking to clusters via async-nats. There's also a natural-language query layer over live cluster state.

Why a desktop app

The NATS CLI is excellent for one-shot scripting.…
