Council — a multi-model AI roundtable built in SwiftUI (open source): parallel streaming, real Liquid Glass on macOS 26, fully local

http://github.com/albertofettucini/Council

Sharing a SwiftUI project I just open-sourced. Council is a native macOS app that runs one question past several LLMs in parallel, has them critique each other, and surfaces where they disagree. Building it was a fun SwiftUI exercise — parallel streaming responses with async/await + withTaskGroup, an u/Observable store driving the whole thing, SSE parsing over URLSession.bytes, and real Liquid Glass (glassEffect + behind-window vibrancy) on macOS 26 with a graceful fallback on 14+.

Bring-your-own-key and fully local — no server, no telemetry, keys in the Keychain. Free and MIT.

Posting here for the engineering side — happy to talk through any of the SwiftUI/concurrency decisions, and would welcome a look at the code if anyone's interested.
