I built an agent observability & orchestration toolkit over the holidays https://github.com/run-vibes/vibes. It uses Iggy as the message streaming layer and currently supports PTY streaming for Claude Code to the browser, Cloudflare tunnel, automatic Claude Code hook instrumentation into Iggy and I'm using that to build a cross harness continual learning system that I'm hoping will act as error correction for the model environment. It's using Iggy server v0.6 (io_uring on Linux) and compiles to native platform binaries for Linux & Mac (Windows support is on the list...)
