Show HN: NoonFlow – a macOS workspace I built for Claude Code and Codex • Hacker News Board

I tried a lot of existing options for working with Claude Code and Codex, but none really fit my habits — always felt like something was missing. So I built NoonFlow around my own workflow. I've been using it daily for over a month before deciding to share it.

Not just two CLIs in one window: - a chat-style UI instead of terminal-first - both runtimes inside the same workspace - skills, session history, and session memory are first-class with real management

macOS 13+ (Apple Silicon) only for this build, signed and notarized.

Happy to hear what's missing if you also live in these CLIs.

I think the scrollbars need to be gray or black.

Good call, I'll look into that. Thanks for the feedback.

I haven't finished cleaning it up for release, but I plan to open-source it soon
