OpusBar is a free, open-source macOS menu bar app for Claude Code and Codex. A pixel cat shows your most urgent session, and a badge counts the ones waiting on you. It tracks 5-hour and weekly limits and what your tokens would cost. Nothing leaves your Mac.
Most AI coding agents forget your codebase the moment the prompt ends. Athena doesn't. It builds a real knowledge graph of your project symbols, call paths, dependencies so it edits with the same context an Architect would have. Open source, terminal-native, provider-agnostic.
