HiyokoBar

HiyokoBar is an AI-assisted macOS menu bar monitoring tool that pushes script and service status directly to engineers, eliminating the need to manually check terminals or dashboards. Unlike pull-type monitoring tools that require you to go look for information, HiyokoBar runs any shell script, Python file, or JavaScript file on a configurable schedule and surfaces results as glass-style cards directly under your macOS menu bar.

When a script fails, Gemini AI automatically analyzes the error and presents an AI Insight panel inline — no manual copy-pasting of logs into a chatbot required. The entire tool is configured through a full GUI, so there is no JSON editing or config file management involved. Cards can be reordered via drag and drop, and a real-time countdown shows exactly when the next script execution will run.

HiyokoBar includes macOS Keychain integration for secure API key storage, a Login Item option so it auto-starts at login, and support for both English and Japanese interfaces. It is a macOS-only desktop application sold as a $39 one-time purchase with a lifetime license, free updates within the v2.x line, and a 7-day money-back guarantee. Purchases are currently processed through LemonSqueezy.

The tool is designed for engineers and developers who want a passive, push-style HUD to keep tabs on scheduled tasks, service health, and script outputs — all without leaving their workflow to open a terminal or reload a monitoring dashboard.
