(Optional GUI) If you are managing dozens of machines, reading raw JSON files manually can be painful. My team uses a pre-compiled GUI viewer we built that aggregates these JSONs into static, filterable HTML dashboards.
If you want to save time building your own parser, you can grab the standalone GUI tool here: 👉 [Get Zero Agent Viewer on Gumroad]
