ZERO Data Inspector: a local tool to inspect structured/semi-structured files (Parquet, CSV, JSON, SQL) on the machine, no cloud upload needed. Ideal for large files, privacy-sensitive data, or restricted environments. Runs as a local web service and can be exposed via a secure tunnel, allowing analysts to remotely inspect data through a browser URL. Focused on direct data inspection — no cloud sync, no auto dashboards, and no generated insights.
