- Customizable alerts: Set thresholds for bandwidth usage and receive on‑screen warnings when limits are approached.
- Exportable logs: Save session data in CSV format for later analysis or reporting.

Installation & Usage Instructions
Getting started with Flame is intentionally uncomplicated. First, download the DMG file from the official site; the file is signed and free of adware, providing a secure entry point for Mac users. Open the DMG and drag the Flame icon into your Applications folder—standard macOS installation practice. When you launch the app for the first time, macOS may warn you about an unidentified developer; simply click “Open” in the security dialog, as Flame is verified by its developer’s certificate. Once running, the main dashboard presents two primary panels: a live traffic graph and a protocol list. To begin monitoring, select the network interface you wish to observe (Wi‑Fi, Ethernet, or Thunderbolt) from the dropdown at the top. Flame immediately starts capturing packets, displaying total bandwidth, packet count, and a breakdown by protocol. For deeper analysis, click any protocol entry to reveal a detailed flow view, showing source and destination IPs, ports, and timestamps. If you need to set an alert, navigate to the Settings tab, choose “Alerts,” and define a bandwidth threshold (e.g., 100 Mbps). Flame will flash a warning and optionally play a sound when traffic exceeds this limit. To preserve a session, click the “Export” button and choose CSV; the file can be opened in Excel or any spreadsheet program for further inspection. Finally, when you’re done, simply quit the app; it will not leave background processes running, preserving your Mac’s performance.
