Overview

What it is

FireWally is a privacy-first network tool designed to give you full control over your Mac’s online activity. See which apps are actively connecting to the internet in real time, block unwanted connections, and explore detailed traffic history by the hour or for the entire day. Apple Intelligence–powered insights help you understand why apps connect and whether they’re safe, making FireWally a smart, intuitive way to protect your privacy and take control of your network.

Intent

I need it when

Monitor and control which applications access the internet on their Mac

FireWally displays all active apps and services connecting to the internet in real-time, allowing users to see exactly which apps go online and when. Users can block unwanted app connections with a single click and manage background syncing to maintain control over network activity.

Understand why applications are connecting to the internet and what they are doing

FireWally uses Apple Intelligence to provide intelligent summaries explaining exactly what each app is and why it's connecting to the network. This helps users identify unusual patterns and unexpected background activity.

Reduce data usage and stay within mobile hotspot or limited data plan limits

FireWally provides a visual breakdown of app-level and system-wide network traffic (inbound, outbound, and total volume), helping users identify high-bandwidth apps and unnecessary data usage. Users can pause connections and disable background syncing to avoid surprise charges.

Replace paid firewall solutions with a lightweight, resource-efficient alternative

FireWally is free and uses minimal CPU and RAM compared to alternatives like Little Snitch, making it efficient for users running multiple applications while maintaining full firewall functionality and app-level network control.

Track network activity patterns over different time periods to identify anomalies

FireWally allows users to explore network activity across multiple time ranges: real-time internet traffic, the past hour, and the current day. This enables identification of unusual spikes or background activity patterns.

Drop

Not a fit when

  • User requires firewall for Windows or Linux systems; FireWally is Mac-only
  • User needs to block apps before they launch; current version only blocks after detection
  • User requires monitoring of iOS simulator or system processes that don't appear in the app interface
  • User needs advanced firewall rules or port-level filtering; FireWally focuses on app-level control
  • User operates on macOS versions older than 13.0; app requires macOS 13.0 or later
