TapMap

About

TapMap is an open source app that shows your computer's network connections on a map, so you can see what is connecting and where. It keeps the last 30 days of activity, which helps you tell apart the connections you see regularly from those that appear only briefly. TapMap is an awareness tool, not a firewall or security suite. It runs locally, has no telemetry, and does not transmit connection data unless you configure MQTT notifications. By default it queries a public IP lookup service to estimate your location, but you can turn this off by entering your location manually.

TapMap can notify you when it notices a Significant Connection, such as a new app, country, network provider, or remote port, or when an app fails verification. Native desktop notifications can be turned on or off, and you can review the latest 500 events in a separate history. For setups where desktop notifications are unavailable, such as Docker, you can publish Significant Connections to an MQTT broker you configure. TapMap keeps running after you close the browser and can be opened or quit from the system tray on Windows and Linux or the menu bar on macOS.

TapMap is available as a Windows installer, a macOS disk image, or a Debian package, and no Python setup is required. The macOS app is signed and notarized. Application information shows which app is connecting, who created it, and whether your operating system verifies it, with technical details available when you want them. No user account is required.
