Use with authorization only. Scan networks and hosts you own or have explicit written permission to assess. Unauthorized scanning can violate acceptable-use policies and, in some jurisdictions, the law.

Overview

Fing is a network discovery and monitoring application developed by Fing. It is designed to help users identify the devices connected to a network, monitor for changes, and keep track of basic network health indicators such as internet speed and outages. The tool is used by both home users wanting visibility into their own network and IT professionals performing lightweight network audits.

Fing is offered as freeware for its core application, with additional paid products available from the same vendor, including Fing Desktop as a premium tier, the Fingbox hardware device for continuous monitoring, and a developer toolkit/API for integrating Fing’s network data into other software. The free application provides the baseline discovery and monitoring functionality described below.

Key capabilities

Fing focuses on visibility into what is connected to a network and how that network is behaving:

Discovers devices connected to a local network and attempts to identify device type, vendor, and other identifying details.
Scans discovered devices for open ports, which can help flag services that may be unexpectedly exposed.
Monitors the network for changes over time, such as new devices joining or existing devices going offline.
Generates alerts for potential intrusions or the appearance of unrecognized new devices on the network.
Provides internet speed testing and checks for service outages affecting connectivity.
Presents a consolidated view of network state that can be reviewed periodically or in response to an alert.

Typical use cases

Home users commonly use Fing to see which devices are connected to their router, spot unfamiliar devices, and get a general sense of network performance. Small-business and IT users use it for lightweight, ad hoc audits of a network segment, checking for unexpected open ports or newly connected hardware without deploying a full network management suite. The alerting features are also used to keep informal watch over a home or small office network for unauthorized access attempts.

Scanning and monitoring should be performed only on networks you own or are explicitly authorized to assess; using Fing to probe networks without permission is not an appropriate use of the tool.

Licensing and pricing

The core Fing application is freeware. The vendor also sells premium products, including Fing Desktop, the Fingbox hardware appliance, and a developer toolkit/API, which carry their own pricing. This catalog does not list specific prices, as they are subject to change; consult Fing’s official website for current pricing on any paid product or service tier.

Platform support

Fing is available as a mobile application for iOS and Android, and as a desktop application for Windows and macOS.

Getting started

Fing is downloaded from the vendor’s official website or from the respective app stores for iOS and Android. This catalog entry does not host installers; always obtain the application from https://www.fing.com or an official app store listing to ensure you are installing genuine software. Once installed, the app typically scans the local network automatically to build an initial device list, after which alerts and monitoring can be configured according to the user’s preferences.
