Vistumbler

Vistumbler is free, open-source software for scanning and mapping nearby wireless access points with wireless and GPS data. Its stable Windows release finds access points through the Windows Native WiFi API or netsh and can work with COM/NMEA GPS receivers. It supports importing and exporting access point data, saving KML and GPX files, live tracking in Google Earth, and audio alerts. The stable release supports Windows 10 and 11 and requires .NET Framework 4. An experimental MAUI preview is available for Windows and Android 8.0 or later; it adds a live access point list, GPS map, WiFiDB history layers, channel graph, scan transfers, and Android background scanning. The maker says this preview is still in development and may have missing features or bugs. Vistumbler can collect GPS and WiFi location data while running. WiFiDB accepts scan uploads and creates statistics and maps from them. The project describes the software as intended for legitimate network analysis and mapping.

Vistumbler provides wireless scanning, GPS mapping, and export tools, with a stable Windows release and a developing Android preview. Check the platform requirements and preview status before choosing a version.

Vistumbler suits people mapping nearby wireless networks or analyzing local access points. The stable release is for Windows users; the experimental preview also targets Android users.

Overview

Vistumbler is a free, open-source wireless scanner that maps nearby access points using Wi-Fi and GPS data. It suits Windows users doing local Wi-Fi analysis and mapping, especially those who want exports or live Google Earth tracking. Its established Windows release is the clearest choice; the Android option is an experimental preview.

Key features

Vistumbler discovers access points through the Windows Native WiFi API or netsh, then combines scan results with data from COM/NMEA GPS receivers. That makes it useful for recording where networks appear, rather than only viewing nearby network names. The project recommends disconnecting from access points while scanning for best results; if no networks appear, checking the selected adapter is a practical first step.

Access point data can be imported and exported, with KML and GPX export for mapping workflows. Live Google Earth tracking and audio alerts add value when monitoring a scan as it proceeds. Vistumbler also includes asset inventory, but does not provide topology mapping; its scope is local network discovery rather than a broader network inventory or topology platform.

WiFiDB can accept scan uploads from Vistumbler and other scanners, then produce statistics and maps. The MAUI preview adds WiFiDB account support, including registration by QR code or link, as well as a live access point list, GPS map, history layers, channel graph, scan import and export, and Android background scanning.

Pricing

Vistumbler: free. The plan is free and open-source software under GPLv2, unless an individual release specifies otherwise. There is no free trial because the software is free. With no paid tier, there is no lower-priced version that cuts features; the trade-off is that the project provides the software as is, without warranty.

Platforms

The stable release supports Windows 10 and 11 and requires .NET Framework 4. Official releases include an installer, source code, and a portable ZIP. The maker says official downloads do not bundle third-party installers or adware and recommends checking provided checksums and following standard anti-malware practices.

Vistumbler MAUI is an experimental preview for Windows and Android; Android requires version 8.0 or later. The maker says it remains in development, so features may be missing, bugs may occur, and behavior can change between versions. Readers who need a dependable release should favor the stable Windows version over the preview.

Vistumbler can collect GPS and Wi-Fi location data while running. The website says it does not collect device location unless a user explicitly submits it, such as through WiFiDB. The software is intended for legitimate network analysis and Wi-Fi mapping; its terms prohibit unauthorized network access and nonconsensual monitoring.

Who it's for

Vistumbler fits Windows users who want a no-cost way to scan nearby access points and tie results to GPS coordinates, especially when KML or GPX exports, Google Earth tracking, or audio alerts matter. Its local scope and lack of topology mapping make it a narrower choice for network discovery than tools aimed at managing broader infrastructure. The experimental Android preview may interest users who want mobile scanning, but its in-development status makes it a less settled option.

Pros and cons

• Pro: Free, open-source software with installer, source, and portable ZIP downloads gives users several ways to obtain or inspect the stable Windows release.
• Pro: GPS receiver support, KML and GPX export, and live Google Earth tracking support location-based Wi-Fi mapping.
• Pro: WiFiDB can turn submitted scans into statistics and maps, extending the value of collected scan data.
• Con: Stable support is centered on Windows 10 and 11 and requires .NET Framework 4, limiting its fit for users seeking a mature Android release.
• Con: The MAUI preview may have missing features and bugs, so it is a poor fit when consistency is essential.
• Con: Vistumbler maps local access points but does not map network topology, which limits its use for broader infrastructure views.

Alternatives

Choose Fing Security if you want network and ISP reporting, troubleshooting tools, or internet speed tests across a wider range of platforms; its free plan allows up to 3 scans per day. ManageEngine OpUtils is a better fit for basic IP and network scanning across a defined small network: its free plan covers 1 Class C subnet and 1 switch.

Domotz offers a per-device option at $1.50 a month, billed per managed device in bundles of 10. Lansweeper has a 14-day full trial that continues free for up to 100 assets with unlimited user seats. Netdisco is a free, self-hosted open-source alternative. OCS Inventory is an open-source community project. LOGINventory offers a forever-free plan for up to 20 devices. NetworkTonic is another free option for Windows, macOS, and Linux.

Verdict

Vistumbler is a strong fit for Windows users who want free, open-source local Wi-Fi scanning with GPS mapping and useful export options. Its best reason to choose it is the combination of location-aware scans, KML and GPX export, and live Google Earth tracking at no cost. Look elsewhere if you need topology mapping or a mature mobile release; the Android version is still experimental.
