Product overview
What is WiFi Lens?
WiFi Lens is a native macOS app that turns nearby wireless activity into a readable map. Scan 2.4, 5, and 6 GHz networks, compare signal strength, spot crowded channels, and test coverage as you move through a space. The app processes scans on your Mac. When you enable its local MCP server, compatible AI tools can inspect the same data without uploading it.

See live spectrum activity across all major Wi‑Fi bands. Quickly spot where things are busiest and which channels are jammed.
AI Workflows
Chat with your Wi‑Fi
WiFi Lens can connect to MCP, letting AI tools like Claude Desktop read Wi‑Fi data directly — all processed on your machine, nothing uploaded to the cloud. Ask "which channel is least crowded?" or "what stands out in nearby networks?"

View pageFAQFrequently asked questions
Answers to common questions about WiFi Lens — pricing, macOS requirements, data privacy, Pro vs OSS differences, and 6 GHz support.
View pageIs WiFi Lens free?
Absolutely. WiFi Lens OSS is open source and completely free — you can download and use it from GitHub with no restrictions. The Pro version is a one-time purchase through the App Store that adds the menu bar status monitor and the Timeline event history. The core Wi‑Fi analysis capabilities are identical between both versions.
What's the difference between Pro and OSS?
The OSS version covers the core analysis features: spectrum scanning, network table, channel scoring, roaming tests, connection diagnostics, network self-check, and MCP AI integration. The Pro version adds the menu bar status monitor and the Timeline event history. For live analysis of your current network, the OSS version is enough.
Is my data uploaded to the cloud?
Absolutely not. WiFi Lens has no backend servers whatsoever. All data is processed locally on your Mac. Even the MCP AI integration only communicates through your machine's local interface — nothing is sent to any remote server. To be crystal clear: we don't collect anything.
What macOS version do I need?
WiFi Lens requires macOS 14 (Sonoma) or later. It supports both Apple Silicon and Intel Macs. A quick note: 6 GHz band scanning requires your Mac hardware to support Wi‑Fi 6E or Wi‑Fi 7 (available on newer Apple Silicon models). Older Intel Macs or non-6E models can still use all 2.4 GHz and 5 GHz features without limitation.
Why don't some 6 GHz networks show a 6 GHz label?
This is a macOS system-level limitation. The wireless scanning APIs macOS provides to apps don't always explicitly flag a network as belonging to the 6 GHz band. For Wi‑Fi 6E networks, the system typically encodes band information through the channel number or center frequency rather than returning a "6 GHz" label directly. As a result, some 6 GHz networks may appear as 5 GHz or without a specific band label in scan results. This is system behavior, not a bug — it doesn't mean the device isn't using a 6 GHz network.
