About

Ever seen a browser prompt saying a website wants to “connect to a device on your local network” — and wondered why?

LNAlyzer helps you understand those requests. Some websites use a new browser capability called Local Network Access (LNA), which allows them to try connecting to devices or services inside your private network (like your router, smart home devices, or local servers).

LNAlyzer provides a simple pane where you can view the requests directly, without having to analyze DevTools. It shows:
1. The full URL of each request
2. Which website made the request

Whether you’re curious or security-minded, LNAlyzer gives you visibility into what’s happening behind the scenes.

Key features:
1. Detect and log Local Network Access (LNA) requests
2. View full request URLs in a clear, easy-to-read pane
3. Understand which sites are scanning or probing your private network
4. Lightweight, private, and open-source — no data leaves your browser
