See who any website talks to.
NetLens watches every network request a page makes in the background and breaks it down by category — trackers, ads, APIs, CDNs, fonts — with a privacy grade. No DevTools, no setup.
🔒 Runs 100% in your browser — nothing is uploaded.What it shows
Turn the raw network firehose into a clear, categorized picture.
Category breakdown
Analytics, ads, social, tag managers, CDNs, fonts, monitoring, payment, support, video — matched to known vendors.
Privacy grade
An A–F grade from third-party and tracker counts, so you know at a glance how chatty a site is.
First vs third party
Every external domain a site contacts, grouped by registrable domain and company.
Sizes & counts
Requests and transfer bytes per category and per domain — see what's bloating the page.
Export & share
Download the report as JSON, or open the in-depth report page (a shareable link).
Local-only
All analysis runs in your browser. The vendor dataset ships in the extension — no phone-home.
