About NetScopeKit

NetScopeKit is a free collection of browser-based network and web development tools built for developers, system administrators, and IT professionals. Every tool is designed to work directly in your browser — no accounts, no downloads, no server-side processing of your data.

The project was born from a simple idea: common network diagnostics and utilities should be free, fast, and private. Instead of uploading your data to someone else's server, NetScopeKit processes everything locally or sends queries directly from your browser to public APIs like Cloudflare DNS, ipify, and RDAP registries.

NetScopeKit is operated by Tom Silas Helmke from Germany. For legal and contact information, see the Impressum.

Privacy-First Approach

Local processing: Tools like the QR Code Generator, Subnet Calculator, and Keyboard Tester run entirely in your browser. No data leaves your device.

Direct API access: Tools that need external data (DNS Lookup, RDAP, What Is My IP) send requests directly from your browser to public APIs. NetScopeKit does not proxy, intercept, or log these requests.

No tracking: There are no analytics scripts active on this site. Google AdSense is only loaded after explicit marketing consent via the cookie banner.
