Work & products
Our own products are our longest-running case studies. Since 2013 they have grown into suites of free tools for developers, network admins and marketers — designed, built, ranked and maintained by our team.
DNS lookup and propagation tools
Our flagship: a free suite of DNS, IP, email and network tools that checks records against name servers around the world. Designed, built and ranked by our team.
IP address geolocation
It started with one question — where is this IP address? — and grew into tools for IP, DNS, email, SEO and security, with results cross-checked across several geo-IP providers.
Global DNS propagation checks
A focused, fast propagation checker that queries DNS servers in multiple locations and shows the answers side by side.
QR code scanning and generation
Scan QR codes and barcodes from an image or your camera, right in the browser — with generators for QR, Wi-Fi and vCard codes, in many languages.
Case studies from client projects are on the way. Ask us for examples and references relevant to your project.
