It brings together 35 in-depth tools, from IPv4/IPv6 subnetting and IP, DNS and WHOIS infrastructure lookups to 2FA code generation, number-base conversion and bulk text processing. Everything runs instantly in the browser, freeing you from software installation and from any sign-up process.

Subnets follow the RFCs. Hardware names come from the IEEE registry. 2FA codes follow RFC 6238, colour follows the CIE and WCAG formulas. Every calculation is checked against reference results by an automated test before it ships.
Pages are light. There is no pile of extra files to wait for, so old devices and slow connections still work. Turn JavaScript off and most tools keep running. Every control is big enough to hit with a thumb.
IP location, DNS, WHOIS and map tiles all have to ask an outside service. Each one has at least two providers. If the first goes quiet the request moves to the next. You never see an error page.
What you type into the calculators is never stored. QR images are decoded in your browser where the device supports it. Secrets and passwords kept in your vault are encrypted with AES-256-GCM. Nothing is sold, and nothing goes to an advertiser.
Eight core tools sit in the sidebar. The rest live in the library, where a filter narrows the list as you type and matches on what a tool does, not only on its name.
Each tool takes several ways of writing the same thing. Cisco-style MACs, wildcard masks, 0x-prefixed numbers, dates written in words. Paste and go.
Results come as clearly labelled tables. One click copies any of them. Create a free account if you want to keep them.
No sign-up needed. A free account only matters if you want to keep secrets, passwords and API keys.
