TECHNICAL TOOLS

Help yourself.

Twelve free technical tools, no sign-up and no email required. Calculated in your browser, instant results, shareable by URL. Nine are live; the last three — driven by standards tables still to be entered — are coming in later sessions.

The essentials

  • No sign-up, no email — the calculation runs in your browser
  • Every tool's state is encoded in the URL: a calculation shares like a link
  • Every page stays readable and complete with JavaScript off — the tables live in the HTML
  • Every tool states its limits: what it does not let you conclude

Frequently asked questions

Are these tools really free?
Yes, no sign-up or email required. We use them ourselves every day to price our own orders, so there is no reason to keep them to ourselves.
Are the calculations run on your servers?
No. Every calculation runs in your browser in JavaScript, with no network call — your data never leaves your device, and the tools keep working offline once the page has loaded.
Can I share a calculation result?
Yes: a calculation's parameters are encoded in the page URL. Copying the link is enough to hand a colleague the exact same configuration.
What if my case falls outside what these tools cover?
Every tool has a "Limits" section stating what it does not let you conclude. For a case outside that scope, send us your requirement directly through a quote request.
