Free tools, no sign-up.

Most of the free website tools we learned on have moved behind paywalls, so we build our own and share them. They run in your browser: nothing you type is sent to us.

Schema markup generator

Build valid structured data for FAQ pages, articles and local businesses. Copy it straight into your page.

  "@context": "https://schema.org",
  "@type": "FAQPage",
  "mainEntity": [{
    "@type": "Question",
    "name": "Do you ship overseas?",

Why they're free

Free tools helped build most of what you see on this site. When they started disappearing behind subscriptions, it made sense to make a few and give them away.

They're small on purpose: each does one job correctly and loads fast. If you use them for client work and want a hand with the bigger picture, get in touch.
