Free Embeddable Dev Tool Widgets — No Tracking, No Server

Most "free" online tools phone home. Yours don't have to.

We just shipped embeddable versions of our most-used developer tools. You drop an iframe into any blog post, docs page, or internal wiki, and your readers get a working tool — running entirely client-side, with zero tracking, zero cookies, zero data collection.

<iframe src="https://embed.formatho.workers.dev/base64"
        width="420" height="340" style="border:0;border-radius:8px"
        title="Base64 Encoder by Formatho"></iframe>
Enter fullscreen mode Exit fullscreen mode

What's available

  • Base64 encoder/decoder — embed.formatho.workers.dev/base64
  • UUID v4 generator (batch up to 10) — /uuid
  • SHA-256 hasher — /hash
  • Unix timestamp converter (live clock) — /timestamp

Why we built them

Formatho is 100+ privacy-first developer tools at formatho.com — everything runs 100% in your browser. We kept getting the same question: "can I use this inside my docs?" Now you can.

The privacy bit, concretely

  • No analytics on embeds. None.
  • No cookies, no localStorage on the widget pages.
  • Processing happens in the iframe, in your reader's browser.
  • Workers serve static HTML; they don't log inputs.

Use cases we've seen

  • Encoding/decoding snippets inside API tutorials
  • UUID generation in onboarding docs
  • Timestamp conversion in runbooks

Grab a widget at formatho.com — and if you want the full in-browser versions (100+ tools, works offline), they're free too.

Feedback welcome — what widget should we embed-ify next?
