Free privacy-first widgets for your website
Embed any of 44calculators, generators and text tools on your site with one paste. Every widget runs entirely in your visitor's browser — no tracking, no cookies, no data collection, no sign-up. Pick a widget, match it to your design, copy the code.
Why embed ToolAnchor widgets?
- Actually private. The widget is a small iframe that computes everything on your visitor's device. No analytics scripts, no cookies, no data sent to us or anyone — safe to use under GDPR without a consent banner.
- One paste, zero maintenance. Two lines of HTML. The widget auto-resizes to its content, follows your visitor's light/dark preference (or the theme you pick), and stays up to date automatically.
- Matches your site. Set the theme, accent color, corner radius and width — or leave it on auto.
- Fast. Widgets are statically served, lazy-loaded and add no JavaScript to your page beyond one tiny loader (or none, with the plain-iframe option).
- Free. The only requirement is the small "Powered by ToolAnchor" attribution link that comes with each widget.
How to add a widget to your site
- Pick a widget above and customize the theme, accent color and size.
- Copy the embed code — the script version auto-resizes; the plain iframe works anywhere HTML is allowed.
- Paste it into your page, post or template where the widget should appear. WordPress (Custom HTML block), Webflow (Embed element), Notion sites, Ghost, Squarespace and plain HTML all work.
FAQ
Do the widgets collect any data from my visitors?
No. The widget iframe contains no analytics, no cookies and no third-party requests. Calculations run in the visitor's browser and results never leave their device — which is why these widgets don't require a GDPR consent banner.
Will it slow my site down?
No — the iframe is lazy-loaded (it only loads when scrolled near) and served from a global CDN. The loader script is under 2 KB.
Can I use widgets on WordPress, Webflow or Notion?
Yes. Use a Custom HTML block (WordPress), an Embed element (Webflow, Framer, Squarespace) or paste the iframe code (Notion-based site builders that allow embeds). If your platform strips scripts, use the plain-iframe code.
Can I remove the attribution link?
The "Powered by ToolAnchor" link is what keeps the widgets free — it must stay visible. It's deliberately small and unobtrusive.
A widget I want isn't in the list — can you add it?
Tell us which one. Most self-contained tools can be made embeddable quickly.
