Tools load from EvvyTools.com. When we publish a new calculator or fix a bug, your site gets the update instantly — no plugin updates required.
Every embedded tool adapts to the container width and auto-resizes its height. No overflow, no scrollbars — it just fits.
The plugin is under 7 KB. Tools load inside iframes with loading="lazy", so they don't affect your page speed until scrolled into view.
Install, activate, embed. There's no signup, no API key, no paywall. All free tools work out of the box.
Tools detect your visitor's light/dark preference automatically, or you can force a theme per shortcode to match your site design.
Finance calculators, health tools, dev utilities, cooking converters, and more. New tools appear in your plugin settings automatically.
Interactive tools increase time-on-page, reduce bounce rate, and give your visitors a reason to come back.
Embed compound interest, debt payoff, or retirement calculators alongside your financial advice articles.
Add BMI, calorie, or macro calculators to nutrition guides and fitness content.
Include JSON formatters, UUID generators, or encoding tools in your technical tutorials.
Help visitors calculate mortgage payments, affordability, or closing costs right on your listings.
Free forever. No account needed. Install in under a minute.
