Why site owners love it
Always current
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.
Responsive by default
Every embedded tool adapts to the container width and auto-resizes its height. No overflow, no scrollbars. It just fits.
Lightweight & fast
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.
No account required
Install, activate, embed. There's no signup, no API key, no paywall. All free tools work out of the box.
Theme-aware
Tools detect your visitor's light/dark preference automatically, or you can force a theme per shortcode to match your site design.
191+ tools & growing
Finance calculators, health tools, dev utilities, cooking converters, and more. New tools appear in your plugin settings automatically.
Built for content creators
Interactive tools increase time-on-page, reduce bounce rate, and give your visitors a reason to come back.
Finance bloggers
Embed compound interest, debt payoff, or retirement calculators alongside your financial advice articles.
Health & wellness
Add BMI, calorie, or macro calculators to nutrition guides and fitness content.
Developer blogs
Include JSON formatters, UUID generators, or encoding tools in your technical tutorials.
Real estate sites
Help visitors calculate mortgage payments, affordability, or closing costs right on your listings.
