Questions & Answers

As answered by people managing kdiff3 and Sleek Compare.

What makes your product unique?

Sleek Compare's answer:

Sleek Compare is built with a strict performance budget. The entire plugin - JavaScript and CSS combined - ships under 10KB with zero external dependencies. No jQuery, no FontAwesome, no third-party libraries. Most competing before/after slider plugins load 50-200KB+ of assets. Sleek Compare also prioritizes accessibility from the ground up with full keyboard navigation, ARIA attributes, and WCAG 2.1 AA compliance, which most competitors skip entirely.

Why should a person choose your product over its competitors?

Sleek Compare's answer:

If page speed and Core Web Vitals matter to you, Sleek Compare is the clear choice. It scores perfect Lighthouse performance scores while competitors like BEAF and TwentyTwenty rely on jQuery and heavier asset chains. It also offers native integration with both Gutenberg and Elementor out of the box, plus a universal shortcode fallback. The Pro license is a one-time $29 payment with lifetime updates - no annual subscriptions.

How would you describe the primary audience of your product?

Sleek Compare's answer:

WordPress site owners and developers who need to show visual before/after comparisons - photographers, home renovation contractors, dental and medical practices, fitness coaches, web designers showcasing redesigns, and e-commerce sites showing product transformations. Also developers and agencies building client sites who need a lightweight, reliable slider that won't tank performance scores.

What's the story behind your product?

Sleek Compare's answer:

I needed a before/after slider for a client project and every option I found was bloated, inaccessible, or both. The popular plugins were loading jQuery and icon fonts just to drag a line across two images. I built Sleek Compare to prove you could do it in under 10KB with full accessibility and page builder support. It started as a personal tool and turned into a product when other developers kept asking for it.

Who are some of the biggest customers of your product?

Sleek Compare's answer:

  • WordPress developers building client sites for small businesses
  • Photography studios showcasing editing work
  • Home renovation and construction companies showing project transformations
  • Dental and medical practices displaying treatment results
  • Fitness coaches and personal trainers showing client progress
  • Web design agencies demonstrating site redesigns
  • E-commerce stores comparing product versions or upgrades

Which are the primary technologies used for building your product?

Sleek Compare's answer:

Vanilla JavaScript (ES6+), CSS custom properties for theming, IntersectionObserver API for lazy loading, WordPress PHP for the plugin backend, React for the Gutenberg block editor integration, and the Elementor Widget API for the page builder widget. No frameworks, no libraries, no build-time CSS-in-JS. Just clean, minimal code.
