What you can try

• Dwell lab

  Simulate how page structure changes how long a visitor stays. The illustrative model estimates dwell time in seconds, bounce risk and scroll depth from lead length, a table of contents, related articles, media, ads and connection speed. It is a model, not a measurement.

  Controls: reading time, short or long lead, table of contents, related articles, no media / photograph / illustration, interstitial ads and connection speed. Try the challenge: hold a visitor for two minutes on a four-minute article over a slow connection.

• Speed lab

  Simulate how technical choices change page speed. The illustrative model estimates a request waterfall, Largest Contentful Paint, Interaction to Next Paint, Cumulative Layout Shift, a 0 to 100 score and page weight. It is a model, not a measurement.

  Controls: hero image format (JPEG, WebP, AVIF), width and quality, lazy-loading, image dimensions, JavaScript size, font strategy, CDN caching, client or server rendering, connection speed and device CPU. Try the challenge: reach a score above 90 under 300 KB.

• Search and social preview

  Type a page title, meta description and URL slug and see a Google-style result preview on desktop and mobile, with truncation measured in pixels, plus an Open Graph and Twitter card preview.

  Controls: title, description, slug, desktop or mobile toggle, example presets, a randomise button and a copy-HTML-tags button.

• Contrast checker

  Pick a text and background colour to see the WCAG 2.2 contrast ratio and pass or fail results for AA and AAA normal text, large text and user interface components, with an automatic fix and colour-vision-deficiency simulation.

  Controls: colour pickers and hex inputs, swap, brand presets, auto-fix to AA or AAA and protanopia, deuteranopia or tritanopia preview.

• Project estimator

  Choose a project type, number of pages and extras to get an indicative package (Starter, Growth or Scale) and a transparent timeline in weeks. It is an indicative estimate, not a quote.

  Controls: project type, page count slider and extras such as migration, multilingual, advanced SEO, performance budget, review workflow and accessibility audit. Copy a summary or continue to the contact page.

• Page composer

  Arrange a page from hero, feature grid, testimonials, pricing, FAQ, case studies, call to action and table sections in a miniature wireframe, and see a live page health check with suggestions.

  Controls: add sections, drag to reorder or use move up, move down and remove buttons, reset and share the layout as a link.
