As answered by people managing Float UI and Responsive Tool.
Responsive Tool's answer:
Next.js, React, TypeScript, Tailwind CSS, deployed on Cloudflare Workers.
Responsive Tool's answer:
It renders live, interactive iframes side by side — not static screenshots — across real device viewport sizes, with one-click jumps to common CSS breakpoint boundaries (e.g. 767/768/769px) so you can test right at the edge, not just round numbers. You can also copy a link that reproduces your exact comparison (same URL, same devices, same custom widths) for anyone else to open.
Responsive Tool's answer:
Most cross-browser/device testing platforms (BrowserStack, LambdaTest, etc.) are built for QA teams running automated test suites across real device clouds — paid, feature-heavy, and overkill for a quick visual check. Responsive Tool is free, requires no signup, and is built specifically for one thing: seeing how a page looks across device sizes at a glance.
Responsive Tool's answer:
Indie developers, freelancers, and small teams who need a fast, free way to sanity-check a responsive layout without setting up a device lab or a paid testing platform.
