As answered by people managing Responsive Tool and Playwright.
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.
