As answered by people managing GitHub Pages 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.

My bookmarks have been public since 1998, and the previous version, bookmarks-v3.0, was a static site generated by Jekyll and published on GitHub Pages: it cost nothing, and for a list of public links it was good enough. The criterion... - Source: dev.to / 30 days ago
The site itself is a statically generated Next.js app, built in CI and deployed to GitHub Pages via actions/deploy-pages. No server to manage, no hosting bill. - Source: dev.to / 7 months ago
Static sites are fast and cheap to host, but your data goes stale the moment you deploy. This post shows how a SvelteKit portfolio site serves live data from five external sources while still deploying as static HTML to GitHub Pages. - Source: dev.to / 7 months ago
