Responsively 6 features
Responsive Tool 5 features
  • Multi-device Preview

  • Open Source
    Being an open-source project, it allows for community contributions, transparency, and no licensing fees.
  • Sync Scrolling and Clicks
    Enables synchronized scrolling and clicking across all previews, making it easier to test interactions and layouts uniformly.

Possible disadvantages

  • Limited Browser Support
    May not offer the same level of browser compatibility testing as dedicated tools like BrowserStack or Sauce Labs.
  • Steep Learning Curve
    New users might require some time to get accustomed to the interface and functionalities compared to more straightforward testing tools.
  • Resource Intensive
    Running multiple device previews simultaneously can consume considerable system resources, which might slow down other tasks.
  • No Cloud Integration
    Lacks integration with cloud services for remote testing, unlike some paid alternatives.
  • Dependence on Electron
    As an Electron-based app, it might have a larger memory footprint compared to native applications.
  • Device Presets
    20+ real phone, tablet, and desktop viewport sizes
  • Custom Width
    Enter any exact pixel width to test, not just presets
  • Breakpoint Testing
    One-click jumps to common CSS breakpoints at -1px/exact/+1px, so you can check the edge, not just the round number
  • Live Preview
    Free, no signup or install required
  • Shareable Setup Links
    Copy a link that reproduces your exact comparison — same URL, same devices, same custom widths — for anyone who opens it

Questions & Answers

As answered by people managing Responsively and Responsive Tool.

Which are the primary technologies used for building your product?

Responsive Tool's answer:

Next.js, React, TypeScript, Tailwind CSS, deployed on Cloudflare Workers.

What makes your product unique?

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.

Why should a person choose your product over its competitors?

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.

How would you describe the primary audience of your product?

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.
