Axure RP

Axure RP is a popular tool used by UX designers to create wireframes, prototypes, and specifications for websites and applications. It’s often used in the planning phase of a project to create mockups and to define user interactions. The Axure RP Chrome extension enhances this experience by allowing you to preview your prototypes directly in the browser, as if they were the real website or application. It interprets the Axure RP file format and displays it as an interactive webpage.

Here are some tasks that the Axure RP Chrome extension can assist with:

  1. Prototype Testing: With the extension, you can test your prototypes interactively in the browser, simulating the end-user experience. This can be invaluable in identifying design flaws or usability issues.
  2. Collaborative Review: You can share your prototypes with colleagues or stakeholders to gather their feedback. Because they’re seeing it in the browser, it’s closer to the final product experience.
  3. User Testing: The extension can be used during user testing sessions. It will allow users to interact with your design as though it were a fully functional website or application. This gives more realistic feedback and insights.
  4. Demonstration of UX/UI Designs: The extension provides a realistic environment for demonstrating your designs to clients or stakeholders. It’s much more engaging to show an interactive prototype rather than static images.
  5. Iteration: The extension can speed up the process of iterating on your designs. You can make changes in Axure RP, and then quickly preview those changes in the browser.
  6. Dynamic Content: Axure RP and the corresponding extension support the creation and preview of dynamic content, such as drop-down menus, form validations, hover effects, and more. This helps in creating more engaging and realistic prototypes.


Wappalyzer is a technology proficiency tool that identifies the software, libraries, frameworks, and other technologies that are used on a website. This tool can be installed as a Chrome extension and provides instant insights into what technologies are used to build and maintain a specific website.

Here are some of the tasks Wappalyzer can help with:

  1. Competitor Analysis: Wappalyzer can help you see what technologies your competitors are using on their websites. Understanding this can offer insights into their capabilities and priorities.
  2. Technological Exploration: If you are exploring new technologies to use in your projects, you can utilize Wappalyzer to see what’s popular or trending by analyzing a number of websites.
  3. Learning from Other Sites: If there’s a particular feature or design on a website that you admire, you can use Wappalyzer to identify the technology behind it. This could help you implement a similar feature on your own site.
  4. Sales and Marketing Research: If you’re in a business development role, you can use Wappalyzer to identify potential leads or customers based on their technology stack. For example, if you provide services related to a specific CMS, you can find websites using that CMS and reach out to them.
  5. Security Analysis: By revealing the technologies used on a website, Wappalyzer can help you identify potential security vulnerabilities. For example, an outdated technology might have known security issues.
  6. Web Development: When building or maintaining a website, understanding the current technology stack can help in decision-making about what technologies to keep, replace, or add.

Remember that Wappalyzer can only detect technologies that are publicly exposed. It may not give a complete picture of all the technologies used, especially backend technologies or ones hidden behind content delivery networks (CDNs).


BrowserStack is a cloud web and mobile testing platform that allows developers to test their websites and mobile applications across on-demand browsers, operating systems, and real mobile devices. Although not a Chrome extension, it is a service that can be accessed through any web browser. It’s essential for ensuring websites and applications function correctly across different platforms and devices.

Here’s how BrowserStack can assist you:

  6. Efficiency: Instead of going through the website’s code to identify the font, you can use WhatFont to quickly and easily get this information.

Remember, while WhatFont can help you identify the font being used, it doesn’t provide access to the font files themselves. If you want to use a specific font in your own work, you’ll need to obtain it through appropriate legal channels, like purchasing it from the creator or a font distribution platform, or finding it on a free font website if it’s publicly available.
