Method 4: Via Terminal
If you prefer using the command line interface and have advanced knowledge of your Mac’s system, you can also view the source code of a web page using Terminal.
1. Open Terminal on your Mac.
2. Type in the following command and press Enter:
"`
curl
"`
Replace `
3. This will retrieve the HTML source code of the webpage and display it in the Terminal window.
4. You can further manipulate and analyze the source code using command line tools like `grep` or redirect the output to a file for further analysis.

Why Can’t I View Source Code on Some Websites?
Sometimes, you may encounter situations where you are unable to view the source code of certain websites. Here are a few reasons why this might happen and potential fixes:
1. Q1: Why can’t I view the source code of a password-protected website?
A: Password-protected websites often use server-side rendering or client-side JavaScript to dynamically generate and encrypt the content. In such cases, the source code will not contain the decrypted content, making it inaccessible through the usual methods. To view the source code, you may need to obtain the decrypted content by logging in or using specialized tools for capturing network requests.
2. Q2: Why can’t I view the source code of a website that heavily relies on JavaScript?
A: Some websites heavily rely on JavaScript to generate and modify their content dynamically. As a result, the source code may not contain the final rendered HTML markup. In these cases, you can still inspect and analyze the JavaScript code responsible for generating the content using the browser’s developer tools.
3. Q3: Why can’t I view the source code of a webpage that uses obfuscation techniques?
A: Some websites employ obfuscation techniques to obscure their source code, making it difficult to understand and analyze. These techniques aim to protect intellectual property or prevent unauthorized modification. If you encounter obfuscated source code, you can try using JavaScript deobfuscation tools or consult the website’s documentation or developers for further assistance.
Implications and Recommendations
When viewing the source code of a website, it’s important to understand that it should be done for educational and learning purposes, or when troubleshooting issues with a particular webpage. It is crucial to respect the intellectual property rights and privacy of website owners and users. With that in mind, here are three recommendations:
1. Familiarize yourself with the basics of HTML, CSS, and JavaScript to better understand the source code you are inspecting. Online resources, tutorials, and courses can be valuable in enhancing your web development knowledge.
2. Explore and experiment with the various features and functionalities offered by the developer tools of your preferred browser. Understanding how to use these tools effectively can greatly enhance your web development workflow.
3. Participate in open-source projects or contribute to the web development community. Collaborating with others and sharing your knowledge and expertise can help you grow as a developer and gain insights into different source code patterns and best practices.
5 FAQs about Viewing Source Code
Q1: Can I modify the source code of a webpage using the browser’s developer tools?
A: Yes, you can modify the source code temporarily using the developer tools, but keep in mind that the changes are local to your browser and will not affect the actual website. The modifications will be lost once you refresh the page.
Q2: Can I view the source code of a website on my iOS device?
A: Yes, there are browser apps available for iOS devices that offer developer tools similar to those on desktop browsers. These apps can be utilized to view the source code on iOS.
Q3: Is it legal to view the source code of any website?
A: Generally, viewing the source code of publicly accessible websites is legal as long as you respect the terms of service and intellectual property rights of the website owners. However, it’s always recommended to use this knowledge responsibly and for educational purposes only.
Q4: Can I use the source code of a website for my own projects?
A: It’s crucial to respect the copyright and intellectual property of website owners. Copying and reusing the source code of a website without proper authorization is a violation of intellectual property rights. If you want to use certain elements or code snippets, it’s best to seek permission or use open-source alternatives.
Q5: Are all websites built with HTML, CSS, and JavaScript?
A: While the majority of websites are built using HTML, CSS, and JavaScript, there are alternative technologies and frameworks available. Some websites may be built with server-side languages like PHP or use content management systems like WordPress, which generate HTML markup dynamically.
Final Words
Viewing the source code of a website can be an enriching experience, allowing you to gain insights into web development techniques, learn from others’ code, and troubleshoot issues. By utilizing the browser’s developer tools or even the command line, you can explore the HTML, CSS, JavaScript, and other resources that power the websites you interact with daily. Just remember to use this knowledge responsibly, respect intellectual property rights, and continue to enhance your web development skills.
