Difference between CGI and Servlet

CGI and Servlet are both programming languages used for developing dynamic web applications. While they have some similarities, there are also significant differences between them. In this blog post, we will take a closer look at these two technologies and discuss some of the key differences between them. We will also explore the pros and cons of each approach so that you can make an informed decision about which one is best for your project.

What is CGI?

CGI, or Common Gateway Interface, is a programming language used to create dynamic web content. It allows developers to execute commands on a web server, typically by transmitting information gathered from a user back to the server. CGI can be used in a wide range of applications, such as automated email requests, live chat, or data management functions. CGI is a powerful and highly versatile tool for building engaging web content, and it is one of the key technologies used in modern websites and online applications. Whether you are designing a simple landing page or building the next big social networking platform, CGI has what you need to create dynamic and effective web experiences.

What is Servlet?

Servlets are a type of software that is used to create dynamic web content. Servlets are commonly used in server-side programming, where they allow you to process requests and respond to them using Java code. Servlets have a wide range of applications and are typically integrated with other technologies such as JSP, JDBC, and JSTL. They can be used for everything from creating customized data input interfaces on web pages to building complex e-commerce websites. Whether you’re new to programming or an experienced developer, the possibilities with servlets are endless. So if you’re looking for a powerful tool for building dynamic web content, look no further than servlets.

Difference between CGI and Servlet

CGI and servlets are two different technologies that are commonly used to build web applications. CGI is a scripting language that processes user requests, while servlets are small applications written in Java that run within web servers. CGI requires additional processing on the server-side for every request, which can lead to slower performance and higher resource usage. In contrast, servlets only need to be run once for each user request, making them more efficient and easier to scale than CGI. Overall, CGI and servlets are complementary technologies that can be used together to create robust web applications. Whether you need powerful scripted logic or fast processing of multiple concurrent requests, CGI and servlets have you covered.


CGI and Servlet are two different technologies used for web development. CGI is a scripting language that runs on the server, while servlets are Java classes that run inside a servlet container. They both have their own advantages and disadvantages, but which one you should use depends on your specific needs.
