5 Tools That Every Front-End Developer Needs


Front-end development is an exciting and continually evolving field. As exciting as it can be, it will be equally challenging if we don’t have the necessary tools in our kit. In this blog post, we’re going to look at five such indispensable tools that every front-end developer needs to know about:

GitHub Codespace

GitHub Codespace is a development tool that provides an integrated and seamless environment to write, run, debug, and deploy code directly in your browser. Codespace connects to your repositories, allowing for easy cloning and editing of the codebase in a pre-configured VS Code editor. Hence it eliminates the need for a local environment setup and offers the ability to start coding instantly on a newly cloned repository.

Since it’s built on Visual Studio Code, it offers all the capabilities of VS Code, such as IntelliSense, live share, and thousands of extensions to enhance your development workflow. Plus, the fact that it’s cloud-based means you can work on your projects from any location or device, increasing flexibility and mobility.

It is an ideal tool when collaborating with a team, ensuring that everyone works within the same development environment, hence avoiding the “it works on my machine” conundrum.


Now the code is in your VSCode editor. You started to make changes and create your own version of the web app. How do you test the performance of the application before you push your code to the server? That’s when Google’s own Lighthouse Chrome extension comes in.

Lighthouse is a fantastic tool for checking the performance of a web page. It audits for performance, accessibility, progressive web apps, SEO, and more. Front-end developers need Lighthouse to ensure their applications not only look good but also work efficiently.

This tool helps front-end developers create high-quality web pages that load quickly, are accessible to all users, and rank high in search engine results. All of these factors can significantly impact a site’s user experience and overall success.


You’re asked to show a quick prototype of what you’ve been doing with your repo. Now, instead of building something from scratch, imagine a tool that lets you immediately help you build a prototype and share it with your manager. That’s what CodePen does.

CodePen is an online community for testing and showcasing user-created HTML, CSS, and JavaScript code snippets. It’s a social development environment for front-end developers, allowing them to create and share compelling UI elements. Developers can use CodePen to create prototypes, test out new ideas, or even as a live portfolio to showcase their skills to potential employers or clients.


Most of our development happens in a local environment, and showing a demo of what you’ve built will need you to redo whatever you did on the local machine on the server. It takes too much time and feels overkill if you just want to demo your code. ngrok solves that same problem by creating secure tunnels to localhost and making your locally hosted app or website accessible over the internet. As a front-end developer, you’ll find ngrok invaluable when you need to share your work with clients or colleagues who aren’t on your local network.

This tool is highly beneficial when working in a team or dealing with clients. It allows you to share your work without the need to deploy it first, speeding up feedback cycles. Additionally, ngrok provides detailed insights into the HTTP traffic for your tunnels, making debugging easier.


Now that you’ve cloned your repository, created applications, tested, and deployed them on your own server. How do you monitor the errors that pop up when a user uses your app?

Enter Sentry

Sentry is an open-source error-tracking tool that helps developers monitor and fix crashes in real-time. It simplifies debugging by providing detailed information about issues as they occur. For a front-end developer, Sentry is a lifesaver, as it can point out where the problem lies in the code, saving a significant amount of debugging time.

Sentry is essential for maintaining the quality of your applications by detecting issues quickly and ensuring a smooth user experience.

And a bonus point.


Requestly is an open-source tool that fastrack your web development process 10x. As a front-end developer, it can be useful to test different server responses, rewrite URLs for local development, or even modify headers. You can also use Requestly to mock server responses when you want to test how your application behaves under different data conditions, making it easier to catch issues before they reach your users.

These tools provide front-end developers with a comprehensive set of functionalities that are indispensable in every stage of the development process. By incorporating these tools into their workflows, front-end developers can save time, increase productivity and collaboration, and ultimately deliver better user experiences.
