Code
83 / 100

It is a collection of websites with many different programming languages and databases that let you experiment with your code without using any code editors. The way web developers can build has been fundamentally altered by contemporary trends and web apps. It goes without saying that using an IDE will allow you to code new files and save them for deployment. How about simply testing your code samples? Today, there are more tools than ever before!

I’ll list ten engaging web applications for online code testing in this article. All of these programs need to be connected to the Internet, and several of the more sophisticated editors have pro plans that let you improve your account’s features. However, the majority of these tools will undoubtedly be useful when you’re rushing to debug a JavaScript or PHP block.

Codepen

Codepen

CodePen is more of a social media platform than a simple coding environment for Web developers. In addition to seeing people’s shared HTML, CSS, and JavaScript codes, or “Pens,” we can also “Like” the Pen, leave a comment, organize a collection of Pens, publish a post, and participate in challenges to advance our Web development skills.

JSBin

JSBin

Justin is a straightforward JavaScript debugging console, similar to the one described above. In their proposal, they talk about writing together in real-time via a private link that you can share with other devs.

For new users, their interface could be a little complicated. If you’re interested, you can browse through some online tutorials that the developers have set up. Basically, there are dozens of JS libraries to pick from, like jQuery, JQuery UI, jQM, Prototype, and MooTools.

The draughts will automatically save as you code various elements. You have the choice of downloading your finished project or online archiving of the source code. Their approach for exporting and maintaining your code as a blank template is far more sophisticated.

jsFiddle

jsFiddle

Anyone who has perused Stack Overflow must be familiar with jsFiddle. Their interface differs greatly from JSBin’s, and they also support more advanced functionalities.

You can immediately create a free account and begin saving your code samples online. You can share the short URL that jsFiddle provides on Twitter, Facebook, and even Stack. But take note—you don’t need a user account to begin programming. Just an efficient feature to keep everything in order.

Libraries like Prototype and jQuery are also supported by jsFiddle. Each testing document can contain extra external resources in addition to JS and CSS files.

jsFiddle

jsFiddle

A completely functional JavaScript playground is called Codesandbox. You can execute a functioning Node.js application in addition to Vanilla JavaScript code or a framework like React.js, Vue.js, or Svelte. It implies that the package.json file can be used to provide Node.js dependencies. Dependencies from NPM will be downloaded automatically by Codesandbox. Additionally, you get access to a web-based Terminal through which you may execute any NPM scripts directly from your browser.

WebMaker

WebMaker

A code playground for HTML, CSS, JavaScript, and preprocessor languages like Sass, LESS, and JSX is WebMaker. This pre-processor syntax will be automatically compiled by WebMaker so that the code is rendered correctly in the browser. To continue playing with code when offline, utilize the browser extension or install it on Chrome. It allows you to save your work locally, download the files, or share it on CodePen after you’ve finished experimenting with your code.

CSSDesk

We have CSSDesk as we go from the world of scripting to stylesheet language. Your configuration is the same as everyone else’s, with the finished webpage render on the right and your source code on the left. With gradients and box shadows, this web tool is excellent for creating small webpage designs and testing the more complex CSS3 properties.

You may also download source code as files to your PC with this app. If you’re using a laptop without any IDE software, it can be a reliable replacement. You might also create a brief URL link to post online. Then, other programmers might enter and edit what you’ve previously done. This is unquestionably an intriguing solution!

IDEOne

Another tool with a deep programming and software development foundation is IDE One. Some fairly well-known languages have syntax highlighting included in their online editor. There are numerous others, such as Objective-C, Java, C#, VB.NET, and SQL.

Their tool is fantastic since it allows you to quickly debug a variety of programming languages from a single page. This source code can also be kept and shared online via a special URL. However, I do think that their website’s design is clogged up with advertisements and other content, which makes using it challenging. The opportunity to use alternative code libraries, such as Cocoa Touch for iPhone app development, would be incredibly amazing.

JSLint

JSLint is unquestionably the self-described “JavaScript Code Quality Tool.” Although their website is a little odd, the code editor functions as you would expect it to.

If you haven’t utilized their framework before, you could find the alternatives to be extremely perplexing. If you have the necessary expertise, you can work with open-source software such as Node.js. However, a significant portion of the source code doesn’t even enable syntax highlighting, which is disappointing given the abundance of available alternatives. If you have the time, I recommend looking at JSLint, however, it might not end up being your primary online JavaScript debugger.

SQL Fiddle

The strength of a web application like jsFiddle was demonstrated earlier. Now, we can see how SQL Fiddle operates, albeit without the SQL database syntax. This is by far my favorite option because I haven’t found a better one for testing database stuff.

Your SQL code’s complete output will be displayed in a table below the editors. On the right, you can implement new data, and on the left, you can create a schema by writing some code. You can save the SQL code for this database schema and use it to export your current database for installation on a new server.

If you aren’t familiar with databases or SQL language then this app won’t be much assistance. But even for developers who are new yet interested in learning SQL, this is brilliant! Check out one of their basic code examples so you can get an idea of how the app works.

ESLint Demo

PHPStan

PHPStan is a tool for static analysis of PHP code. Without running the code, it looks for potential problems and coding errors. It will let you know if you access a property that doesn’t exist on a class or send a string value to a function that only accepts integers, for example.

To see how it functions, use the online editor on the PHPStan website. You’ll be astonished to see how many PHP programs now in use can be improved upon and fixed for potential flaws. Static analysis teaches you to produce syntactically accurate code, which helps you become a better developer.

OneCompiler

a multi-language compiler that is all-inclusive. It supports more than 40 languages, including C and C++ as well as Go, PHP, Java, and JavaScript. Various tools allow you to write code in these languages, and the code will be immediately compiled and executed. This tool is ideal for fast testing your code for a demo or just for carrying out a test.

This application, in addition to the code runner, offers code challenges to help you hone your programming and problem-solving abilities. Starting points for the challenge range from the easier levels to the more difficult ones.

Jsitor

a web-based code editor that supports HTML, CSS, and JavaScript. You also incorporate a number of well-known libraries, like jQuery, React.js, Vue.js, Font Awesome, and many others. It’s a fantastic tool for prototyping ideas without the need to set up a computer environment. It can also be utilized for rapid demos.

It differs from other tools of a similar nature in part because it offers a native app for iOS and Android. This enables you to conveniently pour your thoughts on using your phone and tablet.

Glitch

a web-based code editor that supports HTML, CSS, and JavaScript. You also incorporate a number of well-known libraries, like jQuery, React.js, Vue.js, Font Awesome, and many others. It’s a fantastic tool for prototyping ideas without the need to set up a computer environment. It can also be utilized for rapid demos.

It differs from other tools of a similar nature in part because it offers a native app for iOS and Android. This enables you to conveniently pour your thoughts on using your phone and tablet.

Stackblitz

In the online development environment known as Stackblitz, you can create websites using cutting-edge stacks. It supports the front-end libraries React.js, Vue.js, and Angular as well as the back-end frameworks Next.js and Node.js.

You can either drag and drop a folder onto one of these frameworks to use it as the starting point for your project. It comes pre-configured with features like auto-refresh, installing dependencies, and Prettier that you generally have to set up on your own while working locally on your computer.

In addition to those, you can also link Firebase to your website if you need to access a real-time database.

Codepad

(Codepad is no longer available.)

Codepad is a distinctive web application that Steven Hazel invented that allows you to exchange code syntax online. Codepad gives you the option to copy/paste significant pieces of code for online sharing in addition to debugging.

Any error messages connected to your code are displayed on the output screen. You can switch the parsing language between C/C++, Perl, PHP, Python, Ruby, and a tonne of other languages using the radio buttons on the left-hand menu. Codepad, in my opinion, is best suited for software engineers that need to communicate and troubleshoot their more complex applications.
