Top Live Online Utilities Every Software Developer Should Know

TIO is a family of online interpreters for an ever-growing list of practical and recreational programming languages.

To use TIO, simply go to the site, pick a programming language, and start typing. Once you click the run button, your code is sent to a TIO arena, executed in a sandboxed environment, and the results are sent back to your browser. You can share your code by generating a client-side permalink that encodes code and input directly in the URL.

  • TIO hosts 96 practical and 172 recreational programming languages, for a total of 268 languages.
  • TIO listens: languages and features are added by request all the time. If you have a request or want to report a bug, use any of the contact options in the contact options listed below.
  • The TIO web app is free of charge, ad-free, and doesn’t use tracking cookies or third-party analytic scripts.
  • The software that powers TIO is open source (MIT) and can be found on
  • TIO works great on mobile devices.

Plunker is an online community for creating, collaborating on and sharing your web development ideas.

  • Speed: Despite its complexity, the Plunker editor is designed to load in under 2 seconds.
  • Ease of use: Plunker’s features should just work and not require additional explanation.
  • Collaboration: From real-time collaboration to forking and commenting, Plunker seeks to encourage users to work together on their code.
  • Real-time code collaboration
  • Fully-featured, customizable syntax editor
  • Live previewing of code changes
  • As-you-type code linting
  • Forking, commenting and sharing of Plunks
  • Fully open-source on GitHub under the MIT license

JS Bin is a tool for experimenting with web languages. In particular HTML, CSS and JavaScript, but JS Bin also supports other languages too (like Markdown, Jade and Sass).

JS Bin is ultimately a code sharing site. Along with the code, the complete output of the code is also shared with other developers, colleagues and/or students. As you type into one of the editor “panels”, you and anyone watching your bin will see the output being generated in real-time in the output panel.

CodePen is a place to write and share front-end code. Write HTML, CSS, and JavaScript and get a real-time preview. You can use CodePen to:

  • Show off the amazing things you build.
  • Learn new things by tinkering.
  • Build reduced test cases to report bugs and get help on tricky problems.
  • Try out new technologies for the first time.
  • Build components to later use elsewhere.

The possibilities are endless. Everything you do is saved on CodePen, so the more you use it the more useful it becomes.

This is also one of the same kind of tool as same as JSBin.

A tool for easy online testing and sharing of database problems and their solutions.

If you do not know SQL or basic database concepts, this site is not going to be very useful to you. However, if you are a database developer, there are a few different use-cases of SQL Fiddle intended for you:

  • You want help with a tricky query, and you’d like to post a question to a Q/A site like StackOverflow.
  • You want to compare and contrast SQL statements in different database back-ends.
  • You do not have a particular database platform readily available, but you would like to see what a given query would look like in that environment.

It has been developed by group .Net developers who are sick and tired of starting Visual Studio, creating new project and running it, just to test simple code or try out samples from other developers.

This tool was inspired by, which is just awesome.

Apart from the language and web technologies related tool, we also have some dedicated tools to create, test and share regular expression!

– supports javascript, ruby, .Net

– supports php, javascript, python, golang

CodeBeautify is an online code beautifier which allows you to beautify your source code

Provides many utilities like JSON/XML/HTML/SQL formatter, validator, editor, minifier, etc…… and what not, just go there and explore!!! I have just told you the tip of the iceberg!

Dex_dexter_174x252_(1)Credits for the details go to the amazing creators of the tool themselves!! – I am just a person sharing the lights of this awesome utilities.

Simplify your life with batch scripts

There are many ways your can simplify your regular day to day activities using windows/dos commands or shell scripts if you are using Linux. Here is the way you can start thinking about how you can do it!

Delete temporary files from your machine

Many times you want to delete the temporary files from your machine. So need to first of all go to the temporary files’ folder – ‘C:\Users\<UserName>\AppData\Local\Temp‘ (or just run –> %temp% –> enter; if you know it 🙂 ), select all files and then delete it.

Well, how about creating a batch script once, and just execute it whenever you want to do so, isn’t it a great idea?

Copy the below commands as a TempDelete.bat file, save it on your desktop (or wherever you you feel life saving it), and just double click on it whenever you want to clear your %temp% folder!

cd %temp%
del /s /q .
rmdir /s /q .

The first line opens up the DOS command prompt temporary files’ folder, the second command deletes all the files not in use currently and the third command removes all the child folders.

Just FYI, /q disables Yes/No prompting and /s optilon deletes the file(s) from all sub-directories.

Getting latest files from TFS version control system

If you are a developer, multiple people are working within your team and are doing code check-ins extensively, you must have to keep the local version of the code in sync with the version control system, right?

The people doing this regularly would be able to easily co-relate. If you are using Visual Studio, you need to reach to your project subfolder (and to reach at that folder too, you need to do multiple clicks, wait for folder to get updated with the child folders and files) and then right click, ‘get latest files’.

Well, there is a better way. Just create a batch file once, reach to the folder in the command prompt and get latest files using TF.exe command. When you are using Visaul Studio TFS GUI, the same commands are getting executed behind the scenes.

cd C:\path\to\mapped\folder\api
"<PathToIde>\TF.exe" get $/project/code/api/Main/ /recursive
cd C:\path\to\mapped\folder\web
"<PathToIde>\TF.exe" get $/project/code/web/Main/ /recursive

Copy the above commands and save it as a .bat file, update the <PathToIde> depending on the Visual Studio version you have installed and your OS.

For Windows 7-64 bit, Visual Studio version 10, its

%ProgramFiles(x86)%\Microsoft Visual Studio 10.0\Common7\IDE\TF.exe

Find out where TF.exe is located on your machine and update it.

The good thing is, if you are having a conflict between the source control version and the local version, this command also provides you a GUI to solve it!

Isn’t this great?!


Now just call this batch file from your command prompt, and get the latest version of files from all the project in single batch script. You’ll never know how much time and efforts you are saving by doing this unless you do this once or twice.
