10 Useful playgrounds for a web developer

Introduction

Ever face a situation when you want to execute some code, but don’t want to create a new project or sometimes don’t want to set up the environment?

Relax, it’s a normal thing almost every developer feels at the moment.

We will look over some online playgrounds, using which you can consistently execute the code without worrying about setup. It can be easily saved and shared with other developers even!

Playgrounds

DB fiddle — for Mysql and PostgreSQL
Mongo playground— for MongoDB
Go playground — for Golang
Codepen — for HTML, CSS, and js
Tailwind Play — for tailwind CSS
Tutorials point — for python
Online PHP — for PHP
Playcode.io — for HTML, CSS, js, and all-purpose playground including frameworks
CodeSandbox — for HTML, CSS, js, and all-purpose playground including frameworks
Font playground — For trying various font styles

1. DB fiddle

It provides an interactive UI for running SQL queries like Mysql and PostgreSQL.

The key benefit of using it is you can execute queries using different versions of Mysql, without adding effort to install multiple versions.

For example, you want to test the MySQL query in MySQL 5 and in MySQL 8 as well. DB fiddle facilitates us to switch between the versions.

It comes with features like,

To save and share with others
To switch between different versions of MySQL
To collaborate with others
Allows to update schema and queries

3. Go Playground

It allows you to write and execute Go programs when you want to test something before actual implementation.

It provides functionalities like,

To use the specific go version(1.18 or 1.19)
To format the code
To share it with others
Provides default implemented programs like Hello world, a program to print the Fibonacci series, etc which can be helpful for beginners.
Include some tabs like Go packages, docs, blogs, why to choose Golang, etc.

Along with allowance for,

Save and share with others
Fork sandbox to Github(link Github)

Font size
Font weight

Also, it shows code for whichever effects you have applied and facilitates exporting it to your favorite online playgrounds like Codepen!

Closing Thoughts

We don’t always need to configure an environment for executing the code of different languages or frameworks. The online playground can be the best workaround!

Almost all tech-savvy people are using it for demonstrating something, that is not so long and just for demo purposes(you had definitely found playground links on StackOverflow and also in developer communities 😄).

keep playing with playgrounds!!
