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.

It comes with features like,

  • To save and share with others
  • To switch between different versions of MySQL
  • To collaborate with others

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!!
