This is a list of essential tools and services from my coding workflow that I think should be part of every web programmer’s toolkit. Whether you a building a simple “Hello World” app or a complex web application, these tools should make your coding easier and increase productivity.

1. Devdocs.io

API documentation for all popular programming, languages and frameworks. Includes
Search and work offline too.

2. codeply.com

Quickly build front-end responsive layouts with frameworks like bootstrap, Materialize CSS and SemanticUI.

3.Regexr.com

A good tool for testing your regular expressions in the browser.

4.glitch.com

create your own web apps in the browser, import GitHub repos, use any NPM package or build on any popular framework and directly deploy to firebase.

5.babeljs.io/repl

Write your own code in modern JavaScript and let Babel transform your code into JavaScript compatible even with older browsers.
