The Internet is a vast and deep ocean of possibilities and it’s even more so when you are a developer looking to save time and productivity. That's why many sites aim to make developers' lives easier by offering them useful and efficient tools.

Here is a list of websites to visit if you are a developer to increase your productivity:

1) Small dev tools

Small Dev Tools is a collection of more than 25 tools for developers to help them with common tasks such as coding/decoding, file compression, testing, QR code generation and many more.

Very easy to use with a nice minimalist interface and fast execution speed, it is a perfect tool for developers.

2) Can I Use

Intended for developers and software engineers, Can I Use has the ability to save time when creating websites. Indeed, it does automatic tests of functions and indicates which functionality can run on different browsers.  You'll find the tools you need to get started in web development, machine learning, cloud, cybersecurity, augmented reality, data science or IoT.

Can I Use is so popular, it even got its own extension on Chrome.

3) DevHints

DevHints is an online code library. It is therefore a site centralizing all the cheatsheets. You can find any documentation or explanation to understand a particular function or a particular code. In DevHints, it is simply about helping developers to learn.

4) BundlePhobia

For developers who use JavaScript, there is BundlePhobia. This website tells them the optimal and required size of NPM packages. This is because NPM packages can eat up a lot of disk space quite quickly. This will give you a pretty good idea of the performance of your site as you develop it.

5) CodElf

​​For those who don't want to waste any time, they can also use the CodeElf site. Developers can save time in the sense that it gives real-life variable names to developers. And this, in order to save time, because choosing variable and function names is often time consuming. Even better, CodElf allows you to instantly search on Github, GitLab, Google Code or Bitbucket to see if your name idea will work!

6) DevDocs

DevDocs allows you to have access to all the documents related to all the languages and frameworks, all in one place, in a fluid and organized way. So instead of searching different sites, you have all the documentation you need to code, in one centralized site.

7) Hoppscotch

There are different tools used by developers to test their APIs. The most famous are Postman or Insomnia. But for some time now, Hoppscotch has become a must-have. Indeed, it allows you to test your API directly in the browser, unlike its competitors who sometimes force you to add extensions to your browser.

8) Crontab Guru

In computer language, a Cron is a program that runs in the background. It waits until the time specified in the configuration file, called crontab, to perform the action requested of it before pausing until the next action. This step is often crucial for developers and is one of the most common sources of errors.

Crontab Guru has been launched to remedy this. It will allow you to instantly validate your Cron and alert you in case of error. A practical tool to save time and avoid making mistakes.

9) Unminify

Unminifying code files, whether they are JavaScript, CSS, HTML, XML or JSON can be a tedious and time-consuming task for many developers.

That's why many unminify websites have been created. Among them, Unminify, which has the advantage of offering a very easy to use interface.

As a reminder, "minification is the process of compressing a file by removing unwanted elements, including code, spaces and unnecessary comments, reducing the length of variable names to single characters, which reduces the file size. The files after the minification process are called minified files. This process is essential because it helps us load web pages faster, thus reducing page load times" as explained by DelfStack.com.

10) Slashdot et Github

SlashDot is a huge interactive source of all the latest blog posts and news related to technology and coding. With a true community feel, SlashDot is run by a small group of editors and coders, with the help of the site's strong community of readers. In short, the perfect place to find answers to your questions and find help.

In this same community sharing spirit, there is of course GitHub. GitHub needs no introduction for software developers. It is the place on the Internet where open source projects are built. Developers can share their code with the rest of the world, contribute to open source projects and create websites for free. Note that a good GitHub profile can open up great job opportunities.
