40 Sites to find, share & test code snippets online

When you are working on a project, often you come across the need for a block of code that performs a certain function, or display a certain layout.

Some 10 years ago the choices were limited for developers to find such code. The developer had to either create the block himself or post in a community forum in the hope that someone will help him out, or search big code repositories like sourceforge, GitHub etc. That was tiresome.

Now we have websites created specially for the purpose of writing, testing and sharing code. Most such sites are free to use, but some operate a freemium model where basic options are free but paid upgrades give you more options to manage your code.

The Sharing option can be private or public depending on the access level, or the package that you buy (if it is a paid code sharing website).

Code sharing and hosting sites are of the following types

• Simple text editors where you can write any type of code. You can save and share the code with a link. Typically there is no option to test the code.
• JavaScript code testing and sharing websites. These websites offer online editors to write and test Java Script code live. You also get links to share your code snippets.
• CSS code testing and sharing websites. These sites offer online editors to write and test CSS code live. You also get links to share your CSS code snippets.
• Websites where you can write and test programming languages like PHP, Java, C, C++ etc.
