On Code Cloud, developers can create, manage and share their own code projects, as well as participate in other open source projects. In addition, Code Cloud also provides some advanced services for enterprises, such as private code warehouses, advanced project management tools, etc.
For domestic developers, Code Cloud provides faster access speeds and services closer to domestic habits, making it a good choice.
6. CodePen
CodePen is packed with features and takes a community approach to sharing and showcasing code. This makes it a go-to resource for learning programming tips from other users. As you make progress in programming yourself, you can share it here too. The Skillcrush development team particularly likes using CodePen because it's really useful.
Combinations of HTML, CSS, and JavaScript code that users post on CodePen are called "Pens." Other users can view these "Pens", comment on them, and modify or update the original code after it is published.
To help users create these "Pens", CodePen provides a free built-in text editor. This editor has many features, such as syntax highlighting (which displays text in different colors depending on the type of code), Emmet (which is a tool that can quickly convert short codes into complete codes), and find and replace functions. This makes it easy for users to find content in the code.
In addition, when you modify the code in the editor, CodePen has a real-time preview area on the screen that can immediately display the effect of the code modification.
7. SourceForge
One of the most important open source websites on the Internet is SourceForge. Whenever you need to look at sample code to see how something is done, this is a great place to look.
Hover over the "Open Source Software" tab on the home page and select "Develop." You'll be amazed at the vast universe of open source projects you discover.
There are over 100,000 listings under the "Development" heading in SourceForge, probably one of the largest collections of free code samples and example snippets.
If you come across software that piques your interest, you might consider contributing to the project by joining the development team. You can simply browse the source code to understand how it works.
8. OSDN
Open Source Development Network is called OSDN. It provides many free services to developers of open source software. The services provided include: SVN/Git/Mercurial/Bazaar/CVS warehouse, mailing list, bug tracking software, message board and forum, website hosting, release file download service, file archiving, full backup, shell environment, etc.
More than 55,000 projects use OSDN services. As a user, you can use OSDN to find and download open source software. You can browse and download software in multiple categories on their download page.
9. Code My UI
Code My UI is a treasure trove of code snippets that can help enhance your designs, whether you're looking for ideas to brighten up a bland user interface or thinking about how to implement a certain design for your website. Unlike user communities like CodePen or Stack Overflow, Code My UI doesn't have any social media features or forums. However, what it lacks in interactivity, it makes up for with a simple list of useful code applications.
Code snippets on Code My UI are not posted directly by users, but are collected by site administrators from other code repository sites. Unlike repository sites that require browsing forum posts or Q&A, Code My UI presents code snippets in a simple and straightforward format, including the snippet's name, description, a link to the original source, and most importantly, an example of the code actually running.
10. CodeGuru
Developers can benefit from access to CodeGuru. It is a collection of tools and references that focuses primarily on Visual C++/C++, .Net/C#, and Visual Basic, but also contains a wealth of information on other topics such as Java, Azure, IoT, and more.
Although there aren't a lot of programming languages to choose from, this site provides more in-depth material than the regular forum posts on other sites. CodeGuru's samples provide very detailed guidance on how to complete specific tasks, making them ideal for beginners.
11. FossHub
In 2007, FossHub was founded to provide users with a reliable place to get their favorite software and become a reliable partner for specific free projects.
It offers fast global servers and optimized pages to provide users with a good experience and fast download times. They provide you with direct download links without multiple page redirects.
