Golang (Go) is an open source programming language that was developed by Google in 2007 and officially released in 2010. It is a static language that is efficient, concise, and easy to deploy, so it is very popular among developers. However, open source does not mean that everything is free. Let’s take a look at Golang’s free situation.
First of all, Golang itself is free. Anyone can download Golang’s binary installation package for free on the official website and build their own development environment. At the same time, Golang's source code is also available on GitHub, where developers can obtain, read and modify Golang's source code for free.
Secondly, Golang applications are free according to the application license agreement. The open source nature of Golang allows developers to use it to create free applications. Developers can use Golang to create and distribute free applications, and they can also use it to contribute to open source projects. Therefore, developers can develop with Golang on a free basis as long as they comply with the application license agreement. However, for applications for commercial use, corresponding fees need to be paid according to the agreement.
In addition, Golang’s related tools, frameworks and other resources are also available for free or for a fee. For example, Golang's official IDE, GoLand, requires payment to purchase and use it. Another Golang IDE, VSCode, is free, but you need to pay a certain fee to use some functions. In addition, some of Golang's excellent frameworks, such as gin, beego, etc., also have free and paid versions. The paid version provides more advanced features and technical support.
Overall, the use of Golang is free. However, applications for commercial use require payment of appropriate fees. In addition, Golang's related tools and frameworks and other resources also vary between free and paid. Developers can choose free or paid resources based on their own needs and budget.
For Golang developers, free does not mean low quality or unreliable. Golang, as an open source static language launched by Google, has stable performance and strong security, and is widely recognized and praised among current programming languages. Therefore, for developers who are interested in developing applications, learning Golang is a good choice.
Finally, what I want to emphasize is the free nature of Golang official documentation. Golang's official documentation is very detailed and comprehensive. It contains many excellent tutorials, guides and examples, which can help developers quickly master Golang's syntax and features. These official documents are provided free of charge and anyone can download, read and study them on the official website.
In short, for Golang, we can see that its development and use are free. However, as applications become commercialized, corresponding fees will need to be paid. Therefore, understanding the specific content of the Golang application license agreement and the charging situation of related resources allows us to have a clearer understanding of the difference between free and paid Golang.
The above is the detailed content of Let's talk about Golang's free situation. For more information, please follow other related articles on the PHP Chinese website!

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
