Pre-editor's note : Automation, open source tools supported by the developer community are what everyone dreams of. Here are more than 60 of the best open source tools that can help you implement DevOps well.
One, development tools
Version control & collaborative development
1. Version control system Git
Git is an open source distributed version control system for effective and high-speed processing of version management from very small to very large projects.
2. Code hosting platform GitLab
GitLab is an open source application developed with Ruby on Rails, which implements a self-hosted Git project repository, which can access public or private projects through a web interface.
3. Code review tool Gerrit
Gerrit is a free, open source code review software that uses a web interface. Using a web browser, software programmers in the same team can review each other's modified program code and decide whether to submit, return or continue to modify. It uses Git as the underlying version control system.
4. Version control system Mercurial
Mercurial is a lightweight distributed version control system, implemented in Python language, easy to learn and use, and strong in scalability.
5. Version control system Subversion
Subversion is a version control system. Compared with RCS and CVS, it adopts a branch management system. Its design goal is to replace CVS. Most of the free version control services on the Internet are based on Subversion.
6. Version control system Bazaar
Bazaar is a distributed version control system. It is released under the GPL license and can be used on Windows, GNU/Linux, Unix and Mac OS systems.
2. Automated construction and testing
1.Apache Ant
Apache Ant is a tool that automates software compilation, testing, deployment and other steps. It is mostly used for software development in the Java environment.
2.Maven
In addition to its ability to build programs, Maven also provides advanced project management tools that Ant lacks. Because Maven's default build rules are highly reusable, a simple project can often be built with two or three lines of Maven build scripts, while using Ant requires more than a dozen lines. In fact, due to Maven's project-oriented approach, many Apache Jakarta projects now use Maven, and the proportion of company projects adopting Maven continues to grow.
3.Selenium (SeleniumHQ)

4.PyUnit
The Python unit testing framework, PyUnit for short, is a Python version of JUnit designed by two smart guys, Kent Beck and Erich Gamma.
5.QUnit
QUnit is jQuery's unit testing framework.
6.JMeter
JMeter is an open source project organized by Apache. It is a tool for function and performance testing, 100% implemented in java.
7.Gradle
Gradle is a build system that can use Groovy to write build scripts, supports dependency management and multi-projects, similar to Maven, but simpler and lighter than it.
8.PHPUnit
PHPUnit is a lightweight PHP testing framework. It is a complete porting of JUnit3 series versions under PHP5, and is a member of the xUnit test framework family (they are all based on the design of pattern pioneer Kent Beck).
Three, continuous integration & delivery
1.Jenkins
The predecessor of Jenkins is Hudson, which is an extensible continuous integration engine.
2.Capistrano
Capistrano is a tool used to execute the same command on multiple machines in parallel, used to install a whole batch of machines. It was originally developed to publish Rails applications.
3.BuildBot
BuildBot is the most needed software for a system's automated compilation/testing cycle to verify code changes. By automatically rebuilding and testing what changes every time, unnecessary failures are reduced before the construction is quickly identified.
4.Fabric
