Jenkins
Jenkins is like a digital assistant that helps software teams automate their work. Think of it as a reliable worker who handles repetitive tasks in software development, such as checking code quality, running tests, and releasing new versions of software. When developers make changes to their code, Jenkins automatically processes and tests these changes, making sure everything works properly before it goes live. This saves time and reduces human error. It's similar to other tools like TeamCity or GitLab CI, which all help make software development more efficient and reliable.
