In simple English
Jenkins is a server application that handles repetitive tasks for you. It runs your tests, builds your code, and pushes updates to your production servers. You set up rules for when these tasks should run. It saves you from doing those chores by hand every time you change your code. It is free to use, but you need a server to host it and some time to configure it.
What it is
Jenkins is an open-source automation server built in Java (a popular programming language used to run software on servers and computers) that coordinates software builds, tests, and deployments. It connects to your source code repository (a storage place where your project's files and history live) and triggers workflows whenever new code is added.
What it is good for
Solo builders who want to automatically test their code and deploy updates to their servers without clicking buttons manually.
- Over 2,000 plugins available to connect with almost any external tool or service.
- Supports both frequent weekly updates and stable long-term support releases.
- Free and open-source under the MIT licence (a simple set of rules letting you use, change, and share the software freely).
- Difficult setup and configuration for non-programmers.
- Requires a dedicated server with enough RAM (random access memory, the active workspace your computer or server uses to run programs) to stay online.
- Maintenance can become heavy as your plugin list and pipeline definitions grow.
