## What it is
Jenkins is the leading open-source automation server, built in Java, used for continuous integration and continuous delivery of software. It is highly extensible with over 2,000 plugins and supports pipelines-as-code for building, testing, and deploying projects.

## Use cases
- set up a ci/cd pipeline for my project
- automate building and testing my code on every commit
- run automated deployments to production
- self-host a continuous integration server
- orchestrate build jobs across multiple agents
- automate repetitive development workflow tasks
- run static code analysis as part of the build

## When to choose
- you need a highly customizable, self-hosted CI/CD server with a massive plugin ecosystem
- you want pipelines-as-code with Groovy-based Jenkinsfiles
- you need to automate builds, tests, and deployments across diverse toolchains and platforms
- you require fine-grained control over build agents, including Kubernetes-based agents

## When to avoid
- you want a zero-maintenance hosted CI service with minimal setup
- your team prefers modern YAML-based pipeline configs over Groovy
- you only need simple CI for a small project and a lighter-weight tool would suffice
- you are not prepared to manage plugin updates and server maintenance
