Jenkins has been a reliable CI/CD tool since I first learned it while studying programming and microservices seven years ago, and returning to it across several projects since has reinforced how flexible and extensible it is. Being open-source with a massive plugin ecosystem has made it adaptable to nearly any tech stack or workflow, whether that's simple build automation or more complex multi-stage deployment pipelines. Pipeline-as-code through Jenkinsfiles has made version-controlling the entire CI/CD process straightforward, keeping build logic alongside the actual codebase rather than living in a separate system. The community support and documentation, built up over years of widespread adoption, means troubleshooting rarely takes long since most issues have already been discussed somewhere.

The interface feels dated compared to more modern CI/CD tools, and navigating plugin configurations can get cluttered as a project's pipeline complexity grows. Managing and updating plugins over time requires ongoing maintenance, since compatibility issues between plugins occasionally surface after updates. Setting up more advanced pipelines still requires a fair amount of Groovy scripting knowledge, which adds a learning curve for team members newer to Jenkins specifically. Self-hosting means taking on infrastructure maintenance responsibility that some newer, managed CI/CD platforms have abstracted away entirely. Review collected by and hosted on G2.com.
