⚡ What is Jenkins?

Jenkins is an open-source automation server that was initially released in 2011 by Kohsuke Kawaguchi. It’s designed to automate the software development process, supporting everything from building and testing to deploying applications, serving development teams of all sizes. With a vast community and extensive plugin ecosystem, it’s a go-to for continuous integration and continuous delivery (CI/CD). Its strength? Highly customizable and extensible.

💰 Jenkins Pricing

Jenkins is an open-source tool and is completely free to use. There are no subscription fees or licensing costs associated with Jenkins itself. However, users should consider the infrastructure costs (servers, storage, etc.) required to run Jenkins.

Plan	Cost	Features Included	Best For
Open Source	Free	All features and plugins	All users and projects
Infrastructure	Variable	Server costs, storage, etc.	All users

Pricing Details: While Jenkins is free, remember to account for server and maintenance costs. Methods: Download and install on your own infrastructure or use cloud-based solutions. Tip: Start with a small setup and scale as needed to manage costs effectively.
