# GitLab CI/CD **(FREE)**
GitLab CI/CD is a tool built into GitLab for software development
through the [continuous methodologies](introduction/index.md):
- Continuous Integration (CI)
- Continuous Delivery (CD)
- Continuous Deployment (CD)
NOTE:
Out-of-the-box management systems can decrease hours spent on maintaining toolchains by 10% or more.
Watch our ["Mastering continuous software development"](https://about.gitlab.com/webcast/mastering-ci-cd/)
webcast to learn about continuous methods and how the GitLab built-in CI can help you simplify and scale software development.
Continuous Integration works by pushing small code chunks to your
application's codebase hosted in a Git repository, and to every
push, run a pipeline of scripts to build, test, and validate the
code changes before merging them into the main branch.
Continuous Delivery and Deployment consist of a step further CI,
deploying your application to production at every
push to the default branch of the repository.
These methodologies allow you to catch bugs and errors early in
the development cycle, ensuring that all the code deployed to
production complies with the code standards you established for
your app.
GitLab can also automatically detect, build, test, deploy, and
monitor your applications by using [Auto DevOps](../topics/autodevops/index.md).
For a complete overview of these methodologies and GitLab CI/CD,
read the [Introduction to CI/CD with GitLab](introduction/index.md).
