CI/CD
Overview
What CI/CD is
CI/CD stands for continuous integration and continuous delivery or deployment. Continuous integration means developers merge code frequently, and each merge triggers an automated build and test run so conflicts and bugs surface immediately. Continuous delivery keeps that tested code always ready to release; continuous deployment goes further and pushes every passing change to production automatically.
How a pipeline works
A CI/CD pipeline is a defined sequence of automated steps triggered by a code change: install dependencies, build, run tests, and deploy. Tools like GitHub Actions, GitLab CI, and CircleCI run these steps on every commit or pull request. If any step fails, the pipeline stops and alerts the team before broken code reaches users.
Why it matters
CI/CD replaces slow, error-prone manual releases with a repeatable, automated process, so teams deploy confidently—often many times a day. In our web, app, and SaaS development projects, our in-house team sets up pipelines that test and deploy on every merge, catching regressions early. The result is faster delivery, fewer production incidents, and a clear audit trail.

FAQ
CI/CD — common questions
What is the difference between CI and CD?
CI (continuous integration) automatically builds and tests code each time it's merged. CD refers to continuous delivery—keeping tested code ready to release—or continuous deployment, which automatically pushes every passing change to production. CI comes first; CD extends it to releasing.
What tools are used for CI/CD?
Common tools include GitHub Actions, GitLab CI/CD, Jenkins, CircleCI, and Azure Pipelines. The right one usually depends on where your code lives; teams on GitHub, for example, often use GitHub Actions because it's built in.
Do small teams need CI/CD?
Yes—arguably more than large ones. Even a lightweight pipeline that runs tests and deploys automatically saves time and prevents mistakes on every release, and it scales as the team grows.
