CircleCI

What CircleCI is

CircleCI is a continuous integration and continuous delivery platform. Pipelines are defined in configuration files and can be reused through Orbs, with execution environments spanning Docker, Linux, macOS and Windows, and both cloud and self-hosted deployment.

An insights dashboard provides monitoring and analytics on builds.

What you can do with it

• Build, test and deploy on every commit
• Reuse pipeline configuration through Orbs
• Run jobs across several platforms
• Track build performance over time

Who it is for

• Development teams automating delivery
• Organisations practising DevOps
• Teams needing cloud and self-hosted options

What to watch out for

• Pipeline secrets and deployment credentials are high-value targets; scope them and rotate them
• Self-hosted runners mean you maintain the infrastructure and its patching
• Configuration complexity grows quickly on large monorepos
• Build minutes and concurrency limits drive cost
