CircleCI: Continuous Integration & Delivery Platform
CircleCI helps developers automate building, testing, and deploying applications with cloud-based infrastructure for running jobs in Linux containers, along with analytics and monitoring insights.
What is CircleCI?
CircleCI is a continuous integration and delivery platform designed to help developers build, test, and deploy applications with speed and confidence. It provides cloud-based infrastructure for running automated jobs in Linux containers, allowing code to be built, tested, and delivered rapidly and reliably.
Some key features of CircleCI include:
- Automated building, testing and deployment pipelines to accelerate delivery of applications
- Insights through dashboards and analytics to identify bottlenecks and improve developer productivity
- Flexible configuration with YAML-based circleci config to customize workflows
- Convenience with pre-built Orbs that make setting up common workflows faster
- Scalability to meet the needs of small teams or the largest enterprises
- Integration with GitHub, Bitbucket and other tools in the development ecosystem
By handling tedious tasks like setting up test environments and deployment in a repeatable way, CircleCI enables developers to focus on writing code rather than managing infrastructure. Its containers-based approach also makes it easy to replicate issues locally. Leading organizations like Spotify, Coinbase, Stitch Fix, and Blue Apron use CircleCI to build, test and deploy code rapidly and reliably.
