CircleCI

CircleCI is a leading continuous integration and continuous delivery (CI/CD) platform that helps software development teams automate their build, test, and deployment processes. Founded in 2011 in San Francisco, CircleCI offers both cloud-based and self-hosted solutions to meet various organizational needs. The platform supports multiple programming languages and frameworks, including Ruby, Python, Node.js, Java, PHP, and .NET, as well as various operating systems like Linux, macOS, Windows, and Android. CircleCI's core functionality revolves around automatically building and testing code changes whenever developers commit updates to their version control system, such as GitHub, Bitbucket, or GitLab.

CircleCI's platform is designed to increase developer productivity and improve software quality through features like parallel testing, customizable workflows, and advanced caching. Its Insights dashboard provides users with detailed analytics on pipeline performance, allowing teams to identify bottlenecks and optimize their CI/CD processes. The platform also offers orbs, which are reusable packages of CircleCI configuration, enabling teams to share and standardize their CI/CD practices across projects. In April 2023, CircleCI introduced several security enhancements, including config policies for flexible compliance, AirGap support for isolated networks, and granular secret management features.

Key customers and partnerships

CircleCI serves thousands of global companies across various industries. Notable customers include Cisco, Peloton, and HashiCorp. As of November 2022, CircleCI reported empowering more than 2 million developers across 230,000 teams. The company has established partnerships with major technology providers to enhance its ecosystem. In February 2023, CircleCI joined the Datadog Marketplace, allowing mutual customers to integrate CircleCI events into their Datadog monitoring and observability workflows. This partnership enables teams to optimize their CI/CD pipelines by detecting and resolving error-prone jobs and flaky tests that can cause build errors. CircleCI has also formed integrations with other prominent tools and services, including AWS, Arm, New Relic, and 1Password, to provide a comprehensive CI/CD solution for modern software development teams.
