Forrester Research's Q3 2019 report, The Forrester Wave™: Cloud-Native Continuous Integration Tools, highlights CircleCI as a leader in the continuous integration and continuous development (CI/CD) space for the second consecutive time, emphasizing its role as the only standalone CI provider recognized. CircleCI's focus on delivering top-tier CI/CD tools is underscored by its support for various execution environments, including Linux, Windows, and macOS, as well as its innovative orb technology, which facilitates third-party application integration. The report also commends CircleCI for its enterprise compliance support, such as FedRAMP certification, which enhances its credibility and accessibility for federal developers. However, the report identified areas for improvement, such as migration tools, hybrid CI capabilities, and a more comprehensive user experience. Despite these challenges, CircleCI remains a preferred choice for development teams seeking performance-driven and flexible CI/CD solutions, backed by a significant volume of build data and extensive experience in the industry.
