About CircleCI
CircleCI is a continuous integration and continuous delivery (CI/CD) platform that helps development teams automate their software build, test, and deployment pipelines. It supports a wide range of execution environments including Docker, Linux, macOS, Windows, Arm, and GPU, and integrates with major version control systems and cloud providers. CircleCI offers both cloud-hosted and self-hosted (runner) deployment options, making it suitable for startups, SMBs, and large enterprises alike. The platform recently introduced autonomous validation capabilities, including the Chunk agent and an MCP server, to help teams ship trusted code at AI speed.
- Execution Environments: Run jobs on Docker, Linux VM, macOS, Windows, Arm, and GPU resource classes to match any workload.
- Chunk Agent: Autonomously maintains and fortifies pipelines, protecting quality and uptime at scale with minimal human oversight.
- MCP Server: Gives AI assistants access to logs, job metadata, and failure context for faster diagnosis and fixes.
- Smarter Testing: Runs only impacted tests and prioritizes critical paths to cut risk, cost, and time to release.
- Build Optimization: Leverage Docker Layer Caching, parallelism, and caching to dramatically reduce build times.
- Autoscaling: Automatically scale compute resources to meet demand without manual infrastructure management.
- Orbs Registry: Use reusable, shareable packages of YAML configuration to integrate third-party tools in seconds.
- Insights & Flaky Test Detection: Monitor pipeline health, identify flaky tests, and track performance trends over time.
- Config Policies: Enforce org-wide governance and standardization with policy gates baked into every pipeline (Scale plan).
- Self-Hosted Runners: Run jobs on your own infrastructure for hybrid deployments with full control over the execution environment.
- Deploys Dashboard: View and manage deployments across your organization from a single dashboard with no infrastructure access required.
- Rollback Pipelines: Set up automatic rollbacks with jobs and approvals so failed releases revert quickly and safely.
