TeamCity is a build management and continuous integration/continuous delivery (CI/CD) server developed by JetBrains.[2] First released on October 2, 2006, TeamCity is designed to help development teams automate the build, test, and deployment processes for software projects across multiple platforms and technologies.[3] TeamCity operates under a freemium licensing model, offering a free tier with up to 100 build configurations and three Build Agent licenses, while open-source projects can request completely free licenses. Enterprise features require paid licensing.
TeamCity serves as a centralized platform for DevOps practices, enabling teams to implement continuous integration and continuous delivery workflows. The system monitors version control systems for changes and automatically triggers builds, tests, and deployments based on configurable rules and triggers. Its web-based interface provides comprehensive visibility into build status, test results, code quality metrics, and deployment pipelines. The platform is built using Java and runs as a server application that can be deployed on-premises or in cloud environments. TeamCity supports distributed build processing through its Build Agent architecture, allowing teams to scale their CI/CD infrastructure across multiple machines and environments.
Key Features
Build Management
Flexible Build Configurations: Support for complex build chains with dependencies, parallel execution, and conditional logic
Build Templates: Reusable configuration templates to standardize build processes across projects
Artifact Management: Built-in artifact repository with versioning, cleanup policies, and dependency resolution
Build Triggers: Multiple trigger types including VCS changes, schedule-based, dependency-based, and manual triggers
Build Parameters: Configurable parameters for environment-specific builds and deployments
Continuous Integration & Testing
Gated commits: Pre-commit validation that prevents developers from breaking the main branch by running builds on proposed changes before they are committed
Parallel Build Execution: Distributed build processing across multiple Build Agents for faster feedback
Test Integration: Native support for major testing frameworks with detailed reporting and history tracking
TeamCity follows a distributed architecture consisting of:
TeamCity Server: Central management component that hosts the web interface, manages configurations, and coordinates builds
Build Agents: Distributed workers that execute build tasks and report results back to the server
Database: Persistent storage for build history, configurations, and metadata
Artifact Storage: Repository for build outputs, dependencies, and deployment packages
This architecture enables horizontal scaling and supports hybrid cloud deployments.
