What Is TeamCity? Guide to CI/CD Tool by JetBrains

What is TeamCity?

TeamCity is a CI/CD and build management system developed by JetBrains, the company behind popular tools like IntelliJ IDEA, PyCharm, and WebStorm.

TeamCity helps automate the process of building, testing, and deploying code, making it easier for development teams to deliver high-quality software at speed.

Key Highlights:

• Developed by: JetBrains
• Programming languages and frameworks: Java, .NET, Ruby, and more
• License: Freemium (Free for up to 100 build configurations and 3 agents)
• Supported OS: Windows, Linux, macOS

Top Features of TeamCity for Scaling CI/CD

Here are some of the most notable features that make TeamCity stand out:

• Smart CI/CD Pipelines: Define flexible build chains with dependencies, triggers, parallel test execution, and conditional logic.
• Kotlin DSL Configuration: Allows you to define your entire CI/CD configuration as code, providing version control, reusability, and excellent tooling support (like auto-completion) within IDEs.
• Commit Safety Nets: Use pre-tested commits and personal builds to avoid breaking main branches.
• IDE Integration: View build results and test reports directly in IntelliJ, Visual Studio, or Eclipse.
• Advanced Build Triggers: Automate builds based on events like code changes, schedules, or custom criteria, ensuring timely execution.
• Cloud Integration: Deploy TeamCity on cloud platforms like LambdaTest, AWS, Azure, and GCP, dynamically scaling resources for faster builds.
• Test Intelligence: Detect flaky tests, auto-retry failures, and run only relevant tests to improve speed and reliability.
• Scalable Build Agents: Run multiple agents across OSs, VMs, or containers for faster builds.
• VCS Support: Integrates with Git, Mercurial, SVN, Perforce, and more. Supports PR workflows, branch filters, and commit tracking.
• Artifact Management: Store, manage, and clean up build artifacts with built-in tools and external storage support.
• Powerful Reporting: Generate detailed reports on builds, tests, and code quality, visualizing trends to drive informed decisions and improve quality.

How to Download and Set Up TeamCity

Step 1: Download the Server

Start by visiting the TeamCity Download Page. Choose the appropriate version for your system:

• Windows: Installer or ZIP distribution
• Linux/macOS: TAR.GZ package
• Docker: Official images available on Docker Hub

Step 2: Install and Launch

Unpack the archive or run the installer. Once complete, launch the TeamCity server. By default, it runs on http://localhost:8111.

The first time you launch the server, TeamCity will walk you through a simple setup wizard where you’ll:

• Choose a database (HSQLDB for testing or PostgreSQL/MySQL for production)
• Create the first administrator account
• Connect to your version control system

Step 3: Set Up the Build Agent

Build agents run the actual jobs defined in your pipelines. You can install them on the same machine or across different environments. The agent installer is available from the TeamCity web UI, under Agents > Install Build Agent.

Each agent can be configured with its own capabilities, such as installed SDKs, operating system details, or Docker support.

Step 4: Create Your First Project

Once your server and at least one agent are online:

1. Connect your GitHub, GitLab, or Bitbucket repository.

2. TeamCity will automatically detect build steps (e.g., Maven, Gradle, npm).

3. You can customize the steps or use the suggested configuration.

Step 5: Deployment Options

You can run TeamCity in whatever environment fits your team:

• On-Premises: Install and manage your own infrastructure. Useful for regulated environments or teams with custom requirements.
• Cloud Agents: Spin up build agents dynamically on AWS, Azure, or GCP.
• Docker-Based: Run TeamCity inside containers to isolate builds and simplify updates.
• Kubernetes-Friendly: Use Helm charts to manage TeamCity installations on Kubernetes clusters.

(Optional) Step 6: Connect to LambdaTest

Add LambdaTest commands in your build steps to bring speed, scalability, and AI-native intelligence to your testing process.

• Run tests on 3000+ real browsers, devices, and OS combinations.
• Trigger Selenium, Cypress, Playwright, and Appium tests from TeamCity.
• Speed up execution with HyperExecute (LambdaTest next-gen test execution cloud).
• View reports with logs, videos, and screenshots.
• Detect flaky tests and get AI-native insights.
• Debug faster with browser logs and performance data.

Integrating TeamCity with LambdaTest ensures higher test coverage, faster feedback cycles, and more reliable releases, directly from your TeamCity environment.

Step 7: Explore TeamCity Plugins and Extensions

• Extend functionality with plugins for Jira, YouTrack, Slack, FOSSA, and more.
• Use plugins for license compliance, security scanning, and code quality checks.
• Integrate with build tools like NUKE, MSBuild, Ant, Gradle, and custom CLI runners.

TeamCity Pricing Models: Flexible for Teams of All Sizes

• Scalability for large teams

What Users Appreciate:

• Flexible configuration options using Kotlin-based DSL and templates
• Broad integration ecosystem, supporting Git, Docker, AWS, Azure, Selenium, and more
• Responsive support and documentation, especially for enterprise clients

Areas for Improvement:

• Kotlin DSL has a learning curve for teams unfamiliar with the language
• The plugin ecosystem is smaller than Jenkins or GitHub Actions, requiring more manual setup in certain cases
• More expensive than other industry alternatives like Jenkins

TeamCity vs Other CI/CD Alternative Tools

Let’s compare TeamCity with a few popular CI/CD alternatives:

Verdict: Choose TeamCity for developer-focused CI/CD with powerful defaults, strong IDE support, and minimal plugin maintenance. Jenkins may suit open-source enthusiasts, while GitLab CI and CircleCI offer good cloud-native options for Git-centric teams.

How Engineering Teams Achieve 40,000+ Daily Builds with TeamCity

Top engineering teams use TeamCity to scale CI/CD, speed up builds, and bring stability to complex pipelines across gaming, developer tools, and enterprise systems:
