Continuous Feedback

Receive fast and continuous feedback with Workflows job orchestration.


Greater Control

Take control of your environment with first class support for the Docker platform, language inclusiveness and more.

What's new in CircleCI 2.0?

Language Inclusive

Supports any language that builds on Linux, including C++, Javascript, .NET, PHP, Python, and Ruby. You're free to use any toolchain, framework, or version you need.

Custom Environments

Full control of your build environment means you won't have to worry about it being outdated or updated without your knowledge. Run CI/CD without limits or bounds.

Flexible Resource Allocation

We realize continuous integration is not one-size-fits-all. With CircleCI 2.0 you can easily configure your resources (compute/memory) to best fit your team's needs for specific builds.

Local Builds

Helps you validate YML files and easily update your configuration to the latest version. Running jobs in your local environment ensures faster remediation of issues.

Powerful Caching

Speed up your builds even more with our expanded caching options, including images, source code, dependencies, and custom caches. Implement granular caching strategies with control over cache save and restore points throughout your jobs for optimal performance.

Added Security

Run builds on machines in isolation for greater security. As always, when required to run or test your source code, CircleCI uses SSH and/or HTTPS encryption.

First Class Support for the Docker Platform

  • Docker layer caching ensures fast, consistent, and accurate build results.
  • Ability to push/pull public and private images.
  • Support for several public registries including Docker Hub, Google Container Registry, CoreOS Quay, and Amazon ECR.
  • Docker Compose support helps define and run multi-container Docker applications.
  • View runtime metrics with local builds (CPU, memory and others) so you can adjust box-type options (Docker, Docker Engine, virtual machine, etc) to ensure maximum efficiency in build times.

“We successfully migrated both repos and see phenomenal performance improvements, especially when we leverage caching! Our project's build times went from roughly 2:30 minutes to 1:30 (without cache) and 0:50 (with cache).”
