Per-second billing¶
Use compute credits to run as many parallel tasks as you want and pay only for CPU time used by these tasks. Another approach is to bring your own infrastructure and pay directly to your cloud provider within your current billing.
No concurrency limit. No queues¶
Cirrus CI leverages elasticity of the modern clouds to always have available resources to process your builds. Engineers should never wait for builds to start.
Bring Your Own Infrastructure¶
Cirrus CI supports bringing your own infrastructure (BYO) for full control over security and for easy integration with your current workflow.
Flexible runtime environment¶
Cirrus CI allows you to use any Unix or Windows VMs, any Docker containers, any amount of CPUs, optional SSDs and GPUs.
Basic but very powerful configuration format¶
Learn more about how to configure tasks here. Configure things like:
- Matrix Builds
- Dependencies between tasks
