CircleCI
CircleCI orchestrates cloud and private runners through configuration, workflows, caches, artifacts, matrices, and reusable Orbs.
Why use it
Client tools and backends test in parallel while performance insights identify slow jobs.
Where it fits
Find engines, frameworks, code libraries, version control, and production automation.
What to check
The service is proprietary and quotas change by plan; review Orbs, context secrets, and third-party images.
