Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

CircleCI

The free plan covers 6,000 build minutes and 5 active users a month
Active users are billed at $15 each beyond the included five, and an active user is anyone who commits to a project
Everything runs on credits, so compute, Docker layer caching at 200 credits a job and IP ranges at 450 credits per GB all draw from the same pool
Network and storage overage costs 420 credits per GB
Free credits expire monthly with no rollover, and paid credits expire after a year
Scale is annual billing only

Moonrepo

Smaller community compared to established build systems like Bazel
Limited integrations with enterprise CI/CD platforms
Documentation gaps in some advanced use cases
No commercial support option for organizations requiring guaranteed SLAs
