CircleCI vs Zephyr Scale
The short version
- Only CircleCI has a free tier, so it costs nothing to try first.
- Each has a real cost: CircleCI the free plan covers 6,000 build minutes and 5 active users a month; Zephyr Scale split across separate Essential and Advanced editions plus a distinct Zephyr Enterprise on-premises product, so buyers must pick the right SKU before pricing applies

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
Zephyr Scale
- Split across separate Essential and Advanced editions plus a distinct Zephyr Enterprise on-premises product, so buyers must pick the right SKU before pricing applies
