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; WarpBuild per-minute pricing requires tracking usage to estimate monthly costs

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

WarpBuild

  • Per-minute pricing requires tracking usage to estimate monthly costs
  • Large configuration runners (32 vCPU) expensive at $0.064/min
  • macOS M4 Pro 12-core at $0.16/min is highest-cost option
  • BYOC option requires cloud setup by customer
