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

CLion

  • Specific subscription pricing not listed on product page
  • Requires reference to separate store page for tier details
  • AI credits needed for integrated AI features
  • No mention of free trial for commercial use
