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

DeepSource

  • Open Source plan caps at 1,000 reviewed pull requests and 1,000 formatting runs per month.
  • AI Review beyond the included credit is billed per 10K lines of code, which can add unpredictable cost.
  • Self-hosted deployment and BYOK AI are Enterprise-only features.
  • Enterprise pricing is not published and requires contacting sales.
