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
Unleash
- The Pay-As-You-Go plan is priced per seat, which can get costly for larger teams.
- Self-hosted Enterprise requires a minimum of 5 seats and an annual contract.
- Additional API traffic beyond the included quota is billed per million requests.
- Advanced SLAs and dedicated customer success are reserved for the custom Enterprise tier.
