Braintrust
- The free Starter tier includes only $10 of monthly model credits, 1 GB of processed data, and 10,000 scores before overage charges of $4 per GB and $2.50 per 1,000 scores apply, as of August 2026.
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
