The Verdict
CircleCI is built for development teams and open source projects, with a focus on ci-cd-pipelines and docker-support. Datadog targets devops teams and sre teams and leads with infrastructure-monitoring and apm.
Both tools come in at similar price points ($15/mo for CircleCI, $15/mo for Datadog), so pricing won't make the decision for you.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
This is a genuinely close comparison. If you can, sign up for both free trials (where available) and run a one-week test with your actual team tasks before deciding.
