Our review
Pros
  • Hosted Linux, macOS, and Windows agents plus self-hosted agents
  • Dynamic pipelines, parallel execution, caching, and test optimization
  • GitHub, GitLab, Bitbucket, cloud, Kubernetes, and observability integrations
  • YAML and visual workflow configuration support both code-first and visual setup
  • Parallel jobs, caching, artifacts, and test reporting support faster feedback
  • Self-hosted agents and Community Edition support customer-managed infrastructure
Cons
  • Pro pricing starts at $30 per active user per month
  • The Pro plan includes 10 agents, limiting included parallel capacity
  • Hosted-agent compute is billed separately by vCPU minute
  • Usage-based compute pricing makes monthly costs dependent on consumption
  • The managed plan has 20 concurrent jobs by default
  • Advanced workflows may require managing YAML, visual configuration, or self-hosted agents
