GitHub Actions macOS runner ($0.048/min) costs exactly 10x more than Ubuntu ($0.006/min). One workflow switch can save $1,000+/year.
GitHub Actions Linux went from $0.008 to $0.006/min on January 1, 2026. Windows dropped from $0.016 to $0.010. macOS from $0.080 to $0.048.
CodeBuild Lambda compute bills per second. A 30-second build on EC2 bills 1 full minute ($0.005). On Lambda it bills 30 seconds ($0.0003).
GitLab CI charges $0.010/min for ALL runners — Linux, Windows, and macOS. No multipliers. For macOS-heavy teams it is up to 5x cheaper than GitHub.
Open source projects on CircleCI get 400,000 free credits/month — 13x more than standard. That equals 40,000 minutes of Linux builds.
ARM Graviton2 is 20% cheaper on Lambda and 32% cheaper on CodeBuild than x86. Most Linux workloads require zero code changes.
Every developer deserves accurate pricing data without paywalls, email walls, or credit cards. These tools are free forever — that is the whole point.
