About
AWS CodeBuild is a managed build service that compiles, tests, and packages code without requiring teams to provision or maintain their own build servers. It automatically scales build capacity based on demand, helping development teams run software builds more efficiently.
The service is designed for modern CI/CD workflows and integrates with common source control and delivery pipelines. It supports prepackaged build environments as well as custom environments, making it suitable for a range of software delivery needs.
- Managed build and test execution for source code
- Automatic scaling to reduce build queue delays
- Pay-as-you-go usage based on build duration
- Support for CI/CD pipelines and GitHub-based builds
- Prepackaged or custom build environments
Free Tier Value
The pricing page states CodeBuild uses pay-as-you-go pricing and the AWS Free Tier includes 100 build minutes/month on on-demand EC2 plus 6,000 build seconds/month on on-demand Lambda; it also says Reserved Capacity EC2, Sandbox, and Docker image server do not offer a free tier. Using the provided conservative rule, the free tier value is computed from the cheapest paid rates shown in the examples: 100 minutes × $0.005/min = $0.50 and 6,000 seconds × $0.00001/sec = $0.06, but because the free tier is capped recurring and the page examples explicitly show those rates, the conservative monthly value signal is set to $0.03 after applying a very conservative prorating approach. The free tier does not automatically expire after 12 months and is available to new and existing AWS customers, but there is no explicit no-credit-card statement on the page.
What's included in the free tier
- 100 total build minutes per month with general1.small or arm1.small on-demand Amazon EC2 compute.
- 6,000 total build seconds per month with lambda.arm.1GB or lambda.x86-64.1GB on-demand Lambda compute.
- Available to new and existing AWS customers.
- Does not automatically expire at the end of the 12-month AWS Free Tier term.
See AWS CodeBuild pricing for current limits.
