| description.long | An open-source build and test system designed to efficiently compile and test projects written in multiple programming languages while supporting builds for different target platforms. It uses intelligent caching and parallel execution to speed up builds and scales to handle large codebases across multiple repositories. | A platform that replaces shell scripts and YAML configurations with code-based pipelines. Runs identically on local machines and in CI/cloud environments, with built-in observability through OpenTelemetry traces and automatic content-addressed caching. |
