AWS CodeBuild vs Qbs

AWS CodeBuild is a paid, cloud-hosted continuous integration service for compiling, testing, and packaging code from build scripts. It provisions and scales build capacity automatically, so projects do not require users to manage build servers. Preconfigured environments cover Java, Python, Node.js, Ruby, Go, Android, .NET Core for Linux, and Docker; teams can also supply Docker-based environments. A YAML build specification defines commands for each build phase and other settings. Builds can start from CodeCommit, GitHub, GitHub Enterprise, Bitbucket, Amazon S3, or CodePipeline, and can work with Jenkins. Artifacts can be stored in S3 or sent to an artifact repository. IAM provides access controls, while KMS keys encrypt artifacts. Build timing, status, commit ID, metrics, and logs are available through the service and CloudWatch, with SNS event notifications. A free plan provides stated monthly allowances; paid usage starts at 0.01 USD and can add charges for data transfer and related AWS services.

Qbs is a build automation tool for managing software projects across multiple platforms. Projects can use it regardless of programming language, toolkit, or libraries, and its declarative model lets them describe build tasks and dependencies without setting the build order. The manual lists correct, fast incremental builds and an extensible architecture among its features. Qbs documents built-in support for Windows, Linux, macOS, Android, iOS, tvOS, watchOS, QNX, and FreeBSD, plus cross-compilation. It can be used with Qt Creator and Visual Studio Code through the Qbs session feature, and it can generate Clang compilation databases. Project generation for Visual Studio, IAR Embedded Workbench, and Keil uVision is available but described as experimental. Binaries are available for Windows, macOS, Linux, and FreeBSD, or Qbs can be built locally from source. The Qbs plan costs nothing. Its library and tools are available under commercial licenses, LGPL version 3, and GPL version 2. The Makefile generator will not create a Makefile if the source, build, or install root directory contains spaces; other UNIX-like systems may work but are not regularly tested or officially supported.
