Nx vs Qbs

Nx is a build system for JavaScript and TypeScript monorepos, with plugins that can extend its work to other languages. It builds project and task graphs, follows task dependencies, and runs work in parallel where possible. Nx Core provides local caching; Nx Cloud adds a remote cache shared by teams and CI, and can distribute tasks across Nx Agents according to CPU and memory use. Plugins can infer tasks, generate or alter code, update dependencies, and provide executors. Documented integrations include Angular, React, Vue, Node.js, Java, .NET, Vite, Webpack, Rspack, Jest, Cypress, and Playwright. Nx also provides CI workflow setup for GitHub, CircleCI, GitLab, Azure Pipelines, Jenkins, and Bitbucket Pipelines. Nx Cloud describes trusted-branch cache writes, artifact traceability, and invalidation of artifacts made with revoked tokens. API communications are encrypted in transit, and task artifacts can be encrypted end to end before remote caching. Hobby is free forever, with monthly credits, contributor and CI-connection limits; Team is $29/month, with additional listed charges for usage, contributors, and connections.

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.
