StackT

StackT is a cross-platform software framework and runtime designed to help developers define, assemble, and deploy technology stacks for modern applications. It uses a declarative configuration model in a dedicated StackT Script to describe components such as databases, services, queues, and front-end layers, and to specify their relationships, deployment targets, and runtime requirements. Stacks are composed of modular units called bricks, which may be supplied by StackT or by third-party plugins.

The core components of StackT include a runtime engine, a command-line interface, and a plugin system. The runtime resolves dependencies, provisions resources, and orchestrates deployment across environments, while the CLI provides commands such as stack build, stack test, and stack deploy. The plugin ecosystem enables integration with cloud providers, container platforms, and observability tools, as well as custom extensions. StackT supports containerized deployment via Docker and orchestration through Kubernetes, and it can operate locally, on private clouds, or on public cloud platforms.

Key concepts in StackT involve reproducibility and modularity. Stacks are versioned and stored as definable artifacts, allowing consistent recreation of environments across development, testing, and production. The framework includes built-in testing and staging capabilities to validate changes before release. Documentation and community resources exist to guide users through modeling architectures, writing plugins, and integrating with CI pipelines.

StackT has a modest user base among cloud-native developers, with praise for its reproducibility and extensiblePlugin architecture, and criticism related to its learning curve and initial setup complexity.
