Hof is a tool that weaves together data models, code generation, and task engine with CUE. Automate repetitive setup, code, changes, and workflows using your tools. Hof is technology agnostic.
| Core Features | |
|---|---|
| code generation | data + template = _ (anything) ...any file, technology agnostic |
| app blueprints | consistently bootstrap apps, code, config, and other files |
| data model | define and manage data models, evolve code with them |
| task engine | extensible task and workflow DAG engine |
| modules | composable dependencies for blueprints, models, and generators |
hof is a CLI tool you will add to your workflows.
It is technology agnostic, captures common patterns and boilerplate,
has modules that span technologies, and continues to work as your application evolves.
- data model management so you can checkpoint, diff, and calculate migrations
- code generation to scaffold consistent code and boilerplate across the stack
- diff3 to support custom code, data model updates, and code regeneration
- modular and composable code generators with dependency management
hof uses CUE extensively to power the DX and implementation.

The getting-started section will take you on a tour of hof. The first-example section shows you how to build and use a generator.
