Choose your architecture

Start with the architecture that fits your project needs

Standard Architecture

Recommended

Perfect for most applications with clean separation of concerns

app/ - Application layer (routers, dependencies)
domain/ - Business logic and entities
infrastructure/ - Database, external services
modules/ - Feature-based organization

DDD Architecture

Enterprise

Domain-Driven Design for complex business domains

domain/ - Entities, value objects, aggregates
application/ - Use cases and services
infrastructure/ - Repositories and adapters
presentation/ - API endpoints and schemas

Powerful CLI Tools

Comprehensive command-line interface for all your development needs

Get started in 5 steps

From installation to production-ready application

1

Create Workspace

NPM package sets up workspace & installs Python core

npx rapidkit my-workspace
2

Activate Environment

Enter the Python environment

cd my-workspace && source $(poetry env info --path)/bin/activate
3

Create Project

Interactive project creation (works in/out of workspace)

npx rapidkit create project
4

Add Modules

Install modules with auto-integration

cd my-api && npx rapidkit add module free/cache/redis
5

Start Development

Bridge to Python dev server (direct works inside workspace)

npx rapidkit dev
