APiGen CodeGen

The most powerful code generation engine for APIs - Transform SQL schemas and OpenAPI specs into production-ready, multi-language API projects with 100+ enterprise features in seconds.

Overview

Building modern APIs from scratch is time-consuming and error-prone:

• ❌ Weeks of manual coding (entities, repositories, services, controllers, DTOs, tests)
• ❌ Repetitive boilerplate (same patterns for every entity)
• ❌ Framework decisions paralysis (Spring? FastAPI? NestJS? Laravel?)
• ❌ Infrastructure setup (Docker, K8s, CI/CD, monitoring)
• ❌ Enterprise features integration (auth, caching, messaging, observability)
• ❌ Multi-language team challenges (Java backend + TypeScript frontend + Python ML)

APiGen CodeGen solves this by:

• ✅ Generating complete projects in seconds (entities → tests → deployment, fully functional)
• ✅ Supporting 11+ languages (Java, Kotlin, Python, TypeScript, Go, Rust, PHP, C#, React)
• ✅ Including 100+ enterprise features (JWT, OAuth2, GraphQL, gRPC, Kafka, observability)
• ✅ Following best practices (SOLID, DRY, clean architecture, 12-factor app)
• ✅ Production-ready output (Docker, K8s, Terraform, monitoring, logging)
• ✅ Extensible & customizable (custom generators, templates, features)
