Realworld

RealWorld is an open-source project that provides a standardized blueprint for building functionally identical applications across diverse programming languages and frameworks. By establishing a contract-first API specification and a shared data model, it enables developers to create decoupled frontend and backend components that are fully interoperable.

The project distinguishes itself through a comprehensive catalog of over 100 reference implementations, allowing for direct comparison of architectural patterns and syntax across different technology stacks. To ensure consistency, every implementation is validated against an automated integration test suite that enforces strict compliance with the shared API contract. This approach allows any frontend to interface with any backend, facilitating full-stack prototyping and cross-framework benchmarking.

Beyond the core API requirements, the project includes shared design system assets and a consistent CSS theme to maintain a unified visual experience across all implementations. Detailed documentation and guides are available to assist developers in creating new, spec-compliant applications within this ecosystem.

Features

Cross-Framework Implementations - Over 100 implementations have been created using various languages, libraries, and frameworks. Explore them on [**CodebaseShow**](https://codebase.show/projects/realworld). ## Spec-compliant backends These backends pass
Reference Implementations - A comprehensive collection of functionally identical applications built across diverse programming languages to demonstrate framework-specific patterns and architectural trade-offs.
Technical Skill Acquisition Platforms - Learning new development stacks by studying consistent, real-world application patterns implemented across a wide variety of modern programming languages.
Implementation Guides - [**Create a new implementation >>>**](https://docs.realworld.show/implementation-creation/introduction) Or you can [view upcoming implementations (WIPs)](https://github.com/realworld-apps/realworld/discussions/categories
Spec-compliant Backends - These backends pass the full [API spec test suite](specs/api/): - [**Nitro + Prisma + Zod**](https://github.com/realworld-apps/nitro-prisma-zod-realworld-example-app) — TypeScript - [**Django Ninja**](https://github.com/
Application Blueprints - A common architectural template that enables the seamless swapping of frontend and backend components through strict adherence to a shared contract.
Specification-Driven Architectures - Enables developers to build functionally identical applications using any programming language or framework by following a common specification.
Decoupled Architectures - Separates client and server concerns to allow any frontend implementation to interface with any compliant backend service.
Interoperability Demonstrations - You can combine any frontend with any backend, because **they all adhere to the same API spec** While most "todo" demos provide an excellent cursory glance at a framework's capabilities, they typically don't convey the k
Cross-Platform Specification Suites - A standardized set of API requirements and data models designed to ensure interoperability between heterogeneous frontend and backend technology stacks.
Architecture Prototyping Frameworks - Evaluating how different frontend and backend technologies interoperate by swapping components that share a common, standardized data interface.
Contract-First Specifications - Standardises communication between decoupled frontends and backends by enforcing a strict, shared schema for all data exchange.
Integration Test Suites - Validates backend compliance against the shared API specification to ensure interoperability across diverse technology stacks.
API Specification Compliance Tools - Validating that a backend implementation correctly adheres to a standardized API contract through automated testing and integration suites.
Compliance Benchmarks - A shared testing protocol that validates the compliance of independent software implementations against a unified set of functional and interface requirements.
