main entity: Which framework is faster: FastAPI or Gin?
  type: Question
  accepted answer: Answer
    text: Gin is significantly faster. Benchmarks show Gin handles 40,000-60,000 requests/second versus FastAPI's 8,000-12,000 req/s—a 4-6x difference. This is because Go compiles to native machine code with minimal runtime overhead, while Python requires interpretation. However, FastAPI is still sufficiently fast for most real-world applications (>10k req/s is enterprise-grade).
    language: en-US
main entity: Does FastAPI automatically generate API documentation?
  type: Question
  accepted answer: Answer
    text: Yes, FastAPI automatically generates OpenAPI 3.0 (Swagger) documentation by visiting /docs or /redoc endpoints. This happens without any additional code due to FastAPI's use of Pydantic models and Python type hints. Gin has no built-in documentation—you must manually implement OpenAPI generation using third-party libraries like swag.
    language: en-US
main entity: Can I deploy Gin and FastAPI the same way?
  type: Question
  accepted answer: Answer
    text: No. Gin compiles to a single binary executable that runs standalone (ideal for Docker/Kubernetes). FastAPI requires a Python ASGI server like Uvicorn or Hypercorn to run in production. Gin's approach is simpler for containerization and has no runtime dependencies, while FastAPI requires the Python runtime environment in your container.
    language: en-US
main entity: Which is better for learning web development?
  type: Question
  accepted answer: Answer
    text: FastAPI is better for learning because it requires less boilerplate code, provides built-in validation, and generates documentation automatically. Gin forces you to write validation logic manually, which teaches more fundamentals but requires more code. If you're new to backend development, FastAPI gets you to a working API faster.
    language: en-US
main entity: Should I use FastAPI or Gin for a production microservice?
  type: Question
  accepted answer: Answer
    text: For a high-traffic microservice expecting 10k+ req/s, Gin is superior due to 4-6x better throughput and lower memory footprint. For internal microservices with moderate traffic (<5k req/s), rapid development needs, or a Python-heavy stack, FastAPI is pragmatic. Consider Go if scale and performance are critical; choose Python if developer velocity and rapid iteration matter most.
