astraapi 0.2.1

AstraAPI framework, high performance, easy to learn, fast to code, ready for production

AstraAPI

FastAPI-compatible. C++ core. Built-in workers. No gunicorn needed.

---

AstraAPI is a drop-in replacement for FastAPI with a compiled C++20 core. Same decorators. Same Pydantic models. Same OpenAPI docs. But 5-10x faster — no external server required.

from astraapi import AstraAPI

app = AstraAPI()

@app.get("/")
def hello():
    return {"message": "Hello World"}

if __name__ == "__main__":
    app.run(port=8000, workers=4)

Output:

C++ HTTP server running on http://127.0.0.1:8000
Press Ctrl+C to stop

Why AstraAPI?

	FastAPI + Uvicorn	AstraAPI
HTTP parser	httptools (Python)	llhttp (C++, Node.js)
JSON	orjson	yyjson + SIMD serializer
Workers	gunicorn/uvicorn	Built-in fork/spawn
Keep-alive	Per-connection timers	Batch sweep
Compression	zlib	libdeflate (2-3x faster)
Throughput	~45k req/s	~236k req/s

Install

pip install astraapi

Python 3.14+

Quick Start

python -m astraapi --help

Or write a file:

from astraapi import AstraAPI
from pydantic import BaseModel

app = AstraAPI()

class Item(BaseModel):
    name: str
    price: float

@app.get("/items/{item_id}")
def read_item(item_id: int, q: str | None = None):
    return {"item_id": item_id, "q": q}

@app.post("/items/")
def create_item(item: Item):
    return item

if __name__ == "__main__":
    app.run(port=8000, workers=4)

Features

• 100% FastAPI compatible — same @app.get, Depends, BaseModel, Query, Path, File, UploadFile, WebSocket, BackgroundTasks
• Built-in multi-worker server — SO_REUSEPORT, CPU affinity, auto-restart. No gunicorn.
• C++ HTTP core — llhttp parser, radix trie router, yyjson, SIMD string escape, ryu float formatting
• Zero-copy transport — direct send() for small responses, writev() for WebSockets
• Native middleware — CORS, GZip (libdeflate), TrustedHost, HTTPSRedirect, RateLimiting
• Real TestClient — starts actual C++ HTTP server on ephemeral port
• Hot reload — app.run(reload=True) watches files via watchfiles
