ignyx 1.1.0

Rust-powered Python web framework — 10x faster than FastAPI

Ignite your API. Built in Rust, runs in Python.

Description

Ignyx is a next-generation Python web framework engineered for maximum throughput, utilizing a Rust-powered HTTP core built on Hyper and Tokio. It provides a familiar, FastAPI-like decorator syntax, allowing developers to build high-performance APIs with zero learning curve. In honest benchmarks, Ignyx operates 8-9x faster than standard Python async frameworks. It integrates seamlessly with the modern Python ecosystem, featuring full async/await capability, Pydantic v2 validation, WebSockets, and dependency injection.

Features

• Blazing fast (8-9x FastAPI)
• Owns full HTTP pipeline — no ASGI overhead
• Native async/await support
• Pydantic v2 validation
• Dependency injection (Depends pattern)
• WebSocket support
• Modular routing with Router + prefix
• py.typed for full IDE autocompletion

Benchmark

Apple M2, wrk -t4 -c100 -d10s

Endpoint	Ignyx	FastAPI	Speedup
/plaintext	53,886 req/s	6,193 req/s	🔥 8.70x
/users/{id}	48,988 req/s	5,597 req/s	🔥 8.75x
/users (POST JSON)	44,178 req/s	5,200 req/s	🔥 8.49x

Note: FastAPI tested with Uvicorn single worker — standard config.

Installation

pip install ignyx

Or with uv:

uv add ignyx

Quickstart

from ignyx import Ignyx

app = Ignyx()

@app.get("/")
async def root(request):
    return {"message": "Hello from Ignyx!"}

if __name__ == "__main__":
    app.run(host="0.0.0.0", port=8000)

Feature Examples

Pydantic Validation

from ignyx import Ignyx
from pydantic import BaseModel, ValidationError

app = Ignyx()

class User(BaseModel):
    name: str
    age: int

@app.post("/users")
async def create_user(request):
    try:
        user = User(**request.json())
        return {"status": "success", "data": user.model_dump()}
    except ValidationError as e:
        return {"error": e.errors()}, 400

Path + Query Parameters

from ignyx import Ignyx

app = Ignyx()

@app.get("/users/{id}")
async def get_user(request, id: int):
    format_type = request.query.get("format", "json")
    return {"id": id, "format": format_type}

Dependency Injection

from ignyx import Ignyx, Depends

app = Ignyx()

def get_token(request):
    auth_header = request.headers.get("Authorization")
    if auth_header and auth_header.startswith("Bearer "):
        return auth_header.split(" ")[1]
    return None

@app.get("/secure")
async def secure_route(request, token=Depends(get_token)):
    if not token:
        return {"error": "Unauthorized"}, 401
    return {"message": "Access granted", "token": token}

Middleware

from ignyx import Ignyx

app = Ignyx()

@app.middleware
async def cors_middleware(request, call_next):
    response = await call_next(request)
    response.headers["Access-Control-Allow-Origin"] = "*"
    return response

WebSockets

from ignyx import Ignyx

app = Ignyx()

@app.websocket("/echo")
async def echo_server(ws):
    await ws.accept()
    while True:
        data = await ws.receive_text()
        if data == "close":
            break
        await ws.send_text(f"Echo: {data}")

Modular Routing

from ignyx import Ignyx, Router

app = Ignyx()
api_router = Router(prefix="/api/v1")

@api_router.get("/status")
async def status(request):
    return {"status": "operational"}

app.include_router(api_router)

Comparison vs FastAPI

Feature	Ignyx	FastAPI
Pydantic v2 validation	✅	✅
Async/Await	✅	✅
Dependency Injection	✅	✅
WebSockets	✅	✅
Modular Routers	✅	✅
Performance (req/s)	~50k	~6k
ASGI overhead	❌ None	✅ Yes
TestClient	⚠️ WIP	✅
Static file serving	⚠️ WIP	✅
Lifespan events	⚠️ WIP	✅
Exception handlers	✅	✅

Current Limitations

• No TestClient yet (use httpx directly against a running server for now)
• No static file serving via app.mount() yet
• No lifespan events (startup/shutdown) yet
• Hot reloading not yet implemented
• OpenAPI schema is basic (no Pydantic response schemas yet)

These are all on the roadmap and will ship in upcoming releases.

Deployment Note

Ignyx manages its own Tokio runtime. No Uvicorn or Gunicorn needed. Just python app.py.
