Pre-release
This release is a pre-release and may not be stable for production use.
The fastest Python web framework — built on Django
Rust-powered HTTP, msgspec serialization, full type validation —
with the Django ORM, Django Admin, and every Django package you already use.
Documentation · Quick Start · Features · Benchmarks · Video Tutorial · Discord
Django-Bolt is the fastest Python web framework: 300k+ requests/second on a single 12-core desktop (8 processes, C=100, loopback), ahead of FastAPI and Robyn, and even of Bun-based JavaScript frameworks (Elysia, Hono) on JSON payloads. It is a fully typed API framework for Django. It serves your endpoints from a Rust HTTP server (Actix Web + Tokio), bridges to your Python handlers with PyO3, and serializes with msgspec — while everything you love about Django (ORM, Admin, auth, middleware, signals, third-party apps) keeps working out of the box.
Think Django REST Framework or Django Ninja, with a Rust engine underneath and no gunicorn or uvicorn required.
from django_bolt import BoltAPI
api = BoltAPI()
@api.get("/hello/{name}")
async def hello(name: str):
return {"message": f"Hello, {name}!"}
python manage.py runbolt --dev
✨ Why Django-Bolt?
| ⚡ Rust speed, Python ergonomics | HTTP parsing, routing, auth, guards, CORS, rate limiting, and compression run in Rust without touching the GIL. Your handlers stay plain Python. |
| 🐍 100% Django | Use your existing models, settings.py, INSTALLED_APPS, Django Admin, middleware, and signals. Migrate one endpoint at a time from DRF. |
| 🧷 Fully typed | Type hints drive path/query/header/cookie/form/body extraction and validation. msgspec.Struct and Bolt Serializer return types are validated on the way out. |
| 🚀 Deploy directly | runbolt is the production server: multi-process with SO_REUSEPORT, worker recycling, graceful shutdown, static & media serving. |
| 📚 Batteries included | OpenAPI docs (Swagger, ReDoc, Scalar, RapiDoc, Stoplight), JWT/API-key auth, guards, pagination, ViewSets, WebSockets, SSE, streaming, testing client, MCP servers. |
🚀 Quick Start
1. Install
pip install django-bolt # or: uv add django-bolt
2. Add to INSTALLED_APPS
# myproject/settings.py
INSTALLED_APPS = [
...,
"django_bolt",
]
3. Write your first endpoint
Create an api.py next to your settings.py (or inside any Django app — Bolt autodiscovers them all):
# myproject/api.py
import msgspec
from django.contrib.auth import get_user_model
from django_bolt import BoltAPI
User = get_user_model()
api = BoltAPI()
class UserSchema(msgspec.Struct):
id: int
username: str
@api.get("/users/{user_id}")
async def get_user(user_id: int) -> UserSchema: # response is type-validated
user = await User.objects.aget(id=user_id) # Django ORM, no extra setup
return {"id": user.id, "username": user.username}
4. Run
python manage.py runbolt --dev # auto-reload for development
python manage.py runbolt --processes 4 # production: multi-process, no gunicorn/uvicorn
Your API is live at http://localhost:8000/users/1 and interactive docs at http://localhost:8000/docs.
📖 Next: the Quick Start guide → Deployment → Topic guides.
🧭 A tour of the API
Request validation with type hints
import msgspec
from typing import Annotated
from django_bolt import BoltAPI
from django_bolt.param_functions import Header
api = BoltAPI()
class CreateUser(msgspec.Struct):
username: str
email: str
@api.post("/users", status_code=201)
async def create_user(
user: CreateUser, # JSON body → validated struct
api_key: Annotated[str, Header("x-api-key")], # header
page: int = 1, # query param with default
):
return {"username": user.username, "page": page}
Authentication & guards (evaluated in Rust)
from django_bolt.auth import JWTAuthentication, IsAuthenticated, Requires
IsStaff = Requires("is_staff", True)
@api.get("/admin/stats", auth=[JWTAuthentication()], guards=[IsAuthenticated(), IsStaff])
async def admin_stats(request):
return {"user_id": request.user.id}
JWT signature checks, expiry, API-key lookup, and guard evaluation all happen before the GIL is ever taken.
Serializers & ModelViewSet
from django_bolt import ModelViewSet, PageNumberPagination
from django_bolt.serializers import Serializer
from myapp.models import Article
class ArticleSchema(Serializer):
id: int
title: str
content: str
class Config:
field_sets = {"list": ["id", "title"]}
@api.viewset("/articles")
class ArticleViewSet(ModelViewSet):
queryset = Article.objects.all()
serializer_class = ArticleSchema
pagination_class = PageNumberPagination
One Serializer class, many projections — no more UserListSerializer / UserDetailSerializer / UserAdminSerializer sprawl.
WebSockets & Server-Sent Events
from django_bolt import WebSocket, StreamingResponse
@api.websocket("/ws/echo")
async def echo(websocket: WebSocket):
await websocket.accept()
async for message in websocket.iter_text():
await websocket.send_text(f"Echo: {message}")
@api.get("/events")
async def events():
async def stream():
for i in range(10):
yield f"data: tick {i}\n\n"
return StreamingResponse(stream(), media_type="text/event-stream")
MCP servers for LLM clients
from bolt_mcp import MCP # pip install "django-bolt[mcp]"
mcp = MCP("my-server")
@mcp.tool
async def add(a: int, b: int) -> dict:
return {"sum": a + b}
api.mount_mcp(mcp)
Expose tools, resources, and prompts over MCP Streamable HTTP, backed by the official Rust SDK.
Middleware: CORS, rate limiting, compression
from django_bolt.middleware import cors, rate_limit
@api.get("/public")
@cors(origins=["https://example.com"])
@rate_limit(rps=100, burst=200)
async def public():
return {"ok": True}
Django middleware (sessions, messages, CSRF, your own) is supported too.

🏗️ How it works
HTTP request
│
▼
Actix Web (Rust) ── routing (matchit) ── CORS · rate limit · compression
│
▼
Auth & guards (Rust, no GIL) ── JWT / API key / session · IsAuthenticated · Requires(...)
│
▼
Dispatch ── sync fast path (single GIL block) or async path (persistent worker loop)
│
▼
Your handler ── typed params · Depends(...) · Django ORM
│
▼
msgspec serialization ── zero-copy body ── HTTP response
🚢 Deployment
python manage.py runbolt --host 0.0.0.0 --port 8000 --processes 4
python manage.py runbolt --processes 4 --max-rss 512 # recycle workers above 512 MB
Multi-process scaling uses SO_REUSEPORT for kernel-level load balancing. Worker recycling, crash respawn, graceful shutdown, and WebSocket drain are built in. See the Deployment guide for systemd, supervisor, and reverse-proxy setups.

Django-Bolt stands on the shoulders of giants:
- Django REST Framework — ViewSet patterns, permission system, and overall API philosophy
- FastAPI — dependency injection, parameter extraction, and type-hint-driven design
- Litestar — OpenAPI plugin architecture, middleware and guard design
- Robyn — proved the potential of Rust-powered Python web frameworks with PyO3
- Actix Web, PyO3, msgspec, matchit — the foundations that make the speed possible
