The modern full-stack web framework for Python.
Full-stack simplicity with modern Python performance.
⚠️ Early Alpha: Astris is currently in active alpha development. APIs and features may undergo breaking changes until production-ready status is confirmed. Feedback, bug reports, and ideas are welcome!
What is Astris?
Astris bridges the gap between the rapid, joyful developer experience of classic full-stack frameworks (like Laravel and Rails) and the raw performance, modern typing, and async concurrency of FastAPI and Python 3.11+.
By combining FastAPI, Inertia.js, Vue 3, Tailwind CSS v4, and SQLModel, Astris lets you build rich, dynamic single-page applications without the overhead of maintaining separate API layers or complex state synchronization.
🌟 Key Features
- ⚡ Lightning-Fast Core: ASGI performance powered by FastAPI and Uvicorn with auto-generated OpenAPI & Swagger documentation.
- 🧩 Modern Monolith with Inertia.js: Render Vue 3 components directly from FastAPI controllers with full server-side state hydration and zero REST boilerplate.
- 🛡️ Production-Ready Authentication: Cryptographically signed cookie sessions, OWASP-standard Argon2id password hashing (
pwdlib), and full-stack auth starter kit. - 🗄️ SQLModel & Alembic Database Engine: Unified declarative models, DTOs, and automatic schema migrations out-of-the-box.
- ⚙️ Type-Safe Centralized Configuration: Powered by
pydantic-settingsfor.envmanagement, type casting, and fail-fast startup validation. - 🪐 Orbit CLI: An artisan developer CLI for scaffolding modules, generating migrations, and serving full-stack applications with hot-reloading.
- 🎨 Tailwind CSS v4 Pre-configured: Instant zero-config styling powered by
@tailwindcss/vite.
🚀 Quickstart
Create a new full-stack Astris application in seconds using uvx (or pipx):
# 1. Create a new project
uvx --from astris-python astris new my_app
# Or install globally as a CLI tool:
# uv tool install astris-python
# astris new my_app
# 2. Enter directory and install frontend dependencies
cd my_app
npm install
# 3. Start full-stack development server (FastAPI + Vite HMR)
uv run orbit serve
Open http://localhost:8000 in your browser. Your full-stack app with authentication, Inertia.js, and SQLite is live!
💡 How It Feels
1. Controllers & Inertia Rendering
Write clean, expressive controllers that return frontend views or JSON seamlessly:
from astris.auth import AuthUser, auth_required
from astris.inertia import InertiaResponse
from astris.routing import Controller
controller = Controller(prefix="/dashboard", dependencies=[auth_required])
@controller.get("/")
async def dashboard_page(request: Request, user: AuthUser) -> InertiaResponse:
# Props are passed directly to Vue 3 with $page.props
return InertiaResponse(request, "Dashboard", props={"username": user["name"]})
2. Unified SQLModel Models
Define database tables and validation schemas in a single declarative model:
from astris.database import Field, SQLModel
class ArticleBase(SQLModel):
title: str = Field(index=True)
content: str
is_published: bool = Field(default=False)
class Article(ArticleBase, table=True):
id: int | None = Field(default=None, primary_key=True)
class ArticleCreate(ArticleBase):
pass
3. Frontend Views (Vue 3 + Inertia)
Build dynamic reactive pages without configuring client-side routers:
<script setup lang="ts">
import { Head, Link } from '@inertiajs/vue3'
defineProps<{
username: string
}>()
</script>
<template>
<Head title="Dashboard" />
<div class="min-h-screen bg-slate-950 text-slate-100 p-8">
<h1 class="text-3xl font-bold">Welcome back, {{ username }}!</h1>
</div>
</template>
🪐 The Orbit CLI
Astris comes equipped with Orbit, a developer toolkit for rapid development:
# Start FastAPI backend + Vite frontend concurrently
uv run orbit serve
# Scaffold a new domain module (controller, service, model)
uv run orbit make:module billing
# Create and apply database migrations
uv run orbit make:migration "create_billing_table"
uv run orbit migrate
# Generate encryption keys
uv run orbit key:generate

🙏 Acknowledgments
Astris is built upon the work of giants. Huge gratitude to the incredible open-source projects and creators that make Astris possible:
- FastAPI & SQLModel by Tiangolo - for setting the standard in modern Python type safety, speed, and ergonomics.
- Inertia.js by Jonathan Reinink - for the modern monolith architecture that bridges backend controllers and frontend SPAs without API boilerplate.
- Vue.js by Evan You - for the approachable and performant frontend component framework.
- Starlette & Uvicorn by Encode - for the lightning-fast ASGI toolkit and web server engine.
- Pydantic by Samuel Colvin & team - for rock-solid runtime data validation and centralized settings.
- Tailwind CSS by Tailwind Labs - for zero-config utility-first styling.
- Laravel by Taylor Otwell - for inspiring developer-first framework craftsmanship.
