Pytisan

Async-first web framework for Python — elegant, productive, and fast.

Create an application (no install)

Like django-admin startproject, use uv and uvx (never pip):

uvx pytisan new my-blog
uvx pytisan new              # interactive prompt
uvx pytisan                    # same as `pytisan new`

This scaffolds a full app, runs uv sync --group dev, then:

cd my-blog
uv run anvil serve

Framework development

cd framework
uv sync --group dev
uv run python -m pytest

from pytisan import Application, Database, DatabaseConfig, Route, json

app = Application()


@Route.get("/users")
async def users():
    rows = await Database.table("users").where("active", True).order_by("name").get()
    return json(rows)


async def boot():
    await Database.connect(DatabaseConfig.sqlite("app.db"))
    await Database.execute(
        "CREATE TABLE IF NOT EXISTS users ("
        "id INTEGER PRIMARY KEY AUTOINCREMENT, name TEXT, active INTEGER DEFAULT 1)"
    )


asgi = app.asgi()

Database (SQLite)

Uses aiosqlite (async driver over SQLite / sqlite3):

from pytisan import Database, DatabaseConfig

await Database.connect(DatabaseConfig.sqlite(":memory:"))  # or "storage/app.db"

user_id = await Database.table("users").insert({"name": "Ana", "email": "[e-mail]", "active": 1})
user = await Database.table("users").find(user_id)
rows = await Database.table("users").where_like("name", "%An%").get()

Active Record (Model)

from pytisan import Database, DatabaseConfig, Model

class User(Model):
    __table__ = "users"

    id: int | None
    name: str
    email: str
    active: bool

    __casts__ = {"active": "bool"}
    __fillable__ = ("name", "email", "active")

await Database.connect(DatabaseConfig.sqlite("app.db"))

user = await User.create(name="Ana", email="[e-mail]", active=True)
users = await User.query().where(active=True).order_by("name").get()
user.name = "Ana Paula"
await user.save()

Migrations

from pytisan.database.migrations import Migration, schema

class CreateUsersTable(Migration):
    async def up(self) -> None:
        await schema.create("users", self._define)

    async def down(self) -> None:
        await schema.drop("users")

    @staticmethod
    def _define(table) -> None:
        table.id()
        table.string("name").not_null()
        table.string("email").not_null().unique()
        table.timestamps()

anvil make:migration create_users_table
anvil migrate run --database storage/app.db
anvil migrate status --database storage/app.db
anvil migrate rollback --database storage/app.db

uv run uvicorn examples.hello.main:asgi --reload

CLI

Installer (new projects): uvx pytisan new [name]

Anvil (inside a project):

uv run anvil --help

# Generators
anvil make:model User -m
anvil make:controller UserController
anvil make:request StoreUserRequest
anvil make:resource UserResource
anvil make:migration create_posts_table

# Migrations
anvil migrate run --database storage/app.db
anvil migrate status --database storage/app.db
anvil migrate rollback --database storage/app.db

# Dev server
anvil serve
