## From Snake to a neon shoot 'em up Everything a 2D game needs is already in Pyzed: a GPU canvas, a loop that runs once per frame, the keys held down right now, sprites and particles, and the whole widget library for menus and HUDs. - Three complete games, explained step by step: **Snake**, **Breakout** and **Neon Invaders** - `pz.frames` for a smooth 60 fps loop, held keys and mouse input - Bloom, glow and glass on top of the action, written in plain Python ## The libraries you already use Pyzed is only the interface: the rest of your app is ordinary Python. Runnable demos show how to put a native desktop front end on the backend stack you know. - **FastAPI** client with the server embedded in the same process - **SQLAlchemy** and **SQLModel**: 20,000 rows in a virtual table, forms validated by your models - **Django**'s async ORM, **httpx** and **Pydantic**, **aiosqlite** and more ## A Python GUI for a new generation tkinter, Kivy and PyQt made Python desktop apps possible. Pyzed makes them look and feel like the tools you use every day, and is honest about where the others still win. ## Batteries included The details that turn a prototype into an app people enjoy using. pyzed dev andpyzed run --reload.',

## An app in 20 lines
Prefer to write everything by hand? Pyzed is a regular Python library. This is a complete app:
```python title="counter.py"
import pyzed as pz
from pyzed import ui
class Counter(pz.App):
title = "Counter"
size = (360, 220)
def __init__(self):
self.count = 0
def add(self, step):
self.count += step
def view(self):
return pz.center(pz.column([
ui.heading(str(self.count)),
pz.row([
ui.button("1", lambda: self.add(-1), icon="minus"),
ui.button("1", lambda: self.add(1), icon="plus", variant="solid"),
ui.icon_button("rotate-ccw", lambda: setattr(self, "count", 0)),
], spacing=8),
], spacing=16, align="center"), bg=self.theme.editor)
pz.run(Counter)
```
