webpy

Make a website with plain pygame. webpy streams your pygame window to any browser tab.

pip install webpygame

import webpy

screen = webpy.display.set_mode((800, 500))
clicks = 0
button = webpy.Rect(300, 220, 200, 60)

while True:
    for event in webpy.event.get():
        if event.type == webpy.MOUSEBUTTONDOWN and button.collidepoint(event.pos):
            clicks += 1
    screen.fill((30, 34, 48))
    webpy.draw.rect(screen, (90, 94, 235), button, border_radius=12)
    webpy.display.flip()      # sends the frame to the browser

Run it, and your browser opens. Every browser tab gets its own copy of your site.

• webpy.display.url(): the address for other computers on your network
• webpy.display.public(): a public link that works from anywhere (uses Cloudflare's free cloudflared)
• webpy.display.set_url("/about"): change the address bar
• webpy.settings: change defaults (public, share, separate_tabs, max_tabs, fps, ...)

Everything from pygame is available as webpy.something too.
