Based on the latest tests I've published, Django LiveView appears to be the fastest dynamic frontend (I'm sure more variables can be measured).

OK... but... How can I test its limits? By drawing a Snake? A Pac-Man?... No... let's crank up the difficulty to Nightmare! Let's run DOOM inside Django 😈

(If you don't see the video playing, please tap the image.)

Django starts ViZDoom and sends one <div> per pixel with its color. The game runs at 100x100 pixels at 60 FPS = 600.000 divs/second! 😵‍💫

Here's how the data flows:

1. ViZDoom generates a frame.
2. Django transforms the frame into 10.000 divs using its template engine.
3. Django LiveView renders them on the page of connected users.
4. CSS arranges them.

Furthermore, since the data is sent via broadcast, all players can see the same thing in real time.

Crazy.

Mission accomplished! Django LiveView survived the DOOM stress. It was a ridiculous and fun experiment that proves this framework can handle pretty much anything you throw at it.

Now go build something cool without Doom Slayer.
