Flet allows publishing your app as a static or dynamic website.

Static website - content is not changing and delivered exactly as it's stored. Python code is running in the web browser.

Dynamic website - content is dynamically generated for each user. Python code is running on the server.

Here is a table comparing Flet app running as a static vs dynamic website:

	Static website	Dynamic website
Loading time	⬇️ Slower - Python runtime (Pyodide) along with app's Python code and all its dependencies must be loaded into the browser. Pyodide initialization takes time too.	✅ Faster - the app stays and runs on the server.
Python compatibility	⬇️ Not every program that works with native Python can be run with Pyodide	✅ Any Python package can be used.
Responsiveness	✅ Zero latency between user-generated events (clicks, text field changes, drags) and page updates.	⬇️ Non-zero latency - user-generated events are communicated to a server via WebSockets. UI updates are communicated back.
Performance	⬇️ Slower - Pyodide is currently 3x-5x slower than native Python because of WASM	✅ Faster - the code is running on the server by native Python.
Code protection	⬇️ Low - app's code is loaded into a web browser and can be inspected by a user.	✅ High - the app is running on the server.
Hosting	✅ Cheap/Free - no code is running on the server and thus the app can be hosted anywhere: GitHub Pages, Cloudflare Pages, Replit, Vercel, a shared hosting or your own VPS.	⬇️ Paid - the app requires Python code to run on the server and communicate with a web browser via WebSockets.
