Thanks for posting! Unfortunately, there isn’t a great way to save your app as an HTML file, but this thread has some suggestions and there’s an open GitHub Issue here for this feature enhancement.
Hi @minhnguyen168
Here is a new method to save streamlit app as an HTML
I found some discussion for you to conquer your problem:
Add support for sharing static apps to a local folder: Static App Support
Export to standalone HTML file: HTML Standalone
I hope these discussions will help you in finding your answer in an easy way.
Thank you
