Do you know any service that does that? Right now I have reached 5GB of my phone contract and I have to navigate with a very low speed. I was thinking to write a simple service that takes the URL as request and sends back the page but in read mode or in a very minimal way keeping focus only on the content. But I want to check if a service like this already exists.
At the end I wrote my own little “search engine” to do that. Still buggy and not super fast, but it does what I need and I can now navigate also wit a bad connection https://blaze.cyclic.app
