Depends on the webapp, traffic, etc. I have an EC2 instance and my own domain that runs me a solid $7 a month. It’s just a tiny little web server. If your web app is structured in a way that the client does the processing, your hosting costs can be pretty cheap.
For instance, rather than editing a PDF on a server, if your web app provides all of the tools to edit the PDF in the client’s browser, the server doesn’t need to be particularly robust. Basically it just needs to hand out those tools to the client.
I switched to exclusively Kagi on my phone and it’s been a pretty pleasant experience. Not perfect, but fairly serviceable. You’re right, it’s way less cluttered. Going back to Google can sometimes be very jarring.
