Hi there, I developed a web app using Google's Firebase Studio. My app is using the gemini-2.0-flash model from Google AI via the Genkit framework. Now I want to publish it. However, Google charges for hosting and publishing. I do not have money to spend on the same. Could I host/publish it somewhere without compromising Google's terms and conditions? Or I just have to use Google's default services? I am also okay if Google charge users for app usage. Please guide me.
