I tried to make a reddit like app. I used both realtime-database and firestore as database. The billing of the two is different from each other. I used realtime-database for frequently updated data (like or upvote, downvote count for ex.) and firestore for more stable and large data (post, comment, community and user data..). While doing this, I only used database rules, I did not use Cloud functions. So, I suggest you use a hybrid database to minimize your bill as much as possible and you can do amazing things with database rules. Have a good works.

const functions = require("firebase-functions"); // // Create and deploy your first functions // // https://firebase.google.com/docs/functions/get-started // // exports.helloWorld = functions.https.onRequest((request, response) => { // functions.logger.info("Hello logs!", {structuredData: true}); // response.send("Hello from Firebase!"); // });

Try something along these lines…? https://github.com/firebase/functions-samples/tree/main/Node-1st-gen/quickstarts/email-users

That would be a Firebase Cloud Function. Check their latest list of YouTube tutorials, they'll guide you through creating an app with full Firebase features.
