I would like to know if Firebase Cloud Messaging is free or not for unlimited users?
In addition to the answer from AL.
From the Pricing page Faqs:
Which products are paid? Which are free?
Firebase's paid infrastructure products are the Realtime Database,
Firebase Storage, Hosting, and Test Lab. We offer a free tier for all
of these products except Test Lab.
Firebase also has many free products: Analytics, App Indexing,
Authentication, Dynamic Links, Cloud Messaging, Notifications,
Invites, Crash Reporting, &, Remote Config. You can use an unlimited
amount of these in all plans, including our free Spark Plan.
So, it's free. The limit is not mentioned anywhere in the docs, however there's a limit on the Firebase realtime database, as mentioned in the FAQs:
Firebase imposes hard limits on the number of connections to your app's database at the same time. These limits are in place to protect both Firebase and our users from abuse.
The free plan limit is 100, and cannot be raised. The Flame and Blaze
Plans have an initial limit of 10,000 simultaneous database
connections. This is to prevent abuse and can be raised by contacting
Firebase support with 24 hours notice.
This limit isn't the same as the total number of users of your app,
because your users don't all connect at once. We encourage you to
monitor your peak simultaneous database connections and upgrade if
needed.
We're working hard to remove the initial 10,000 simultaneous
connection cap on the Flame and Blaze plans.
So if you are using the Firebase Database to save your User's data and want to send a lot of Push Notifications to your user's devices using the FCM registration token stored in the Firebase Database, you might hit the limit in the free Spark plan, however it's really tough to hit the 10k limit.
From the Firebase Cloud Messaging Docs:
Firebase Cloud Messaging (FCM) is a cross-platform messaging solution that lets you reliably deliver messages at no cost.
You can refer to the official Firebase Pricings page. From there you will be able to see the types of projects that are available: SPARK, FLAME, BLAZE, to which all of them have FCM (along with Analytics, App Indexing, Authentication, Dynamic Links, Invites, Notifications, Crash Reporting & Remote Config) included for free.
Firebase Cloud Messaging (FCM) Connection Server (CCS) sits between the device and the app server. The following limits apply
From the documentation here, it seems FCM does impose a limit of 1000 connections in parallel.
For each sender ID, FCM allows 1000 connections in parallel.
Sender Id is a unique numerical value created when you create your Firebase project, available in the Cloud Messaging tab of the Firebase console Settings pane. The sender ID is used to identify each app server that can send messages to the client app.
Note: Please correct me if this limit is not about the max connections from an app server to CCS
Secondly, You should also read about Flow Control if you are using the XMPP connection server protocol (which has to be used if using device-to-cloud messaging). There should not be more than 100 unacknowledged messages towards CCS at any single point of time.
If the pending message count reaches 100, the app server should stop sending new messages and wait for CCS to acknowledge some of the existing pending messages

Hello Everyone,
I have create gmail app and complete all types of functionality but one functionality not implemented this one is mail receive in our gmail app.
Me search any types solution for receive mail and i have found one solution is google cloud Pub/Sub but this pub/sub how to implemented in our app is not idea show please tell me any one how to used pub/sub in android.
Cloud Pub/Sub is not the right choice for receiving messages on Android. The service is designed for inter-service communication. Using it on Android would present two problems:
The limit on the number of topics and subscriptions per project. Only 10,000 topics and subscriptions are allowed and only 10,000 subscriptions per topic. If you plan to scale out to many devices, you will run up against these limits quickly.
Security/authentication issues. You would need to ship the credentials within the Android application and so you will either have to generate service accounts for every individual device or use the same one across all devices. What do you do if those credentials are compromised? In the former case, you have to keep track of all of them and revoke the right one. In the latter case, revoking the privileges means all of your devices stop working.
You need something like Firebase Cloud Messaging to send data to Android devices. You may use Cloud Pub/Sub as a means to generate notifications out of GMail, but the subscriber would be another server-side application or perhaps a Cloud Function that passes the notification on via Firebase Cloud Messaging.
I'm developing an application on Xamarin Android similar to uber but I need to make real-time notifications of travel request, cancellation and location, any idea how to do it?
There are several choices you can choose:
1. Firebase
You can to use Firebase to provide real-time notifications.
By using only two Firebase features, you can create real-time notifications for users: the Firebase Realtime database for web users , and Firebase Cloud Messaging for Android users.
What the Firebase Realtime database provides us with is the ability to save, retrieve and sync our data with our NoSQL cloud database. We can sync data across all clients in real time. The Firebase Realtime Database is simply a cloud-hosted NoSQL database and the data is stored as a JSON and synchronized in real time to every connected client.
For more details, you can check: https://www.atlantbh.com/blog/using-firebase-provide-real-time-notifications/
2. SignalR
Azure Mobile Services has SignalR integrated, and Azure Mobile Services provide a SDK for client apps, I suppose it is provide out-of-the box.
You will find many capabilities included in Mobile Services and
readily available for your Web API. Mobile push notifications,
real-time notifications with SignalR (auto-scaled out), social auth
for your consumer apps, offline data sync for occasionally connected
scenarios, to name a few.

3.PubNub
Live Notifications of it keep everyone, and everything, realtime with live notifications across HTTP, SMS, FCM, APNS2 and more.

4. Pusher
PubNub and Pusher are all offerring real-time infrastructure as a service and all the benefits that come with that. Both of these solutions are pub/sub. Pusher also offers an additional event abstraction: Evented PubSub.

From what I understand, when sending notifications from the Firebase compose message console from https://console.firebase.google.com/u/0/project/[projectname]:api-project-[senderID]/notification/compose, only CPU and bandwidth from the Google servers is consumed because the notifications are sent directly from the Google servers, not from mine, correct? If I use cURL to trigger push notifications from my servers, it would still use Firebase and Google servers to send and deliver the notifications, and it would not consume CPU and bandwidth from my servers, correct?
I am trying to fully understand whether or not sending push notifications directly with Firebase Cloud Messaging and without third party solutions such as Urban Airship is CPU and bandwidth intensive on my servers. I am not sure if part of the features/benefits that third party push notifications solutions offer is handling CPU/bandwidth intensive tasks, or if that is something that the Google servers handle directly when connecting and sending push notifications directly with Firebase Cloud Messaging.
I know StackOverflow is not for questions that arise debate, especially about architectures and in-house versus third party software solutions, but the main purpose of my question is knowing who handles the CPU and bandwidth intensive work when push notifications are sent to thousands of devices, is it the Google servers (Firebase Cloud Messaging servers), or the servers of the software company that provides the push notifications service such as Urban Airship, or the servers that trigger the push notifications in case the Firebase Cloud Messaging configuration is built in-house without third party solutions? Thank you.
EDIT: The answer at Why and how is push-notification (like GCM) battery efficient? includes this paragraph: "The android device keeps a single connection open to GCM servers to listen for notifications". However, it still does not answer my question because even though I know that the Firebase Cloud Messaging servers are responsible for sending the push notifications, I am still trying to understand if my servers do not have to provide CPU power or bandwidth at all, even if I use cURL to trigger the push notifications from my server using PHP cURL functions and cron jobs, for instance. If I can make an analogy, imagine using jQuery by importing the library directly from https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js versus downloading the jquery.min.js file and then putting it on your server. If you use https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js you would be using resources from Google servers, not from your own servers. If you download the jquery.min.js to your server, then visitors would be using resources from your own servers, not from Google's servers. That is my analogy, so in the case of push notifications using Firebase Cloud Messaging without third party solutions such as Urban Airship, I was wondering who provides the CPU power and bandwidth, your own servers or Google's servers. Thank you.
In that case, it should be fairly simple if you use a mechanic like GCM topic. It should not be CPU intensive since you are not sending to each individual user but just one broadcast to the topic and let Google do the heavy lifting.

I have an app and I need to send massive push notifications per day. About Firebase services, I'll just use the Firebase Cloud Messaging (FCM) part (through my server-side PHP, of course I can't send massive notifications per day by console) and maybe Analytics (both are free of charges, right?).
The Pricing Page doesn't make a good explanation about what is each line below. So I need to know if:
If "Storage Upload operations" is when the app sends to Firebase some data?
If "Storage Download operations" is when the console (or my Server Side) sends to a device/group/all some push notification?
If I'll only use the Cloud Messaging part, is it better buy the BLAZE plan? If yes, what exactly do I have to add at this plan?
First, I think you are confusing the Notification service with the Cloud Messaging service (hence my edit).
Notifications is the part where you get to send Push Notifications through the Firebase Console. Cloud Messaging, is FCM itself, where you can call the APIs and send push notifications from your own App Server.
Firebase Storage is a separate service from both Cloud Messaging, Notifications, and Analytics. The thing is that Firebase Storage is paid and the other three are included free of use, regardless of what plan you are using. As seen in the Pricings Page:
Included Free
Analytics, App Indexing, Authentication, Cloud Messaging, Crash Reporting, Dynamic Links, Invites, Notifications & Remote Config
It does not contribute/add to the count value of usage for the other services.
There are only four paid Firebase products at present:
Firebase Realtime Database
Firebase Storage
Firebase Hosting
Firebase Test Lab
All other products including Firebase Cloud Messaging are free to use. Firebase Storage is a totally separate product from Firebase Cloud Messaging, so this question isn't really relevant.
I need to implement push notification feature in my application. Exploring some options.
Google recently recommends Firebase platform, but this is not completely a free service. So I thought of using GCM again. Will google stop support for GCM in future?
Firebase Cloud Messaging is free of charge, just like Google Cloud Messaging was. The Firebase pricing page shows exactly what Firebase features are paid.
Yes, it's free. You can use Analytics for advanced messaging - out of the box.
Which products are paid? Which are free?
Firebase's paid infrastructure products are the Realtime Database,
Firebase Storage, Hosting, and Test Lab. We offer a free tier for all

As of April 10, 2018, Google has deprecated GCM. The GCM server and client APIs are deprecated and will be removed as soon as April 11, 2019. Migrate GCM apps to Firebase Cloud Messaging (FCM), which inherits the reliable and scalable GCM infrastructure.
There is no such thing "unlimited" for free.
If you will send billions of billions messages a day, you will likely hit the maximum throughput limits and get blocked, or perhaps some sales man will contact you.
https://firebase.google.com/pricing/
This link should help you understand better. If you are implementing push notifications my suggestion would be that maintain your own database for the generated device tokens instead of using topic messaging.
Two reasons why I avoided topic subscription is :
There is a limit to the number of topics you can subscribe in free plan
Topics are not subscribed immediately
Although the number of active users allowed in parallel connection has a limit but its too much to exceed that easily.
P.S. I use the spark plan by the way
It’s free but limited with rates - see https://firebase.google.com/docs/cloud-messaging/concept-options
No clue how Telegrams handles to work with this at their 700M active users paste.
My guess they opened hundreds of cloudflare projects and invoke the api in a round robin with some custom proxies and load balancers.
Not completely free. This is the pricing strategy.
