In Firebase Authentication Limits it states that new account creation limit is 100 accounts/IP address/hour. I could not find any further explanation on this, i.e. what happens if the limit is exceeded, because it is very likely that there might be more than 100 new user creation after the launch of the app or a successful marketing campaign.
It states that "You can schedule a temporary increase to the account creation limit in the Firebase console."
Is that a paid service? How much does it cost? How long is temporary? How often can it be scheduled?
To add to the Frank van Puffelen's answer, this is easily customizable via the Firebase console: Authentication tab -> Manage sign-up quota (at the very bottom) to get this:
The IP limit is in place to protect your project against abuse. Setting a temporary increase is available to all Firebase projects, free or paid.
I don't think there is any documented limit to how often you can increase this, although that too is monitored for abuse.

The firebase documentation includes a warning that if you use a kill switch to stop using firebase when a budget cap is exceeded, as follows:
Warning: This example removes Cloud Billing from your project,
shutting down all resources. Resources might not shut down gracefully,
and might be irretrievably deleted. There is no graceful recovery if
you disable Cloud Billing. You can re-enable Cloud Billing, but there
is no guarantee of service recovery and manual configuration is
required.
I'm trying to investigate what gets irretrievably deleted. Does the datastore get deleted when the kill switch is activated? Is there any opportunity to save data previously stored in cloud firestore, before the deletion takes place? Is there a way to download the database so that I can keep a back up in this scenario?
Please review the following reply from Firebase Team member(samstern) to gain more clarity on this:
these things are handled on a per-product basis and each product has different thresholds for quota overages and different procedures for what happens to inactive resources in a bad state.
For instance I know in Realtime Database if your DB is too big for the
free plan after you downgrade from a paid plan we will not delete
your data automatically. Instead you'll just be stopped from using the
database until you restore your billing.
However that statement clearly says that some products may delete data
if you pull Cloud Billing. It could be for technical reasons, it could
be for policy reasons.
If you want to turn off a product without risking this pulling your
billing account is NOT the best way to do this. It's the nuclear
option if you get into a bad situation and want to get out at all
costs. Instead you should use per-product APIs to shut down the
individual product or service and prevent future usage. This could
include doing things like flipping off APIs in the APIs console,
changing security rules to prevent all further writes, deleting Cloud
Functions, etc
The best source of information I've been able to uncover in answer to this particular question is a discussion on reddit which indicates that you can't recover access to your data, until you pay the bill (including blow out charges) - so maybe that buys some time, but if you don't pay, the project gets deleted. There may also be lost data for things happening at the time the kill switch activates.
Some functions in the Google Developers Console, like the Analytics API, are free until you reach a quota. Other functions, like Google Cloud Storage, create costs from the first click.
When I upload a file under https://console.developers.google.com/ > Storage > Cloud Storage > Storage Browser and I make this file publicly available, I pay about $0.12 per GB traffic.
But theoretically the traffic to this link could explode, e.g. because of sudden popularity. Therefore I would like to set something like a daily or monthly cost limit.
Q: How do I protect myself from overly high costs in the Google Developers Console?
You cannot. I asked Google about this, here's their response, from May 7 2016:
(GCE = Google cloud engine. No spending limits.
GAE = Google app engine — yes it has spending limits.)
... you are eligible for support on ... only ...
... [various helpful links] ...
That been said, at the moment there is no a feature that allows you to
configure a limited budget on GCE. This feature is certainly available
for GAE [1]. As you mentioned in your comments, you either can totally
shut down your VMs (will depend on your use case) or set the VMs to
send you alerts if they reach a certain traffic limit [2].

#wmdry, you wrote: "traffic to this link could explode" — I'm afraid of this too. That's why I asked Google about this. And I'm planning to avoid Google's CDN because of this, and use another CDN provider instead, which has spending limits. Because, unlike Nginx, I don't see any way for me to rate limit / throttle Google's CDN.
I do plan to use GCE (Google Cloud Engine) though. Therefore, right now I'm reading about how to rate limit my Nginx server. Because if I just configure Nginx correctly, then those $0.12 / GB you mentioned, cannot possible explode to ... like $10k in a month? What if Google sends a $10k bill when I'm back from an a few week's vacation, just because of my hobby project and a few people downloading a 1 MB movie over and over again forever (because: evil). Hmm, & the bigger & faster my servers, the higher the risk.
I hope Google will add spending limits, because I did want to use Google's CDN.
Update 2020: Apparently this does bite people from time to time — look here:
"Burnt $72k testing Firebase and Cloud Run and almost went bankrupt", Dec 08, 2020, https://news.ycombinator.com/item?id=25372336,
In that case, they could contact Google and in the end didn't need to pay.
As of July 2017 you can set budgets that send notifications via email but do not cap spending:
To set an alert-only budget, which will not cap spending:
Go to the Cloud Platform Console.
Open the console left side menu and click Billing
If you have more than one billing account, click the billing account name.
On the left, click Budgets & alerts.

I found that Google's documentation now provides two methods to actually limit the cost of a GCP project. It involves the following setup:
Create a Cloud Function that checks the cost against the budget, and carries out a certain action if the cost exceeds the budget. Google's Documentation provides a sample code snip that can either shutdown all VM instances in a Project or disable the billing for a project. Shutting down all VMs would stop all VM-related cost but you get to keep your data (and still have to pay for the storage). Disabling the billing for a project would effectively zap all cost-related activities and you could lose data. You can name the Cloud Function "budget-enforcer".
The Google code snip as provided above has a hard coded ZONE variable. Remember to change it to match your zone!
Create a Service Account to run the Cloud Function "budget-enforcer". For shutting down VMs, the Service Account would need role "Compute Instance Admin (v1)". For disabling billing on a project, the Service Account would need role "Project Billing Manager".
Set a Topic for the Cloud Function (I call mine "proj-name-stop-vm" and "proj-name-disable-bill").
Set up a budget alert as usual, and connect it to one of the Pub/Sub topic above.
Please be noted that Google's documentation did mention that there could be a delay between the cost exceeds a budget and the function is triggered, so you should build in a buffer if you have an absolute hard cost limit. I use 90% of the budget as the trigger line for shutting down my instances.
The API usage can be limited with a hard limit:
Depending on the API, you can explicitly cap requests in a variety of
ways, including: requests per day, requests per 100 seconds, and
requests per 100 seconds per user. You might want to limit the
billable usage by setting caps. For example, to prevent getting billed
for usage beyond the free courtesy usage limits, you can set requests
per day caps

You can combine budget pub/sub alerts with a cloud function that can disable billing on your entire account if a threshold is met.

To Disable Billing
const _disableBillingForProject = async projectName => {
const res = await billing.updateBillingInfo({
name: projectName,
resource: {
billingAccountName: ''
}, // Disable billing
});
console.log(res);
console.log("Billing Disabled");
return `Billing disabled: ${JSON.stringify(res.data)}`;
};
Simply go to the developer console:
https://console.developers.google.com/project
Select your project.
Select "billings & settings"
Enable billing.
Then go to Compute/AppEngine/Settings and set a daily budget.
Go to Google Cloud console, and then to Billing / Budgets and Alerts and create a new budget for one or all your projects. You can select which services should be included in the limit and set a monthly amount that should not be exceeded.
I'm currently working in a social network app and I need to do a search feature. Firestore does not support these kind of queries, so I need to use an external service like Algolia.
The problem is that the free plan does not support connecting to external websites/APIs other than Google's own ones, so I can't connect to Algolia to get my search system working.
I have read multiple stories about devs paying high bills because of loops or errors in their code, and as the Blaze plan is a pay-to-go plan, they get charged what they used. If a loop generated 10TB of files they will get charged for that.
I also know that Blaze plan's features are free as long as each of them (individually) stay below the limits of the free Spark plan.
So as my question says, is there a way to set limits? For example, I would like to tell Firebase to limit my cloud functions invocations to 100k per month. That way it would be free and I would never be able to get over 100k as it's limited, which means I'll never get billed for that.
Take into account that the only thing I need right now from a paid plan is the connection to external networks. I don't need anything else as we're just starting and the app is not in production, so there's no need for huge limits.
Every Firebase project is also a Google Cloud Platform project. This means that many of the advanced features of Google Cloud Platform are also available for your Firebase project.
For example, you can set up billing alert for your Firebase project, so that you are alerted when the usage reaches a certain level. While you can't configure it to switch off the project at some point, the alert should typically be quite good for alerting you to unusual usage patterns.
For more on this see:
Tracking your spending with budgets in a recent blog post.
The GCP documentation on how to set budget alerts, which is what Firebase uses under the hood.
The GCP documentation now also has a section on capping (disabling) billing to stop usage. This is a brute force approach though and may lead to data being lost, so I'd recommend investigating all other options first.
Update (December 2020): Firebase's Todd Kerpelman just released a series of videos where he disables billing using the process from the documentation mentioned above.
You cannot set spending limits to your app now.
As of December 12, 2019, you can no longer create spending limits, but
you can change or remove existing spending limits.
https://cloud.google.com/appengine/pricing#spending_limit
You can create budgets, which will alert you when reaching the budget. But it won't stop the usage when hitting the budget.
https://cloud.google.com/billing/docs/how-to/budgets#add-new-budget
The screenshot here seems to show a Spending Limit setting for Firebase projects: Firebase: Budget and Daily Spending Limit
That settings page is located here (the Spending Limit setting apparently only shows up once you set up billing for the project): https://console.cloud.google.com/appengine/settings
It's disabled in the poster's case, but I think that's only because he connected it up to a "NodeJS App Engine app", which isn't the case for many Firebase developers.
I haven't tried it yet myself, but will do so once I start a paid plan.
EDIT: Yep, the setting shows up once you switch to a paid plan. (in my case, Blaze) I don't have enough traffic yet to confirm that it works as expected, but if I find later that it doesn't, I'll give an update here.
"This example shows you how to cap costs and stops usage for a project by disabling Cloud Billing. This will cause all Google Cloud services to terminate non-free tier services for the project."
Google Cloud Source
I am a Google blaze plan user and I have an express server containing a simple endpoint that just pulls from firestore. During high traffic hours, I can retrieve 5000+ simultaneous read requests which eventually throws this error below,
Error: 8 RESOURCE_EXHAUSTED: Quota exceeded.
After I wait a few minutes I am able to read the collection again.
Update:
Unsure why the downvotes without any explainations.. but I also have a Mutex system which I think may be leading to hitting these limits. If fails to lock a document using transactions, it goes down an array of snapshots until a lock is given. If the array becomes empty, it does another read to firebase for another set of N documents, which is only 50 in my case.
So my question is, is there a limit on the amount of transactions or reads per second that we're allowed to do from a single connection (my express server)? I don't think it's stated anywhere in the documents.
It looks like you're reaching one of the read/write/transaction limits stated in this page.
Might be this one Maximum writes per second per database: 10,000 (up to 10 MiB per second) but I'm only guessing...
To answer your question, according to this link, the maximum concurrent connections for mobile/web clients per Firebase database is 1,000,000. Thus, your connections seem to not exceed the limits.
For the Blaze Plan project, the limit for Cloud Firestore Document Read is 50K/day, since free usage from Spark Plan is included in Blaze Plan. The limit is such, unless you have set any budget limit in your Billing account. The usage will be reset at midnight of PST. If you upgrade your plan to Flame Plan, the limit is 250K/day.
Here you may read about the official Cloud Firestore Quotas and limits, such as maximum document reads, maximum size for a document, that can be useful. Furthermore you may monitor your database usage and check your plan's limits from the “Usage” tab in the Firebase console. You can check usage over the current billing period, the last 30 days, or the last 24 hours.
Stackdriver Monitoring is also a practical tool for monitoring document reads/writes/deletes, active connections and snapshot listeners.
A good practice, if you want to avoid unexpected charges on your billing account, would be to create an alerting policy based on the Cloud Firestore metrics, as stated here.
Additionally, you can estimate and verify your monthly costs on the “Blaze Plan” by using this Blaze Plan calculator.
For anyone who runs into this issue in the future, please check your App Engine budget settings under "Application Settings". I set the daily spending limit to avoid unnecessary charges during testing and it slipped my mind. I increased the budget and the error is currently gone.
AWS usually sends me an email when my budget has been exceeded.
While trying to add a new project in Firebase, it's showing the warning as:
You've reached the project limit for your account.
You can add Firebase to an existing project or request an increased limit.
Request an increase // button
Later I checked in Google Developer Console and deleted all existing projects in there. Still this issue persists and I am not able to create a new project in Firebase. Any help is appreciated.
While this is likely answered on the Firebase maximum projects and apps question, the most important parts are from Frank van Puffelen's (a Firebase engineer) comments on the Cannot create new project in Firebase console question:
The projects are pending deletion. It takes a week before they actually are permanently deleted.
There's no limit on the number of projects in general, but there is a limit on the number of projects on an unpaid plan. The exact limit for that varies, from what I understand.
Furthermore, the Cloud Platform Console Help section explains why these limits are in place:
Why are there limits to how many projects I can create?
Quotas protect the Google Cloud Community from unforeseen spikes in usage. However, as your usage of Google Cloud Platform increases, you can request an increase in your quota.
