What is the meaning of the following?
50 Max Connections, 5 GB Data Transfer, 100 MB Data Storage.
Can anyone explain me? Thanks
EDIT - Generous limits for hobbyists
Firebase has now updated the free plan limits
Now you have
100 max connections
10 GB data transfer
1 GB storage
That means that you can have only 50 active users at once, only 5GB data to be transferred within one month and store only 100 MB of your data.
i.g. you have an online web store: only 50 users can be there at once, only 100 mbytes of data (title, price, image of item) can be stored in DB and only 5 GB of transfer - means that your web site will be available to deliver to users only 5gb of data (i.e. your page is 1 mbyte size and users will be able to attend that page only 50 000 times).
UPD: to verify the size of certain page (to define if 5gb is enough for you) - using google chrome right click anywhere on page - "Inspect Element" and switch to tab "Network". Then refresh the page. In bottom status bar you will amount of transferred data (attached size of current stackoverflow page, which is 25 kbytes)
From the same page where the question was copied/pasted:
What is a concurrent connection?
A connection is a measure of the number of users that are using your
app or site simultaneously. It's any open network connection to our
servers. This isn't the same as the total number of visitors to your
site or the total number of users of your app. In our experience, 1
concurrent corresponds to roughly 1,400 monthly visits.
Our Hacker Plan has a hard limit on the number of connections. All of
the paid Firebases, however, are “burstable”, which means there are no
hard caps on usage. REST API requests don't count towards your
connection limits.
Data transfer refers to the amount of bytes sent back and forth between the client and server. This includes all data sent via listeners--e.g. on('child_added'...)--and read/write ops. This does not include hosted assets like CSS, HTML, and JavaScript files uploaded with firebase deploy
Data storage refers to the amount of persistent data that can live in the database. This also does not include hosted assets like CSS, HTML, and JavaScript files uploaded with firebase deploy
These limits mentioned and discussed in the answers, are per project
The number of free projects is not documented. Since this is an abuse vector, the number of free projects is based on some super secret sauce--i.e. your reputation with Cloud. Somewhere in the range of 5-10 seems to be the norm.
Note also that deleted projects take around a week to be deleted and they continue to count against your quota for that time frame.

What I considerd data transfare in firebase hosting according to docs
Data transfer (GB/month) — The amount of data transferred to end users from our CDN. Every Hosting site is automatically backed by our global CDN at no charge
So is when a user go to my domain and firebase send the user my web site that lets say for the sake of argument has 100mb so each 10 requests will cost me 0.15 usd according the pricing on fire base ?
Data transfer $0.15/GB
My current concern that my react build folder has the size of 3mb since it has too many pngs in it … so will I pay for the transfare of this build folder to end client each time a Client call this site ?

Yes, you are charged on the data downloaded from CDN/server.

It'll be best to optimise and compress your images to reduce costs and also loading speed.
so will I pay for the transfer of this build folder to end client each time a Client call this site
Some static assets should get cached locally so the next time user loads the site it might load them from cache instead of the server. So it won't be 3 MB always.
You can get rough estimate of the data being loaded in the network tab of browser console.
For my application it is important to synchronize data between the client and server constantly. I'm thinking of integrating Firestore in my application, but I am wondering what the bandwidth of my collection(s) would be.
As I see it, every time Firestore synchronizes client side and server side, it fetches the entire collection from the server side and checks the differences between the two on the client side. This is a crude, but effective strategy. However, I can't be pulling in what is currently 100kb of database data every few seconds.
The application is loaded onto tablets that have a monthly max of 10GB 4G data. I can't exceed this limit and I don't intend to. By my calculations running this application with a sync of every 10 seconds on 1 tablet for 8 hours a day, 31 days a month, it will use 8.928GB of data. This would suffice for now, but what do I do when my collection size grows to 200 or 300kb?
My question:
How often does Firestore sync data and is there any way I can avoid pulling in the entire collection every single time while still keeping 100% data integrity?
Firestore offers 50000 documents read operations as part of its free bundle.
However, in my application, the client is fetching a collection containing price data. The price data is created over time. Hence, starting from a specific timestamp, the client can read up to 1000 documents. Each document represents one timestamp with the price information.
This is means that if the client refreshes his/her web browser 50 times, it will exhaust my quota immediately. And that is just for a single client.
That is what happened. And got this error:
Error: 8 RESOURCE_EXHAUSTED: Quota exceeded
The price data are static. Once they have been written, it is not supposed to change.
Is there a solution for this issue or I should consider other database other than Firestore?
The error message indicates that you've exhausted the quota that is available. On the free plan the quota is 50,000 document reads per day, so you've read that number of documents already.
Possible solutions:
Upgrade to a paid plan, which has a much higher quota.
Wait until tomorrow to continue, since the quota resets every day.
Try in another free project, since each project has its own quota.
If you have a dataset that will never-ever (or rarely) change, why not write it as JSON object in the app itself. You could make it a separate .js file and then import for reading to make your table.
Alternatively - is there a reason your users would ever navigate through all 1,000 records. You can simulate a full table even with limiting to calls to say 10 or so and then paginate to get more results if needed.
I've been trying to do some research into the use of Dynamic Links with Firebase and was curious if anyone knew of any limit on the number of dynamic links we can use. For example, we're looking to generate links server side which is dynamic and will log users into our apps. However, this will go into the 10,000s. so will this be a bit too extreme for Firebase and therefore not a viable solution?
Thanks in advance.
That should be fine - the limits on FDL will be in terms of how many you can create per second, so as long as you spread the creation out, you should be fine.
Based on my (short) experience, if using the free plan there is a limit of 100 links per 100 seconds per user, which means if you generate links on the backend (like I do) you are basically limited to creating 1 link per second, which is not much. If you exceed this limit you receive an error like this:
429 Too Many Requests
Insufficient tokens for quota 'DefaultQuotaGroup' and limit 'USER-100s' of service
Also a lot of times the Dynamic Links API returns error 503 Service Unavailable when generating links instead of 429, I don't know why but I don't think they have availability issues. It's just kind of confusing.
Here is what I see on my project's quotas page:
Default quota. per day 100,000
Default quota. per 100 seconds 5,000
Default quota. per 100 seconds per user 100
We've been developing with Firebase for a couple of months and recently we've seen some long delays in downloading data (e.g. 20 seconds). During those times the "forge" web UI is also tremendously slow to respond.
After a while, it seems to clear up and go back to its lightning-fast self.
Could this be because I'm using a significant portion of the free quota (80 MB / 100MB of storage and 1.6 GB / GB in bandwidth)? Are there undocumented rate limits we're hitting?
The last time this happened we had 6 concurrent users, and our alltime peak so far has been 13.
The short answer is no, dev accounts aren't rate-limited. They're capped on connections, data storage, and monthly data transfer, but there's no rate-limiting.
If you're having performance issues, your best bet would be to email support#firebase.com detailing what you're seeing and the name of your Firebase so that we can investigate. Typically, delays are the result of large data transfers going into or out of your Firebase (e.g. downloading your entire Firebase, which could be accidentally triggered by opening Forge) and there are usually mitigation strategies that we can help you out with.
