android - Use Firebase connections properly for building a chat app -

i'm evaluating firebase building chat app. , it's plan makes me concern: 10,000 concurrent connections/$1,499/month.

it seems me chat app have always-on connection firebase, receive incoming messages instantly. means if app 10,000 active installs on android, no matter whether they're opening app or not, have pay $1,499/a month.

anyone know solution reducing concurrent connections firebase without impacting perceived quality of chat app? thanks.

note

this chat app, , perceived quality of chat app important. connection on android never released if device has net connection.

having 10k users or 10k downloads of app not equate having 10k concurrent users logged in , looking @ chat app @ same time.

a more accurate rule of thumb 1 concurrent > 1200 monthly visits typical website or app (apps average higher). example, 50 concurrent connections equals 50,000 visits month, 750 nearing 1000000 visitors.

most developers vastly overestimate number of concurrent users have. info point, web sites operate comfortably on "free" firebase plan days. in fact, more 99.5% of of firebases never nail 50 concurrent limit.

so, long story short, 10k concurrents more plenty our self-serve customers , 1 time you've approached 12 1000000 users, well, enterprise alternative appealing point.
