The ZERO dollar mobile app that scales (frontend + backend + database)

... if it sounds too good to be true...
But it is, in the article I've placed links to all the official resources so you can check on your own.
teehee! there's always a cost... if not now, later.
Yup, did the same --
with Flutter I've build Android+iOS apps,
with Firebase and JavaScript I've setup backend and it's functions,
with Vue.JS I've build simple web app and
with Ghost I've setup a blog.
It's super easy to be one-man-army nowadays.
Yes, a serverless architecture will become the standard. Even for "quick & dirty" MVPs. Why bother now developing a monolith (that I upload as a Docker to the cloud) when I can simply expose serverless functions. The tools are becoming more simple & accessible.
I'm testing with Zappa for Python which is something like a "one stop shop deploy from CLI with one command" tool for AWS. MongoDB allows also free-usage (upto 5GB) of their cloud service Atlas.
Congrats to your user base.
Thank you!
It sounds like a very interesting article, I'll read it to me during my lunch break
Hi everyone, I thought I'd share the tech stack that allowed me to scale to more than 20k daily active users for my mobile apps and that starts completely for free.
If you questions just ask :)
Nice article, but I'm curious why you wrote that serving 25000 active daily users is now costing you $300 monthly.
That sounds expensive to me.
Well to me it actually seems cheap: 100$ for the db (so I never have to worry about it slowing down even of all the users are online), 50$ for the cache (to be fast), 50$ for metrics/insights and the rest for the serverless functions that are always with a response time below 100ms.
All considered I think it's hard to find a better deals for the same price.
That's the serverless trap, starts out cheap and then as they grow, get's expensive. What if he get's 1million DAU, the cost will now be > $300 * 40 = $12,000. That means end of business.
It actually isn't that linear. Much of the cost is from the db, which doesn't need to scale linearly and from the metrics, which you can reduce when you have an high volume.
Having said that with 1 million DAU, thee revenue will scale too, and I would be pretty happy if it did!
