I just created an account and deployed a node.js app following the tutorial in Run a Node App · Fly Docs. For now I am just testing fly.io to see if I will host my server here, so I would to see how it goes before paying.
Now I just realized that in my dashboard there are two apps. One has a tag under it saying
Free builder. But the app that I launched using the tutorial does not have it. I wonder if I will have to pay something for my new created app?
I would appreciate if someone could confirm this other app will still be free or not! Thanks a lot!
You’re in the free tier still!
The 2nd app is a remote Docker builder, which:
- is free
- runs the “docker build” step for you when deploying, so you don’t need Docker running locally
Also, does this VM count towards the 3 VMs of the free tier?
The Docker builder does NOT count towards the 3 VM’s on the free tier!
Thanks for this information. Just for confirmation, if we have:
- 1 main application with scale count of 2
- 1 postgres db app
- 1 builder
This remains free in terms of VM (as soon as storage and bandwidth are OK)?
Hello @sebbelese, this depends on how many instances your Postgres db has (and of course the size of each VM). But it’s true: the builder does NOT count as one of your billable VMs.
The free allowances are specified here: Fly App Pricing · Fly Docs
We do recommend always running at least 2 instances in a database cluster for availability purposes on a production app.
