They offer scalability across different regions and provide the networking and tooling for it. Their service also has a way to go, but I see continuous progress.
What has kept me from trying fly.io is that you need to sign up with a credit card before trying out the service. So when evaluating a bunch of options for a company, I ignored fly because I'd either need to use the company card (a hassle) or use my own card (another hassle especially if having to deal with expenses). Yes it was supposedly "free tier" but there was no indication of whether it was possible, even accidentally, to exceed the free tier - for example leaving a forgotten app running. Gave me bad AWS vibes.
All the other services (heroku, render, railway) let me try out at least a toy app without having to use a card. That allowed me to evaluate whether the service was compatible with our needs without any further commitment.
This is bizarre. I spent a good 5+ min looking over the README and documentation site, and couldn’t find out what that project is other than “a backend that runs on Nodejs.” Yeah ok but what is it? Why am I interested? I’m not looking to be sold, just for it to tell me what it’s for. I have some assumptions based on how I got linked there, but this is surprising to me.
In a nutshell a place for your web page or mobile app to store and retrieve data. There is some auth, business logic / security stuff but not as much as you get in an MVC web app. Let’s you build apps where a lot of the work happens on the front end and the back end is basically a place to save to disk.
Parse was a startup but they shut down and open sourced their code.
