I've noticed that a lot of paid dev tools are just priced too high or that I run the risk of blowing my budget depending on scale. I wish more paid dev tools were aware that I don't actually know my usage up-front, and that I'm scared of potentially ending up with a ridiculous bill if I overlook something.

I totally get that it's on me, but things [like this](https://hackernoon.com/how-we-spent-30k-usd-in-firebase-in-l...) happen, and I'm way more apprehensive of services that make that a possibility. E.g. I'd love to use Auth0 for everything, but the risk of spending way too much on something I can roll myself is always on my mind.
