One of my favorite features of Nostr is that I don't need to get permission from some central authority to develop stuff to use it.

I don't need an API Key to retrieve events.

I don't need to register my name or a phone number with a central authority.

I don't need to buy X amount of credits or sign up for a 7-day trial.

With a constrained budget in traditional systems a paywall stops me in my tracks. But with Nostr, things are either no cost, or I can pay with lightning. Can't stress enough how micropayments help

I can write some code, try stuff out, make changes, try some more and eventually get to a point where I find it useful enough

Where possible, I do all my testing in production.

I hope Nostr is opening up possibilities for others as well.
