Disclosure: I'm building https://proxylity.com, but I'm seeking to understand here, not to promote it.
The fixed cost per region seems like a barrier to experimenters and large development teams alike. It's not much in the grand scheme, but enough to prohibit an individual from standing something up on a whim and leaving it around. Likewise, for large development teams having a stack for every developer would be costly. In each case I'm not talking about "production" workload, but the semi-idle stacks that run for long periods, are critical, need to reflect the production setup, and don't generate revenue.
Your LBs are quick to deploy, which is super important for fluid CI/CD experience but they miss the mark without being usage based.
Do others see this the same way?
Yeah, honestly we didn't want to go with the IaaS/cloudflare style pricing model, we give you full fly.io nodes and control of them and forward the cost. Keeps things simple and without the tricks. I can see what you're saying though
