To be blunt, my experience is that you shouldn’t be trusting them as your host to begin with. We moved our app off Fly to AWS Fargate earlier this year. We were so tired of Fly incidents causing issues for our customers. We wasted so much time debugging intermittent cluster issues. Their Redis integration with Upstash has severe performance regressions on a regular basis. Fly is fine for to get started or for your hobby app. It’s not fit for heavy production use.

My experience with them taught me a very valuable lesson. The real value AWS provides is rock solid networking. Everything Just Works. And, as the article pointed out, tell your LLM of choice to write some IaC to spin up your environment. The barrier to entry is mostly gone. The PaaS moat has mostly been filled in.

Now, all that being said, I’m going to go try sprites as a hosting option for low effort, unimportant, vibe coded internal tooling.
