If you're an AI developer or data scientist looking for a secure infrastructure to run AI-generated code, Daytona is the clear choice. Its fast sandbox creation and support for multiple programming languages make it ideal for your needs, especially if you value isolated execution for security. However, if you require mobile app support or prefer open-source solutions, you should look elsewhere.
On the other hand, if you’re a solo developer focused on building latency-sensitive applications, Fly.io is the better option. Its ability to deploy across multiple regions ensures low latency for your users, and the scale-to-zero feature helps manage costs effectively. Just be prepared for usage-based billing and a steeper learning curve if you lack extensive operational knowledge. Avoid Fly.io if you prefer a more predictable billing structure and minimal operational overhead.
