For a solo developer focused on low-latency applications, Fly.io is the clear choice. Its true multi-region deploys and scale-to-zero machines help optimize performance and manage costs effectively. However, be aware that the usage-based billing might lead to unpredictability in costs, and you'll need some operational knowledge to manage the infrastructure.
On the other hand, if you're part of a team looking for an open-source, highly customizable solution for AI-driven development, OpenHands is ideal. It allows for automation and collaborative coding, making it suitable for developers who are comfortable with technical setups. Just keep in mind that if you're looking for a straightforward, out-of-the-box experience, you might find it challenging without prior coding expertise.
