It's designed for apps that need to be close to users — deploy a container image and Fly distributes it to the regions you specify.\n\nFor agent developers building real-time interfaces (chat, voice, streaming), Fly's global distribution reduces latency between the user and the agent backend. It supports any language and runtime via Docker, with first-class support for Elixir, Go, and Python. The tradeoff is a steeper setup curve compared to platforms like Railway or Vercel."}
