Fly.io introduces Sprites, persistent sandbox environments that launch in about one second and let developers install software, create checkpoints, and restore environments. Unlike ephemeral sandboxes, Sprites remain available across sessions and hibernate when inactive.
Fly.io discusses the Model Context Protocol (MCP), examining its promise and limitations for building AI-powered applications. The team offers a critical technical perspective on MCP’s place in the broader ecosystem of AI agent development and infrastructure.
Thomas Ptacek of Fly.io argues that building an LLM agent is an unusually accessible programming experience and encourages developers to try it themselves. The article walks through a simple Python agent and says hands-on experimentation helps developers form informed opinions; its case centers on how easy it is to get an agent running, rather than the scale of its capabilities.
