Code And Let Live

Fly.io argues that ephemeral, read-only sandboxes are obsolete for AI agents and introduces Sprites: durable, stateful Linux environments that boot in 1-2 seconds, auto-sleep when idle, support instant checkpointing, and persist indefinitely. Unlike traditional containers, Sprites provide agents with actual computers that maintain state between sessions, eliminating the need to rebuild environments or work around containerization. The piece contends that AI agents like Claude work better with persistent storage and long-lived environments, enabling use cases from iterative development to production apps that evolve over time without traditional deployment cycles.
