Love at First Sprite? (davidedmiston.com)

Fly.io has announced a new feature called Sprites, which provides developers with cheap, statefully sandboxed environments equipped with a suite of agentic coding tools, including Codex and Claude Code. This innovation allows users to run AI-based coding agents in a secure space where they can work without the fear of compromising local systems. The sandbox supports strong checkpointing, enabling quick rollbacks if the AI behaves unexpectedly, thus protecting the user's local data and resources. This offering is significant for the AI/ML community as it simplifies the process of building and deploying machine learning applications by allowing for lightweight, remote coding environments. Developers can create and manage instances effortlessly, with costs remaining low—approximately $0.46 for a 4-hour coding session and around $4 monthly for a typical lightweight web application. While Sprites has some minor bugs, its potential to streamline the development process and enable innovation at low costs makes it an exciting development in the landscape of AI tools and environments.
