Fly.io's Unexpected Robot Boom: A Cloud Platform's Unexpected User Base

Fly.io, a developer-focused public cloud, initially prioritized developer experience (DX). However, in recent months, they've discovered that their platform's growth is primarily driven by robots, not humans. These robots utilize Fly.io's compute resources for "vibe coding," a vector-based code generation process. Their needs – quick start times, flexible virtual machines (Fly Machines), and easy storage and networking – unexpectedly align well with Fly.io's design. Fly.io found that features like rapid VM start/stop, incremental storage, and MCP protocol support are unexpectedly robot-friendly. While not initially designed for robots, Fly.io recognizes the need to focus on robot experience (RX) and is adapting to better serve this new user base.
