Fly.io is a global application deployment platform — providing lightweight, fast-booting VMs distributed across 30+ regions worldwide for applications that need to run close to users globally. Fly.io's architecture differs from traditional PaaS — deploying Docker containers as Firecracker microVMs with near-instant startup, enabling global deployment with fast cold starts unavailable in traditional serverless environments. AI workload support is a growing Fly.io use case — GPU machines for model inference and AI applications that need global distribution for low-latency AI responses. Regional routing automatically directs user traffic to the nearest Fly.io machine — applications deployed in multiple regions automatically receive traffic from the geographically closest region. Fly Machines are the deployable unit — individual Firecracker microVMs that can be spun up on demand, suspended when idle, and restored in under a second for cost-effective API and job workloads. Volumes provide persistent storage for stateful applications — databases and file systems that persist across machine restarts. Private Networking enables secure inter-service communication across Fly.io deployments — services communicate through WireGuard encrypted private networks. Postgres on Fly deploys managed PostgreSQL clusters — a native database option for applications deployed on Fly. With developer adoption for globally distributed applications, WebSocket-heavy apps, and AI inference services, Fly.io validates for latency-sensitive distributed application deployment.
Fly.io AI runs as llm assistant software built around code and data workflows. Users typically start with a prompt, upload, or connected data source, and the underlying model handles the heavy lifting before returning a result you can refine or export. It's available on cli, web, and api.
The capabilities that matter most for teams evaluating Fly.io AI.
Near-instant startup lightweight VMs enabling cost-effective on-demand compute — global deployment without traditional VM cold start latency.
Automatic traffic direction to the nearest region across 30+ global locations — minimising application latency for globally distributed user bases.
GPU compute on global Fly.io infrastructure for AI inference — low-latency model serving with global distribution for AI-powered applications.
