Fly.io

Fly.io is a cloud platform that provides hardware-virtualized containers (Fly Machines) to run full-stack applications and code execution sandboxes globally, close to users. It is designed for real-time and latency-sensitive use cases, including MCP (Model Context Protocol) server deployments.

Features

• Global Edge Deployments: Run containers in 35 regions worldwide on Fly.io's custom-built global cloud.
• Hardware-Virtualized Containers (Fly Machines): Containers are hardware-isolated (KVM) and can run any Docker image.
• Fast Boot and Scalability: Launches containers in milliseconds and supports scaling to thousands of machines.
• Auto-Scaling and Scale to Zero: Machines automatically scale to zero when idle, so you only pay for active usage.
• User-Specific Routing: Dynamic request routing allows each user or process to access their own sandboxed environment.
• Persistent Storage: Provides dedicated storage options via Fly Volumes, Fly Managed Postgres, and S3-compatible Tigris Data.
• REST API Access: Full control of Fly Machines via a REST API.
• Server-Sent Events (SSE) Support: Enables integration of sandboxes into LLM workflows using SSE.
• Framework Support: CLI can generate containers for popular frameworks (Rails, Phoenix, Django, Node, Laravel, .NET) even without a Dockerfile.
• Secure by Default: Memory-safe stack, hardware isolation, and direct deployment on Fly.io's own metal.
