Overview
Fly.io is a platform for running full-stack applications close to users by distributing them across edge locations worldwide. It transforms containers into micro-VMs that run on physical servers in datacenters around the world. What makes Fly.io unique is its focus on geographic distribution - deploy your app globally and Fly automatically routes users to the nearest instance. The platform supports Postgres, Redis, and other databases with automatic replication across regions. Fly's anycast network means your app has a single global IP address while running in multiple locations. With features like instant deployment, auto-scaling, built-in load balancing, and persistent volumes, it handles both stateless and stateful workloads. The platform offers a generous free tier and simple pricing based on resources used. Perfect for applications requiring global low-latency, multi-region databases, or edge computing. Popular for deploying Phoenix (Elixir), Rails, and other full-stack frameworks that benefit from running close to users.
