Fly.io Overview

Fly.io is an edge application platform that runs apps as lightweight Firecracker micro-VMs across a global network. It emphasizes Dockerfile-first deployments and a powerful CLI (`flyctl`) for fast, scriptable workflows. Fly.io provides Anycast networking, global routing, per-region scaling, and scale-to-zero for idle workloads, making it a strong fit for latency-sensitive apps and globally distributed teams.

DigitalOcean Overview

DigitalOcean App Platform is a fully managed PaaS that provides a fast path from Git to production. It automates builds, deploys web services, background workers, and static sites, and integrates with DigitalOcean-managed databases. The platform prioritizes simplicity and a UI-first workflow with tier-based pricing, making it ideal for teams that want a turnkey deployment experience without managing infrastructure.
