Fly.io

Fly.io transforms containers into Firecracker MicroVMs running on bare metal across the globe. It is essentially a "CDN for your backend".

When to Use

• Global Edge Microservices & APIs: Deploying full-stack applications and databases physically close to users.
• Modern Full-Stack Frameworks: Next.js, Remix, Phoenix LiveView, Rails, and Node.js with instant global scaling.
• LiteFS Distributed SQLite: Replicating SQLite databases globally with low-latency local reads and streaming primary writes.
• GPU Inference at the Edge: Running open-weight AI models on edge GPUs with rapid cold starts.
