Fly.io is a developer-focused public cloud platform designed for deploying and running applications. It uses hardware-virtualized containers, called Fly Machines, which are built on a memory-safe stack and run on the company's own hardware across 18+ regions.
The platform is designed for software companies and developers who need to scale applications globally. It provides tools such as Sprites for running untrusted or AI-generated code in isolated sandboxes, as well as managed PostgreSQL services.
Buyers should note that the platform uses a usage-based pricing model, charging for CPU and memory per second. Options are available for those with specific regulatory needs, including HIPAA compliance and SOC2 Type 2 attestation.
Before choosing Fly.io, buyers should confirm if the pay-as-you-go model aligns with their budget and if the CLI-based deployment workflow fits their existing CI/CD pipeline.
