About Fly.io

Fly.io brings containers to the edge, running your applications in data centers closest to your users for minimal latency. Deploy full-stack applications including databases with automatic global distribution. Unlike traditional serverless, Fly runs real VMs with persistent volumes, giving you more control while maintaining simplicity. The 2024 pay-as-you-go pricing means you only pay for actual compute and storage used. With features like autostop/autostart and regional scaling, Fly excels at globally distributed applications. Perfect for teams migrating from Heroku or needing more control than serverless platforms offer.
