The Verdict
Coolify is built for indie hackers and small teams, with a focus on git-deployments and database-management. Fly.io targets full stack developers and global apps and leads with global-deployment and firecracker-vms.
On pricing, Fly.io is the clear winner for budget-conscious users — starting at $0/mo compared to $5/mo for Coolify. That $5/mo difference adds up quickly for growing teams.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Bottom line: Coolify has a slight overall edge — but if deploy apps globally to 30+ regions easily matters most to you, Fly.io may still be the right call.
