“Global deployment is its strength. For edge-first architectures, Fly.io solves distribution better than anyone.”
“Datadog's land-and-expand across security, CI, and database monitoring makes them the observability platform to beat.”
“Apps running close to users is the future. Fly.io's Machines API enables new categories of distributed applications.”
