Reviewer scorecard
“Deploy Deno apps globally with zero config. The built-in KV store and BroadcastChannel are useful primitives.”
“Run any Docker container globally with `fly launch`. The Machines API for programmatic VM creation is uniquely powerful.”
“Simple and effective for Deno projects. The free tier is generous for side projects and experiments.”
“Global deployment is its strength. For edge-first architectures, Fly.io solves distribution better than anyone.”
“Deno Deploy proves the tight runtime + platform integration creates the best DX. Bun will follow this pattern.”
“Apps running close to users is the future. Fly.io's Machines API enables new categories of distributed applications.”
