Reviewer scorecard
“Heroku DX on your own infrastructure. Docker-based deploys, SSL, and monitoring without cloud vendor lock-in.”
“Run any Docker container globally with `fly launch`. The Machines API for programmatic VM creation is uniquely powerful.”
“If you want control over your infrastructure without raw Docker/K8s complexity, Coolify is the sweet spot.”
“Global deployment is its strength. For edge-first architectures, Fly.io solves distribution better than anyone.”
“The self-hosting movement is growing. Coolify makes it accessible to developers who don't want to be sysadmins.”
“Apps running close to users is the future. Fly.io's Machines API enables new categories of distributed applications.”
