Strengths

  • •Built-in reverse proxy removes need for separate Traefik or Nginx.
  • •Sub-500ms cold boot times with automatic IPAM and TAP interface management.
Weaknesses
  • •Wake-on-request scaling marked WIP; core feature not yet shipped.
  • •Fly.io already provides this as a managed service with more maturity.
