  • They diverge on capability: Coder covers Self-hosted workspaces, Fly.io covers Global deployment.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Coder

  • Premium plan pricing is not published and requires contacting sales.
  • Requires self-hosting and managing the underlying infrastructure, unlike fully managed cloud IDEs.
  • High availability, audit logging, and RBAC are gated behind the paid Premium tier, so the free Community edition lacks enterprise controls.

Fly.io

  • Egress is priced by destination region, from $0.02 per GB in North America and Europe to $0.12 per GB for Africa and India, so the same traffic costs six times more depending on where users are
  • Stopped machines still bill at $0.15 per GB of root filesystem a month, so a paused service is not a free one
  • Volumes are billed on provisioned capacity rather than usage, at $0.15 per GB a month
  • Reservation discounts of 40% require paying a year up front, from $36 to $1,440
  • Fly Kubernetes is a separate $75 a month per cluster
  • Dedicated IPv4 addresses are $2 a month each
