Where Does Fly.io Store Apps and State?
Where Fly.io keeps apps in cloud plus CLI state on Windows and computers. Exact folders are covered below.
Last updated
Fly.io runs apps on worldwide hardware with device CLIs. Your account holds organizations, apps, and volumes. Computers hold login, flyctl state, and WireGuard keys.
Same login plus org means same apps. Exact state names shift with flyctl releases. Keep online during deploys so releases upload. If apps vanish, check the org picker first. A personal versus client org split is the usual empty dashboard cause with hosting CLIs. Screenshots of settings help when support asks for reproduction steps later.

Frequently asked questions
How do I move Fly.io apps to a new device?
Sign in on the new device with the same email and orgs return from the cloud. Devices hold login plus flyctl state and wireguard keys. Configs read from fly.toml in repos. Check the org before wiping, since a second email shows empty.
Does Fly.io keep release history?
Yes, in Fly.io cloud with full release history per app. Devices hold a working copy plus flyctl state. Views rebuild after sign in. Keep fly.toml files in version control for records, since devices never hold the master infra alone.
