The short answer
A FLY.IO* CLOUD charge is a monthly application hosting and micro-VM infrastructure fee from Fly.io, Inc. for deploying global containers.
Why it shows up like this
A transaction listed as FLY.IO* CLOUD is a monthly cloud computing and application hosting charge from Fly.io, Inc. Fly.io is a public cloud developer platform that packages Docker containers and runs them as fast micro-virtual machines deployed globally near end users. The descriptor typically shows on banking records as FLY.IO* CLOUD, FLY IO INC, FLY.IO BILLING, or FLYIO CLOUD, representing Fly.io Application Edge Hosting fees across their international edge server network.
This charge appears on your statement on the first day of the month when your organization incurs usage that exceeds Fly.io free resource allowances. Unlike flat-rate shared web hosts, cloud hosting platforms like DigitalOcean or Linode bill for fractional infrastructure consumption. On Fly.io, charges accumulate based on CPU core runtime, RAM allocations, persistent NVMe storage volumes, dedicated IPv4 addresses ($2 monthly per address), and outbound network data transfer. A side project, automated webhook bot, or staging database left running will accrue monthly infrastructure fees.
To check your account details, log in to fly.io/dashboard and select your organization to view active applications and past invoices. You can inspect the breakdown of compute hours, bandwidth, and attached persistent volumes. If you no longer need the hosted project, delete running applications from the dashboard or execute the command 'fly apps destroy' in your terminal. Deleting inactive resources and releasing dedicated IP addresses halts all ongoing monthly billing immediately.
Don’t recognize it? Common scenarios
Developers frequently deploy small test bots or staging servers that quietly run in the background after initial testing finishes. Even when an application handles no web traffic, attached persistent storage disks and dedicated IPv4 addresses generate monthly charges.
- A developer deployed a small side project, bot, or web service using the Fly CLI (`flyctl`).
- Dedicated IPv4 addresses ($2/mo each) or persistent volumes remained attached to an organization.
- Outbound network egress exceeded the baseline free resource allowances.
How to locate the invoice and cancel
- Open the Fly.io Dashboard Log in to fly.io/dashboard.
- Inspect Organizations and Invoices Click on your organization name and select Billing to review monthly usage.
- Destroy Apps or Volumes Use the dashboard or run `fly apps destroy <app-name>` in the terminal to remove fee-generating resources.
Frequently Asked Questions
Why was I charged a small amount like $2 or $5 on Fly.io?
Dedicated public IPv4 addresses cost $2 per month, and small micro-VM compute instances incur modest usage fees once free credits are consumed.
How do I release dedicated IP addresses on Fly.io?
Run `fly ips release <ip-address>` or remove them from the app IP management tab in the web console.
