Unexpected Charges on Pay-as-You-Go Accounts

critical overage

Multiple users report being charged unexpectedly while believing they were on a free plan. Fly.io's Pay-as-You-Go model includes free resource allowances, but charges appear when those thresholds are exceeded — sometimes without clear warnings. Reports document charges ranging from $25 to $747 appearing without user-initiated activity.

"Confirm your payment method to keep using our platform" then proceeds to charge me money when i am using the free plan. This is a scam.

trustpilot

In july 19, suddenly I got a mail from bank. Fly.io tried to deduct 25$. I instantly sent a mail to there support mail. They said I was activated Prepared Credit! But I never do it. Today I get another mail, they try to charge 747$. After july I don't log into fly.io and my deploy was failed those time. Now when I login after seen this mail. I'm surprise! 22 days ago a project was deployed! But I do not deploy anything. Please stay safe. Never trust fly.io for billing issues. They will suddenly charge from your card. They have various excuse.

5

Paid Dedicated IP Added to Accounts Without Consent

high addon

Fly.io has been reported to unilaterally add a paid dedicated IP option to accounts — including free accounts — and charge users who never requested the feature. A separate period saw them change defaults from dedicated to shared IP addresses, breaking existing deployments.

Scammers. They unilaterally added a paid dedicated IP option to all free accounts, even for those who absolutely didn’t need it, and charged the money from the card without consent.

Other customers are complaining that they changed defaults from dedicated to shared IP addresses, breaking their deployments and losing them business.

6

Database Cluster Charges When Idle or Abandoned

medium overage

Provisioned database clusters continue to accrue charges even when not actively used. Users who set up a database cluster during an abandoned onboarding attempt later discovered recurring billing for clusters with zero operations.

trustpilot

I signed up and tried to set up an app. My attempts were not successful. I never successfully deployed an app once. Yet I was being charged for database clusters that were not getting any operations on them. I had an abandoned attempt to use them and gave up only to have multiple charge attempts.

7

Higher Bandwidth Costs in India and APAC Regions

medium overage

Outbound data transfer is significantly more expensive in India and APAC. India receives only 30GB free per month versus 100GB in North America/Europe, and pays $0.12/GB after the free threshold versus $0.02/GB in NA/EU — six times higher per GB.

North America Europe 100GB per month free $0.02 per GB India 30 GB per month free $0.12 per GB How come India is so much more expensive?

Post-Cancellation Email Support Charges

low support

At least one user was charged $29 for email support after canceling their account and deleting it — for support they did not request. The charge appeared two days after account deletion.

trustpilot

I subscribed to this service to deploy my Remix app and paid $15 for half a month of support. Unfortunately, the support I received was ineffective, so I canceled my subscription and deleted my account. However, two days later, I was charged an additional $29 for email support that I didn’t request. In total, I’ve spent $45-46 and wasted three days trying to deploy my app with no useful assistance.
