Fly.io doesn’t have a free tier, but if your monthly bill comes to less than $5, we waive it. This page explains how the waiver works and who gets it.

How the waiver works

If your personal organization’s bill for the month is under $5, you don’t pay it. If it’s $5 or more, you pay the full amount. For example:
  • A $4.20 bill is waived, so you pay $0.
  • A $7.00 bill isn’t waived, so you pay $7.00. The first $5 isn’t taken off.
All usage counts toward the bill, including Machines, Sprites, Managed Postgres, volumes and data transfer.

Who gets the waiver

The waiver applies to your personal organization, the one we create when you sign up. It needs to be on Pay As You Go billing with a credit card on file. You don’t need to sign up for it. Other organizations you create or join don’t get the waiver, so their bills are charged in full.

How it fits with the free trial

New accounts start with a free trial: $1 of credit, with no credit card required. The waiver starts after you add a credit card.
  1. Before you add a card: you use the $1 trial credit, with trial limits.
  2. After you add a card: the trial limits are lifted, and any month that comes to less than $5 is waived.

What fits under $5 a month

A small app can stay under $5. The cheapest always-on app is a shared-cpu-1x Machine with 256MB of RAM in Ashburn (iad) or Secaucus (ewr). It costs $2.19 per 30 days of continuous runtime, plus any outbound data transfer. Machines that stop when idle only cost compute while they run, which helps keep a side project under $5.
