Should I let deployed server sleep and how does pricing work?

How it works

Our pricing is designed to let you launch a small application for free, and scale costs affordably as your needs grow.

Fly.io services are billed per organization. Billing is based on the resources provisioned for your apps, pro-rated for the time they are provisioned.

Plans

All plans require a credit card. Each organization starts on the Hobby plan, which is a straightforward pay-as-you-go option.

We don’t offer a “free tier.” Instead, we offer some free resource allowances that apply to all plans, including the Hobby plan, and includes enough usage per month to run a small full-stack app, full-time, for free.

If you want to scale beyond the included free resources, you can pay for just what you need at the usage-based pricing listed below.

Your organization might be limited to prevent abuse or help with capacity planning.

If you need more support or compliance options, you can choose one of our paid plans. These come with usage included and additional support options. In some circumstances, you may need an organization and a paid plan to get full access.
