Fly.io Pricing 2026

Fly.io uses pay-as-you-go pricing with no fixed monthly plan required. A single always-on shared-CPU VM with 256 MB RAM costs approximately $1.94/month. A realistic single-app production setup (one 1 CPU/1 GB VM + 10 GB volume + dedicated IPv4) runs roughly $10–$20/month. Multi-region or database-heavy deployments typically cost $50–$300/month. Optional support plans start at $29/month.

Fly.io does not have a permanent free tier as of 2024. New accounts receive a free trial of 2 VM hours or 7 days (whichever expires first). After that, a credit card is required and all usage is billed. Legacy customers who signed up before October 2024 may retain old Hobby plan allowances (3 shared-CPU VMs, 160 GB transfer), but these plans are no longer available to new users.

The main surprise costs are: (1) dedicated IPv4 addresses at $2/month per app — required for many setups; (2) persistent volumes billed on provisioned size whether the machine is running or not; (3) egress bandwidth at $0.02/GB, which adds up quickly for media or data-sync apps; (4) inter-region private networking now billed at machine rates as of February 2026; and (5) volume snapshot billing starting January 2026. Multi-region architectures multiply all of these costs.

Fly.io does not have a traditional enterprise sales process or negotiated contracts — pricing is set by published rates and scales automatically with usage. For high-volume workloads, volume discounts may be available by contacting their team directly. The most effective cost control is architectural: suspending machines when idle, right-sizing RAM/CPU, and using shared-CPU instances for low-traffic apps instead of dedicated-CPU machines.

Fly.io does not offer annual prepay discounts. All billing is month-to-month, charged per second of resource usage. There is no annual commitment option or upfront payment path. Cost optimization comes from machine suspend/resume automation and right-sizing, not from contract terms.

Fly.io is generally cheaper for compute-intensive or multi-region workloads where you want fine-grained control, but has a steeper learning curve. Railway and Render offer simpler fixed monthly pricing tiers (Railway from $5/month, Render from $7/month) that are more predictable for small apps. Fly.io's pay-as-you-go model wins at scale but can surprise developers who leave machines running or forget to provision minimum resources. For a basic single-app deployment, all three cost roughly $5–$20/month.

Fly.io's Managed Postgres pricing is separate from compute costs and starts with a Basic single-node cluster. Production clusters with multiple nodes range from low to high double-digits per month for compute, plus $0.28/GB/month on provisioned storage. Performance-tier clusters with larger RAM configurations cost significantly more. Database storage is billed regardless of whether the cluster is active, so deprovisioning unused databases is important for cost control.
