Volumes · $0.15/mo (1 GB NVMe)
Fly.io Volumes at $0.15/GB/mo is significantly more expensive than object storage tiers from Azure, Google Cloud, Oracle, OVHcloud, and Scaleway, all priced at $0.01/GB/mo. However, Fly.io offers NVMe-backed block storage with lower latency, whereas the cheaper alternatives are object storage with retrieval fees and minimum retention periods. For true block/persistent volume workloads, OVHcloud and Kamatera offer NVMe or SSD block storage at $0.05/GB/mo, making them 3x cheaper than Fly.io while maintaining performance.
NVMe SSD block storage at $0.05/GB/mo with 20,000 IOPS included, matching Fly.io's performance tier at one-third the price.
Caveat: Windows/SQL licensing and managed services add hidden costs; powered-off servers may continue accruing charges; billed by the minute.
| Provider | Plan | Price | Specs | |
|---|---|---|---|---|
| Microsoft Azure | Blob Storage · Cool tier | $0.01/mo | Per GB/month, LRS. Lower storage cost, retrieval and early-deletion fees apply for objects deleted before 30 days. | Visit |
| Google Cloud | Cloud Storage · Nearline storage | $0.01/mo | $0.010/GB/month, 30-day minimum storage duration, $0.01/GB retrieval fee | Visit |
| Oracle Cloud Infrastructure | Object Storage · Infrequent Access | $0.01/mo |
Block storage at $0.05/GB/mo with 500+ IOPS, providing persistent volume semantics at one-third Fly.io's cost.
Caveat: IPv4 addresses billed separately; Windows license surcharge applies; APAC egress loses free status after mid-2026.
Block storage at $0.05/GB/mo with 1,100 static IOPS and 200 MB/s throughput, though HDD-based rather than NVMe.
Caveat: Intro pricing is promotional; renewal rates are 2-6x higher; outbound data transfer beyond 2TB pooled free tier is tiered at $0.036-0.018/GB.
Object storage at $0.01/GB/mo is 15x cheaper than Fly.io for archival or infrequent-access workloads.
Caveat: Retrieval and early-deletion fees apply for objects deleted before 30 days; minimum 128 KiB per object; not suitable for real-time persistent volumes.
Object storage at $0.01/GB/mo with 30-day minimum duration and $0.01/GB retrieval fee, ideal for warm archival at 15x lower base cost.
Caveat: Retrieval fees and 30-day minimum storage duration make this unsuitable for active persistent volumes; network egress billed above 200 GiB/month free tier.
