S3 Alternatives for Object Storage: What You're Actually Paying (and What You Could Be Paying Instead)

I've been in IT for thirty years. I've watched storage costs go from "buy a SAN and cry" to "it's just pennies per gigabyte." And somehow, in 2026, developers are still getting absolutely hammered on object storage bills, mostly because they signed up for S3 in 2019, never looked at the invoice line items, and assumed AWS was just the price of doing business.

It's not. Not anymore.

The problem with S3 isn't the storage rate. It's egress. It's the fact that Amazon charges you to take your own data out of their infrastructure. It's the layered request pricing, the 12-month-only free tier that vanishes before most side projects get traction, and the general opacity of a pricing page that requires a calculator, a spreadsheet, and a strong coffee to parse.

This article is for developers and DevOps engineers who are already on S3 and have a nagging feeling they're overpaying. I'm going to run a real cost scenario through four providers, tell you who wins each use case, and give you my actual opinion, not a diplomatic "it depends."

The Benchmark Workload

To keep this grounded, I'm running each provider through the same scenario: 100 GB stored, 100 GB egress per month. This is a realistic starting point for a small SaaS app, a portfolio site with assets, or a dev team running staging environments. It's not enterprise scale, but it's where most of these decisions get made, before you're big enough to negotiate an enterprise deal.

AWS S3: The Default You're Probably Already Paying

S3 is the reference implementation. S3-compatible APIs are now the standard that every competitor benchmarks against. None of that means you should keep paying for it without thinking.

In US East (N. Virginia), S3 Standard storage runs $0.023 per GB per month. For 100 GB, that's $2.30 in storage. Reasonable. Then you transfer 100 GB out. The first 100 GB per month is free across all AWS services combined, so this specific workload just barely clears the free egress threshold. In practice, if you're also running EC2, RDS, or anything else, that 100 GB free allowance is already eaten. Past that threshold, you're paying $0.09 per GB. Ten cents a gigabyte to move your own data. Once you cross into real traffic, say 1 TB out per month, that's $90 just in egress, plus $23 in storage, plus request fees on top.

Benchmark cost (100 GB stored, 100 GB egress): ~$2.30 storage + $0 egress (if within free tier) = ~$2.30/month best case, $11.30/month if free egress is already consumed.

Best for: Teams already deep in the AWS ecosystem where data stays within AWS services, and enterprises with negotiated pricing. If your data never leaves AWS, the egress problem mostly disappears.

Avoid if: You're serving assets directly to end users and paying full egress rates. That math turns ugly fast.

DigitalOcean Spaces: Flat-Rate Simplicity for Developer Teams

Spaces is a flat $5 per month subscription. That gets you 250 GiB of storage and 1,024 GiB of outbound transfer. No per-request fees. CDN included. The pricing model is refreshingly simple, and if you're already running Droplets on DigitalOcean, this is the most frictionless path off S3 you'll find.

For our benchmark workload, 100 GB storage and 100 GB egress both fall well within the included limits. Your bill is $5.00, full stop. Traffic between Spaces and Droplets in the same datacenter region uses the internal network and doesn't touch your transfer allowance at all. That's a real advantage for teams running their app servers on DigitalOcean.

The catch is the floor. If you're storing 10 GB and moving 5 GB out per month, you're still paying $5. The effective per-GB rate at low utilization is poor. Spaces rewards teams that actually use most of what's included. Overage rates, when you get there, are fair: $0.02 per GiB for additional storage, $0.01 per GiB for additional transfer.

One hard limit: 5 GB maximum object size. Large video files, database dumps, and ML model checkpoints won't fit. Know that going in.

Benchmark cost (100 GB stored, 100 GB egress): $5.00/month flat.

Best for: Developer teams already on DigitalOcean who want predictable billing and consistent utilization. The CDN inclusion and internal transfer pricing make this a good stack if you're already in their ecosystem.

Try DigitalOcean Spaces: New accounts receive $200 in credit over 60 days, enough to evaluate Spaces alongside your existing S3 workload at no cost.

Vultr Object Storage: Flat Plans at Scale, Not at Small Sizes

Vultr's approach mirrors DigitalOcean's in structure but differs in pricing floor. The Standard tier is $18 per month and includes 1,000 GB of storage and 1,000 GB of egress. No per-request charges. The math only works in your favor when you're actually filling that 1 TB bucket.

For our 100 GB benchmark, you're paying $18 for capacity you're mostly not using. The effective per-GB storage rate on the Standard tier at full utilization is $0.018, which is competitive with S3. At 100 GB stored, your effective rate is $0.18 per GB. That's the worst per-GB rate on this list at small scale.

Scale it up, though, and Vultr gets interesting. If you're regularly pushing 800 GB to 1 TB of storage with comparable egress, the flat-rate predictability has real value, and the $0.01 per GB overage egress rate is among the lowest available once you're past the included allowance.

Same object size limitation as Spaces: 5 GB maximum. Large file storage is off the table.

Benchmark cost (100 GB stored, 100 GB egress): $18.00/month.

Best for: Workloads running close to or above 1 TB of storage per month, where flat-rate pricing beats the anxiety of a variable bill. Not the right fit for small or early-stage workloads.

Try Vultr Object Storage: New accounts receive $300 in credit, which gives you enough runway to migrate a real workload and compare the billing side-by-side with S3.

Backblaze B2: The Price/Performance Winner

B2 is where the numbers get interesting. Storage runs $0.006 per GB per month. That's $6 per terabyte. S3 Standard is $23 per terabyte. B2 is 74% cheaper on storage before you factor in a single byte of egress.

Egress on B2 is free up to three times your monthly average stored data. For 100 GB stored, you get 300 GB of free egress per month. Our 100 GB egress benchmark is entirely within that window, so the egress bill is zero.

B2 also has a formal bandwidth alliance with Cloudflare. Egress from B2 through Cloudflare's CDN is completely free with no cap. This isn't a workaround or a gray-area arrangement. It's an explicit, documented partnership. If you're already using Cloudflare for DNS or CDN, you can front your B2 bucket and your egress cost drops to zero, permanently, regardless of volume.

The free tier gives you 10 GB of storage permanently, plus 2,500 free read and metadata API calls per day. For most dev and staging environments, you'll never pay a cent.

B2 does support Object Lock, which puts it ahead of some competitors for teams with compliance requirements around immutable storage.

Benchmark cost (100 GB stored, 100 GB egress): $0.60 storage + $0 egress = $0.60/month.

Best for: Any workload where storage volume and egress are both significant. Backup storage, media archives, static asset hosting, and anything fronted by Cloudflare CDN. B2 is the best cost-per-dollar option on this list for most independent developers and small teams.

Head-to-Head Comparison

Scenario: 100 GB stored, 100 GB egress per month. US region. Prices verified April 2026.

My Recommendation by Use Case

You want the lowest possible bill and you're starting fresh. Backblaze B2. It's not close. At $0.006/GB storage and zero egress within the free allowance (or zero forever with Cloudflare in front), nothing else competes on pure cost. Start with the permanent free tier and only pay when you grow past 10 GB.

You're already on DigitalOcean and want a simple, predictable bill. Spaces. The $5 flat rate, internal transfer pricing, and included CDN make it the obvious choice if you're not going to switch compute providers. New accounts get $200 in credit to try it with zero commitment.

You're running a large, consistent workload close to 1 TB per month. Vultr's flat-rate plans start making sense here. The economics improve significantly as you approach the included limits, and the predictability has real value for budgeting. Vultr gives new accounts $300 in credit to run a proper evaluation.

You have compliance requirements for immutable storage. S3 or B2. Both support Object Lock. DigitalOcean and Vultr don't, at least not as of this writing.

You need to store objects larger than 5 GB. S3 or B2. DigitalOcean Spaces and Vultr both cap at 5 GB per object, which rules them out for video, database dumps, and ML model checkpoints.

Do the Math for Your Actual Workload

The numbers I've run here are illustrative. Your storage volume, egress pattern, request volume, and existing cloud relationships all shift the outcome. A team pushing 10 TB per month out to end users is losing thousands of dollars a year on S3 egress. A team storing 50 GB with almost no reads might be fine anywhere.
