5 Awesome Amazon S3 Alternatives

Amazon S3 is the original object storage service and still the industry default for storing files, backups, and media in the cloud. It's battle-tested, massively scalable, and deeply integrated into the AWS ecosystem. But its pricing is anything but simple: S3 Standard starts at $0.023/GB/month, with additional charges for egress ($0.09/GB after the first 100 GB), API requests, and data retrieval depending on the storage class you pick. A modest 1 TB setup with regular downloads can easily cost $50-100/month once you factor in all the line items.

If you're looking for simpler pricing, lower costs, or want to avoid AWS vendor lock-in, there are excellent alternatives out there. Some offer zero egress fees, others give you S3-compatible APIs at a fraction of the price, and a few even keep your data in Europe for GDPR compliance.

Let's look at 5 awesome alternatives to Amazon S3!

1. Backblaze B2

Backblaze B2 is one of the most popular S3 alternatives, known for dead-simple pricing and rock-solid reliability. At $0.006/GB/month, storage costs roughly 1/4 of what you'd pay with S3 Standard, and there are no complicated storage tiers to worry about.

• Features: S3-compatible API, single storage class, 11 nines (99.999999999%) durability, free egress up to 3x your storage volume, free egress through CDN partners (Cloudflare, Fastly, bunny.net), lifecycle rules, object lock (immutability), server-side encryption, and a web-based file manager.
• Why You Should Use It: If you want the lowest per-GB storage price from a managed provider without sacrificing reliability, B2 is hard to beat. The generous free egress (3x storage) and CDN partnerships mean most users never pay for downloads at all. It's a great fit for backups, media storage, and archival.
• Why Not: B2 has only one storage class, so there's no equivalent to S3's Glacier tiers for ultra-cheap cold storage. Region selection is limited compared to AWS. The API, while S3-compatible, doesn't support every S3 feature (no server-side copy for large objects, for example).
• Pricing: $0.006/GB/month for storage. Egress is free up to 3x your average monthly storage, then $0.01/GB. First 10 GB of storage is free. No minimum storage duration and no API fees for uploads.

2. Cloudflare R2

Cloudflare R2 is Cloudflare's S3-compatible object storage built specifically to eliminate egress fees. If your workload involves serving files to users (images, videos, downloads), R2 can save you a fortune compared to S3's steep egress pricing.

• Features: Full S3 API compatibility, zero egress fees, Infrequent Access storage class ($0.01/GB), Workers integration for edge computing, Super Slurper for easy migration from S3, event notifications, custom domains, presigned URLs, and a generous free tier.
• Why You Should Use It: If your application serves a lot of data to end users, R2's zero egress model is a game changer. Pairing R2 with Cloudflare Workers lets you process files at the edge without roundtrips to an origin server. The free tier (10 GB storage, 10M reads/month) is generous enough for side projects.
• Why Not: Storage is pricier than Backblaze B2 or Wasabi at $0.015/GB/month. You pay per API operation (Class A: $4.50/million, Class B: $0.36/million), which can add up for high-request workloads. There's no cold archive tier comparable to S3 Glacier Deep Archive.
• Pricing: $0.015/GB/month for Standard storage, $0.01/GB for Infrequent Access. Zero egress fees. Free tier includes 10 GB storage, 1M Class A operations, and 10M Class B operations per month.

3. Wasabi

Wasabi markets itself as "hot cloud storage" with a flat-rate pricing model: one price per TB, no egress fees, no API fees. It's S3-compatible and positions itself as the simplest alternative for teams tired of AWS's complex billing.

• Features: Full S3 API compatibility, 11 nines durability, no egress or API charges, data centers in North America, Europe, and Asia-Pacific, object lock and immutability, bucket versioning, multi-user access with IAM policies, and AES-256 server-side encryption.
• Why You Should Use It: If you want truly predictable costs with zero surprises on your bill, Wasabi's flat-rate model is appealing. No egress fees and no API fees means you pay one number and that's it. It's a strong choice for large datasets, backups, and compliance archives where you need lots of storage but don't want to micromanage tiers.
• Why Not: There's a 1 TB minimum charge (you pay for 1 TB even if you store less), and a 90-day minimum storage duration (early deletion is still billed). Egress is technically "free" but capped at your active storage volume per month; exceed that ratio and Wasabi may throttle or restrict your account. These gotchas matter for small or bursty workloads.
• Pricing: $6.99/TB/month (increasing to $7.99/TB in July 2026). No egress fees, no API fees. 1 TB minimum charge and 90-day minimum retention apply. Reserved Capacity plans available for volume discounts.

4. Hetzner Object Storage

Hetzner Object Storage is a European S3-compatible storage service from Hetzner, the German cloud provider known for aggressive pricing. If GDPR compliance and data sovereignty matter to you, Hetzner keeps all your data in EU data centers.

• Features: S3-compatible API, data centers in Falkenstein, Nuremberg, and Helsinki (all EU), 1 TB storage and 1 TB egress included in the base price, up to 100 buckets, 100 TB per bucket, free internal traffic within Hetzner's network, and pay-as-you-go overage billing.
• Why You Should Use It: If you're already running servers on Hetzner (or want a European storage provider for GDPR reasons), this is the obvious pick. The base plan gives you 1 TB of storage and 1 TB of egress for just €4.99/month, making it one of the cheapest options on the market. Internal transfers between Hetzner services are free, which is great if your app servers are there too.
• Why Not: Hetzner Object Storage is still relatively new and has fewer features than mature providers like S3 or Backblaze. There's a 64 KB minimum billing size for small objects, which inflates costs if you store millions of tiny files. Region selection is limited to EU only.
• Pricing: €4.99/month base plan includes 1 TB storage + 1 TB egress. Overage: €0.0067/TB-hour for storage, €1.00/TB for egress. Free internal traffic and unlimited S3 API calls.

5. DigitalOcean Spaces

DigitalOcean Spaces is a developer-friendly object storage service with a built-in CDN. It's a natural fit if you're already using DigitalOcean Droplets, Kubernetes, or App Platform, and its flat subscription model keeps billing predictable.

• Features: S3-compatible API, built-in CDN at no extra cost, 250 GiB storage + 1 TiB outbound transfer included, Cold Storage class ($0.007/GiB), unlimited API requests, free internal transfers between DigitalOcean services, multiple data center regions, and per-bucket access control.
• Why You Should Use It: The built-in CDN is a standout feature that other providers charge extra for. If you're serving images, assets, or downloads globally, Spaces handles caching and distribution out of the box. The $5/month flat fee with 1 TiB of free egress makes budgeting simple for small to mid-size projects.
• Why Not: The included 250 GiB of storage is modest, and overage is $0.02/GiB, which gets expensive fast at scale. There's no free tier (unlike Cloudflare R2 or AWS S3). Performance and feature set are more basic compared to S3, and the Cold Storage tier is newer with fewer features than S3 Glacier.
• Pricing: $5/month includes 250 GiB storage + 1 TiB egress. Overage: $0.02/GiB storage, $0.01/GiB egress. Cold Storage at $0.007/GiB/month. Unlimited API requests included.

Conclusion

Each alternative shines in a different scenario: Backblaze B2 for the lowest per-GB storage costs, Cloudflare R2 for workloads with heavy downloads and zero egress fees, Wasabi for dead-simple flat-rate pricing on large datasets, Hetzner for European data sovereignty at rock-bottom prices, and DigitalOcean Spaces for developer convenience with a built-in CDN.

Amazon S3 remains the right choice when you need its deep AWS integration, dozens of storage classes, or the broadest global region coverage. But for most workloads, one of these alternatives can save you 50-80% while keeping full S3 API compatibility.
