5 S3-Compatible Storage Providers With No Egress Fees in 2026

Egress fees are one of the most annoying parts of object storage pricing.

Uploading data is easy. Storing data looks cheap. Then one day your users download a lot of files, your backup restore runs, your CDN misses cache, or your app exports a bunch of reports, and suddenly the storage bill has opinions.

This post compares S3-compatible storage providers with no egress fees or unusually friendly egress policies.

What counts as "no egress fees"?

Providers use different language here, so pay attention.

Some providers have truly free egress for the object storage product. Some include a generous allowance. Some have free egress but charge request fees. Some have no request fees but retention rules.

For this list, I included providers where egress is either free or meaningfully simpler than AWS S3 for common app workloads.

Quick comparison

1. Sliplane Object Storage

Sliplane Object Storage has the cleanest pricing model in this list for normal app storage.

You pay 5 EUR per 250 GB per month, excluding tax. The first GB is free. There are no egress fees, no ingress fees, and no request fees.

This is especially useful for apps where bandwidth is hard to predict: user uploads, generated images, exported PDFs, backups, file previews, and internal tools that suddenly become more popular than expected.

Sliplane does not charge per bucket, so splitting uploads, backups, staging assets, and customer files into separate buckets does not change the bill.

Use Sliplane if:

• You want no egress fees and no request fees.
• You want S3 compatibility.
• You want a German region.
• You want storage next to your app hosting.

Skip it if:

• You need deep archive storage.
• You need storage in many global regions.
• You need advanced S3 enterprise features.

2. Cloudflare R2

Cloudflare R2 is the most famous "no egress" S3 alternative.

Cloudflare lists R2 egress as free for Standard and Infrequent Access storage. Standard storage is $0.015 per GB-month. The free tier includes 10 GB-month of storage, 1 million Class A operations, and 10 million Class B operations per month.

The catch is operations. If your workload reads millions of tiny objects every day, Class B operations can become the line item to watch. Cloudflare's own pricing example for asset hosting shows reads can matter even when storage is tiny.

Use R2 if:

• You serve public assets.
• You already use Cloudflare.
• Egress is your biggest pain.
• You are comfortable tracking request classes.

Skip it if:

• You want no request fees.
• You want German/EU-first storage positioning.
• You do not use Cloudflare's ecosystem.

3. Wasabi

Wasabi is built around a simple pitch: hot cloud storage with no fees for egress or API requests.

As of July 2026, Wasabi lists pay-as-you-go pricing starting at $7.99 per TB per month. Wasabi is often a strong option for backups, media archives, and teams moving away from hyperscaler egress bills.

The thing to watch is retention and minimum billing behavior. Wasabi has historically been more opinionated about minimum storage duration than providers that bill purely on current usage. Always read the pricing FAQ before using it for short-lived temporary objects.

Use Wasabi if:

• You store large amounts of data.
• You want no egress and no API request fees.
• Your data tends to stay around for a while.

Skip it if:

• You frequently create and delete short-lived files.
• You want storage inside your app platform.
• You need a German provider specifically.

4. Backblaze B2

Backblaze B2 is not unlimited free egress, but it is friendlier than many classic cloud storage providers.

Backblaze lists B2 Cloud Storage starting at $6.95 per TB per month, free transactions, and free egress up to 3x average monthly data stored. Additional egress is listed at $0.01 per GB.

That model is very good for backups and archives where downloads are moderate compared to stored data.

Use Backblaze B2 if:

• You need cheap storage at TB scale.
• You mostly store backups or archives.
• Your downloads are usually below 3x stored data.

Skip it if:

• You need truly unlimited free egress.
• Your app serves files constantly.
• You want German storage.

5. IONOS Cloud Object Storage

IONOS Cloud Object Storage lists free API operations for PUT, COPY, POST, LIST, GET, and DELETE, plus free data storage writes and reads. Storage itself is charged per GB per 30 days.

Traffic is the part to read carefully. The IONOS pricing page says data transmission costs are not included and are charged according to traffic rules depending on source, destination, and bucket ownership.

So IONOS is not a pure no-egress product in the same simple sense as Sliplane or R2, but it can still be attractive if you are already in the IONOS Cloud ecosystem and understand the traffic model.

Use IONOS if:

• You want a German provider.
• You already use IONOS Cloud.
• API request fees are your main concern.

Skip it if:

• You want egress to be unambiguously free.
• You want a simple developer-first storage bill.
• You do not want to study traffic categories.

Which no-egress S3 provider should you choose?

Conclusion

No-egress storage does not always mean no surprise bills. You still need to check request fees, retrieval fees, minimum storage duration, storage class behavior, and traffic rules.

For app uploads and backups, the cleanest model is usually the one with the fewest line items.

If you want S3-compatible object storage with free egress, free requests, and a German region, Sliplane Object Storage is deliberately boring in the best possible way.
